A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS. (From Adams et al., Principles of Neurology, 6th ed, pp1049-57)
Peptides generated from AMYLOID BETA-PEPTIDES PRECURSOR. An amyloid fibrillar form of these peptides is the major component of amyloid plaques found in individuals with Alzheimer's disease and in aged individuals with trisomy 21 (DOWN SYNDROME). The peptide is found predominantly in the nervous system, but there have been reports of its presence in non-neural tissue.
Microtubule-associated proteins that are mainly expressed in neurons. Tau proteins constitute several isoforms and play an important role in the assembly of tubulin monomers into microtubules and in maintaining the cytoskeleton and axonal transport. Aggregation of specific sets of tau proteins in filamentous inclusions is the common feature of intraneuronal and glial fibrillar lesions (NEUROFIBRILLARY TANGLES; NEUROPIL THREADS) in numerous neurodegenerative disorders (ALZHEIMER DISEASE; TAUOPATHIES).
Amyloid beta-Protein Precursor
Abnormal structures located in various parts of the brain and composed of dense arrays of paired helical filaments (neurofilaments and microtubules). These double helical stacks of transverse subunits are twisted into left-handed ribbon-like filaments that likely incorporate the following proteins: (1) the intermediate filaments: medium- and high-molecular-weight neurofilaments; (2) the microtubule-associated proteins map-2 and tau; (3) actin; and (4) UBIQUITINS. As one of the hallmarks of ALZHEIMER DISEASE, the neurofibrillary tangles eventually occupy the whole of the cytoplasm in certain classes of cell in the neocortex, hippocampus, brain stem, and diencephalon. The number of these tangles, as seen in post mortem histology, correlates with the degree of dementia during life. Some studies suggest that tangle antigens leak into the systemic circulation both in the course of normal aging and in cases of Alzheimer disease.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
A major and the second most common isoform of apolipoprotein E. In humans, Apo E4 differs from APOLIPOPROTEIN E3 at only one residue 112 (cysteine is replaced by arginine), and exhibits a lower resistance to denaturation and greater propensity to form folded intermediates. Apo E4 is a risk factor for ALZHEIMER DISEASE and CARDIOVASCULAR DISEASES.
Amyloid Precursor Protein Secretases
An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness.
Integral membrane protein of Golgi and endoplasmic reticulum. Its homodimer is an essential component of the gamma-secretase complex that catalyzes the cleavage of membrane proteins such as NOTCH RECEPTORS and AMYLOID BETA-PEPTIDES precursors. PSEN1 mutations cause early-onset ALZHEIMER DISEASE type 3 that may occur as early as 30 years of age in humans.
A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.
Mild Cognitive Impairment
A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.
Mental Status Schedule
A curved elevation of GRAY MATTER extending the entire length of the floor of the TEMPORAL HORN of the LATERAL VENTRICLE (see also TEMPORAL LOBE). The hippocampus proper, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.
Magnetic Resonance Imaging
Lewy Body Disease
A neurodegenerative disease characterized by dementia, mild parkinsonism, and fluctuations in attention and alertness. The neuropsychiatric manifestations tend to precede the onset of bradykinesia, MUSCLE RIGIDITY, and other extrapyramidal signs. DELUSIONS and visual HALLUCINATIONS are relatively frequent in this condition. Histologic examination reveals LEWY BODIES in the CEREBRAL CORTEX and BRAIN STEM. SENILE PLAQUES and other pathologic features characteristic of ALZHEIMER DISEASE may also be present. (From Neurology 1997;48:376-380; Neurology 1996;47:1113-1124)
Age of Onset
Aspartic Acid Endopeptidases
Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system.
National Institute on Aging (U.S.)
Cerebral Amyloid Angiopathy
A heterogeneous group of sporadic or familial disorders characterized by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES. Clinical features include multiple, small lobar CEREBRAL HEMORRHAGE; cerebral ischemia (BRAIN ISCHEMIA); and CEREBRAL INFARCTION. Cerebral amyloid angiopathy is unrelated to generalized AMYLOIDOSIS. Amyloidogenic peptides in this condition are nearly always the same ones found in ALZHEIMER DISEASE. (from Kumar: Robbins and Cotran: Pathologic Basis of Disease, 7th ed., 2005)
An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
Loss of functional activity and trophic degeneration of nerve axons and their terminal arborizations following the destruction of their cells of origin or interruption of their continuity with these cells. The pathology is characteristic of neurodegenerative diseases. Often the process of nerve degeneration is studied in research on neuroanatomical localization and correlation of the neurophysiology of neural pathways.
Disease Models, Animal
Neurodegenerative disorders involving deposition of abnormal tau protein isoforms (TAU PROTEINS) in neurons and glial cells in the brain. Pathological aggregations of tau proteins are associated with mutation of the tau gene on chromosome 17 in patients with ALZHEIMER DISEASE; DEMENTIA; PARKINSONIAN DISORDERS; progressive supranuclear palsy (SUPRANUCLEAR PALSY, PROGRESSIVE); and corticobasal degeneration.
A chromosome disorder associated either with an extra chromosome 21 or an effective trisomy for chromosome 21. Clinical manifestations include hypotonia, short stature, brachycephaly, upslanting palpebral fissures, epicanthus, Brushfield spots on the iris, protruding tongue, small ears, short, broad hands, fifth finger clinodactyly, Simian crease, and moderate to severe INTELLECTUAL DISABILITY. Cardiac and gastrointestinal malformations, a marked increase in the incidence of LEUKEMIA, and the early onset of ALZHEIMER DISEASE are also associated with this condition. Pathologic features include the development of NEUROFIBRILLARY TANGLES in neurons and the deposition of AMYLOID BETA-PROTEIN, similar to the pathology of ALZHEIMER DISEASE. (Menkes, Textbook of Child Neurology, 5th ed, p213)
Genetic Predisposition to Disease
Intracytoplasmic, eosinophilic, round to elongated inclusions found in vacuoles of injured or fragmented neurons. The presence of Lewy bodies is the histological marker of the degenerative changes in LEWY BODY DISEASE and PARKINSON DISEASE but they may be seen in other neurological conditions. They are typically found in the substantia nigra and locus coeruleus but they are also seen in the basal forebrain, hypothalamic nuclei, and neocortex.
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS. (From Adams et al., Principles of Neurology, 6th ed, pp426-7)
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.
Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
A 34-kDa glycosylated protein. A major and most common isoform of apolipoprotein E. Therefore, it is also known as apolipoprotein E (ApoE). In human, Apo E3 is a 299-amino acid protein with a cysteine at the 112 and an arginine at the 158 position. It is involved with the transport of TRIGLYCERIDES; PHOSPHOLIPIDS; CHOLESTEROL; and CHOLESTERYL ESTERS in and out of the cells.
Chromosomes, Human, Pair 21
Monomeric Clathrin Assembly Proteins
A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism. (Adams et al., Principles of Neurology, 6th ed, p1059, pp1067-75)
One of three major isoforms of apolipoprotein E. In humans, Apo E2 differs from APOLIPOPROTEIN E3 at one residue 158 where arginine is replaced by cysteine (R158--C). In contrast to Apo E3, Apo E2 displays extremely low binding affinity for LDL receptors (RECEPTORS, LDL) which mediate the internalization and catabolism of lipoprotein particles in liver cells. ApoE2 allelic homozygosity is associated with HYPERLIPOPROTEINEMIA TYPE III.
A neurobehavioral syndrome associated with bilateral medial temporal lobe dysfunction. Clinical manifestations include oral exploratory behavior; tactile exploratory behavior; hypersexuality; BULIMIA; MEMORY DISORDERS; placidity; and an inability to recognize objects or faces. This disorder may result from a variety of conditions, including CRANIOCEREBRAL TRAUMA; infections; ALZHEIMER DISEASE; PICK DISEASE OF THE BRAIN; and CEREBROVASCULAR DISORDERS.
A benzazepine derived from norbelladine. It is found in GALANTHUS and other AMARYLLIDACEAE. It is a cholinesterase inhibitor that has been used to reverse the muscular effects of GALLAMINE TRIETHIODIDE and TUBOCURARINE and has been studied as a treatment for ALZHEIMER DISEASE and other central nervous system disorders.
Frontotemporal Lobar Degeneration
Heterogeneous group of neurodegenerative disorders characterized by frontal and temporal lobe atrophy associated with neuronal loss, gliosis, and dementia. Patients exhibit progressive changes in social, behavioral, and/or language function. Multiple subtypes or forms are recognized based on presence or absence of TAU PROTEIN inclusions. FTLD includes three clinical syndromes: FRONTOTEMPORAL DEMENTIA, semantic dementia, and PRIMARY PROGRESSIVE NONFLUENT APHASIA.
A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.
LDL-Receptor Related Proteins
CA2 Region, Hippocampal
Nerve Fibers, Myelinated
A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the myelinated nerve fibers are completely encased in a MYELIN SHEATH. They are fibers of relatively large and varied diameters. Their NEURAL CONDUCTION rates are faster than those of the unmyelinated nerve fibers (NERVE FIBERS, UNMYELINATED). Myelinated nerve fibers are present in somatic and autonomic nerves.
Glycogen Synthase Kinase 3
Persons who provide care to those who need supervision or assistance in illness or disability. They may provide the care in the home, in a hospital, or in an institution. Although caregivers include trained medical, nursing, and other health personnel, the concept also refers to parents, spouses, or other family members, friends, members of the clergy, teachers, social workers, fellow patients.
Severity of Illness Index
Cyclin-Dependent Kinase 5
A republic in the Greater Antilles in the West Indies. Its capital is Santo Domingo. With Haiti, it forms the island of Hispaniola - the Dominican Republic occupying the eastern two thirds, and Haiti, the western third. It was created in 1844 after a revolt against the rule of President Boyer over the entire island of Hispaniola, itself visited by Columbus in 1492 and settled the next year. Except for a brief period of annexation to Spain (1861-65), it has been independent, though closely associated with the United States. Its name comes from the Spanish Santo Domingo, Holy Sunday, with reference to its discovery on a Sunday. (From Webster's New Geographical Dictionary, 1988, p338, 506 & Room, Brewer's Dictionary of Names, 1992, p151)
Psychiatric Status Rating Scales
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Image Processing, Computer-Assisted
The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.
Amino Acid Sequence
A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.
Polymorphism, Single Nucleotide
Reproducibility of Results
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
Type III intermediate filament proteins that assemble into neurofilaments, the major cytoskeletal element in nerve axons and dendrites. They consist of three distinct polypeptides, the neurofilament triplet. Types I, II, and IV intermediate filament proteins form other cytoskeletal elements such as keratins and lamins. It appears that the metabolism of neurofilaments is disturbed in Alzheimer's disease, as indicated by the presence of neurofilament epitopes in the neurofibrillary tangles, as well as by the severe reduction of the expression of the gene for the light neurofilament subunit of the neurofilament triplet in brains of Alzheimer's patients. (Can J Neurol Sci 1990 Aug;17(3):302)
Aphasia, Primary Progressive
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE. (From Brain 1998 Jan;121(Pt 1):115-26)
Small proteinaceous infectious particles which resist inactivation by procedures that modify NUCLEIC ACIDS and contain an abnormal isoform of a cellular protein which is a major and necessary component. The abnormal (scrapie) isoform is PrPSc (PRPSC PROTEINS) and the cellular isoform PrPC (PRPC PROTEINS). The primary amino acid sequence of the two isoforms is identical. Human diseases caused by prions include CREUTZFELDT-JAKOB SYNDROME; GERSTMANN-STRAUSSLER SYNDROME; and INSOMNIA, FATAL FAMILIAL.
The compound is given by intravenous injection to do POSITRON-EMISSION TOMOGRAPHY for the assessment of cerebral and myocardial glucose metabolism in various physiological or pathological states including stroke and myocardial ischemia. It is also employed for the detection of malignant tumors including those of the brain, liver, and thyroid gland. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1162)
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Genome-Wide Association Study
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Sensitivity and Specificity
Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.
Protein Processing, Post-Translational
Any of various enzymatically catalyzed post-translational modifications of PEPTIDES or PROTEINS in the cell of origin. These modifications include carboxylation; HYDROXYLATION; ACETYLATION; PHOSPHORYLATION; METHYLATION; GLYCOSYLATION; ubiquitination; oxidation; proteolysis; and crosslinking and result in changes in molecular weight and electrophoretic motility.
Hydrocephalus, Normal Pressure
A form of compensated hydrocephalus characterized clinically by a slowly progressive gait disorder (see GAIT DISORDERS, NEUROLOGIC), progressive intellectual decline, and URINARY INCONTINENCE. Spinal fluid pressure tends to be in the high normal range. This condition may result from processes which interfere with the absorption of CSF including SUBARACHNOID HEMORRHAGE, chronic MENINGITIS, and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp631-3)
Drugs intended to prevent damage to the brain or spinal cord from ischemia, stroke, convulsions, or trauma. Some must be administered before the event, but others may be effective for some time after. They act by a variety of mechanisms, but often directly or indirectly minimize the damage produced by endogenous excitatory amino acids.
Analysis of Variance
A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)
Enzyme that is a major constituent of kidney brush-border membranes and is also present to a lesser degree in the brain and other tissues. It preferentially catalyzes cleavage at the amino group of hydrophobic residues of the B-chain of insulin as well as opioid peptides and other biologically active peptides. The enzyme is inhibited primarily by EDTA, phosphoramidon, and thiorphan and is reactivated by zinc. Neprilysin is identical to common acute lymphoblastic leukemia antigen (CALLA Antigen), an important marker in the diagnosis of human acute lymphocytic leukemia. There is no relationship with CALLA PLANT.
Active immunization where vaccine is administered for therapeutic or preventive purposes. This can include administration of immunopotentiating agents such as BCG vaccine and Corynebacterium parvum as well as biological response modifiers such as interferons, interleukins, and colony-stimulating factors in order to directly stimulate the immune system.
In tissue culture, hairlike projections of neurons stimulated by growth factors and other molecules. These projections may go on to form a branched tree of dendrites or a single axon or they may be reabsorbed at a later stage of development. "Neurite" may refer to any filamentous or pointed outgrowth of an embryonal or tissue-culture neural cell.
Brief Psychiatric Rating Scale
A scale comprising 18 symptom constructs chosen to represent relatively independent dimensions of manifest psychopathology. The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses. (From Hersen, M. and Bellack, A.S., Dictionary of Behavioral Assessment Techniques, p. 87)
Alzheimer's disease: clues from flies and worms. (1/11292)Presenilin mutations give rise to familial Alzheimer's disease and result in elevated production of amyloid beta peptide. Recent evidence that presenilins act in developmental signalling pathways may be the key to understanding how senile plaques, neurofibrillary tangles and apoptosis are all biochemically linked. (+info)
Parametric mapping of cerebral blood flow deficits in Alzheimer's disease: a SPECT study using HMPAO and image standardization technique. (2/11292)This study assessed the accuracy and reliability of Automated Image Registration (AIR) for standardization of brain SPECT images of patients with Alzheimer's disease (AD). Standardized cerebral blood flow (CBF) images of patients with AD and control subjects were then used for group comparison and covariance analyses. METHODS: Thirteen patients with AD at an early stage (age 69.8+/-7.1 y, Clinical Dementia Rating Score 0.5-1.0, Mini-Mental State Examination score 19-23) and 20 age-matched normal subjects (age 69.5+/-8.3 y) participated in this study. 99mTc-hexamethyl propylenamine oxime (HMPAO) brain SPECT and CT scans were acquired for each subject. SPECT images were transformed to a standard size and shape with the help of AIR. Accuracy of AIR for spatial normalization was evaluated by an index calculated on SPECT images. Anatomical variability of standardized target images was evaluated by measurements on corresponding CT scans, spatially normalized using transformations established by the SPECT images. Realigned brain SPECT images of patients and controls were used for group comparison with the help of statistical parameter mapping. Significant differences were displayed on the respective voxel to generate three-dimensional Z maps. CT scans of individual subjects were evaluated by a computer program for brain atrophy. Voxel-based covariance analysis was performed on standardized images with ages and atrophy indices as independent variables. RESULTS: Inaccuracy assessed by functional data was 2.3%. The maximum anatomical variability was 4.9 mm after standardization. Z maps showed significantly decreased regional CBF (rCBF) in the frontal, parietal and temporal regions in the patient group (P < 0.001). Covariance analysis revealed that the effects of aging on rCBF were more pronounced compared with atrophy, especially in intact cortical areas at an early stage of AD. Decrease in rCBF was partly due to senility and atrophy, however these two factors cannot explain all the deficits. CONCLUSION: AIR can transform SPECT images of AD patients with acceptable accuracy without any need for corresponding structural images. The frontal regions of the brain, in addition to parietal and temporal lobes, may show reduced CBF in patients with AD even at an early stage of dementia. The reduced rCBF in the cortical regions cannot be explained entirely by advanced atrophy and fast aging process. (+info)
Proteolytic processing of the Alzheimer's disease amyloid precursor protein within its cytoplasmic domain by caspase-like proteases. (3/11292)Alzheimer's disease is characterized by neurodegeneration and deposition of betaA4, a peptide that is proteolytically released from the amyloid precursor protein (APP). Missense mutations in the genes coding for APP and for the polytopic membrane proteins presenilin (PS) 1 and PS2 have been linked to familial forms of early-onset Alzheimer's disease. Overexpression of presenilins, especially that of PS2, induces increased susceptibility for apoptosis that is even more pronounced in cells expressing presenilin mutants. Additionally, presenilins themselves are targets for activated caspases in apoptotic cells. When we analyzed APP in COS-7 cells overexpressing PS2, we observed proteolytic processing close to the APP carboxyl terminus. Proteolytic conversion was increased in the presence of PS2-I, which encodes one of the known PS2 pathogenic mutations. The same proteolytic processing occurred in cells treated with chemical inducers of apoptosis, suggesting a participation of activated caspases in the carboxyl-terminal truncation of APP. This was confirmed by showing that specific caspase inhibitors blocked the apoptotic conversion of APP. Sequence analysis of the APP cytosolic domain revealed a consensus motif for group III caspases ((IVL)ExD). Mutation of the corresponding Asp664 residue abolished cleavage, thereby identifying APP as a target molecule for caspase-like proteases in the pathways of programmed cellular death. (+info)
Microvessels from Alzheimer's disease brains kill neurons in vitro. (4/11292)Understanding the pathogenesis of Alzheimer's disease is of widespread interest because it is an increasingly prevalent disorder that is progressive, fatal, and currently untreatable. The dementia of Alzheimer's disease is caused by neuronal cell death. We demonstrate for the first time that blood vessels isolated from the brains of Alzheimer's disease patients can directly kill neurons in vitro. Either direct co-culture of Alzheimer's disease microvessels with neurons or incubation of cultured neurons with conditioned medium from microvessels results in neuronal cell death. In contrast, vessels from elderly nondemented donors are significantly (P<0.001) less lethal and brain vessels from younger donors are not neurotoxic. Neuronal killing by either direct co-culture with Alzheimer's disease microvessels or conditioned medium is dose- and time-dependent. Neuronal death can occur by either apoptotic or necrotic mechanisms. The microvessel factor is neurospecific, killing primary cortical neurons, cerebellar granule neurons, and differentiated PC-12 cells, but not non-neuronal cell types or undifferentiated PC-12 cells. Appearance of the neurotoxic factor is decreased by blocking microvessel protein synthesis with cycloheximide. The neurotoxic factor is soluble and likely a protein, because its activity is heat labile and trypsin sensitive. These findings implicate a novel mechanism of vascular-mediated neuronal cell death in Alzheimer's disease. (+info)
Specific regional transcription of apolipoprotein E in human brain neurons. (5/11292)In central nervous system injury and disease, apolipoprotein E (APOE, gene; apoE, protein) might be involved in neuronal injury and death indirectly through extracellular effects and/or more directly through intracellular effects on neuronal metabolism. Although intracellular effects could clearly be mediated by neuronal uptake of extracellular apoE, recent experiments in injury models in normal rodents and in mice transgenic for the human APOE gene suggest the additional possibility of intraneuronal synthesis. To examine whether APOE might be synthesized by human neurons, we performed in situ hybridization on paraffin-embedded and frozen brain sections from three nondemented controls and five Alzheimer's disease (AD) patients using digoxigenin-labeled antisense and sense cRNA probes to human APOE. Using the antisense APOE probes, we found the expected strong hybridization signal in glial cells as well as a generally fainter signal in selected neurons in cerebral cortex and hippocampus. In hippocampus, many APOE mRNA-containing neurons were observed in sectors CA1 to CA4 and the granule cell layer of the dentate gyrus. In these regions, APOE mRNA containing neurons could be observed adjacent to nonhybridizing neurons of the same cell class. APOE mRNA transcription in neurons is regionally specific. In cerebellar cortex, APOE mRNA was seen only in Bergmann glial cells and scattered astrocytes but not in Purkinje cells or granule cell neurons. ApoE immunocytochemical localization in semi-adjacent sections supported the selectivity of APOE transcription. These results demonstrate the expected result that APOE mRNA is transcribed and expressed in glial cells in human brain. The important new finding is that APOE mRNA is also transcribed and expressed in many neurons in frontal cortex and human hippocampus but not in neurons of cerebellar cortex from the same brains. This regionally specific human APOE gene expression suggests that synthesis of apoE might play a role in regional vulnerability of neurons in AD. These results also provide a direct anatomical context for hypotheses proposing a role for apoE isoforms on neuronal cytoskeletal stability and metabolism. (+info)
Increased phosphoglycerate kinase in the brains of patients with Down's syndrome but not with Alzheimer's disease. (6/11292)Impaired glucose metabolism in Down's syndrome (DS) has been well-documented in vivo, although information on the underlying biochemical defect is limited and no biochemical studies on glucose handling enzymes have been carried out in the brain. Through gene hunting in fetal DS brain we found an overexpressed sequence homologous to the phosphoglycerate kinase (PGK) gene. This finding was studied further by investigating the activity levels of this key enzyme of carbohydrate metabolism in the brains of patients with DS. PGK activity was determined in five brain regions of nine patients with DS, nine patients with Alzheimer's disease and 14 controls. PGK activity was significantly elevated in the frontal, occipital and temporal lobe and in the cerebellum of patients with DS. PGK activity in corresponding brain regions of patients with Alzheimer's disease was comparable with controls. We conclude that our findings complement previously published data on impaired brain glucose metabolism in DS evaluated by positron emission tomography in clinical studies. Furthermore, we show that in DS, impaired glucose metabolism, represented by increased PGK activity, is a specific finding rather than a secondary phenomenon simply due to neurodegeneration or atrophy. These observations are also supported by data from subtractive hybridization, showing overexpressed PGK in DS brains at the transcriptional level early in life. (+info)
Translation of the alzheimer amyloid precursor protein mRNA is up-regulated by interleukin-1 through 5'-untranslated region sequences. (7/11292)The amyloid precursor protein (APP) has been associated with Alzheimer's disease (AD) because APP is processed into the beta-peptide that accumulates in amyloid plaques, and APP gene mutations can cause early onset AD. Inflammation is also associated with AD as exemplified by increased expression of interleukin-1 (IL-1) in microglia in affected areas of the AD brain. Here we demonstrate that IL-1alpha and IL-1beta increase APP synthesis by up to 6-fold in primary human astrocytes and by 15-fold in human astrocytoma cells without changing the steady-state levels of APP mRNA. A 90-nucleotide sequence in the APP gene 5'-untranslated region (5'-UTR) conferred translational regulation by IL-1alpha and IL-1beta to a chloramphenicol acetyltransferase (CAT) reporter gene. Steady-state levels of transfected APP(5'-UTR)/CAT mRNAs were unchanged, whereas both base-line and IL-1-dependent CAT protein synthesis were increased. This APP mRNA translational enhancer maps from +55 to +144 nucleotides from the 5'-cap site and is homologous to related translational control elements in the 5'-UTR of the light and and heavy ferritin genes. Enhanced translation of APP mRNA provides a mechanism by which IL-1 influences the pathogenesis of AD. (+info)
Early phenotypic changes in transgenic mice that overexpress different mutants of amyloid precursor protein in brain. (8/11292)Transgenic mice overexpressing different forms of amyloid precursor protein (APP), i.e. wild type or clinical mutants, displayed an essentially comparable early phenotype in terms of behavior, differential glutamatergic responses, deficits in maintenance of long term potentiation, and premature death. The cognitive impairment, demonstrated in F1 hybrids of the different APP transgenic lines, was significantly different from nontransgenic littermates as early as 3 months of age. Biochemical analysis of secreted and membrane-bound APP, C-terminal "stubs," and Abeta(40) and Abeta(42) peptides in brain indicated that no single intermediate can be responsible for the complex of phenotypic dysfunctions. As expected, the Abeta(42) levels were most prominent in APP/London transgenic mice and correlated directly with the formation of amyloid plaques in older mice of this line. Plaques were associated with immunoreactivity for hyperphosphorylated tau, eventually signaling some form of tau pathology. In conclusion, the different APP transgenic mouse lines studied display cognitive deficits and phenotypic traits early in life that dissociated in time from the formation of amyloid plaques and will be good models for both early and late neuropathological and clinical aspects of Alzheimer's disease.

Early-onset Alzheimers disease may be detected through changes in the eye - Mental Daily
New findings in the journal Alzheimers & Dementia: Diagnosis, Assessment & Disease Monitoring may offer new insight into the detection of early-onset Alzheimers disease through changes in the eye.. According to researchers at Johns Hopkins Wilmer Eye Institute, measuring blood flow in the back of the eye might be a route for early detection of the neurodegenerative disease.. For the study, 13 participants were examined. The participants had been diagnosed with an uncommon early-onset Alzheimers disease.. Through optical coherence tomography angiography (OCTA), researchers were able to examine the blood vessels in the back of the eyes of the patients. The disease is known to be marked by mutations established in three separate genes.. From the findings: early-stage (ES) carriers had significantly greater capillary blood flow than controls and late-stage (LS) carriers. ES and LS carriers had significantly greater capillary blood flow heterogeneity than controls. There was no difference between ...

fMRI studies of associative encoding in young and elderly controls and mild Alzheimers disease | Journal of Neurology,...
These findings suggest that the functional neuroanatomical alterations underlying explicit memory changes in mild Alzheimers disease differ from those seen with normal aging. Particularly striking was the fact that the regions showing the greatest decreases in activation in the patients with mild Alzheimers disease compared with the elderly controls were in the hippocampal formation. We hypothesise that this is the result of the extensive neuronal loss (in conjunction with neuritic plaques and neurofibrillary tangles) that develops early in the course of Alzheimers disease.3 It is likely that regional atrophy is also at least partially responsible for the decreased hippocampal activation in Alzheimers disease.16 However, this is unlikely to be the entire explanation for our findings, as we saw little evidence of paradigm linked activation in the hippocampus in six of the seven Alzheimer patients when the MR signal was sampled within a small section of the hippocampus, guided by each ...
Xanax, Valium may boost pneumonia risk in Alzheimers patients - WSFA.com Montgomery Alabama news.
HealthDay News) -- Alzheimers patients given sedatives such as Valium or Xanax may have an increased risk for pneumonia, a new study warns.. People with Alzheimers disease are often given these drugs, called benzodiazepines, over the long term, the researchers said.. Examples of benzodiazepines include alprazolam (Xanax), clonazepam (Klonopin), diazepam (Valium), and lorazepam (Ativan).. An increased risk of pneumonia is an important finding to consider in treatment of patients with Alzheimer disease. Pneumonia often leads to admission to hospital, and patients with dementia are at increased risk of death related to pneumonia, Dr. Heidi Taipale, of Kuopio Research Center of Geriatric Care at the University of Eastern Finland, and co-authors wrote.. For the study, the researchers reviewed data from nearly 50,000 Alzheimers patients in Finland. The patients average age was 80 and about two-thirds were women.. The study found that people with Alzheimers who took benzodiazepines were 30 ...
Alzheimers Association International Conference on Alzheimers Disease 2010 | ALZFORUM
Guided by the latest biomarker and imaging data, scientists have drafted a new set of diagnostic research criteria redefining Alzheimer disease as a condition that develops-and eventually could warrant intervention-decades prior to obvious symptoms. Most clinicians welcomed the changes, which were proposed last month at the International Conference on Alzheimers Disease (ICAD) in Honolulu, Hawaii, but some questioned the benefit of earlier diagnosis while there is yet no way to stop the disease in its tracks (see ARF related news story). Amid this debate looms the critical question of how well biomarkers can predict who among the cognitively normal is heading toward dementia and, eventually, full-blown AD. This report recaps a sampling of ICAD studies that address this issue. By and large, the data suggest that seniors who appear normal on cognitive tests, but nonetheless suspect their memory is off, or who have high brain amyloid or other pathological reads, may already be quietly on the ...

Logistic regression analyses revealed a significant 3-way interaction between APO-E e4 genotypes (APO-E4), CST3 G/G genotype and age/age of onset on AD diagnosis (p,.05) suggesting that the genetic risk changes differentially for APO-E or CST3 as a function of age. We stratified our sample based on age/age of onset of 80+yrs versus younger. In the younger group (231 cases; 86 controls) APOE4 conferred significant risk for AD (p,.0001) while CST3 genotype did not (p=.09). In the 80+ group (50 cases; 81 controls) APOE4 no longer ...
Dental health care for Alzheimers patients - Delta Dental
Dental health problems in Alzheimers patients can lead to pain, unmanageable behavior and extensive dental treatment. Yet, the dental needs of Alzheimers patients are often overlooked, usually for very understandable reasons: the patients forgetfulness results in unintentional dental neglect; medications may cause chronic dry mouth (reduction in the healthy flow of saliva) that can lead to tooth decay; patients and their families lose contact with their dentist because they are focused on other health issues.. Good dental health can make eating and digesting food easier for an Alzheimers patient, improving the overall quality of life. If you are a caregiver for someone suffering from Alzheimers, here are some tips and techniques from the Alzheimers Association to assist your loved one in maintaining good oral health.. ...

Brain atrophy may predict risk for early Alzheimers disease | About memory
A study involving 159 older adults (average age 76) has confirmed that the amount of brain tissue in specific regions is a predictor of Alzheimers disease development. Of the 159 people, 19 were classified as at high risk on the basis of the smaller size of nine small regions previously shown to be vulnerable to Alzheimers), and 24 as low risk. The regions, in order of importance, are the medial temporal, inferior temporal, temporal pole, angular gyrus, superior parietal, superior frontal, inferior frontal cortex, supramarginal gyrus, precuneus.. There was no difference between the three risk groups at the beginning of the study on global cognitive measures (MMSE; Alzheimers Disease Assessment Scale-cognitive subscale; Clinical Dementia Rating-sum of boxes), or in episodic memory. The high-risk group did perform significantly more slowly on the Trail-making test part B, with similar trends on the Digit Symbol and Verbal Fluency tests.. After three years, 125 participants were re-tested. Nine ...

Plasma ABeta as a Surrogate Genetic Marker for Load - Alzheimers Disease Pathogenesis Lab: Steven G. Younkin - Mayo Clinic...
The identification of mutations in the APP, PS1, and PS2 genes that cause early-onset familial Alzheimers disease (AD), the demonstration that these mutations all increase Abeta42, and the discovery of an association between Apolipoprotein E4 and late-onset Alzheimers disease have dramatically improved our understanding of Alzheimers disease. It is clear, however, that much of the genetic risk in late onset Alzheimers disease remains unexplained. Current strategies to identify other genes that affect late-onset Alzheimers disease have met with limited success often because of the difficulty associated with obtaining late-onset families with sufficient power for reliable linkage analysis. Genetic studies using large numbers of small families or sib-pairs, to increase the power of the analysis, are also currently being performed by several groups however difficulties with the non-replication of positive loci, identified by different studies, has continued. It will also be difficult to ...
A Story about early-onset Alzheimers Disease | Stannah
The first thing we must bear in mind is that Alzheimers disease isnt a normal part of aging. Thats how Alzheimers differs from Dementia. However, it is fair to say that Alzheimers disease is one of the most common forms of Dementia (70% of all cases). It causes global cognitive deterioration, behavioral disturbances and diffused cortical atrophy associated with neuronal degeneration. Although its prevalence is much higher in the senior population, it is also considered the most frequent form of dementia among those under-65. However, the 65 years mark is merely based on sociological aspects, and it has no biological significance in clinical practice.. What Alice faces is early-onset Alzheimers, a form of the disease that is far rarer than common Alzheimers disease, and often affects people in their prime, regardless of how mentally active they are. This is because early-onset Alzheimers is a genetically conditioned disease, with few environmental factors.. ...

The Good News Today - FAILED amyloid plaque theory: Scientists dumbfounded over Alzheimers disease after 20 years of research
Naturalhealth365) For the past two decades, researchers have focused on amyloid plaque - deposits typically found in the brains of patients with Alzheimers disease - as both an indicator and a cause of the disease. But, the real problem has become abundantly clear!. In reality, despite years of research (and massive financial backing by Big Pharma), scientists are no closer to a successful method of treatment.. Thomas J. Lewis, PhD - a researcher, author and leading expert on diseases of aging - says he knows the reason for the epic lack of progress on Alzheimers disease, which currently affects 5.7 million Americans. The biggest myth, says Dr. Lewis, is that Alzheimers disease is caused by amyloid plaque.. Several pharmaceutical companies, including GlaxoSmithKline and Johnson and Johnson, have conducted clinical trials on Alzheimers disease patients using anti-amyloid drugs.. These medications are intended to target amyloid plaques, inhibiting their ability to form the neurofibrillary ...

Sleep Apnea in Early to Mid-Stage Alzheimer's Disease - Full Text View - ClinicalTrials.gov
Obstructive sleep apnea (OSA) is much more common in the elderly than in the young; the latest studies show prevalence between 45% and 62% in individuals over 60. It is even higher in patients with dementia such as Alzheimer patients.. Several trials in elderly patients showed modified cognitive functions, particularly executive and attentional functions, in patients with respiratory sleep disorder. However the benefit of CPAP (Continuous Positive Airway Pressure) ventilation for Alzheimer patients is still controversial, as there are few studies documenting its effects on dementia patients cognitive abilities, and clinicians appear reluctant to prescribe this type of treatment.. The investigators must keep in mind that Alzheimer patients suffer significant sleep disorders; advanced- stage patients spend 40% of the night awake and are drowsy a large part of the day. In dementia patients, sleep disorder is a major cause of hospitalization and institutionalization. The prevalence of obstructive ...

LBP-1c/CP2/LSF gene polymorphism and risk of sporadic Alzheimers disease | Journal of Neurology, Neurosurgery & Psychiatry
The ε4 allele of apolipoprotein E (ApoE) accounts for an estimated 45-60% of the genetic risk for late onset sporadic Alzheimers disease, suggesting that it may be possible to identify other genetic loci that could account for the remaining risk associated with this disease. Recently, a biallelic polymorphism (G/A) in the 3′ untranslated region (UTR) of the transcription factor LBP-1c/CP2/LSF (for brevity, CP2) has been implicated in Alzheimers disease susceptibility, with the 3′-UTR A allele being associated with a reduction in the risk of sporadic Alzheimers disease.1-3 The CP2 gene is a plausible candidate for influencing Alzheimers disease risk: it is located near the LDL receptor related protein gene within the Alzheimers disease linkage region on chromosome 12; it controls the expression of several genes (α2 macroglobulin, glycogen synthase kinase-3β); and it interacts with different proteins (serum amyloid A3, interleukin 1α, tumour necrosis factor α, and Fe65 protein) and ...

Here, we report that we used sandwich enzyme-linked immunoabsorbent assay to quantitate various Aβ species in the frontal cortex of AD brains homogenized in 70% formic acid. We found that most of the Aβ species detected in rapidly autopsied brains (,3 h) with sporadic AD were Aβ1-x and Aβ1-42, as well as Aβx-42. To establish a linkage between Aβ levels and BACE, we examined BACE protein, mRNA expression and ...

Presenile Alzheimer dementia characterized by amyloid angiopathy and large amyloid core type senile plaques in the APP 692Ala--...
Mutations at codons 717 and 670/671 in the amyloid precursor protein (APP) are rare genetic causes of familial Alzheimers disease (AD). A mutation at codon 693 of APP has also been described as the genetic defect in hereditary cerebral hemorrhage with amyloidosis of the Dutch type (HCHWA-D). We have reported a APP692Ala--|Gly (Flemish) mutation as a cause of intracerebral hemorrhage and presenile dementia diagnosed as probable AD in a Dutch family. We now describe the post-mortem examination of two demented patients with the APP692 mutation. The neuropathological findings support the diagnosis of AD. Leptomeningial and parenchymal vessels showed extensive deposition of Abeta amyloid protein. Numerous senile plaques consisted of large Abeta amyloid cores, often measuring more than 30 microm in diameter and were surrounded by a fine meshwork of dystrophic neurites. In addition, there were a large number of paired helical filaments in pyramidal neurons and dystrophic neurites. Our findings show that the

Revised Criteria Could Reclassify Many With Mild Alzheimer Dementia - Redorbit
Many patients currently diagnosed with very mild or mild Alzheimer disease dementia could potentially be reclassified as having mild cognitive impairment (MCI) under revised criteria for that condition, according to a report published Online First by Archives of Neurology, one of the JAMA/Archives journals.. The National Institute on Aging and the Alzheimers Association convened a work group to update criteria for MCI, and the revised criteria allow considerable latitude as to what represents functional independence, writes the studys sole author, John C. Morris, M.D., of Washington University School of Medicine in St. Louis. For example, mild problems performing daily activities such as shopping, paying bills and cooking are permissible, as is dependency on aids or assistance to complete those tasks.. In this study, the functional ratings of patients enrolled at federally funded Alzheimers Disease Centers with clinical and cognitive data maintained by the National Alzheimers ...
Brain Ischemia: Alzheimers Disease Mechanisms - Nova Science Publishers
This new book presents a summary of Alzheimers disease-related ischemic protein changes and gene expression as risk factors for the late-onset of sporadic Alzheimers disease, and their role in Alzheimers disease ischemic etiology. Ischemic brain changes were noted in the staining of different parts of an amyloid protein precursor, presenilin 1 and 2, tau protein, alfa-synuclein, and apolipoproteins A1, E and J.. Current advances in understanding the ischemic etiology of Alzheimers disease has revealed dysregulation of Alzheimers disease-associated genes including presenilin 1 and 2, β-secretase, amyloid protein precursor, apoptosis, autophagy, mitophagy, and tau protein. This book presents the relationship between these genes, dysregulated by cerebral ischemia, and the cellular and tissue neuropathology characteristic of Alzheimers disease. This book draws attention to the latest research confirming the theory that Alzheimers disease-related proteins and genes play an important role in ...
Pyroglutamate Abeta pathology in APP/PS1KI mice, sporadic and familial Alzheimers disease cases
The presence of Abeta(pE3) (N-terminal truncated Abeta starting with pyroglutamate) in Alzheimers disease (AD) has received considerable attention since the discovery that this peptide represents a dominant fraction of Abeta peptides in senile plaques of AD brains. This was later confirmed by other reports investigating AD and Downs syndrome postmortem brain tissue. Importantly, Abeta(pE3) has a higher aggregation propensity, and stability, and shows an increased toxicity compared to full-length Abeta. We have recently shown that intraneuronal accumulation of Abeta(pE3) peptides induces a severe neuron loss and an associated neurological phenotype in the TBA2 mouse model for AD. Given the increasing interest in Abeta(pE3), we have generated two novel monoclonal antibodies which were characterized as highly specific for Abeta(pE3) peptides and herein used to analyze plaque deposition in APP/PS1KI mice, an AD model with severe neuron loss and learning deficits. This was compared with the plaque ...
Rates of Decline in Alzheimer Disease Decrease with Age
Author(s): Holland, Dominic; Desikan, Rahul S.; Dale, Anders M.; McEvoy, Linda K. | Abstract: Age is the strongest risk factor for sporadic Alzheimer disease (AD), yet the effects of age on rates of clinical decline and brain atrophy in AD have been largely unexplored. Here, we examined longitudinal rates of change as a function of baseline age for measures of clinical decline and structural MRI-based regional brain atrophy, in cohorts of AD, mild cognitive impairment (MCI), and cognitively healthy (HC) individuals aged 65 to 90 years (total n = 723). The effect of age was modeled using mixed effects linear regression. There was pronounced reduction in rates of clinical decline and atrophy with age for AD and MCI individuals, whereas HCs showed increased rates of clinical decline and atrophy with age. This resulted in convergence in rates of change for HCs and patients with advancing age for several measures. Baseline cerebrospinal fluid densities of AD-relevant proteins, Aβ1-42, tau, and phospho
American Mindfulness Research Association Adding mindfulness to meds helps Alzheimers patients - American Mindfulness Research...
Alzheimers Disease is a progressive neurodegenerative illness characterized by short-term memory loss, disorientation, and impairments in socialization, self-care and behavioral regulation. It is primarily a disease of old age and affects over 5,000,000 Americans. Medications are often prescribed to manage its symptoms, but no medication has been shown to halt or delay the progression of the disease.. Given the enormous personal, social, and economic consequences of this illness, researchers are actively seeking novel ways to slow and forestall its devastating effects.. In a randomized clinical trial, Quintana-Hernández et al. [Journal of Alzheimers Disease] compared the effectiveness of a Mindfulness-Based Alzheimers Stimulation (MBAS) program in maintaining cognitive functioning in Alzheimers patients to that of two current non-pharmacological interventions for Alzheimers disease; namely, Progressive Muscle Relaxation (PMR) and Cognitive Stimulation Therapy (CST).. The researchers ...

The natural history of Alzheimer disease: a longitudinal presymptomatic and symptomatic study of a familial cohort | IRIS...
BACKGROUND: Knowledge of the evolution of cognitive deficits in Alzheimer disease is important for our understanding of disease progression. Previous reports, however, have either lacked detail or have not covered the presymptomatic stages. OBJECTIVE: To delineate the onset and progression of clinical and neuropsychological abnormalities in familial Alzheimer disease. METHODS: Nineteen subjects with familial Alzheimer disease underwent serial clinical and neuropsychological assessments. Eight of these had undergone presymptomatic assessments. The follow-up period was 1 to 10 years (mean, 5 years). The relative timing of the occurrence of 3 markers of disease onset and progression (onset of symptoms, Mini-Mental State Examination score , or = 24, and impaired scores on a range of neuropsychological tests) were compared using the binomial exact test. RESULTS: Neurological abnormalities were not prominent, although myoclonus appeared early in some. Mini-Mental State Examination score was not ...

Allelic functional variation of serotonin transporter expression is a susceptibility factor for late onset Alzheimers disease....
We examined a deletion/insertion promoter polymorphism of the serotonin transporter gene, which confers an approximately 40% reduction in expression of the protein, in 196 subjects with late onset Alzheimers disease (AD) and 271 controls. The frequency of the 484 bp low activity allele was elevated in the subjects with AD (p = 0.004), and an excess of the low activity genotype (30%) was also found in comparison with the controls (20%) (chi 2 = 7.16; p = 0.03). This association was unrelated to the age of the subjects or controls, or to epsilon 4 alleles of the ApoE gene. The odds ratio for the effect of the homozygous low activity genotype was 1.7 (95% CI 1.08-2.67), with a population attributable risk of 33% (95% CI 5-54%). These findings indicate that the low activity allele of the serotonin transporter is a risk factor for late onset AD.

A Possible Role for CSF Turnover and Choroid Plexus in the Pathogenesis of Late Onset Alzheimers Disease - [scite report]
Supporting: 2, Contrasting: 1, Mentioning: 60 - According to the amyloid theory, the appearance of amyloid-β (Aβ) deposits represents a pivotal event in late onset Alzheimers disease (LOAD). Physiologically, Aβ42 monomers are cleaned by capillary resorption, enzymatic catabolism, and cerebrospinal fluid (CSF) transport. Factors that promote the oligomerization of Aβ42 must be specified. In vitro, these monomers spontaneously form neurotoxic oligomers whose rate increases with time suggesting that the stasis of CSF favors the oligomerization. In animals, experimental hydrocephalus generates CSF stasis followed by the appearance of amyloid deposits. In normal pressure hydrocephalus, amyloid deposits are common, especially in elderly patients, and the turnover decline has the same order of magnitude as in AD. In this disease, the effects of CSF stasis are potentiated by the decline in the ability of CSF to inhibit the formation of oligomers. CSF originates from choroid plexus (CP). In LOAD, the
4 new genes identified for Alzheimers disease risk
The second goal was for the gene discovery of the type highlighted in the Nature Genetics article to ultimately contribute to predicting who will develop Alzheimers disease, which will be important when preventive measures become available. Knowing these risk genes will also help identify the first disease-initiating steps that begin in the brain long before any symptoms of memory loss or intellectual decline are apparent. This knowledge will help researchers understand the events that lead to the destruction of large parts of the brain and eventually the complete loss of cognitive abilities. The research published in Nature Genetics was supported by the National Institute on Aging, (part of the National Institutes of Health, which includes 29 Alzheimers Disease Centers), the National Alzheimers Coordinating Center, the NIA Genetics of Alzheimers Disease Data Storage Site, the NIA Late Onset Alzheimers Disease Family Study, and the National Cell Repository for Alzheimers Disease.

Alzheimer disease - Genetics Home Reference - NIH
Some cases of early-onset Alzheimer disease are caused by gene mutations that can be passed from parent to child. This results in what is known as early-onset familial Alzheimer disease (FAD). Researchers have found that this form of the disorder can result from mutations in the APP, PSEN1, or PSEN2 genes. When any of these genes is altered, large amounts of a toxic protein fragment called amyloid beta peptide are produced in the brain. This peptide can build up in the brain to form clumps called amyloid plaques, which are characteristic of Alzheimer disease. A buildup of toxic amyloid beta peptide and amyloid plaques may lead to the death of nerve cells and the progressive signs and symptoms of this disorder. Other cases of early-onset Alzheimer disease may be associated with changes in different genes, some of which have not been identified.. Some evidence indicates that people with Down syndrome have an increased risk of developing Alzheimer disease. Down syndrome, a condition characterized ...

Localization of Genes Potentially Controlling Susceptibility to the Lethal Effects of Alzheimers Amyloid Precursor Protein in...
Variation in the susceptibility to the lethal effects of Alzheimers Amyloid Precursor Protein (APP) transgene exists among various mouse strains. Inbred FVB/N mice, expressing high levels of the transgene-encoded APP, die prior to 200 days, while inbred 129.Tg2576 mice carrying the transgene are far less susceptible. When the two strains are crossed, (FVB/Nxl29.Tg2576) FI mice survive, as does the 129.Tg2576 parent. Intercross and backcross offspring survived at rates of 60% and 35%, respectively, at 200 days signaling the presence of a polygenic trait. The goal of this study was to establish a linkage to genes affecting susceptibility to the APP transgene. The possible quantitative trait loci (QTL) were established using various genetic markers scattered throughout the genome. The presence of multiple QTLs is possible from the data obtained; however, an increased chance of type I errors (false positives) exists due to the large number of markers used for the genome scan ...
Amnestic mild cognitive impairment and early Alzheimers disease in an asian memory clinic - evidence for a clinical spectrum |...
OBJECTIVES: To determine if mild cognitive impairment (MCI) represents a continuum of cognitive and functional deficits.. METHODS: Clinical data of 164 subjects with no dementia (ND, n = 52), uncertain dementia (n = 69), and mild probable Alzheimers disease (AD, n = 43) were reviewed. Uncertain dementia patients were classified as pre-MCI (n = 11), early amnestic MCI (e-aMCI, n = 15) and late amnestic MCI (l-aMCI, n = 15). Cognitive assessments [Chinese Mini-Mental State Examination (CMMSE) and a validated neuropsychological battery], functional assessments (Lawtons scale for instrumental activities of daily living) and neuroimaging (ischemic lesions and medial temporal lobe atrophy) were reviewed.. RESULTS: ND, aMCI and mild AD subjects demonstrated a significant trend for worsening performance for all cognitive and functional measures (ANOVA, p , 0.05). Pre-MCI subjects performed significantly better than aMCI subjects in all verbal memory domains (p , 0.001), while l-aMCI had worse ...

We have developed an ultrasensitive bienzyme-substrate-recycle enzyme-linked immunosorbent assay for the measurement of Alzheimers disease (AD) abnormally hyperphosphorylated tau in cerebrospinal fluid (CSF). The assay, which recognizes attomolar amounts of tau, is approximately 400 and approximately 1300 times more sensitive than conventional enzyme-linked immunosorbent assay in determining the hyperphosphorylated tau and total tau, respectively. With this method, we measured both total tau and tau phosphorylated at Ser-396/Ser-404 in lumbar CSFs from AD and control patients. We found that the total tau was 215 +/- 77 pg/ml in cognitively normal control (n = 56), 234 +/- 92 pg/ml in non-AD neurological (n = 37), 304 +/- 126 pg/ml in vascular dementia (n = 46), and 486 +/- 168 pg/ml (n = 52) in AD patients, respectively. However, a remarkably elevated level in phosphorylated tau was only found in AD (187 +/- 84 pg/ml), as compared with normal controls (54 +/- 33 pg/ml), non-AD (63 +/- 34 pg/ml), and

The apolipoprotein E epsilon 4 allele does not influence the clinical expression of the amyloid precursor protein gene codon...
In 31 symptomatic and 5 asymptomatic carriers of the amyloid precursor protein (APP) gene codon 693 mutation, 10 family members without mutation, and 5 carriers of the APP gene codon 692 mutation (3 with early-onset Alzheimer dementia, 2 with cerebral hemorrhage), a high frequency of the apolipoprotein E epsilon 4 allele was found. Age at onset, age at death, occurrence of dementia, and number of strokes did not differ between APP gene mutation carriers with or without epsilon 4 allele, showing that the clinical expression of these APP mutations is not influenced by the apolipoprotein E gene.

Neuroprotective effects of D-Ala 2 GIP on Alzheimers disease biomarkers in an APP/PS1 mouse model | Alzheimers Research &...
Type 2 diabetes mellitus has been identified as a risk factor for Alzheimers disease (AD). An impairment of insulin signaling as well as a desensitization of its receptor has been found in AD brains. Glucose-dependent insulinotropic polypeptide (GIP) normalises insulin signaling by facilitating insulin release. GIP directly modulates neurotransmitter release, LTP formation, and protects synapses from the detrimental effects of beta-amyloid fragments on LTP formation, and cell proliferation of progenitor cells in the dentate gyrus. Here we investigate the potential therapeutic property of the new long lasting incretin hormone analogue D-Ala2GIP on key symptoms found in a mouse model of Alzheimer disease (APPswe/PS1detaE9). D-Ala2GIP was injected for 21 days at 25 nmol/kg ip once daily in APP/PS1 male mice and wild type (WT) littermates aged 6 or 12 months of age. Amyloid plaque load, inflammation biomarkers, synaptic plasticity in the brain (LTP), and memory were measured. D-Ala2GIP improved memory in

Preventing the spread of Alzheimers disease neuropathology: a role for calcilytics?
The amyloid cascade hypothesis posits that an extracellular build-up of amyloid-β oligomers (Aβ-os) and polymers (fibrils) subsequently inducing toxic hyperphosphorylated (p)-Tau oligomers (p-Tau-os) and neurofibrillary tangles starts the sporadic late-onset Alzheimers disease (LOAD) in the aged lateral entorhinal cortex. Conversely, mutated genes cause a diffuse cerebral Aβs/Aβ-os overproduction promoting early-onset familiar AD (EOFAD). Surplus exogenous Aβ-os exert toxic actions at several levels. They reach the nuclei of human astrocyte-neurons teams (ANTs) to enhance the transcription of Aβ precursor protein (APP) and β-secretase/BACE1 genes. The overexpressed APP and BACE1 proteins act in concert with γ-secretase to overproduce endogenous Aβs/Aβ-os, of which a few enter the nuclei to upkeep Aβs overproduction, while the rest gather in the cytoplasm, damage mitochondria, and are oversecreted. Simultaneously, extracellular Aβ-os bind the ANTs calcium-sensing receptors (CaSRs) ...

Hippocampal Spatial Memory Impairments Caused by the Familial Alzheimers Disease-Linked Presenilin 1 M146V Mutation - CLOK -...
Mutations in presenilins (PS) 1 and 2 are the major cause of familial Alzheimers disease. Conditional inactivation of PS1 in the mouse postnatal forebrain leads to mild deficits in spatial learning and memory, whereas inactivation of both PS1 and PS2 results in severe memory and synaptic plasticity impairments, followed by progressive and substantial neurodegeneration. Here we investigate the effect of a familial Alzheimers disease-linked PS1 missense mutation using knock-in (KI) mice, in which the wild-type PS1 allele is replaced with the M146V mutant allele. In the Morris water maze task, PS1 KI mice at 3 months of age exhibit reduced quadrant occupancy and platform crossing in the probe trial after 6 days of training, though their performance was normal in the probe trial after 12 days of training. By the age of 9 months, even after 12 days of training, PS1 homozygous KI mice still exhibit reduced platform crossing in the post-training probe trial. ELISA analysis revealed a selective ...
Prison Planet.com » Can coconut oil help Alzheimers patients?
April 23, 2013. Alzheimers disease is a neurodegenerative brain condition that comes with a multibillion-dollar per year cost to the American public, and its takeover doesnt seem to be slowing down. It is estimated that in 2013 alone, Alzheimers disease will cost Americans more than $200 billion. With its prevalence appearing to be at an all time high, it appears that the medical world and the public should be looking for better alternatives in regard to preventing its takeover. The Westernized approach to treating such a condition has some upsides, but many crucial factors seem to be left out of the overall equation - food (like coconuts) being one of these major areas to assess.. The effects of coconut oil on the brain. Coconut oil is an amazing food, and luckily, science has shown that it is among one of the most healing in nature.

The Functions of the Amyloid Precursor Protein Gene and Its Derivative Peptides: I Molecular Biology and Metabolic Processing
The amyloid precursor protein gene (APP) and its derivative peptides have important functions in the central nervous system. APP and Aβ fulfil criteria as neuractive peptides: presence, release and identity of action. Aβ is a peptide of 1 - 43 amino acids in length, derived from APP and the major component of the core of neuritic plaques found in Alzheimers disease. Analysis of the cDNA of Aβ revealed its origins from the larger precursor protein. There are at least four types of mRNA generated by alternative splicing of exons 7 and 8. Exon 7 encodes a 57 amino acid sequence found in the extracellular domain with major homology to the Kunitz-type of serine protease inhibitors. APP is cleaved by three secretases known as α, β, and γ secretase which act on APP at different sites producing various fragments of differing amino acid length. The γ secretase is a macromolecular enzyme complex composed of presenilin 1, 2 and other molecular constitutents essential for its function.
Apolipoprotein E genotype in Spanish patients of Alzheimers or Parkinsons disease. - Semantic Scholar
Blood donors of the Madrid area show a 6% frequency of apolipoprotein E genotype carrying allele epsilon 4. This frequency is smaller than other populations of Caucasian origin. This proportion decreases to 4% in a selected sample of healthy individuals of ages | 60 years. The frequency (34%) of the allele epsilon 4 was significantly increased in patients of late onset Alzheimers disease, similarly to other populations. An earlier age of onset of the dementia is observed in the patients of late-onset Alzheimers disease carrying the allele epsilon 4. No increased frequency in allele epsilon 4 frequency was found in patients of early-onset Alzheimers disease. Patients of Parkinsons disease do not show any differences in the frequency of the alleles of apolipoprotein E when compared with healthy individuals.

The medical food Souvenaid affects brain phospholipid metabolism in mild Alzheimers disease: results from a randomized...
Synaptic dysfunction contributes to cognitive impairment in Alzheimers disease and may be countered by increased intake of nutrients that target brain phospholipid metabolism. In this study, we explored whether the medical food Souvenaid affects brain phospholipid metabolism in patients with Alzheimers disease. Thirty-four drug-naive patients with mild Alzheimers disease (Mini Mental State Examination score ≥20) were enrolled in this exploratory, double-blind, randomized controlled study. Before and after 4-week intervention with Souvenaid or an isocaloric control product, phosphorus and proton magnetic resonance spectroscopy (MRS) was performed to assess surrogate measures of phospholipid synthesis and breakdown (phosphomonoesters [PME] and phosphodiesters [PDEs]), neural integrity (N-acetyl aspartate), gliosis (myo-inositol), and choline metabolism (choline-containing compounds [tCho]). The main outcome parameters were PME and PDE signal intensities and the PME/PDE ratio. MRS data from 33
Capillary cerebral amyloid angiopathy identifies a distinct APOE epsilon4-associated subtype of sporadic Alzheimers disease -...
The deposition of amyloid beta-protein (Abeta) in the vessel wall, i.e., cerebral amyloid angiopathy (CAA), is associated with Alzheimers disease (AD). Two types of CAA can be differentiated by the presence or absence of capillary Abeta-deposits. In addition, as in Alzheimers disease, risk for capillary CAA is associated with the apolipoprotein E (APOE) epsilon4-allele. Because these morphological and genetic differences between the two types of AD-related CAA exist, the question arises as to whether there exist further differences between AD cases with and without capillary CAA and, if so, whether capillary CAA can be employed to distinguish and define specific subtypes of AD. To address this question, we studied AD and control cases both with and without capillary CAA to identify the following: (1) distinguishing neuropathological features; (2) alterations in perivascular protein expression; and (3) genotype-specific associations. More widespread Abeta-plaque pathology was observed in AD ...
Two Studies in Nature on Alzheimers Disease and Vacines
AP Science Writer. December 21, 2000 (AP) -- The research was conducted by two independent research teams, centered at the University of South Florida in Tampa and the University of Toronto in Ontario, Canada. The studies used strains of mice that develop lots of amyloid plaques in their brains, along with measurable memory deficits, because of the genes they carry. The researchers used different versions of a procedure in which mice swam until they learned the location of an underwater platform. The animals were then tested to see how well they remembered where the platform was. Alzheimers patients frequently have trouble remembering locations and how to get to destinations.. Both studies found that mice that had been repeatedly vaccinated performed markedly better than the untreated plaque-forming mice in the memory tests. On some occasions they did as well or nearly as well as ordinary mice. University of South Florida researcher Dave Morgan said his vaccinated mice were slower to learn the ...

Reduction in Mitochondrial Superoxide Dismutase Modulates Alzheimers Disease-Like Pathology and Accelerates the Onset of...
Most common neurodegenerative disorders likely result from complex interactions between genetic and environmental risk factors (Farrer et al., 1997; Munoz and Feldman, 2000; Lindsay et al., 2002). One such factor may be aging-related alterations in the redox state of mitochondria (Hirai et al., 2001; Eckert et al., 2003; Beal, 2005) Our study shows that partial reduction in the main mitochondrial superoxide scavenger Sod2 accelerates the onset of hAPP/Aβ-dependent behavioral abnormalities and worsens a range of AD-related molecular and pathological alterations.. How might Sod2 reduction modulate the phenotype of hAPP mice or AD? An obvious mechanism is increased mitochondrial levels of superoxide radicals and resultant oxidative damage. To assess this possibility, we measured mitochondrial aconitase activity, a well-established mitochondrial sensor of superoxide that is lower in the heart and liver of adult Sod2+/− mice than in Sod2+/+ controls (Williams et al., 1998; Van Remmen et al., ...
Rubidium and potassium levels are altered in Alzheimers disease brain and blood but not in cerebrospinal fluid | Acta...
Loss of intracellular compartmentalization of potassium is a biochemical feature of Alzheimers disease indicating a loss of membrane integrity and mitochondrial dysfunction. We examined potassium and rubidium (a biological proxy for potassium) in brain tissue, blood fractions and cerebrospinal fluid from Alzheimers disease and healthy control subjects to investigate the diagnostic potential of these two metal ions. We found that both potassium and rubidium levels were significantly decreased across all intracellular compartments in the Alzheimers disease brain. Serum from over 1000 participants in the Australian Imaging, Biomarkers and Lifestyle Flagship Study of Ageing (AIBL), showed minor changes according to disease state. Potassium and rubidium levels in erythrocytes and cerebrospinal fluid were not significantly different according to disease state, and rubidium was slightly decreased in Alzheimers disease patients compared to healthy controls. Our data provides evidence that contrasts the
Coexisting pathologies in the brain: influence of vascular disease and Parkinsons disease on Alzheimers pathology in the...
The finding of more than one coexisting brain pathology in dementia sufferers is not unusual. However, it is unclear how these different diseases may interact or influence the evolution of one another. In this study we analyse the hippocampal expression patterns of hyperphosphorylated tau, paired helical filament (PHF)-related protein, beta-amyloid and synaptophysin in a group of Alzheimers disease (AD) sufferers with and without additional pathology. Compared to cases with only AD-type pathology we found that the presence of additional vascular disease augmented the accumulation of hyperphosphorylated tau in the CA1 region of the hippocampus without affecting PHF formation in cases with mild AD changes and reduced the extent of PHF formation in the CA2/3 and CA4 regions of the hippocampus in cases with severe AD pathology. We also found that synaptophysin immunoreactivity in the CA4 and dentate gyrus in pure AD was inversely related to the extent of amyloid accumulation but not to neurofibrillary

The Importance of Cannabis For Alzheimers Patients | Themocracy
In a 2014 scientific study, researchers have discovered strong evidence of the therapeutic effects of THC found in cannabis, in regards to reversing the brain damage associated with Alzheimers Disease. The results clearly are in favor of low-dose, monitored use of cannabis to lower the levels of amyloid-beta precursor proteins, characteristic of this health problem.. Amyloid-beta precursor proteins are large membrane proteins that support neural health, growth, and repair. Due to the natural aging process and the presence of inflammation, a corrupted version of these proteins may begin to produce, destroying neurons and consequently, the memories, thinking process, and even the personality of the Alzheimers patient.. If THC successfully lowers the level of the corrupted amyloid-beta precursor proteins, does this mean that Alzheimers Disease can be completely reversed? Scientists do not yet have clear-cut and straightforward answers to this important question. Even though the political and ...

Brain perfusion follow-up in Alzheimers patients during treatment with acetylcholinesterase inhibitors. - Oxford Neuroscience
UNLABELLED: Transient cognitive and behavioral stabilization of patients with Alzheimers disease (AD) is the main goal of long-term acetylcholinesterase inhibitor (AChEI) therapy, but response to treatment is variable and, indeed, only some of the patients are stabilized. This is usually assessed by means of clinical and neuropsychologic scales, whereas functional neuroimaging could allow objective evaluation of the topographic correlates of the effect of therapy on brain functioning. The aim of this study was to evaluate brain perfusion changes by SPECT in AD patients during chronic AChEI therapy in relation to their cognitive evolution. METHODS: Forty-seven consecutive outpatients with mild-to-moderate probable AD (as defined by the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimers Disease and Related Disorders Association and the Diagnostic and Statistical Manual of Mental Disorders [4th edition criteria] and a score of | or =15 on the Mini-Mental State
Amyloid Cascade Hypothesis
The amyloid cascade hypothesis postulates that the initial event which triggers neuronal degradation in Alzheimers disease is enhanced amyloid-β generation and aggregation.

Occupational Therapy Proves Effective in Treating Alzheimers Disease - Brain and Spinal Cord
For the past three decades, research has linked traumatic brain injury with an increased risk of developing Alzheimers disease later in life. According to the Alzheimers Association, research shows that the way traumatic brain injury changes brain chemistry indicates a relationship between traumatic brain injury and hallmark protein abnormalities linked to Alzheimers. Many medications are on the market to treat the condition, but research has shown that occupational therapy can help improve the symptoms of Alzheimers disease as well.. According to HealthDay, many practitioners say occupational therapy can help keep Alzheimers patients safe at home. Occupational therapy consists of a therapist helping a patient, and the patients family, develop treatment plans that help the patient improve with daily activities and occupations. As stated by the The American Occupational Therapy Association, the primary aims of occupational therapy are nhancing function, promoting relationships and social ...
Hyperspectral Raman imaging of neuritic plaques and neurofibrillary tangles in brain tissue from Alzheimers disease patients. ...
Neuritic plaques and neurofibrillary tangles are crucial morphological criteria for the definite diagnosis of Alzheimers disease. We evaluated 12 unstained frontal cortex and hippocampus samples from 3 brain donors with Alzheimers disease and 1 control with hyperspectral Raman microscopy on samples of 30 × 30 µm. Data matrices of 64 × 64 pixels were used to quantify different tissue components including proteins, lipids, water and beta-sheets for imaging at 0.47 µm spatial resolution. Hierarchical cluster analysis was performed to visualize regions with high Raman spectral similarities. The Raman images of proteins, lipids, water and beta-sheets matched with classical brain morphology. Protein content was 2.0 times, the beta-sheet content 5.6 times and Raman broad-band autofluorescence was 2.4 times higher inside the plaques and tangles than in the surrounding tissue. The lipid content was practically equal inside and outside. Broad-band autofluorescence showed some correlation with ...
Early-Onset Alzheimers Disease: Know the Facts
Up to five percent of people diagnosed with Alzheimers are in their forties and fifties when it strikes. Known as early-onset Alzheimers, this middle-aged disease affects about 200,000 people in the U.S. alone.
First Responders and Alzheimers Disease
By Alan Fleming People with Alzheimers disease or other dementias pose a unique challenge to first responders. An emergency situation can create an emotionally catastrophic reaction in a person with Alzheimers. Whether they are the person that needs help or a bystander on the scene, people with Alzheimers require special attention. Because they thrive best in a calm and familiar environment, they have considerable difficulty when their routine is disrupted. The Alzheimers Association, West Virginia Chapter offers an interactive training module for first responders, specially created to help them handle emergencies where people with Alzheimers disease or other dementias are present.. The inherent degenerative nature of Alzheimers disease creates a variety of communications challenges. Every person with Alzheimers is different. The disease progresses through different stages with each person exhibiting an array of symptoms and behaviors specific to Alzheimers. How a person with Alzheimers ...
Alzheimers Disease May Be More Prevalent And Manifests Itself Differently Among African Americans - Healthcanal.com :...
The older African American population is growing at a rapid pace, and the burden of aging-related cognitive impairment and Alzheimers disease will continue to present a tremendous challenge, said Lisa Barnes, PhD. This study highlights the importance of research among minority groups within the communities in which hospitals serve. Barnes is the primary author and director of the Rush Center of Excellence on Disparities in HIV and Aging in the Rush Alzheimers Disease Center, and professor of Neurological Sciences and Behavioral Sciences at Rush University Medical Center. The lack of high-quality biologic data on large numbers of racial and ethnic minorities poses barriers to progress in understanding whether the mechanisms and processes of Alzheimers disease operate the same or differently in racial and ethnic minorities and, if so, how, particularly in the high-risk African American population, said Barnes. In 2010, the U.S. Census Bureau indicated that 20 percent of the population ages ...
