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).
A single-pass type I membrane protein. It is cleaved by AMYLOID PRECURSOR PROTEIN SECRETASES to produce peptides of varying amino acid lengths. A 39-42 amino acid peptide, AMYLOID BETA-PEPTIDES is a principal component of the extracellular amyloid in SENILE PLAQUES.
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.

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.  (+info)

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 ...

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 ...
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 ...
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 ...

AU - Mulla, M.. PY - 2000/8/7. Y1 - 2000/8/7. N2 - We investigated the occurrence of a Cystatin C genetic variant in 312 Caucasian clinic-based Alzheimers Disease (AD) cases versus 136 age-matched population-based Caucasian controls (age/age of onset range 60-91yrs). 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 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.. ...
The cognitive profile of Alzheimer patients without (AD E-, n=17) and with (AD, E+, n=15) extrapyramidal signs (rigidity or bradykinesia), at the time of diagnosis, was examined in a 3-year follow-up
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 ...
The Alzheimers Disease Research Center (ADRC) at the Icahn School of Medicine at Mount Sinai is a comprehensive research facility and clinical program dedicated to the study and treatment of normal aging and Alzheimers disease.
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 ...
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.. ...

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 ...
In this study, we have evaluated the levels of blood histamine, serum interleukin-1 beta (IL-1 beta), and plasma tumor necrosis factor-alpha (TNF-alpha) in 20 patients with mild to moderate Alzheimer disease (AD; 13 early onset and 7 late-onset AD subjects) and in 20 age-matched control subjects (C) …

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 ...

A bit of peanut butter and a ruler may be an easy way confirm a diagnosis of early-stage Alzheimers disease, U.S. researchers say.
Brussels, Belgium, 19 July 2017 - Today, the Innovative Medicines Initiative (IMI) is launching two new Calls for proposals with topics on Alzheimers disease, big data, vaccines, autoimmune disease, the blood-brain barrier, drug development, and the exploitation of IMI project results. The total budget for the two Calls stands at just over EUR 130 million. Around half of this comes from the European Commissions Horizon 2020 programme. The other half comes from EFPIA companies as well as IMI Associated Partners.
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 ...

PY - 2004/3/9. Y1 - 2004/3/9. N2 - Whether elevated β-secretase (BACE) activity is related to plaque formation or amyloid β peptide (Aβ) production in Alzheimers disease (AD) brains remains inconclusive. 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 ...

Cox proportional hazard models were used for each cohort to estimate the hazard ratio (HR) and 95% confidence interval (CI) of the lifestyle score with ...
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

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 ...
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 ...
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 ...
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
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 ...

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 ...

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.

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
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. These ...
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 ...

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 ...
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 ...
Background and Purpose: We sought to assess the efficacy and safety of donepezil in patients with vascular dementia (VaD) fulfilling National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et lEnseignement en Neurosciences criteria.; Methods: This international, multicenter, 24-week trial was conducted from March 2003 to August 2005. Patients (N=974; mean age, 73.0 years) with probable or possible VaD were randomized 2:1 to receive donepezil 5 mg/d or placebo. Coprimary outcome measures were scores on the Vascular-Alzheimer Disease Assessment Scale-Cognitive Subscale and Clinicians Interview-Based Impression of Change, plus carer interview. Analyses were performed for the intent-to-treat population with the last-observation-carried-forward method.; Results: Compared with placebo, donepezil-treated patients showed significant improvement from baseline to end point on the Vascular-Alzheimer Disease Assessment Scale-Cognitive Subscale (least-squares ...
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

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.
July 14, 2010 /Press Release/ -- Researchers at Mount Sinai School of Medicine have used a newly discovered class of biomarkers to investigate the possibility that the shape of brain protein deposits is different in people with Alzheimers who have the highest-risk gene type than in those with the condition who have a neutral risk gene type.

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
BACKGROUND/AIMS: Memantine has been approved by the Food and Drug Administration for the treatment of moderate-to-severe Alzheimers disease (AD). However, the effect of memantine on patients with mild-to-moderate AD is unclear. METHODS: This study is a post hoc analysis of a double-blind clinical trial. Donepezil was used as the standard control treatment. Outcomes included score changes from baseline to week 24 on the Alzheimers Disease Assessment Scale-Cognitive Subscale (ADAS-cog), a modified 20-item Activities of Daily Living Scale (ADL), the Neuropsychiatric Inventory (NPI), and the Mini-Mental State Examination (MMSE) as well as the score of the Clinicians Interview-Based Impression of Change plus Caregiver Input (CIBIC-Plus ...
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) ...

We demonstrate that this conjugated nanoparticle binds to CVA deposits in arterioles of AD transgenic mice (Tg2576) after infusion into the external carotid ...
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 ...
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. In regard to helping Alzheimers patients, the ketone bodies, which are given off when coconut oils fatty acids are metabolized by the liver, can be a perfect ...

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.
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.
Study: Ginkgo Improves Lives of Alzheimers Patients & Caregivers Brought to you from the NEEDS Wellness Team A recent published study evaluated the effects of the herb, Ginkgo biloba, on a total of nearly 400 Alzheimers and/or dementia patients. Half of the study group took 120 mg of Ginkgo and the other half took a placebo--both twice daily for 22 weeks. The researchers then measured the patients cognitive state, daily functioning, and severity of neuro-psychiatric symptoms using various testing methods. There was significant improvement in cognitive skills in patients taking the ginkgo, where those taking the placebo experienced cognitive decline. Sixty-one percent of the ginkgo users improved their level of daily living activities (i.e., hygiene, household chores) as compared to an improvement in only 15% of the patients in the placebo group. A larger number of patients in the ginkgo group also experienced a decrease in neuropsychiatric symptoms, including apathy,
Scientists from the Monell Center and the US Department of Agriculture (USDA) alongside other research organizations have been able to differentiate a distinctive odor unique to the urine of Alzheimers patients. The research was however conducted on lab mice models.. Get the Free Tracker App to find a SNES Classic in Stock. The odor signature in the urine of the mice models indicate that potential patients can be diagnosed through the urine odor signature before the manifestation of cognitive symptoms, enabling researchers to develop non-invasive tools for early diagnosis of the disease.. Previous research from the USDA and Monell has focused on body odor changes due to exogenous sources such as viruses or vaccines. Now we have evidence that urinary odor signatures can be altered by changes in the brain characteristic of Alzheimers disease, said study author Bruce Kimball, a chemical ecologist with the USDA National Wildlife Research Center (NWRC) who is stationed at the Monell Center. This ...

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
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 ...
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 ...
Disease-modifying treatments in MS are one of the most rapidly evolving areas of therapeutic intervention in neurology. As new treatments become available, the options for patients, and their prescribing physicians, increases. Many of the newer therapies have complex risk: benefit profiles and require specialized expertise for safe and effective administration. Faculty will focus on therapeutic strategies and risk mitigation of currently available disease-modifying therapies, discuss proper use of these drugs and risk assessment, and use specific examples to cover the most frequent issues arising from MS treatment strategies. This program complements C54: Multiple Sclerosis Therapy: Disease-modifying Treatment II and C116: Multiple Sclerosis Therapy: Symptom Management, but covers independent topics ...
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., ...
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
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

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 ...

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

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 ...
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 ...
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.
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 ...
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 ...
