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)
Cerebral Amyloid Angiopathy, Familial
A familial disorder marked by AMYLOID deposits in the walls of small and medium sized blood vessels of CEREBRAL CORTEX and MENINGES.
Amyloid beta-Peptides
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.
Amyloid
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.
Cerebral Hemorrhage
Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.
Plaque, Amyloid
Accumulations of extracellularly deposited AMYLOID FIBRILS within tissues.
Alzheimer Disease
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)
Amyloidosis
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.
Brain
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.
Vasculitis, Central Nervous System
Inflammation of blood vessels within the central nervous system. Primary vasculitis is usually caused by autoimmune or idiopathic factors, while secondary vasculitis is caused by existing disease process. Clinical manifestations are highly variable but include HEADACHE; SEIZURES; behavioral alterations; INTRACRANIAL HEMORRHAGES; TRANSIENT ISCHEMIC ATTACK; and BRAIN INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, pp856-61)
Amyloid beta-Protein Precursor
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.
Cerebral Arteries
The arterial blood vessels supplying the CEREBRUM.
Congo Red
An acid dye used in testing for hydrochloric acid in gastric contents. It is also used histologically to test for AMYLOIDOSIS.

Siderosis
A form of pneumoconiosis resulting from inhalation of iron in the mining dust or welding fumes.
Intracranial Hemorrhages
Bleeding within the SKULL, including hemorrhages in the brain and the three membranes of MENINGES. The escape of blood often leads to the formation of HEMATOMA in the cranial epidural, subdural, and subarachnoid spaces.
Apolipoprotein E4
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.
Neurofibrillary Tangles
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.
Presenilin-1
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.
Cerebral Arterial Diseases
Pathological conditions of intracranial ARTERIES supplying the CEREBRUM. These diseases often are due to abnormalities or pathological processes in the ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; and POSTERIOR CEREBRAL ARTERY.
Apolipoproteins E
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.
Meninges

A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (ARTERIES or VEINS) in the CEREBRUM, the CEREBELLUM, and the BRAIN STEM. Major categories include INTRACRANIAL ARTERIOVENOUS MALFORMATIONS; BRAIN ISCHEMIA; CEREBRAL HEMORRHAGE; and others.
Magnetic Resonance Imaging
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
Dementia
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.
Autopsy
Postmortem examination of the body.
Dementia, Vascular
An imprecise term referring to dementia associated with CEREBROVASCULAR DISORDERS, including CEREBRAL INFARCTION (single or multiple), and conditions associated with chronic BRAIN ISCHEMIA. Diffuse, cortical, and subcortical subtypes have been described. (From Gerontol Geriatr 1998 Feb;31(1):36-44)
Alkenes
Unsaturated hydrocarbons of the type Cn-H2n, indicated by the suffix -ene. (Grant & Hackh's Chemical Dictionary, 5th ed, p408)
Apolipoprotein E2
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.

Intracellular accumulation of the amyloidogenic L68Q variant of human cystatin C in NIH/3T3 cells. (1/260)

AIM: To study the cellular transport of L68Q cystatin C, the cystatin variant causing amyloidosis and brain haemorrhage in patients suffering from hereditary cystatin C amyloid angiopathy (HCCAA). METHODS: Expression vectors for wild-type and L68Q cystatin C were constructed and used to transfect mouse NIH/3T3 cells. Stable cell clones were isolated after cotransfection with pSV2neo. Clones expressing human wild-type and L68Q cystatin C were compared with respect to secreted cystatin C by enzyme linked immunosorbent assay (ELISA), and for intracellular cystatin C by western blotting and immunofluorescence cytochemistry. Colocalisation studies in cells were performed by double staining with antibodies against human cystatin C and marker proteins for lysosomes, the Golgi apparatus, or the endoplasmic reticulum, and evaluated by confocal microscopy. RESULTS: Concentrations of human cystatin C secreted from transfected NIH/3T3 cells were similar to those secreted from human cells in culture. In general, clones expressing the gene encoding L68Q cystatin C secreted slightly lower amounts of the protein than clones expressing wild-type human cystatin C. Both immunofluorescence cytochemistry and western blotting experiments showed an increased accumulation of cystatin C in cells expressing the gene encoding L68Q cystatin C compared with cells expressing the gene for the wild-type protein. The intracellularly accumulating L68Q cystatin C was insoluble and located mainly in the endoplasmic reticulum. CONCLUSIONS: The cellular transport of human cystatin C is impeded by the pathogenic amino acid substitution Leu68-->Gln. The resulting intracellular accumulation and increased localised concentration of L68Q cystatin C might be an important event in the molecular pathophysiology of amyloid formation and brain haemorrhage in patients with HCCAA.  (+info)

Histopathologic analysis of foci of signal loss on gradient-echo T2*-weighted MR images in patients with spontaneous intracerebral hemorrhage: evidence of microangiopathy-related microbleeds. (2/260)

BACKGROUND AND PURPOSE: Patients with spontaneous intracerebral hemorrhage (ICH) frequently have small areas of signal loss on gradient-echo T2*-weighted MR images, which have been suggested to represent remnants of previous microbleeds. Our aim was to provide histopathologic support for this assumption and to clarify whether the presence and location of microbleeds were associated with microangiopathy. METHODS: We performed MR imaging and correlative histopathologic examination in 11 formalin-fixed brains of patients who had died of an ICH (age range, 45-90 years). RESULTS: Focal areas of signal loss on MR images were noted in seven brains. They were seen in a corticosubcortical location in six brains, in the basal ganglia/thalami in five, and infratentorially in three specimens. Histopathologic examination showed focal hemosiderin deposition in 21 of 34 areas of MR signal loss. No other corresponding abnormalities were found; however, hemosiderin deposits were noted without MR signal changes in two brains. All specimens with MR foci of signal loss showed moderate to severe fibrohyalinosis, and there was additional evidence of amyloid angiopathy in two of those brains. CONCLUSION: Small areas of signal loss on gradient echo T2*-weighted images indicate previous extravasation of blood and are related to bleeding-prone microangiopathy of different origins.  (+info)

Cerebral amyloid angiopathy-related hemorrhage. Interaction of APOE epsilon2 with putative clinical risk factors. (3/260)

BACKGROUND AND PURPOSE: Current evidence suggests that the apolipoprotein E (APOE for gene; apoE for protein) epsilon4 allele predisposes to cerebral amyloid angiopathy (CAA) whereas epsilon2 is associated with CAA-related hemorrhage (CAAH). The clinical risk factors for other forms of intracranial hemorrhage are a less-frequent feature of CAAH. In this study we examined potential clinical risk factors in patients with CAAH and assessed these with respect to APOE genotype. METHODS: Thirty-six patients were identified with a pathological diagnosis of CAAH. Clinical notes were reviewed to document age of hemorrhage onset, history of dementia, antiplatelet/anticoagulant medication, hypertension, minor head trauma, or transient neurological events. In a review of reported cases of CAAH, the frequency of these clinical features was also recorded. APOE genotypes were determined with use of polymerase chain reaction techniques. RESULTS: There were 24 women and 12 men; the mean age was 70.3 years. One third (n=12) had been taking antiplatelet medication, and a similar number were demented. Nine patients were hypertensive, and 4 had a history of recent minor head trauma. The relative frequency of each of these clinical features was similar to that in previous reports. Forty-four percent (16 of 36) possessed an epsilon2 allele. Antiplatelet or anticoagulant medication, hypertension, or minor head trauma were significantly more frequent antecedents of CAAH in epsilon2 carriers than in non-epsilon2 carriers (81% versus 35%, P=0.008), antiplatelet/anticoagulant medication in particular (P=0.038). CONCLUSIONS: Our findings suggest that antiplatelet or anticoagulant medication, hypertension, or minor head trauma are most likely to precipitate cerebral hemorrhage in patients with CAA who are also epsilon2 carriers. This may result from isoform-specific effects of apoE on the structure of amyloid-laden blood vessel walls.  (+info)

Soluble amyloid beta peptide concentration as a predictor of synaptic change in Alzheimer's disease. (4/260)

We have characterized amyloid beta peptide (Abeta) concentration, Abeta deposition, paired helical filament formation, cerebrovascular amyloid angiopathy, apolipoprotein E (ApoE) allotype, and synaptophysin concentration in entorhinal cortex and superior frontal gyrus of normal elderly control (ND) patients, Alzheimer's disease (AD) patients, and high pathology control (HPC) patients who meet pathological criteria for AD but show no synapse loss or overt antemortem symptoms of dementia. The measures of Abeta deposition, Abeta-immunoreactive plaques with and without cores, thioflavin histofluorescent plaques, and concentrations of insoluble Abeta, failed to distinguish HPC from AD patients and were poor correlates of synaptic change. By contrast, concentrations of soluble Abeta clearly distinguished HPC from AD patients and were a strong inverse correlate of synapse loss. Further investigation revealed that Abeta40, whether in soluble or insoluble form, was a particularly useful measure for classifying ND, HPC, and AD patients compared with Abeta42. Abeta40 is known to be elevated in cerebrovascular amyloid deposits, and Abeta40 (but not Abeta42) levels, cerebrovascular amyloid angiopathy, and ApoE4 allele frequency were all highly correlated with each other. Although paired helical filaments in the form of neurofibrillary tangles or a penumbra of neurites surrounding amyloid cores also distinguished HPC from AD patients, they were less robust predictors of synapse change compared with soluble Abeta, particularly soluble Abeta40. Previous experiments attempting to relate Abeta deposition to the neurodegeneration that underlies AD dementia may have failed because they assayed the classical, visible forms of the molecule, insoluble neuropil plaques, rather than the soluble, unseen forms of the molecule.  (+info)

A deletion polymorphism of alpha(2)-macroglobulin gene and cerebral amyloid angiopathy. (5/260)

BACKGROUND AND PURPOSE: alpha(2)-Macroglobulin may be implicated in amyloid beta protein deposition. A deletion in the exon 18 splice acceptor of the alpha(2)-macroglobulin gene (A2M) has been reported to be associated with risk for Alzheimer's disease (AD). In search of genetic risk factors for cerebral amyloid angiopathy (CAA), we investigated association of the A2M deletion polymorphism with CAA. METHODS: The association between the severity of CAA and A2M deletion polymorphism was investigated in 178 autopsy cases of the elderly including 68 patients with AD. RESULTS: There was no significant difference in the severity of CAA between individuals with the A2M deletion allele and those without in the AD, non-AD, or total cases. Status for the epsilon4 allele of the apolipoprotein E gene did not influence the results. CONCLUSIONS: Our results suggest that the A2M deletion polymorphism may not be a definitive risk factor of CAA in the elderly, although further study with larger samples is necessary to confirm this.  (+info)

Neuronal overexpression of mutant amyloid precursor protein results in prominent deposition of cerebrovascular amyloid. (6/260)

Transgenic mice that overexpress mutant human amyloid precursor protein (APP) exhibit one hallmark of Alzheimer's disease pathology, namely the extracellular deposition of amyloid plaques. Here, we describe significant deposition of amyloid beta (Abeta) in the cerebral vasculature [cerebral amyloid angiopathy (CAA)] in aging APP23 mice that had striking similarities to that observed in human aging and Alzheimer's disease. Amyloid deposition occurred preferentially in arterioles and capillaries and within individual vessels showed a wide heterogeneity (ranging from a thin ring of amyloid in the vessel wall to large plaque-like extrusions into the neuropil). CAA was associated with local neuron loss, synaptic abnormalities, microglial activation, and microhemorrhage. Although several factors may contribute to CAA in humans, the neuronal origin of transgenic APP, high levels of Abeta in cerebrospinal fluid, and regional localization of CAA in APP23 mice suggest transport and drainage pathways rather than local production or blood uptake of Abeta as a primary mechanism underlying cerebrovascular amyloid formation. APP23 mice on an App-null background developed a similar degree of both plaques and CAA, providing further evidence that a neuronal source of APP/Abeta is sufficient to induce cerebrovascular amyloid and associated neurodegeneration.  (+info)

Novel presenilin-1 mutation with widespread cortical amyloid deposition but limited cerebral amyloid angiopathy. (7/260)

OBJECTIVE: To clarify the phenotypic heterogeneity in deposition of amyloid beta (Abeta) in the parenchyma and in cerebral vessels of the brains of the patients having presenilin-1 (PS1) mutations. Mutations in PS1 induce increased production of Abeta42(43), resulting in an enhanced overall deposition of Abeta protein within the cerebral cortex. METHODS: Sequence analysis of the PS1 gene of DNA from patients with early onset Alzheimer's disease, and immunostaining of brain tissues by end specific monoclonal antibodies against Abeta. RESULTS: Sequence analysis disclosed a novel mutation (N405S) in the PS1 gene in a Japanese patient with early-onset Alzheimer's disease. Postmortem examination of one patient with N405S showed limited cerebral amyloid angiopathy, whereas postmortem examination of another Japanese patient with Alzheimer's disease with the E184D mutation disclosed severe cerebral amyloid angiopathy. The brains of both patients showed widespread neuritic plaques, neurofibrillary tangles, and neuronal loss. Immunostaining showed that Abeta42 was predominant over Abeta40 in neuritic plaques in both patients, whereas Abeta40 was found to be predominant over Abeta42 in cerebral amyloid angiopathy in the patient with E184D. However, most cortical vessels of the patient with N405S were not reactive with either of the antibodies. CONCLUSION: The N405S mutation of PS1 is a major determinant of cortical Abeta deposition but not cerebral amyloid angiopathy in Alzheimer's disease.  (+info)

Apolipoprotein E genotype and the risk of recurrent lobar intracerebral hemorrhage. (8/260)

BACKGROUND: Recurrent lobar intracerebral hemorrhage is the hallmark of cerebral amyloid angiopathy. The factors that predispose patients to early recurrence of lobar hemorrhage are unknown. One candidate is the apolipoprotein E gene, since both the epsilon2 and the epsilon4 alleles of apolipoprotein E appear to be associated with the severity of amyloid angiopathy. METHODS: We performed a prospective, longitudinal study of consecutive elderly patients who survived a lobar intracerebral hemorrhage. The patients were followed for recurrent hemorrhagic stroke by interviews at six-month intervals and reviews of medical records and computed tomographic scans. RESULTS: Nineteen of 71 enrolled patients had recurrent hemorrhages during a mean follow-up period of 23.9+/-14.8 months, yielding a 2-year cumulative rate of recurrence of 21 percent. The apolipoprotein E genotype was significantly associated with the risk of recurrence. Carriers of the epsilon2 or epsilon4 allele had a two-year rate of recurrence of 28 percent, as compared with only 10 percent for patients with the common apolipoprotein E epsilon3/epsilon3 genotype (risk ratio, 3.8; 95 percent confidence interval, 1.2 to 11.6; P=0.01). Early recurrence occurred in eight patients, four of whom had the uncommon epsilon2/epsilon4 genotype. Also at increased risk for recurrence were patients with a history of hemorrhagic stroke before entry into the study (two-year recurrence, 61 percent; risk ratio, 6.4; 95 percent confidence interval, 2.2 to 18.5; P<0.001). CONCLUSIONS: The apolipoprotein E genotype can identify patients with lobar intracerebral hemorrhage who are at highest risk for early recurrence. This finding makes possible both the provision of prognostic information to patients with lobar hemorrhage and a method of targeting and assessing potential strategies for prevention.  (+info)

Intracerebral hemorrhage is common in persons with this condition, but pure subarachnoid or subdural hemorrhage is rarely seen. Recently, the existence of two types of amyloid proteins related to cerebral amyloid angiopathy, ß protein and cystatin C, has been reported, and Immunohis-tochemical methods using antisera to these proteins have become available. We describe a patient with fatal subarachnoid hemorrhage presumably caused by ß protein-type cerebral amyloid angiopathy, which was demonstrated immunohistochemicaliy by using a monoclonal antibody to a synthetic peptide corresponding to ...

Lateralized Cerebral Amyloid Angiopathy presenting with recurrent Lacunar Ischemic StrokeLateralized Cerebral Amyloid Angiopathy presenting with recurrent Lacunar Ischemic Stroke
Cerebral amyloid angiopathy (CAA) is characterized by the deposition of fibrillar protein with beta-pleated sheet configuration in the media and adventitia of small cortical and leptomeningeal arteries and capillaries [2]. Previous studies based on autopsy observation revealed that the risk of CAA increased with age, which was around 38% between 80-89 years reached up to 42% in patient above the age of 90 [3]. CAA encompasses specific cerebrovascular traits including spontaneous lobar intracerebral hemorrhage (ICH), cognitive impairment, subarachnoid hemorrhage, and transient focal neurological episodes, with characteristic imaging manifestation of lobar ICH, cortical superficial siderosis, white matter changes, microhemorrhage and microinfarct.. Interestingly in our case report, the microbleeds were strictly lateralized and predominantly in the MCA supplied territory, rather than in a diffused pattern. It has been acknowledged that the CAA could have certain localization preference. One ...

A 56-year-old man noticed discomfort in his left lower limb, followed by convulsion and numbness in the same area. Magnetic resonance imaging (MRI) showed white matter lesions in the right parietal lobe accompanied by leptomeningeal or leptomeningeal and cortical post-contrast enhancement along the parietal sulci. The patient also exhibited higher brain dysfunction corresponding with the lesions on MRI. Histological pathology disclosed β-amyloid in the blood vessels and perivascular inflammation, which highlights the diagnosis of cerebral amyloid angiopathy (CAA)-related inflammation. Pulse steroid therapy was so effective that clinical and radiological findings immediately improved. CAA-related inflammation is a rare disease, defined by the deposition of amyloid proteins within the leptomeningeal and cortical arteries associated with vasculitis or perivasculitis. Here we report a patient with CAA-related inflammation who showed higher brain dysfunction that improved with steroid therapy. In cases with

Cerebral amyloid angiopathy is estimated to be responsible for ≈5% to 20% of nontraumatic intracerebral hemorrhages and 30% of lobar hemorrhages.3 Whereas CAA may be asymptomatic, a classic clinical presentation is lobar hemorrhage, often recurrent or multifocal, in an elderly individual. Less commonly, patients may present with TIA or other ischemic stroke-like episodes, seizures, or dementia involving a spectrum of cognitive decline.4. In the past decade, neuroimaging studies, particularly MRI, have played an increasingly important role in the diagnosis and understanding of the pathophysiology of CAA.5 Specifically, gradient-recalled echo sequences have documented the occurrence, frequency, and distribution of microbleeds. Multiple lobar microbleeds, particularly in the absence of deep microbleeds and an alternative cause (eg, hypertension, CADASIL), are now considered a radiological hallmark of CAA.1. An additional MRI technique, diffusion-weighted imaging, has offered the ability to ...

Cerebral amyloid angiopathy with multiple intracerebral hemorrhages. Case report | Meta
Cerebral amyloid angiopathy (CAA) has been associated with atypical dementia and a variety of other neurological disorders. Intracerebral hemorrhage is the most striking manifestation of CAA. A 63-year-old patient is described who sustained four intracerebral hemorrhages although he had no predisposing factors other than CAA. The neurological and pathological features of CAA are reviewed, with particular emphasis on the problem of CAA-associated intracerebral hemorrhage. On the basis of the experience with this case, it is recommended that adjacent brain parenchyma be biopsied in all patients undergoing evacuation of intracerebral hematomas of unclear etiology. ...

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 ...

Cerebral amyloid angiopathy (CAA) is a small-vessel disorder associated with progressive amyloid deposition in the walls of cortical and leptomeningeal vessels. Sporadic forms are more common than inherited familial forms.. CAA is a major cause of lobar symptomatic intracerebral haemorrhage, transient focal neurologic episodes in the elderly, and cognitive impairment. Transient focal neurological episodes include both positive migraine aura-like (spreading paraesthesias and/or positive visual phenomena) and negative TIA-like neurological symptoms, and may be caused by superficial cortical siderosis or convexal subarachnoid haemorrhage. These episodes are associated with a high early risk of symptomatic intracerebral haemorrhage. ...

Matrix metalloproteinase-9 and spontaneous hemorrhage in an animal model of cerebral amyloid angiopathy. - Science ExchangeMatrix metalloproteinase-9 and spontaneous hemorrhage in an animal model of cerebral amyloid angiopathy. - Science Exchange
We examined the potential role of the extra-cellular matrix-degrading enzyme, matrix metalloproteinase-9 (MMP-9), in the pathogenesis of cerebral amyloid angiopathy (CAA)-induced spontaneous hemorrhage. The amyloid-beta peptide (Abeta) induced the synthesis, release and activation of MMP-9 in murine cerebral endothelial cells, resulting in increased extracellular matrix degradation. Furthermore, extensive MMP-9 immunoreactivity was observed in CAA-vessels with evidence of microhemorrhage in aged APPsw transgenic mice, but not detected in aged wild type or young APPsw mice. These results suggest that increased vascular MMP-9 expression, stimulated by Abeta, may play a role in the pathogenesis of spontaneous intracerebral hemorrhage in patients with CAA.. ...

Amyloid is deposited in the walls of arteries and capillaries as cerebral amyloid angiopathy (CAA) in the brains of older individuals and of those with Alzheimer disease (AD). CAA in AD reflects an age-related failure of elimination of amyloid-beta (A?) from the brain along perivascular lymphatic drainage pathways. In the absence of conventional lymphatic vessel in the brain, interstitial fluid and solutes drain from the brain to cervical lymph nodes along narrow basement membranes in the walls of capillaries and arteries, a pathway that is largely separate from the cerebrospinal fluid. In this review we focus on the pathology and pathogenesis of CAA, its role in the aetiology of AD and its impact on immunotherapy for AD. The motive force for lymphatic drainage of the brain appears to be generated by arterial pulsations. Failure of elimination of A? along perivascular pathways coincides with a reduction in enzymic degradation of A?, reduced absorption of A? into the blood and age-related ...

Cerebral Amyloid Angiopathy: Emerging ConceptsCerebral Amyloid Angiopathy: Emerging Concepts
CAA is not necessarily associated with CAA-related disorders. The pathogenesis of CAA-related disorders consists of two steps: (1) cerebrovascular amyloid deposition and (2) vascular injury including disruption, occlusion, and permeability changes. The cerebrovascular amyloid deposition (Step 1) is the primary target of prevention and therapy. Anti-amyloid therapies for CAA are under development including ponezumab, a humanized monoclonal antibody that binds specifically to the carboxyl terminus of Aβ40.115 Ponezumab was originally developed for AD immunotherapy, and an acceptable safety profile has been suggested for ponezumab in clinical trials for AD.116,117,118 Currently, ponezumab has been applied to CAA. A phase 2, randomized, double-blind, placebo-controlled trial is ongoing to evaluate the safety, tolerability, pharmacokinetics, and efficacy of ponezumab (PF-04360365) in adult patients with probable CAA-related hemorrhages (NCT01821118).119.

age-related macular degeneration Genetics Home Reference provides information about age-related macular degeneration. hereditary cerebral amyloid angiopathy At least one mutation in the CST3 gene has been found to cause hereditary cerebral amyloid angiopathy, a condition characterized by stroke and a decline in intellectual function (dementia), which begins in mid-adulthood. The CST3 gene mutation that has been identified causes a form of hereditary cerebral amyloid angiopathy known as the Icelandic type. This mutation replaces the protein building block (amino acid) leucine with the amino acid glutamine at position 68 in the cystatin C protein (written as Leu68Gln or L68Q). This abnormal cystatin C protein is less stable and is more prone to cluster together (aggregate) than the normal protein. The aggregated protein forms clumps called amyloid deposits that accumulate in the blood vessel walls primarily in the brain, but also in blood vessels in other areas of the body such as the skin, ...

N2 - Cerebral amyloid angiopathy (CAA) is frequently observed in Alzheimers disease (AD) and is characterized by deposition of amyloid beta (Aβ) in leptomeningeal and cortical brain vasculature. In 40% of AD cases, Aβ mainly accumulates in cortical capillaries, a phenomenon referred to as capillary CAA (capCAA). The aim of this study was to investigate blood-brain barrier (BBB) alterations in CAA-affected capillaries with the emphasis on tight junction (TJ) changes. First, capCAA brain tissue was analyzed for the distribution of TJs.

Tissue Microstructural Changes Are Independently Associated With Cognitive Impairment in Cerebral Amyloid Angiopathy | StrokeTissue Microstructural Changes Are Independently Associated With Cognitive Impairment in Cerebral Amyloid Angiopathy | Stroke
The major finding from this cohort study of patients with possible or probable CAA is that, among MRI markers of CAA, global mean ADC (reflecting microstructural tissue organization) is most strongly related to the presence of pre-ICH cognitive impairment. The association of mean ADC with PICI was independent of age, clinical variables, amount of visible cerebral atrophy, and other MRI markers. By contrast, we failed to detect a relationship between PICI and WMH volume, number of MB, or visible cerebral atrophy.. Decreased cognitive performance has previously been associated with CAA. The prevalence of cognitive dysfunction before CAA-related ICH is reported to be 20% to 40%4,5,17,30 Autopsy-based studies of stroke-free individuals show that CAA is a risk factor for decreased antemortem cognitive performance while simultaneously controlling for the pathology of Alzheimer disease.31,32 This suggests that the association between CAA and cognitive dysfunction is not entirely mediated by concomitant ...

p,A hemi-paralyzed 86-year-old man was diagnosed with ischemic stroke and underwent thrombolysis. Pre-thrombolysis brain magnetic resonance imaging revealed extensive strictly lobar cerebral microbleeding (CMB). Post-thrombolytic computed tomography revealed asymptomatic multiple intracerebral hemorrhaging (ICH). His age, CMB topography, and decreased cerebral spinal fluid amyloid-β 40 and 42 levels were compatible with a diagnosis of cerebral amyloid angiopathy (CAA). There is no consensus on the safety of thrombolysis for acute stroke patients with CAA. Patients with CAA might have a higher incidence of thrombolysis-related ICH than those without CAA. ,/p,. ...

Blood Oxygen Level Dependant (BOLD) fMRI was performed at Screening (Baseline) and on Days 2 and 90. During each of these sessions, BOLD fMRI images were acquired in rapid succession as a flashing radial black and white checkerboard was presented alternately with a gray screen. This well established visual stimulus is known to produce a reliable increase in BOLD fMRI signal within the visual cortex region of the occipital lobe. The time course of the BOLD fMRI signal was used to assess the vascular reactivity. Imaging sites also acquired cerebral blood flow data using Arterial Spin Labeled (ASL) scans at Screening and on Days 2 and 90. A standard T1-weighted image was also acquired to aid image analysis. All efficacy scans were analyzed centrally. Geometric means are presented in the original scale and standard errors (SE) are presented in logarithmic (log e) scale ...

Deposition of beta-amyloid along cerebral vessels is found in most patients suffering from Alzheimers disease. The effects of cerebral amyloid angiopathy (CAA) on the function of cerebral blood vessels were analyzed applying cerebral blood volume (CBV)-based fMRI to transgenic arcA beta mice. In a cortical brain region of interest (ROI), displaying high CAA, arcA beta mice older than 16 months showed reduced response to the vasodilatory substance acetazolamide compared to age-matched wild-type animals, both with regard to rate (vascular reactivity) and extent of vasodilation (maximal vasodilation). In a subcortical ROI, displaying little CAA, no genotype-specific decrease was observed, but maximal vasodilation decreased with age in arcA beta and wild-types. These findings indicate that vascular beta-amyloid deposits reduce the capacity of cerebral blood vessels to dilate upon demand, supporting the hypothesis that vascular beta-amyloid contributes to hypoperfusion and neurological deficits ...

The article by Pfeifer et al. describes the exacerbation of cerebral hemorrhages seen in an aged APP-transgenic model following passive administration of anti-Aβ antibodies directed to amino acids 3-6. This particular transgenic mouse, called APP23, is described by the authors in a previous paper as a spontaneous hemorrhagic stroke mouse model (Winkler et al., 2001). At approximately 19 months of age onward, the mouse exhibits severe cerebral amyloid angiopathy (CAA), which is associated with recurrent hemorrhages as the mice age. Moderate to severe cerebral vascular amyloid also exists in approximately 26 percent of Alzheimers disease patients, as well, though the rate of hemorrhages is less than that seen in the APP23 mouse (approximately five percent of AD cases; see Greenberg et al., 1998).. When the authors gave 21-month-old APP23 mice a monoclonal antibody directed to Aβ3-6 once a week for five months, they saw that the rate of hemorrhages increased about twofold above baseline.

The accumulation of amyloid-β (Aβ) peptides as toxic oligomers, amyloid plaques, and cerebral amyloid angiopathy (CAA) is critical in the pathogenesis of Alzheimers disease (AD). The binding of Aβ peptides to apolipoprotein E (ApoE) plays an important role in modulation of amyloid deposition and clearance. We have shown that blocking the Aβ/ApoE interaction with Aβ12-28P, a nontoxic blood-brain-barrier permeable and non-fibrillogenic synthetic peptide, constitutes a novel therapeutic approach for AD by reducing Aβ parenchymal deposition. In the present study, we investigate this therapeutic effect on CAA in the transgenic (Tg) AD mice model (TgSwDI), which expresses Swedish (K670N/M671L), Dutch (E693Q)/Iowa (D694N) Aβ PP mutations. These mice develop abundant CAA beginning at the age of 6 months. Behavioral results show that Aβ12-28P treated TgSwDI AD mice performed the same as wild-type mice, whereas vehicle treated TgSwDI were impaired in spatial memory. Furthermore, this treatment resulted

Alzheimers disease (AD) is a progressive neurodegenerative disease that has emerged as the most prevalent form of late-life dementia in humans [1]. Production of amyloid-β (Aβ) from the amyloid precursor protein (APP) and its subsequent accumulation, aggregation and deposition in the brain are central events in the pathogenesis of AD [1]. Cerebral amyloid angiopathy (CAA) is a major pathological feature of AD where amyloid spreads and deposits throughout the blood vessel walls in the central nervous system. These pathogenic events induce a specific clinical presentation profile including cerebral hemorrhage, stroke, ischemic infarctions, subarachnoid hemorrhage, seizures, cognitive impairment and dementia [2]. While Aβ is a key molecule in AD, epidemiological studies have shown that several well-established risk factors for AD, including diabetes mellitus, atherosclerosis, stroke, hypertension, transient ischemic attacks, microvessel pathology and smoking, have a vascular component that ...

Basement membranes in the walls of cerebral capillaries and arteries form a major lymphatic drainage pathway for fluid and solutes from the brain. Amyloid-β (Aβ) draining from the brain is deposited in such perivascular pathways as cerebral amyloid angiopathy (CAA) in Alzheimers disease (AD). CAA increases in severity when Aβ is removed from the brain parenchyma by immunotherapy for AD. In this study we investigated the consequences of immune complexes in artery walls upon drainage of solutes similar to soluble Aβ. We tested the hypothesis that, following active immunization with ovalbumin, immune complexes form within the walls of cerebral arteries and impair the perivascular drainage of solutes from the brain. Mice were immunized against ovalbumin and then challenged by intracerebral microinjection of ovalbumin. Perivascular drainage of solutes was quantified following intracerebral microinjection of soluble fluorescent 3kDa dextran into the brain at different time intervals after intracerebral

Neuropathological follow-up of patients with Alzheimers disease (AD) who participated in the first clinical trial of Amyloid-β 42 (Aβ42) immunization (AN1792, Elan Pharmaceuticals) has shown that immunization can induce removal of Aβ42 and Aβ40 from plaques, whereas analysis of the cerebral vessels has shown increased levels of these Aβ peptides in cerebral amyloid angiopathy (CAA). Aβ43 has been less frequently studied in AD, but its aggregation propensity and neurotoxic properties suggest it may have an important pathogenic role. In the current study we show by using immunohistochemistry that in unimmunized AD patients Aβ43 is a frequent constituent of plaques (6.0% immunostained area), similar to Aβ42 (3.9% immunostained area). Aβ43 immunostained area was significantly higher than that of Aβ40 (2.3%, p = 0.006). In addition, we show that Aβ43 is only a minor component of CAA in both parenchymal vessels (1.5 Aβ43-positive vessels per cm2 cortex vs. 5.3 Aβ42-positive vessels, p = 0.03,

ALZFORUM | NETWORKING FOR A CUREALZFORUM | NETWORKING FOR A CURE
The studies by Meyer-Luehman et al. extend insights into the in vivo formation of amyloid deposits by amyloid seeds that may be hetero- and/or homo-amyloidogenic inducers of amyloid fibrillization. This is significant because these types of studies will lead to the clarification of the perplexing conundrum of why there is a frequent co-occurrence of multiple different types of amyloids in neurodegenerative disorders characterized by brain amyloidosis. Indeed, double and triple neurodegenerative brain amyloidoses appear to far exceed in incidence and prevalence any neurodegenerative brain amyloidosis linked to a single amyloidogenic protein or peptide, and this enigma demands clarification if we are to develop more effective therapies for these disorders.. For example, with respect to Aβ deposits, these may occur by themselves as pathological signatures of single brain amyloidoses, such as cerebral amyloid angiopathy (CAA), which most commonly manifests clinically as stroke.

LRP1 in brain vascular smooth muscle cells mediates local clearance of Alzheimers amyloid-beta.LRP1 in brain vascular smooth muscle cells mediates local clearance of Alzheimers amyloid-beta.
Kanekiyo T., Liu C.C., Shinohara M., Li J., Bu G.. Impaired clearance of amyloid-β (Aβ) is a major pathogenic event for Alzheimers disease (AD). Aβ depositions in brain parenchyma as senile plaques and along cerebrovasculature as cerebral amyloid angiopathy (CAA) are hallmarks of AD. A major pathway that mediates brain Aβ clearance is the cerebrovascular system where Aβ is eliminated through the blood-brain barrier (BBB) and/or degraded by cerebrovascular cells along the interstitial fluid drainage pathway. An Aβ clearance receptor, the low-density lipoprotein receptor-related protein 1 (LRP1), is abundantly expressed in cerebrovasculature, in particular in vascular smooth muscle cells. Previous studies have indicated a role of LRP1 in endothelial cells in transcytosing Aβ out of the brain across the BBB; however, whether this represents a significant pathway for brain Aβ clearance remains controversial. Here, we demonstrate that Aβ can be cleared locally in the cerebrovasculature by ...

Role of P-Glycoprotein in Alzheimers Disease for Enhanced Brain Elimi by Hope HoltRole of P-Glycoprotein in Alzheimers Disease for Enhanced Brain Elimi by Hope Holt
Alzheimers disease (AD), the most common form of neurodegenerative disorder, is characterized by deposition of amyloid-β (Aβ) plaques in the brain. Aβ monomer undergoes nucleation to form oligomers, then soluble aggregates, then fibrils which make up the plaques. Aβ oligomer species are believed to be the most neurotoxic aggregate species. Currently under investigation is a mechanism for Aβ removal from the brain, across the blood-brain barrier (BBB). P-glycoprotein (P-gp) is a membrane-bound efflux protein located on the apical, or blood, side of the BBB, which transports a wide variety of substrates. Further complicating this potential clearance mechanism is the reduction of P-gp cell surface expression in arteries exhibiting cerebral amyloid angiopathy (CAA), or the buildup of amyloid plaques around the arteries. P-gp has been suggested as a potential Aβ clearance mechanism based on its ability to transport a wide variety of amphipathic substrates even though experimental evidence of Aβ

Self-assembly of the amyloid-β (Aβ) peptide into aggregates, from small oligomers to amyloid fibrils, is fundamentally linked with Alzheimers disease (AD). However, it is clear that not all forms of Aβ are equally harmful and that linking a specific aggregate to toxicity also depends on the assays and model systems used (Haass et al., J Biol. Chem 269:17741-17748, 1994; Borchelt et al., Neuron 17:1005-1013, 1996). Though a central postulate of the amyloid cascade hypothesis, there remain many gaps in our understanding regarding the links between Aβ deposition and neurodegeneration. In this study, we examined familial mutations of Aβ that increase aggregation and oligomerization, E22G and ΔE22, and induce cerebral amyloid angiopathy, E22Q and D23N. We also investigated synthetic mutations that stabilize dimerization, S26C, and a phospho-mimetic, S8E, and non-phospho-mimetic, S8A. To that end, we utilized BRI2-Aβ fusion technology and rAAV2/1-based somatic brain transgenesis in mice to selectively

Spontaneous intracerebral hemorrhage (ICH), defined as nontraumatic bleeding into the brain parenchyma, is the second most common subtype of stroke, with 5.3 million cases and over 3 million deaths reported worldwide in 2010. Case fatality is extremely high (reaching approximately 60 % at 1 year post event). Only 20 % of patients who survive are independent within 6 months. Factors such as chronic hypertension, cerebral amyloid angiopathy, and anticoagulation are commonly associated with ICH. Chronic arterial hypertension represents the major risk factor for bleeding ...

Cortical superficial siderosis and intracerebral hemorrhage risk in cerebral amyloid angiopathyCortical superficial siderosis and intracerebral hemorrhage risk in cerebral amyloid angiopathy
Our findings indicate that cSS, particularly if disseminated, is associated with an increased risk of symptomatic lobar ICH in CAA. cSS may help stratify future bleeding risk in CAA, with implications for prognosis and treatment.

Clinical Trials Registry | Internet Stroke Center
Non-traumatic cortical superficial siderosis (cSS) is a common finding in patients with cerebral amyloid angiopathy (CAA) and can be its sole imaging sign. The clinical features and course as well as the prognostic significance of cSS in CAA patients remain unclear. In a retrospective study we have previously shown that cSS might be an important predictor or warning sign for future intracranial hemorrhage. However, prospective data are missing. The Superficial Siderosis in Patients with suspected Cerebral Amyloid Angiopathy (SuSPect-CAA) study is designed as a prospective observational multi-centre cohort study. Primary objective of the study is to evaluate if cSS is a predictor for future stroke and mortality (primary endpoint: combined rate of stroke and death after 36 months). Secondary objectives of the study include 1) to evaluate if cSS represents a marker of future intracranial haemorrhage, especially at the site of initial siderosis, 2) to describe the clinical presentation and course of ...

The acceptability of presymptomatic testing in 21 people at 50% risk for the APP-692 mutation causing presenile Alzheimers disease or cerebral haemorrhage resulting from cerebral amyloid angiopathy (FAD-CH), and in 43 people at 50% risk for hereditary Pick disease (HPD) was assessed. Neither group differed in demographic variables. Thirty-nine people (64%) in the whole group would request presymptomatic testing if it were clinically available, although two-thirds did not yet feel ready to take it. The most important reasons in the HPD and FAD-CH group for taking the test were: to further basic research (42% and 47%, respectively), informing children (47% and 50%, respectively), future planning (29% and 47%, respectively), and relieving uncertainty (46% and 27%, respectively). The most commonly cited effect of an unfavourable test result concerned increasing problems for spouses (75% and 76%, respectively) and children (61% and 57%, respectively).

ITM2B gene - Genetics Home Reference - NIHITM2B gene - Genetics Home Reference - NIH
Two mutations in the ITM2B gene have been found to cause a condition called hereditary cerebral amyloid angiopathy. When this condition is caused by mutations in the ITM2B gene, it is characterized by movement problems and a decline in intellectual function (dementia). ITM2B gene mutations cause two forms of the condition called familial British dementia and familial Danish dementia, named for the regions where the conditions were first diagnosed. The ITM2B gene mutation that causes the British type results in the production of a protein that is longer than normal. The ITM2B protein normally has a stop signal that indicates where to stop the protein sequence so that all the ITM2B proteins that are made are the same. The mutation that causes the British type changes the stop signal so that more length is added to the protein. This mutation is written as Ter267Arg or X267R. The mutation that causes the Danish type is similar, but instead of changing the stop signal, extra pieces of DNA are added ...

We evaluated cerebrospinal fluid amyloid-β 1-40 (Aβ40), amyloid-β 1-42 (Aβ42), total and phosphorylated-tau (t-tau and p-tau) in patients with symptomatic isolated cortical supratentorial superficial siderosis (SS), by prospectively recruiting ten patients with SS in the absence of pre-existing cognitive dysfunction, and comparing biomarkers with lobar hematoma cerebral amyloid angiopathy patients (LH-CAA, n = 13), Alzheimers disease patients (AD, n = 42), and controls (n = 16). Compared to controls, SS patients showed statistically significant higher t-tau (p = 0.019) and lower Aβ42 (p = 0.0084). Compared to other groups, SS showed statistically significant lower t-tau, p-tau, and Aβ40 compared to AD (p = 0.0063, p = 0.0004, and p = 0022, respectively), and higher p-tau compared to LH-CAA (p = 0.012).

BACKGROUND Cortical superficial siderosis (CSS) is a neuroimaging marker of cerebral amyloid angiopathy and has been associated with a high risk for early subsequent major intracranial hemorrhage (ICH). Therefore, many experts recommend withholding of antithrombotic medication to patients with CSS. In this study, we sought to investigate the prevalence of CSS and the associated risk of ICH in the setting of intravenous thrombolysis (IVT) for ischemic stroke. METHODS We retrospectively searched the medical documentation system of our primary and tertiary care university clinic for all patients with ischemic stroke that received IVT from 2009 to December 2014. All available imaging data were reviewed in a standardized manner and blinded to any clinical data for the presence of CSS and ICH. CSS was defined as linear signal loss along the cerebral cortex on gradient echo T2*-weighted sequences. A stroke neurologist, who was blinded to the neuroimaging data, extracted the corresponding clinical data

Tau lesions also were found in the forms of NFT and clusters of tau-positive neurites (for example, pieces of dying neurons). NFT are observed in AD patients, but the tau-immunoreactive neuritic clusters in the neocortex appear specific to chimpanzees, said Dr. Patrick R. Hof, M.D., the Regenstreif professor and vice-chair of neuroscience at Icahn School of Medicine at Mount Sinai. In addition, NFT pathology was observed in apes that exhibited plaques and moderate or severe cerebral amyloid angiopathy and in one individual with virtually no Aβ pathology.. The presence of amyloid and tau pathology in aged chimpanzees indicates these AD lesions are not specific to the human brain as generally believed, Hof said. Whether these pathologies play a key role in age-related cognitive decline requires continued investigation of this species, said Dr. Elliott Mufson, professor and the Greening Chair in Aging at the Barrow Neurological Institute..

BestBets: Safety of Radiation for Brain tumors in pre-existing Alzheimers disease.BestBets: Safety of Radiation for Brain tumors in pre-existing Alzheimers disease.
Alzheimers disease (AD) neural structures may have the inability to cope up with natural radiation [Momcilović B et al]. There exist DNA repair defects in familial AD, but not in sporadic AD [Boerrigter ME et al.]. Cranial radiation is a risk factor for A-β amyloid deposition and amyloid angiopathy in Brain. Radiation injures endothelial cells, breaks the blood-brain barrier and could be an enhancing factor of A-β deposition, although further study is necessary [Sugihara S et al.]. Changes typical of AD such as the formation of neuritic or diffuse plaques and tangles were not identified as a consequence of cranial irradiation. Although the neurodegenerative changes of radiation therapy are different from that of AD [Riudavets et al.], both have similar effect on cognitive function of neuronal structures [Shaw EG et al.]. Further studies with larger case sample that includes longer post-treatment intervals are needed to improve the understanding of the consequences and mechanisms leading to ...

One in 85 persons worldwide will be living with Alzheimers disease (AD), according to forecasts by Johns Hopkins University. To date, there is no cure for AD. Current FDA-approved therapies are symptomatic treatments that only modestly improve cognitive functions and do not stop the progression of the disease.. Stemedica Internationals unique, disease-modifying treatment combines itMSCs, itNSCs and related stem cell factors to improve the quality of life for AD patients. The company has conducted extensive pre-clinical studies to assess the technologys safety and efficacy on amyloid pathology and brain function in preparation for clinical applications in patients with mild to moderate AD. The data strongly supports that Stemedica Internationals therapy safely removes cerebral amyloid plaques, bringing new hope to patients and families affected by the condition. Pre-clinical data also supports the therapys potential application for patients with mild cognitive impairment (MCI).. Stemedica ...

CAA has been identified as an independent risk factor for cognitive impairment and is associated with significant pathologies such as hemorrhage and ischemic damage (Greenberg et al., 2004). In typical cases, progressive CAA leads to the destruction of smooth muscle cells in the meningeal and parenchymal vasculature, presumably leading to tonal impairment and compromise of both perfusion and perivascular clearance systems (Christie et al., 2001; Preston et al., 2003). Currently Aβ-targeted therapeutic approaches for AD have not been shown to reduce vascular amyloid deposition in chronic in vivo preclinical paradigms. However, there is evidence that the direct application of amyloid antibodies to the brain (Prada et al., 2007) and blocking the apolipoprotein E/Aβ interaction (Sadowski et al., 2006) reduce VAβ.. We show here evidence of the near-complete prevention and/or clearance of VAβ by an N-terminal-specific Aβ antibody (3D6) after chronic treatment with a peripherally administered ...
