Beta amyloid immunoreactivity is probably due to a significant number of Ab catabolites corresponding to N-terminally truncated and Cterminally truncated or extended forms which display distinct propensity to aggregation. Very few things are known concerning the mechanisms and proteases by which they are generated. Furthermore, the link between truncation and toxicity has not been delineated.
Finally, little is known concerning Ab fragments in biological fluids and whether they could be seen as early biomarkers and thereby, as putative targets for AD diagnostic. The present project will allow to examine the human biological samples and to identify various cohorts after complete clinical evaluation.

The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation.
Currently, no cures or disease modifying therapies exist for Alzheimer's disease (AD). This is partially due to the inability to detect the disease before it has progressed to a stage wher...
Participants enrolled in the Alzheimer's Disease Clinical Core at Wake Forest School of Medicine will be invited to take part in this study. The purpose of this study is to identify and me...
This study will evaluate the performance of Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) in patients with Alzheimer's disease (AD).
ALADDIN is a research study to investigate the safety and effectiveness of leuprolide (a hormone drug) to improve the cognitive function and slow the progression of Alzheimer's disease (AD...
Neuroimaging modalities can measure different aspects of the disease process in Alzheimer's disease, although the relationship between these modalities is unclear.
The new National Institute on Aging and the Alzheimer's Association Research Framework for Alzheimer's disease has been developed to accelerate drug discovery and offer a common structure and language...
Exploring the role of Alzheimer's disease (AD) implicated pathways in the predementia phase may provide new insight for preventive and clinical trials targeting disease specific pathways.
Sex effects on the progression of Alzheimer's disease (AD) have received less attention than other demographic factors, including onset age and education.
Magnetic resonance imaging (MRI) acquisition/processing techniques assess brain volumes to explore neurodegeneration in Alzheimer's disease (AD).
Abnormal structures located chiefly in distal dendrites and, along with NEUROFIBRILLARY TANGLES and SENILE PLAQUES, constitute the three morphological hallmarks of ALZHEIMER DISEASE. Neuropil threads are made up of straight and paired helical filaments which consist of abnormally phosphorylated microtubule-associated tau proteins. It has been suggested that the threads have a major role in the cognitive impairment seen in Alzheimer disease.
Vaccines or candidate vaccines used to prevent or treat ALZHEIMER DISEASE.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.

A carbamate-derived reversible CHOLINESTERASE INHIBITOR that is selective for the CENTRAL NERVOUS SYSTEM and is used for the treatment of DEMENTIA in ALZHEIMER DISEASE and PARKINSON DISEASE.
A biochemical phenomenon in which misfolded proteins aggregate either intra- or extracellularly. Triggered by factors such as MUTATION, POST-TRANSLATIONAL MODIFICATIONS, and environmental stress, it is generally associated with ALZHEIMER DISEASE; PARKINSON DISEASE; HUNTINGTON DISEASE; and TYPE 2 DIABETES MELLITUS.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
