Abstract

Alzheimer's Disease (AD) is a progressive neurodegenerative disorder marked by loss of memory, cognition, and behavioral stability. AD is defined pathologically by extracellular neuritic plaques comprised of fibrillar deposits of beta-amyloid peptide (Abeta) and neurofibrillary tangles comprised of paired helical filaments of hyperphosphorylated tau. Current therapies for AD, such as cholinesterase inhibitors, treat the symptoms but do not modify the progression of the disease. The etiology of AD is unclear. However, data from familial AD mutations (FAD) strongly support the "amyloid cascade hypothesis" of AD, i.e. that neurodegeneration in AD is initiated by the formation of neurotoxic beta-amyloid (Abeta) aggregates; all FAD mutations increase levels of Abeta peptide or density of Abeta deposits. The likely link between Abeta aggregation and AD pathology emphasizes the need for a better understanding of the mechanisms of Abeta production. This review summarizes current therapeutic strategies directed at lowering Abeta levels and decreasing levels of toxic Abeta aggregates through (1) inhibition of the processing of amyloid precursor protein (APP) to Abeta peptide, (2) inhibition, reversal or clearance of Abeta aggregation, (3) cholesterol reduction and (4) Abeta immunization.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
