The most common severe disabilities of the elderly is the impairment of cognitive and memory processes that occur in Alzheimer's disease (AD). The principal histopathologic hallmarks of AD are the formation of neurofibrillary tangles involving specific populations of neurons and the extracellular deposition of the β-amyloid (Aβ) in the parenchyma and around the cerebral blood vessels. This review briefly describes the abnormalities of neurons and examines in detail the biology of the amyloid precursor protein and Aβ as studied in vitro and in vivo in animal models.
