Alzheimer's disease (AD) is the most common cause of dementia in the elderly. It is characterized by a progressive loss of memory, reasoning, judgment, and orientation, by the presence of large numbers of extracellular senile plaques and intracellular neurofibrillary tangles, as well as substantial cell loss in the brain. Genetic studies in early onset families have identified mutations in three genes that cause AD, while genetic studies in sporadic AD have identified the apolipoprotein E4 allele as a risk factor for disease. In vitro cell biology and transgenic mouse studies implicate all of these genes in the biology of Aβ metabolism. A consistent effect of these genetic factors is an increase in Aβ deposition. Furthermore, cell biology studies have identified targets for possible treatment of AD. Transgenic models are now being used to test the validity of these targets and therapeutic approaches to the treatment of AD.
