Alzheimer disease is a neurodegenerative disorder marked by cognitive and behavioral impairment that significantly interferes with social and occupational functioning. It is an incurable disease with a long preclinical period and progressive course. Plaques develop in the hippocampus, a structure deep in the brain that helps to encode memories, and in other areas of the cerebral cortex that are involved in thinking and decision-making. Whether plaques themselves cause Alzheimer disease or whether they are a by-product of the Alzheimer disease process remains unknown.

Alzheimer disease is the sixth leading cause of death in the United States, accounting for 4.2% of all deaths in 2016—a 3.1% increase from 2015.

Currently, an autopsy or brain biopsy is the only way to definitively diagnose Alzheimer disease. The diagnosis is usually made on the basis of the history and findings on the mental status examination. Symptomatic therapies are the only treatments available for Alzheimer disease.
