Alzheimer Disease
Alzheimer disease is a disease that affects the brain and nervous system. It is a type of dementia that happens when nerve cells in the brain die.
Early-Onset Alzheimer Disease
Alzheimer disease most commonly affects older adults, but it can also affect people in their 30s or 40s. When Alzheimer disease occurs in someone under age 65, it is known as early-onset (or younger-onset) Alzheimer disease.
Stages of Alzheimer Disease
Alzheimer disease is a brain disorder that causes memory loss, confusion, and changes in personality. It is a type of dementia.
Caring for Someone with Alzheimer Disease

Dementia with Lewy bodies (DLB) is a form of progressive dementia caused by degeneration of the tissues in the brain.
Frontotemporal Dementia
Frontotemporal dementia (FTD), a common cause of dementia, is a group of disorders that occur when nerve cells in the frontal and temporal lobes of the brain are lost. This causes the lobes to shrink. FTD can affect behavior, personality, language, and movement.
Vascular Dementia
Vascular dementia is caused by decreased blood flow to brain tissue causing signs of dementia.
