Definition
By Mayo Clinic staffAlzheimer's disease is a progressive disease that destroys memory and other important mental functions.
It's the most common cause of dementia — a group of brain disorders that results in the loss of intellectual and social skills. These changes are severe enough to interfere with day-to-day life.
In Alzheimer's disease, the connections between brain cells and the brain cells themselves degenerate and die, causing a steady decline in memory and mental function.
Current Alzheimer's disease medications and management strategies may temporarily improve symptoms. This can sometimes help people with Alzheimer's disease maximize function and maintain independence.
But because there's no cure for Alzheimer's disease, it's important to seek supportive services and tap into your support network as early as possible.
