Alzheimer's disease—A disease that causes large numbers of nerve cells in the brain to die. This makes it hard for a person to remember things, think clearly, and make good judgments. The symptoms begin slowly and get worse over time.
Mild cognitive impairment—Also called MCI. It causes people to have more memory problems than other people their age. The signs of MCI are not as severe as those of Alzheimer's disease. They include losing things often, forgetting to go to events and appointments, and having more trouble coming up with the right words than other people their age. MCI may be an early sign of Alzheimer's.
Vascular dementia—A medical condition caused by small strokes or changes in the brain's blood supply. Signs can appear suddenly. They include changes in memory, language, thinking skills, and mood.
