What is dementia?

People who have dementia have a problem in the brain that makes it hard for them to remember, learn and communicate. These changes eventually make it hard for them to care for themselves. Dementia may also cause changes in mood and personality. Early on, lapses in memory and clear thinking may bother the person with dementia. Later, disruptive behavior and other problems can create a burden for caregivers and other family members.

Dementia is caused by the damage of brain cells. A head injury, stroke, brain tumor or disease (such as Alzheimer's disease) can damage brain cells.
