What is Dementia?

Dementia is not a specific disease, but rather a syndrome caused by one or more disorders that affect the brain.

Memory loss is the most common symptom, but people also can experience problems with language, have difficulty solving problems, undergo personality and behavior changes, and struggle with activities of daily living, such as dressing and feeding oneself. About 90% of dementia cases are caused by Alzheimer's disease, vascular dementia, or some combination of the two.
