Definition
By Mayo Clinic staffDementia isn't a specific disease. Instead, dementia describes a group of symptoms affecting intellectual and social abilities severely enough to interfere with daily functioning. Many causes of dementia symptoms exist. Alzheimer's disease is the most common cause of a progressive dementia.
Memory loss generally occurs in dementia, but memory loss alone doesn't mean you have dementia. Dementia indicates problems with at least two brain functions, such as memory loss and impaired judgment or language. Dementia can make you confused and unable to remember people and names. You also may experience changes in personality and social behavior. However, some causes of dementia are treatable and even reversible.
