Major depression was more common and severe in patients with vascular dementia than in patients with AD. In another study of 288 outpatients with dementia, a prevalence of 7.4% was found with HAM-D, 8% prevalence with the GDS and 6.3% with DSM-IV criteria (Brodaty and Luscombe, 1996).
Dementia is a loss of brain function that occurs with certain diseases. It affects memory, thinking, language, judgment, and behavior. Dementia usually occurs in older age. It is rare in people under age 60. The risk of dementia increases as a person gets older. Most types of dementia are nonreversible (degenerative). Nonreversible means the changes in the brain that are causing the dementia cannot be stopped or turned back. Alzheimer disease is the most common type of dementia. Another common type of dementia is vascular dementia. It is caused by many small strokes. Lewy body disease is a common cause of dementia in the elderly. People with this condition have abnormal protein structures in certain areas of the brain.
