What is mixed dementia?

Judith London, MD
Psychiatrist (Therapist)

Mixed dementia can be any combination of more than one dementia occurring at the same time. Dementia caused by Alzheimer's disease is the most common form of dementia, followed by vascular dementia, Lewy body dementia, front temporal dementia, or a dementia associated with head injury, neurological illness, or other ailments. When any two dementias co-exist, the diagnosis is mixed dementia.

Mixed dementia occurs when vascular dementia and Alzheimer's disease develop at the same time. In these cases, a person will show signs of cardiovascular disease and Alzheimer's disease. Vascular dementia also can appear on its own and has some symptoms, such as memory loss and confusion, similar to Alzheimer's symptoms.
