-
Frontotemporal Dementia: This type of dementia is caused by damage to the lobes at the front and/or sides of the brain. It is much more common in younger people with dementia than in older people. FTD is most often diagnosed in people between the ages of 45 and 65.
-
Younger Onset Dementia: This term is used to describe any form of dementia that develops in people under the age of 65. Dementia has been diagnosed in people in their 50s, 40s, and even younger.
