What FRONTOTEMPORAL DEMENTIA - (FRONTOTEMPORAL LOBAR DEGENERATION) means: Frontotemporal Dementia - (frontotemporal lobar degeneration) is an umbrella term for a diverse group of rare disorders that primarily affect the frontal and temporal lobes of the brain - the areas generally associated with personality and behavior. It differs from other causes of dementia such as Alzheimer's, Pick's and Creutzfeldt Jakob's diseases. Behavioral symptoms include apathy and aspontaneity or oppositely disinhibition. Apathetic patients may become socially withdrawn and stay in bed all day or no longer take care of themselves. Disinhibited patients can make inappropriate (sometimes sexual) comments or perform inappropriate acts.
