FTD is a form of dementia, or altered mental status, which is distinct from the cognitive and memory problems evident in Alzheimer’s disease.
FTD involves a change in personality that can produce obsessive behavior, loss of the ability to plan or make decisions, and other more subtle signs that something is amiss in the cerebral cortex.
Frontotemporal refers to the forward part of the brain that sits above the eyes and behind the temples. It is the last region of the cerebral cortex to mature, which explains why teens often cannot make good “adult” decisions. Lowering of the function of this region can lead to impulsive and emotional behavior.
