Frontotemporal dementia is a rare disorder that affects the front (frontal lobes) and the sides (temporal lobes) of the brain. Because these regions often, but not always, shrink, brain imaging can be useful in diagnosis.
There is no specific abnormality associated with all cases of frontotemporal dementia. In one type called Pick’s disease, there are abnormal microscopic deposits called Pick bodies, but these are not always present.
