Abstract The clinical conceptual change in frontal type dementia is reviewed in discussing its relationships to several related concepts such as Pick's disease, frontotemporal dementia (FTD), semantic dementia (SD) and frontotemporal lobar degeneration (FTLD).
We analyzed cases of FTLD selected from a consecutive series of our outpatients as to the details of neuropsychological symptoms, psychiatric symptoms, and abnormal behaviors. In our series of 124 patients with primary degenerative dementia, there were 14 cases of frontotemporal dementia and 4 cases of SD. Patients with FTD and patients with SD were not distinguishable by neuropsycological examinations, behavioral abnormalities and psychiatric symptoms assessed with the Neuropsychiatric Inventory except for aphasia.
At this point, FTLD is a plausible, comprehensive, clinical conception of frontal type dementia. However, we will have to examine whether each clinical syndrome of FTLD will be able to be established as a disease entity from the viewpoint of clinical, neuropathological, and molecular aspects.
Keywords dementia, nosology, Pick's disease, Fronto-Temporal Dementia, Fronto-Temporal Lobar Degeneration
