Dementias can be calssified into cortical, subcortical, cortical-subcortical and multifocal
ones based on the major pathological distribution within the brain. The literatures of
recent knowledge about clinical features of other dementias than Alzheimer's and
vascular ones, which were most frequently experienced by many clinicians were
reviewed. That is, cortical dementias such as Pick's disease, frontal lobe type dementia
and non-Alzheimer's type lobar atrophy including fronto-temporal dementia, progressive
dysphasia, fronto-temporal dementia with motor neuron disease, and alcohol-related
dementia were reviewed. Subcortical dementias such as dementias accompanying
Parkinson's disease, Huntington's disease and progressive supranuclear palsy, and
cortical-subcortical dementias such as Lewy body dementiaq and cortical-basal
degeneration were also reviewed. As multifocal dmentias, prion dementias including
KUru, Creutzfeldt-Jakob disease, fatal familial insomnia and Gerstmann-Strussler
-Shrinker syndrone, and AIDS dementia were also reviewed.
