© 1984 American Academy of Neurology Familial multisystem atrophy with possible thalamic dementiaFrom the Department of Pathology (Neuropathology) and Rose F. Kennedy Center for Research in Mental Retardation and Human Development (Drs. Katz, Horoupian, and Davies), Albert Einstein College of Medicine, and the Bronx Municipal Hospital Center, Bronx, NY; the Department of Pathology (Dr. Naseem), Mt. Vernon Hospital, Mt. Vernon, NY; and the Department of Neurology (Dr. Rothner), The Cleveland Clinic Foundation, Cleveland, OH. We studied a family with progressive dementia, optic atrophy, and spastic paraparesis. Autopsy of one family member revealed multisystem atrophy with widespread degeneration of the thalamus and marked attenuation of hemispheric white matter to account for the-dementia. This family may suffer from a unique disorder, but the findings overlap with other reported cases of thalamic dementia or familial spastic paraparesis.
