Semantic dementia: A form of circumscribed cerebral atrophy
Abstract
Presents case reports of a 67-yr-old man and 2 women (aged 60 and 66 yrs) with primary cerebral atrophy in whom progressive breakdown in language and visual perception are attributed to loss of semantic information. This form of dementia is distinct from that of Alzheimer′s disease and is assumed to represent a form of circumscribed cerebral atrophy with emphasis of pathology in temporal rather than frontal regions of the brain.
