Abstract

Semantic dementia is a rare, distinct form of frontotemporal lobar degeneration, characterized by a deficit in semantic memory with relative preservation of attention and executive functions. We report a case of semantic dementia that pre-sented with a 3-year history of progressive word-finding difficulty and prosopagnosia. Brain MRI showed prominent atrophic changes in the left temporal region and neuropsychological tests demonstrated semantic memory deficits.
