Semantic dementia: aspects of the early diagnosis

S Belliard et al. Rev Neurol (Paris). 2013 Oct.

Abstract

Semantic dementia is a lobar atrophy syndrome, related to a degeneration of anterior temporal regions, and characterized by a very predominant impairment of semantic memory. Whereas the diagnosis is relatively easy to establish in the typical form and if the patient is seen early, the emergence of possible additional cognitive or psycho-behavioural disorders can lead to a misdiagnosis in favour of a frontotemporal dementia syndrome or even probable Alzheimer's disease.

Keywords: Démence fronto-temporale; Démence sémantique; Frontotemporal dementia; Mémoire sémantique; Semantic dementia; Semantic memory.
