Semantic memory deficit with a left thalamic infarct

Neurology. 2003 Jul 22;61(2):252-4. doi: 10.1212/01.wnl.0000073145.08816.e2.

Abstract

Previous studies of patients with thalamic lesions have reported consistent word finding difficulties without a proposed etiology. The authors describe a patient with a focal left thalamic infarct, pronounced word finding problems, and a relatively selective impairment in semantic memory for object recall from features. The thalamus is proposed to facilitate electrical activity between brain regions that encode object features, resulting in object recall. Thalamic dysfunction disrupting object recall is a plausible etiology for impaired word finding in some patients.
