A CASE OF BILATERAL THALAMIC LESIONS WITH ANTEROGRADE AMNESIA AND IMPAIRED IMPLICIT MEMORY

Thalamic nuclei appear to play an important role in memory functioning . Severe anterograde amnesia has been reported with lesions of the dor somedial and anterior nuclei and their connections. We report the case of a woman with discrete thalamic lesions involving the anterior and dorsomedial nuclei who had a persistent anterograde amnesia. Contrary to a previous case report describing impairment only with explicit mem ory, this patient had impairment with both implicit and explicit memor y. This case is discussed in terms of the relevant literature associat ing the diencephalon, amnesia, and implicit memory.
