Amnesia due to left hippocampal hemorrhage

Abstract

We recently cared for a patient with hypertension who presented with severe amnesia. Magnetic resonance imaging of the brain revealed localized intracerebral hemorrhage in the left medial temporal lobe. There have been only a few case reports of severe amnesia caused by a restricted hemorrhagic lesion in the unilateral medial temporal lobe (Arai et al., 2006). Here, we present an elderly woman who developed severe amnesia due to left hippocampal hemorrhage. The authors obtained informed consent to the publication of this letter from the patient's son, who was her legal guardian.
