Severe amnesia after hypoglycemia. Clinical, psychometric, and magnetic resonance imaging correlations.

OBJECTIVE: To determine the correlation between clinical, psychometric, and magnetic resonance imaging (MRI) findings after an episode of hypoglycemic coma resulting in amnesia. RESEARCH DESIGN AND METHODS: Detailed psychometric assessment, especially memory testing, performed with MRI in a man with severe amnesia after hypoglycemic coma. RESULTS: Psychometric testing confirmed impaired immediate recall. MRI findings were consistent with a lesion in the left temporal lobe. CONCLUSIONS: This is the first description of MRI in determining the neurological damage in hypoglycemic coma.
