Abstract
We report a patient who showed a dissociation between impaired semantic memory and preserved autobiographic memory. M.N., a 56-year-old right-handed woman, developed a supra sellar meningioma and underwent multiple operations. Following Lineac radiation, necrosis occurred in the left temporal lobe. Magnetic Resonance Imaging revealed bilateral lesions in the temporal lobes and in the right basal frontal lobe. The patient's intellectual deterioration and anterograde amnesia were mild. Language was preserved, but for a subtle anomia. Autobiographic memory remained intact, while semantic memory for public events, historical figures, cultural items, knowledge of low frequency words and technical terms related to her profession was severely impaired. We hypothesize that bilateral lesions of the anterior half of the middle region of the temporal lobe plays a crucial role in causing deficits in semantic memory.
