Descripción
Sumario:We describe a patient (RP) who developed a severe retrograde amnesia in the absence of anterograde memory deficits after a minor closed head injury. The retrograde amnesia affected RP's autobiographical memory as well as his memory for famous people, well known events and semantics. He showed no structural brain lesion on the MRI, but a SPECT study showed right frontal, parietal and thalamic perfusion deficit. While RP could partially relearn some of the lost memories, 1 year after the accident he still showed a dense retrograde amnesia. Our case demonstrates that severe and long-lasting retrograde memory deficits may occur after a 'minor' closed head injury.
