Abstract

Focal retrograde amnesia is an unusual and theoretically challenging form of memory disorder. The case of a 65-year-old woman presenting with focal retrograde amnesia is reported. Following a cardiac arrest and subsequent hypoxia she remained in a coma for 24 h with evidence of epileptiform activity during the early recovery period. MR scans, 4 and 7 months post-onset, showed mild bifrontal atrophic changes mainly affecting white matter areas. An [F-18]fluorodeoxyglucose resting PET scan 1-year post-onset demonstrated right occipito-temporo-parietal hypometabolism. We were able to document the patient's performance on an extensive range of anterograde and retrogradetests and to monitor her recovery of function by assessing her performanceat 4, 12 and 24 months post-onset. Spared anterograde memory was observed on a range of verbal and non-verbal tests, including matched tasks that compared pre-illness and post-illness onset recollections. In contrast, her performance on retrograde memory tests, using detailed autobiographical and public events verbal and photographic tasks, showed a temporally-graded retrograde amnesia, more particularly affecting memory for autobiographical episodes. Possible mechanisms underlying CH's focal retrograde amnesia are discussed in terms of Damasio's time-locked multiregional retroactivation model. (C) 2001 Elsevier Science Ltd. All rights reserved.
