Bilateral hippocampal infarction and amnesia: A case report.
INTRODUCTION The hippocampus along with other structures of the medial temporal lobe plays an important role in the process of learning and memory consolidation. Bilateral hippocampal lesions lead to persistent anterograde amnesia while unilateral damage results in milder, content-specific forms of amnesia. Hippocampus may be affected by an acute or chronic pathologic process from a wide spectr...
متن کاملHippocampal contributions to recollection in retrograde and anterograde amnesia.
Lesions restricted to the hippocampal formation and/or extended hippocampal system (hippocampal formation, fornix, mammillary bodies, and anterior thalamic nuclei) can disrupt conscious recollection in anterograde amnesia, while leaving familiarity-based memory relatively intact. Familiarity may be supported by extra-hippocampal medial temporal lobe (MTL) structures. Within-task dissociations i...
متن کاملAnterograde and retrograde amnesia in rats with large hippocampal lesions.
A test of socially acquired food preferences was used to study the effects of large lesions to the hippocampal formation (HPC) on anterograde and retrograde memory in rats. In the anterograde test, rats with HPC lesions normally acquired the food preference but showed a faster rate of forgetting than control groups. When the food preference was acquired preoperatively, HPC groups exhibited a te...
متن کاملPostoperative anterograde amnesia.
The problems of defining and estimating preand postoperative amnesia are discussed. The extent of postoperative (anterograde) amnesia in patients receiving pre-operative medication (consisting of atropine, pethidine and pentobarbitone) followed by general anaesthesia (consisting of thiopentone, halothane and nitrous oxide) was ascertained. Two control groups were employed; one received spinal a...
متن کاملIschemic bilateral hippocampal dysfunction during transient global amnesia.
A 60-year-old woman was referred to our clinic for the sudden onset of anterograde and retrograde amnesia. She was alert and communicative and repeatedly asked the same questions with no changes of consciousness or loss of self-awareness. She had no prior history of migraine, epileptic seizures, head injury, or stroke, and no other neurologic symptoms beside headache were present. The amnesic s...
