Psychogenic amnesia.
Time- and content-based memory systems are briefly described so that their importance for a refined analysis of memory disturbances becomes evident. These memory systems are then related to their brain instantiation, emphasizing that there are limbic circuits for encoding different forms of memories, largely cortical networks for memory storage, and a combined temporofrontal network acting to t...
متن کاملRetrograde amnesia.
In humans, the phenomenon of temporally graded retrograde amnesia has been described in the clinic and the laboratory for more than 100 years. In the 1990s, retrograde amnesia began to be studied prospectively in experimental animals. We identified 13 published studies in which animals were given equivalent training at two or more separate times before damage to the fornix or hippocampal format...
متن کاملKetamine induces anterograde and retrograde amnesia in rats
Introduction: The N-methyl-D-aspartate (NMDA) receptors, which have been implicated in memory formation, could be noncompetitively blocked by ketamine. The present study examines the short term effect of ketamine on induction of anterograde and retrograde amnesia in male rats using Morris water maze (MWM). Methods: Male N-MRI rats were randomly divided into nine experimental groups. MWM stud...
متن کاملRetrograde amnesia in Parkinson's disease.
Retrograde amnesia was assessed in demented and non-demented Parkinson's patients using a test of remote memory spanning the years from 1920-1979. Results indicated that the demented patients 1) scored significantly below normal controls and 2) had equal impairment for all time periods. This pattern was like that seen in other dementing illnesses (i.e., Huntington's and Alzheimer's diseases), b...
متن کاملRetrograde amnesia and remote memory impairment.
-The status of remote memory in case N.A., patients receiving bilateral ECT, and patients with KorsakoBsyndrome was assessed using seven different tests. The extent and pattern of remote memory impairment depended upon the etiology of amnesia, appearing as a relatively brief retrograde amnesia for N.A. and patients receiving ECT and as an extensive impairment covering many decades for patients ...
