RETROGRADE AMNESIA [2 records]

Record 1 2011-01-05

English

Subject field(s)
  • Mental Disorders
  • Nervous System
CONT

Many patients with the acute Wernicke-Korsakoff syndrome retain a residual disorder of memory Korsakoff's amnestic syndrome. They are unable to learn new information(anterograde amnesia) and have difficulty recalling established recent memories(retrograde amnesia). Some confabulate to fill gaps in memory. In contrast to the deficit in memory, other intellectual skills and language are better preserved. Lesions involving the midline diencephalon and the dorsal medial nuclei of the thalamus may account for the memory disturbance.

OBS

Wernicke-Korsakoff syndrome is frequently associated with chronic alcoholism, but it may also result from other conditions.

Record 2 2009-03-02

English

Subject field(s)
  • Nervous System
  • Cognitive Psychology
DEF

A process by which information becomes stable, moving from short-term to long-term memory.

CONT

Though the notion of memory consolidation has a long history [...], the exact nature and purpose of the events that transpire after initial registration of information remain obscure. Memory consolidation is inferred from the existence of gradients of retrograde amnesia(RA) after damage to the brain. It is assumed the damage interferes with some time-dependent process that functions to make memory permanently stable.

  • Système nerveux
  • Psychologie cognitive
DEF

Processus mnésique qui permet de rendre stable et résistante l'information stockée en mémoire.

CONT

La trace mnésique évolue au cours du temps. Elle passe par au moins deux états : un état initial dans lequel elle est fragile, facilement effacée par des perturbations du système nerveux, et un état plus tardif, dans lequel elle est beaucoup plus résistante, solide. Elle passe d'un état à l'autre par un processus hypothétique dit de consolidation.
