Memories12

  • To a large degree, anterograde amnesia remains a mysterious ailment because the precise mechanism of storing memories is not yet well understood, although it is known that the regions of the brain involved are certain sites in the temporal cortex, especially in the hippocampus and nearby subcortical regions. (wikipedia.org)
  • Damage to specific areas can result in reduced or eliminated ability to encode new explicit memories, giving rise to anterograde amnesia. (wikipedia.org)

  • As a result, Molaison's epilepsy became manageable, but he could not form any new memories, a condition known as anterograde amnesia . (newscientist.com)
  • This speculation was sparked by two seemingly key coincidences of one, timing when this protein synthesis stage occurs coincides with the patient's forgetting at 90 minutes or thereabouts, and two, both 'episodic' and 'procedural' memories appear to require successful protein synthesis to occur for long-term memory permanence, and the patient cannot retain any new either episodic or procedural memories -- and this is unusual compared to traditional cases of amnesia.

Symptoms8
Episodic2
  • Patients with anterograde amnesia may have episodic, semantic, or both types of explicit memory impaired for events after the trauma that caused the amnesia. (wikipedia.org)
  • This argument, however, is less than cogent because we know today that partial amnesia can occur and that it can affect certain memory systems such as episodic memory (of events) while leaving semantic (factual) memory intact. (scientificamerican.com)

Cure amnesia2
  • There are currently no treatments that could essentially cure amnesia, but instead, treatments concentrate on condition management. (specialtycareclinics.com)

Profound amnesia2
  • Dr Burgess added: "Amongst our allied health professions, what we did know about from decades of research and hundreds of case studies, is that bilateral damage to the hippocampal and/or diencephalon structures causes profound amnesia, and in the absence of apparent structural damage to these structures, it left an explanation widely open to speculation. (sciencedaily.com)
