Psychotherapy may be necessary when the amnesia is due to a psychologic reaction. The recovery is often gradual, the memory slowly reclaiming isolated events while others are still missing. However, previous studies have produced controversial results particularly concerning the temporal extent of. In another form, only certain isolated events are lost to memory.Īmnesia victims usually have a good chance of recovery if there is no irreparable brain damage. Retrograde amnesia (RA), which includes loss of memory for past personal events (autobiographical RA) and for acquired knowledge (semantic RA), has been largely documented in patients with amnestic mild cognitive impairment (aMCI). When amnesia results from a single physical or psychologic incident, such as a concussion suffered in an accident or a severe emotional shock, the victim may forget only the incident itself the victim may be unable to recall events occurring before or after the incident or the order of events may be confused, with recent events imputed to the past and past events to recent times. Rarely is the memory completely obliterated. Remote memory is defined as memories encoded over 1 year in the past that has episodic and semantic components 21. The technical term for this is repression. Here we tested a key prediction of single-store models for free recall in amnesia: that people with amnesia will exhibit a memory advantage for the most recent items even when all items are stored in and retrieved from LTM, an effect called long-term recency. TEA is a type of temporal lobe epilepsy that is associated with remote memory impairment 171, 172. Psychologic factors may also cause amnesia a shocking or unacceptable situation may be too painful to remember, and the situation is then retained only in the subconscious mind. larly, Sara (1981) reported that rats exhibit retrograde amnesia after hippocampal damage for a visual discrimination which is not affected in the anterograde direction. Amnesia is usually the result of physical damage to areas of the brain from injury, disease, or alcoholism.
