    Retrograde amnesia is defined as the loss of memory of events and experiences occurring prior to an illness, accident, injury, or traumatic experience such as rape or assault.

    en.wikipedia.org/wiki/Ribot's_law

    Ribot's law of retrograde amnesia was hypothesized in 1881 by Théodule Ribot. It states that there is a time gradient in retrograde amnesia, so that recent memories are more likely to be lost than the more remote memories. Not all patients with retrograde amnesia report the symptoms of Ribot's law.

    Individuals with retrograde amnesia may partially regain memory later, but memories are not regained with anterograde amnesia because they were not encoded properly. [ 8 ] The term "post-traumatic amnesia" was first used in 1940 in a paper by Symonds to refer to the period between the injury and the return of full, continuous memory, including ...

    en.wikipedia.org/wiki/Dissociative_fugue

    Unlike retrograde amnesia (which is popularly referred to simply as "amnesia", the state where someone forgets events before brain damage), dissociative amnesia is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication, DSM-IV codes 291.1 & 292.83) or a neurological or other general medical condition (e ...
