Retrograde amnesia (RA) is a loss of access to events and information of the past after the onset of disease or injury [1]. RA is often temporally graded, consistent with Ribot's Law : more recent memories closer to the traumatic incident are more likely to be forgotten than more remote memories [ 2 ] .
In neurology, retrograde amnesia (RA) is the inability to access memories or information from before an injury or disease occurred. [1] RA differs from a similar condition called anterograde amnesia (AA), which is the inability to form new memories following injury or disease onset. [ 2 ]
[1] Additionally, the study of patient N.A. has contributed to research on amnesia, especially anterograde amnesia. It gave an insight on the underlying structures and processes of amnesia. The case of N.A. helped to determine the causes of anterograde amnesia and proved that amnesia can be caused by damaging multiple diencephalic structures. [1]
Focal retrograde amnesia (FRA), sometimes known as functional amnesia, refers to the presence of retrograde amnesia while knowledge acquisition remains intact (no anterograde amnesia). Memory for how to use objects and perform skills ( implicit memory ) may remain intact while specific knowledge of personal events or previously learned facts ...
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. The amnesia may cover events over a longer or only a brief period. Typically, it declines with time, with earlier memories returning first. [9]

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.
