Retrograde Amnesia
Captions available
The idea
Retrograde amnesia is the loss of memories formed before the onset of brain injury or illness.
In practice
A patient after head injury recalls childhood clearly and loses the preceding several years.
Where people slip
Loss is usually graded, with recent memories most affected. Total biographical loss is rare outside fiction.
