Amnesia was a psychological state frequently triggered by a distressing experience, leading to some degree of memory impairment. Those affected could retain procedural memories, such as the ability to speak or complete tasks, but struggle to recall personal information like their name, job, or relatives. Stimuli from the past, such as sights or sounds, could potentially act as a catalyst for recovery.
