Question

Quizplus · Accepted Answer

The sudden loss of ability to recall important personal information without any physical trauma or drug intoxication is most likely due to dissociative amnesia, which is a psychological condition characterized by the inability to recall personal information due to psychological factors such as severe stress, trauma, or emotional conflict. Depersonalization disorder and dissociative fugue are also dissociative disorders that may involve memory disturbances, but they do not necessarily involve sudden loss of personal information. Retrograde amnesia typically involves loss of memory for events that occurred before the onset of amnesia, rather than sudden loss of personal information.
