Long-lasting dissociative amnesia.

ABSTRACT

This case report describes a 29-year-old man, who was admitted to a psychiatric hospital due to a severe depressive episode without psychotic symptoms. After two weeks he developed acute retrograde autobiographical amnesia. No organic cause was identified, and the patient was therefore diagnosed with dissociative amnesia. The depressive symptoms ceased as the amnesia developed. After five months of follow-up in the outpatient clinic, his amnesia for the time preceding its outbreak remained unchanged. He patient managed to resume a functional daily life.
