Using an extensive clinical history, mental status examination, collateral interviews, neurological examination, electroencephalogram (EEG), intelligence testing, Minnesota Multiphasic Personality Inventory (MMPI), and the Dissociative Experiences Scale (DES), the authors examined twenty-five consecutive psychogenic amnesia patients diagnosed with modified DSM-III-R criteria. In most cases the amnesia was selective, chronic, and not of sudden onset. A few cases were repetitive. There were multiple stressful psychological precipitants. There were many similarities to patients with multiple personality disorder, providing further proof that dissociative disorders occur along a dissociative spectrum. Psychogenic amnesia is probably the most common dissociative disorder diagnosis. It is frequently overlooked because the symptoms are subtle, and other primary diagnoses are often present.402182 bytesapplication/pdfen-USDissociation : Vol. 5, No. 2, p. 073-079 : Psychogenic amnesia: a clinical investigation of 25 casesPsychogenic amnesia: a clinical investigation of 25 casesArticle
