A Rare Case of Alcohol-Induced Psychotic Disorder (Alcoholic Hallucinosis) Responding to Olanzapine

Muhammad Fahmi Ismail


This is a case of a 40-year-old man with a background history of alcohol dependence syndrome presented with brief history of overt auditory hallucination. His presentation is acute in onset with primary auditory hallucination, retained personality and insight with no evidence of thought disorder or clouding of consciousness. No abnormalities were found following a medical work-up including blood investigation and MRI brain. A diagnosis of alcohol-induced psychotic disorder (AIPD) was made and he was commenced on a second-generation antipsychotic (olanzapine) with favourable response. AIPD is a rare complication of chronic alcohol abuse which leads to acute prominent auditory hallucination and paranoid ideation. Antipsychotic medication remained the mainstay of treatment for AIPD, but the evidence remained quite limited.
