Abstract
Musical release hallucinations are complex auditory phenomena, affecting mostly the deaf geriatric population, in which individuals hear vocal or instrumental music. Progressive hearing loss from otosclerosis disrupts the usual external sensory stimuli necessary to inhibit the emergence of memory traces within the brain, thereby "releasing" previously recorded perceptions. Responses to conventional antipsychotic agents have been variable and extrapyramidal and other side effects have limited their use. We report the first case of hypnogogic release hallucinations successfully treated with the atypical antipsychotic quetiapine. The patient is an 88-year-old woman with progressive deafness who complained of hearing the piano, drums, or a full orchestra every time she was about to fall asleep. She accused her neighbor of hosting loud parties. Physical, neurologic, and psychiatric examination and work-up were unremarkable. She was treated with low-dose quetiapine affording near total resolution of hallucinations without adverse effects. (J Geriatr Psychiatry Neurol 2000; 13:210-211).
