Benzodiazepines for prominent auditory hallucinations: a report and hypothesis.

A case is reported of diazepam - induced amelioration of prominent auditory hallucinations experienced by a female paranoid schizophrenic. With the assumption that subvocal speech may be primary to such hallucinations, it is proposed that diazepam may have acted by exerting a relaxant effect on speech musculature. This is a hypothesis testable in future research.
