Musical hallucinations induced by bromocriptine

A case of bromocriptine-induced musical hallucinations in a 67-year-old patient with probable Lewy body dementia is reported. The patient was given bromocriptine for the treatment of parkinsonism. At a bromocriptine dosage of  7.5 mg,  the  patient  complained,  ‘I  hear  karaoke  songs  in  the  inner  part of my head.’ The musical hallucinations gradually decreased after administration of the drug was discontinued. Bromocriptine is known to cause hallucinations, but not musical hallucinations. The dopaminergic effect of bromocriptine and the patient's cognitive impairment might have acted together to generate the musical hallucinations.
