Multidisciplinary assessment of patients with musical hallucinations, tinnitus and hearing loss.
BACKGROUND
Although auditory hallucinations are considered a psychopathological phenomenon, musical hallucinations have been reported in individuals without psychosis but with auditory symptoms (tinnitus and/or hearing loss). Thus, a possible different cognitive functioning may be involved in musical hallucinations. The aim of the study was to characterize patients with tinnitus and musical hallucinations through a multidisciplinary assessment, allowing a better understanding of these concomitant phenomena.


METHODS
As this sample is rare to find, all consecutive patients with tinnitus, hearing loss and musical hallucinations were included over a 3-year period, excluding those unable to respond. All subjects underwent the following assessments: (1) otolaryngological and audiological assessment (physical examination and audiometry), (2) neurological assessment (cognition, electroencephalogram and imaging examination) and (3) psychiatric assessment (structured interview).


RESULTS
A total of 16 patients were included (87.5% women; mean age 61.43 ± 15.99 years). The otolaryngological examination was normal in all cases, but audiometry revealed that the degree of hearing loss was severe to profound in 68.75% of participants. Neurological assessment showed electroencephalogram changes in only 17.6% of cases, while 25% presented with mild attention deficit and 43.75% had small foci of gliosis or ischemia on the imaging examination. Psychiatric assessment showed that 68.75% of cases had depression, 6.25% had anxiety disorder and 25% had no psychiatric conditions.


CONCLUSIONS
Musical hallucinations were strongly associated with female elderly adults and with mood disorders. Thus, in contrast to common auditory hallucinations, patients with musical hallucinations associated with tinnitus and hearing loss should be offered a more multidisciplinary assessment.
