“…We included reports of patients in whom intoxication or inflammatory encephalopathy seemed to be the underlying cause [25,28,61,65,68,81,82,94,99,100,101,102] and another seven cases in whom intoxication seems to at least support the aberrant perception [2,28,32,33,36,56,57]. One case did not present with enough information for inclusion in this review [103].…”

“…Ruiz-Almazán et al [24] described patients with hearing loss and MH associated with depression, mild cognitive impairment and slight alterations in white mattersimilar to descriptions by other authors [8,[25][26][27] . They hold that MH stems from a combination of hearing loss and mild brain damage such as slight cognitive deficits that do not affect activities of everyday living.…”

Multidisciplinary Assessment of Patients with Musical Hallucinations, Tinnitus and Hearing Loss

et al. 2015

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. Sampling and 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.

“…No de fi nite risk factors for musical hallucinations associated with hearing loss have been identi fi ed. A central lesion of the right or left hemisphere and/or a seizure seemed to have a facilitating or triggering role in some cases (Paquier et al 1992 ) . Musical hallucinations may be associated with disorders other than deafness, including psychiatric illness, focal brain lesions (right or left hemisphere), epilepsy, intoxication and in fl ammatory encephalopathy (Berrios 1990 ;Evers and Ellger 2004 ;Stewart et al 2006 ) .…”

The Neuroscience of Hallucinations

View full text Add to dashboard Cite

Hallucinations occur in a great variety of neurological conditions and are facilitated by sensory loss. The common end pathway of their pathophysiology involves the activation of cortical sensory areas implicated in normal sensory processing. Based on the presumed pathophysiology, we here classify the hallucinations in four main groups. In migraine aura and epilepsy, hallucinations result from spontaneous intrinsic overactivity in hyperexcitable sensory cortical areas. Deafferentation, i.e. the loss or impairment of sensory input, facilitates hallucinations in the corresponding sensory modality, probably by leading to chronic hyperexcitability of the corresponding cortical areas. The archetypal example of this mechanism is the Charles Bonnet syndrome, where hallucinations are associated with visual impairment. A third mechanism relies on the dissociation of dream and sleep mechanism, as illustrated by hypnagogic and hypnopompic hallucinations. Finally, in the course of neurodegenerative diseases such as Parkinson's disease and dementia with Lewy bodies, hallucinations are frequent and probably result from a combination of factors, including dysfunction of both bottomup sensory processing and top-down modulatory mechanisms, as well as dream intrusion phenomena and facilitating pharmacological factors.
