- Multidisciplinary Assessment of Patients with Musical Hallucinations, Tinnitus and Hearing Loss(2015) ROCHA, Savya Cybelle Milhomem; KII, Marcia Akemi; PEREIRA, Cristiana Borges; BORELLI, Danilo Totarelli; FORLENZA, Orestes; SANCHEZ, Tanit GanzBackground: 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. (C) 2015 S.

- Tinnitus and sound intolerance: evidence and experience of a Brazilian group(2018) ONISHI, Ektor Tsuneo; COELHO, Claudia Couto de Barros; OITICICA, Jeanne; FIGUEIREDO, Ricardo Rodrigues; GUIMARAES, Rita de Cassia Cassou; SANCHEZ, Tanit Ganz; GURTLER, Adriana Lima; VENOSA, Alessandra Ramos; SAMPAIO, Andre Luiz Lopes; AZEVEDO, Andreia Aparecida; PIRES, Anna Paula Batista de Avila; BARROS, Bruno Borges de Carvalho; OLIVEIRA, Carlos Augusto Costa Pires de; SABA, Clarice; YONAMINE, Fernando Kaoru; MEDEIROS, Italo Roberto Torres de; ROSITO, Leticia Petersen Schmidt; RATES, Marcelo Jose Abras; KII, Marcia Akemi; FAVERO, Mariana Lopes; SANTOS, Monica Alcantara de Oliveira; PERSON, Osmar Clayton; CIMINELLI, Patricia; MARCONDES, Renata de Almeida; MOREIRAW, Ronaldo Kennedy de Paula; TORRES, Sandro de Menezes SantosIntroduction: Tinnitus and sound intolerance are frequent and subjective complaints that may have an impact on a patient's quality of life. Objective: To present a review of the salient points including concepts, pathophysiology, diagnosis and approach of the patient with tinnitus and sensitivity to sounds. Methods: Literature review with bibliographic survey in LILACS, SciELO, Pubmed and MEDLINE database. Articles and book chapters on tinnitus and sound sensitivity were selected. The several topics were discussed by a group of Brazilian professionals and the conclusions were described. Results: The prevalence of tinnitus has increased over the years, often associated with hearing loss, metabolic factors and inadequate diet. Medical evaluation should be performed carefully to guide the request of subsidiary exams. Currently available treatments range from medications to the use of sounds with specific characteristics and meditation techniques, with variable results. Conclusion: A review on tinnitus and auditory sensitivity was presented, allowing the reader a broad view of the approach to these patients, based on scientific evidence and national experience.

Some researchers agree on a combination of peripheral and central dysfunctions as the mechanism that causes hallucination. The most accepted physiopathology of musical hallucination associated to hearing loss (caused by cochlear lesion, cochlear nerve lesion or by interruption of mesencephalon or pontine auditory information) is the disinhibition of auditory memory circuits due to sensory deprivation. Concerning the cortical area involved in musical hallucination, there is evidence that the excitatory mechanism of the superior temporal gyrus, as in epilepsies, is responsible for musical hallucination. In musical release hallucination there is also activation of the auditory association cortex. Finally, considering the laterality, functional studies with musical perception and imagery in normal individuals showed that songs with words cause bilateral temporal activation and melodies activate only the right lobe. The effect of hearing aids on the improvement of musical hallucination as a result of the hearing loss improvement is well documented. It happens because auditory hallucination may be influenced by the external acoustical environment. Neuroleptics, antidepressants and anticonvulsants have been used in the treatment of musical hallucination. Cases of improvement with the administration of carbamazepine, meclobemide and donepezil were reported, but the results obtained were not consistent.
