Abstract

Purpose

Misophonia is not investigated much from an audiological perspective. Our study aims to examine the processing of the auditory retro-cochlear pathways in individuals with misophonia.

Methods

A cross-sectional study was conducted among university students who had misophonia. The revised Amsterdam Misophonia Scale was used to determine the severity of misophonia. Participants were divided into mild and moderate-severe misophonia and compared with the healthy control group. Auditory Brainstem Response testing was recorded from all the individuals with misophonia. The absolute latency, amplitude, inter-peak latency difference, and inter-rate latency difference were compared between the groups.

Results

One-way ANOVA result showed no significant difference in all the parameters of auditory brainstem response between the groups. These results are suggestive of normal brainstem processing in individuals with misophonia.

Conclusions

The study concludes that the auditory pathway up to brainstem areas is intact in individuals with misophonia. Further studies are essential on a larger population for generalizing the results.

恐音症患者的听觉脑干功能

目的性失声症没有从听力学的角度进行过多的研究。我们的研究旨在检查发音障碍患者的耳蜗后听觉通路的处理。方法采用横断面调查方法，对有发音障碍的大学生进行调查。使用修订后的阿姆斯特丹失声症量表来确定失声症的严重程度。参与者被分为轻度和中度重度发音障碍，并与健康对照组进行比较。记录所有发音障碍患者的听觉脑干反应测试。比较两组之间的绝对潜伏期、振幅、峰间潜伏期差异和速率间潜伏期差异。结果单因素方差分析结果显示，两组听性脑干反应的各项参数无显著性差异。这些结果提示发音障碍患者脑干处理正常。结论本研究的结论是，发音障碍患者的脑干听觉通路是完整的。为了推广结果，对更大的人群进行进一步的研究至关重要。

期刊介绍： Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
