Altered auditory processing has been increasingly recognized as a non-motor feature in parkinsonian disorders. This systematic review provides an overview of behavioral and electrophysiological literature on central auditory processing in patients with Parkinson's disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP). A systematic database search was conducted and yielded 88 studies that met the intelligibility criteria. The collected data revealed distinct impairments in a range of central auditory processes in PD, including altered deviance detection of basic auditory features, auditory brainstem processing, auditory gating and selective auditory attention. In contrast to PD, literature on central auditory processing in atypical parkinsonian disorders was relatively scarce, but provided some evidence for impaired central auditory processing in MSA and PSP. The interpretation of these findings is discussed and suggestions for further research are offered.

帕金森病中的中央听觉处理：系统评价。

改变的听觉处理已被越来越多地视为帕金森氏病的非运动功能。这篇系统的综述概述了有关帕金森病（PD），多系统萎缩（MSA）和进行性核上性麻痹（PSP）患者中枢听觉处理的行为和电生理学文献。进行了系统的数据库搜索，得出了符合清晰度标准的88项研究。收集的数据显示，PD的一系列中央听觉过程存在明显的损伤，包括基本听觉特征的异常检测改变，听觉脑干处理，听觉门控和选择性听觉注意。与PD相比，非典型帕金森病中中央听觉处理的文献相对较少，但为MSA和PSP中的中央听觉处理受损提供了一些证据。讨论了这些发现的解释，并提供了进一步研究的建议。
