Psychoacoustics is a fascinating developing field concerned with the evaluation of the hearing sensation as an outcome of a sound or speech stimulus. Neuroaudiology with electrophysiologic testing, records the electrical activity of the auditory pathways, extending from the 8th cranial nerve up to the cortical auditory centers as a result of external auditory stimuli. Central Auditory Processing Disorders may co-exist with mental disorders and complicate diagnosis and outcome. DESIGN: A MEDLINE search was conducted to search for papers concerning the association between Central Auditory Processing Disorders and mental disorders. The research focused on the diagnostic methods providing the inter-connection of various mental disorders and central auditory deficits. MEASUREMENTS AND MAIN RESULTS: The medline research revealed 564 papers when using the keywords 'auditory deficits' and 'mental disorders'. 79 papers were referring specifically to Central Auditory Processing Disorders in connection with mental disorders. 175 papers were related to Schizophrenia, 126 to learning disabilities, 29 to Parkinson's disease, 88 to dyslexia and 39 to Alzheimer's disease. Assessment of the Central Auditory System is carried out through a great variety of tests that fall into two main categories: psychoacoustic and electrophysiologic testing. Different specialties are involved in the diagnosis and management of Central Auditory Processing Disorders as well as the mental disorders that may co-exist with them. As a result it is essential that they are all aware of the possibilities in diagnostic procedures. CONCLUSIONS: Considerable evidence exists that mental disorders may correlate with CAPD and this correlation could be revealed through psychoacoustics and neuroaudiology. Mental disorders that relate to Central Auditory Processing Disorders are: Schizophrenia, attention deficit disorders, Alzheimer's disease, learning disabilities, dyslexia, depression, auditory hallucinations, Parkinson's disease, alcoholism, anorexia and childhood mental retardation. Clinical awareness should be high in order for doctors of the two specialties, psychiatry and otorhinolaryngology-audiology to collaborate.
心理声学是一个引人入胜的发展领域，关注对作为声音或言语刺激结果的听觉感受的评估。神经听力学通过电生理测试，记录由于外部听觉刺激而产生的从第8对脑神经直至皮质听觉中枢的听觉通路的电活动。中枢听觉处理障碍可能与精神障碍并存，使诊断和预后复杂化。设计：进行了一项医学文献数据库（MEDLINE）检索，以查找有关中枢听觉处理障碍与精神障碍之间关联的论文。该研究聚焦于提供各种精神障碍与中枢听觉缺陷之间相互联系的诊断方法。测量与主要结果：使用关键词“听觉缺陷”和“精神障碍”进行医学文献数据库检索时，共找到564篇论文。其中79篇专门提及中枢听觉处理障碍与精神障碍的关系。175篇与精神分裂症相关，126篇与学习障碍相关，29篇与帕金森病相关，88篇与诵读困难相关，39篇与阿尔茨海默病相关。对中枢听觉系统的评估通过多种测试进行，这些测试主要分为两类：心理声学测试和电生理测试。中枢听觉处理障碍以及可能与之并存的精神障碍的诊断和管理涉及不同专业。因此，至关重要的是，所有专业人员都应了解诊断程序中的各种可能性。结论：有大量证据表明精神障碍可能与中枢听觉处理障碍相关，并且这种关联可以通过心理声学和神经听力学揭示出来。与中枢听觉处理障碍相关的精神障碍包括：精神分裂症、注意力缺陷障碍、阿尔茨海默病、学习障碍、诵读困难、抑郁症、幻听、帕金森病、酗酒、厌食症和儿童智力发育迟缓。为使精神科和耳鼻咽喉 - 听力学这两个专业的医生进行协作，临床意识应得到提高。
