Tinnitus is sound perception in the absence of a sound source. Changes in parameters of latency and amplitude on the auditory event related potentials or long latency potentials waves have been cited in tinnitus patients when compared to a control group.
To perform an assessment of scientific evidence that verifies the possibility of alterations in latency or amplitude of the waves of event related potentials in individuals with tinnitus.
By using SciELO, Lilacs, ISI Web and PubMed, scientific databases, a review was performed. Articles published in English, Portuguese, French and Spanish that correlated tinnitus with changes in event related potentials were included in this review.
Twelve articles were located, however only eight fulfilled the criteria for inclusion.
The sample of selected studies demonstrate that the long latency auditory evoked potentials related to events between the control and tinnitus patients showed some changes in latency and or amplitude in tinnitus patients. There are changes in event-related potentials when comparing patients with tinnitus and the control group. These changes take place considering the severity of tinnitus, tinnitus site of lesion, and capacity for changes after interventions. The event related potentials can help to determine the neurotransmitter involved in tinnitus generation and evaluate tinnitus treatments.
耳鸣是指在没有声源的情况下感知到声音。与对照组相比，耳鸣患者的听觉事件相关电位或长潜伏期电位波的潜伏期和振幅参数发生变化。
评估科学证据，以验证耳鸣患者的事件相关电位波潜伏期或振幅改变的可能性。
使用 SciELO、Lilacs、ISI Web 和 PubMed 等科学数据库进行了综述。纳入了与事件相关电位变化相关的耳鸣的英文、葡萄牙文、法文和西班牙文的文章。
共定位到 12 篇文章，但只有 8 篇符合纳入标准。
所选研究样本表明，与对照组相比，与事件相关的长潜伏期听觉诱发电位在耳鸣患者中潜伏期和/或振幅存在一些变化。在比较耳鸣患者和对照组时，事件相关电位会发生变化。这些变化考虑到了耳鸣的严重程度、耳鸣病变部位以及干预后的变化能力。事件相关电位可以帮助确定参与耳鸣产生的神经递质，并评估耳鸣治疗。
