Traumatic brain injury can impair the central auditory pathways and auditory cortex. Hence, individuals who suffered a traumatic brain injury may be at risk of central auditory processing disorders, which can be identified with behavioral tests that assess central auditory function.
To characterize and compare the performance of children and adolescents with and without a history of traumatic brain injury in behavioral tests that assess central auditory processing.
The sample comprised 8- to 18-year-old individuals of both sexes who suffered moderate or severe closed traumatic brain injury 3 to 24 months before their participation in the study and whose hearing thresholds were normal. These individuals were matched for sex and age with other subjects without a history of traumatic brain injury and submitted to behavioral assessment of the central auditory processing with special tests to assess hearing skills (namely, auditory closure, figure-ground, and temporal processing), selected according to their chronological age and response-ability.
The study group performed statistically worse than the comparison group in auditory closure, figure-ground in verbal dichotic listening, and temporal ordering. The central auditory processing tests with abnormal results in the comparison group were different from those in the study group.
Central auditory processing disorders were identified in all subjects of the study group, especially involving auditory closure and temporal processing skills, in comparison with subjects without a history of traumatic brain injury.
颅脑损伤可损伤中枢听觉通路和听觉皮层。因此，颅脑损伤患者可能存在中枢听觉处理障碍的风险，可通过评估中枢听觉功能的行为测试来识别。
描述和比较有和无颅脑损伤病史的儿童和青少年在评估中枢听觉处理的行为测试中的表现。
该样本包括 8 至 18 岁的男性和女性，他们在参与研究前 3 至 24 个月患有中度或重度闭合性颅脑损伤，且听力阈值正常。这些个体按照性别和年龄与无颅脑损伤病史的其他个体相匹配，并接受中枢听觉处理的行为评估，使用特殊测试评估听力技能（即听觉闭合、图形背景和时间处理），根据其实际年龄和反应能力进行选择。
研究组在听觉闭合、言语双听的图形背景和时间顺序方面的表现明显差于对照组。对照组中出现异常结果的中枢听觉处理测试与研究组不同。
与无颅脑损伤病史的个体相比，研究组所有个体均存在中枢听觉处理障碍，尤其是听觉闭合和时间处理技能。
