Estimulação transcraniana de corrente contínua no transtorno do processamento auditivo central: comparação de casos clínicos

Abstract

Objective: To describe the findings of Cortical Auditory Evoked Potentials (CAEP) pre and post intervention in individuals submitted to auditory training alone and individuals submitted to auditory training associated with tDCS. Methods: This is a descriptive study. Four female patients participated in the research, two aged 23, one aged 22 and the other aged 21. The participants were submitted to anamnesis, pure tone audiometry, behavioral exams and electrophysiological exams. The research procedure of this study was the CAEP pre and post intervention. Participants were randomized into two distinct groups. One group underwent individual auditory training, while the other underwent auditory training associated with Transcranial Direct Current Stimulation (tDCS) over a period of 8 months. Participants were reassessed 15 days and one month after the intervention.Results: After reassessment, it was found that there was a reduction in latency and an increase in amplitude of the P1 component in the group submitted to auditory training associated with Transcranial Direct Current Stimulation (tDCS). Conclusion: The combination of Transcranial Direct Current Stimulation (tDCS) with auditory training can bring significant benefits to patients with Central Auditory Processing Disorder (CAPD).
