ABSTRACT
Electrophysiological and behavioral assessment of auditory processing has been an important tool for the diagnosis and therapeutic monitoring in individuals after traumatic brain injury. In this case report, the patient underwent electrophysiological and behavioral assessment of auditory processing pre and post acoustically controlled auditory training (ACAT) and six months after the intervention. The ACAT was organized in eight sessions, focusing on the training of auditory abilities of temporal ordering, auditory closure and figure-ground. Post evaluation ACAT showed better results considering the processes of encoding, organization, and non-verbal. Electrophysiological evaluation showed improved morphology and shorter latencies in auditory brainstem response and higher amplitude of long latency auditory evoked potential (P300). During the reassessment six months after of the ACAT, stability and improved behavioral and electrophysiological evaluation were observed. Acoustically controlled auditory training proved to be effective in developing and refining different auditory abilities as demonstrated in electrophysiological and behavioral assessments of the central auditory processing and the benefits were stable long term.
