Case Report: Improved sound perception following auditory management of central auditory processing disorder complicating bitemporal strokes

Introduction This case report describes the potential benefits of auditory training and management for acquired central auditory processing disorder (CAPD), suggesting neuroplasticity and rehabilitation potential in a 57-year-old stroke patient. Methods The patient sustained two temporoparietal ischemic strokes on either side 2 years apart. The first left-sided stroke presented with transient altered processing of speech in noise, followed by spontaneous resolution. The second right-sided insult resulted in left-sided hemiparesis, recurrent listening difficulties, and amusia (altered perception of music). Baseline audiological tests and specialized tests for CAPD were conducted. Results The tests showed profound auditory processing difficulties in the context of only mild presbycusis. Following a course of multifaceted auditory management, the test results showed improved auditory processing skills, in line with the patient's report of better listening. Discussion The findings supported the hypothesis of neuroplasticity in a middle-aged patient following multifaceted auditory management for CAPD secondary to strokes. This case study also highlights that sudden-onset auditory symptoms can be the only presenting features of a cerebrovascular insult.
