CAPD is a broad term which indicates a mixture of disorder that has an impact on the way our brain processes the auditory signals or auditory information. Although the Children with CAPD have normal outer, middle and inner ear functioning, they cannot able to process the auditory information in the same way as other children process it, which causes difficulties in understanding speech and interpreting sound. Studies in this area reported that this difficulty happens due to dysfunction in central auditory nervous system. CAPD can affect children as well as adult and literature also reported that males are twice as likely to have CAPD compared to females.
