APD is a common secondary diagnosis for children with autism. Processing auditory information is critical to social communication, and people with autism spectrum disorders typically have problems processing information received from verbal communication. Autism is a developmental disability that can cause significant social, communication, and behavioral challenges. People with autism spectrum disorder (ASD) often show difficulties with auditory processing. However, these estimates may be affected by ascertainment bias and the prevalence of APD is yet to be determined.” APD was prevalent in 5% of children and 0.9% of adults of all ages who were referred to a general audiology clinic. estimated a prevalence of APD as 0.5–1% in the general population, based on a prevalence of normal audiometric findings.

In a 2021 Frontiers in Neurology paper, the authors write: “The prevalence of APD was calculated to be 1.94 per 1,000 children by a 2016 retrospective study based on referrals and diagnoses made in a national audiology clinic. Auditory Processing Disorders Demographics
