The diagnosis of an auditory processing disorder is made by an audiologist with specialized knowledge of auditory processing. Although an auditory processing disorder can be suspected at younger ages, children are most easily diagnosed after the age of seven. To make the diagnosis, an audiologist will first make sure that the child does not have a hearing loss. Then, the audiologist will have a child participate in a variety of tasks that require them to listen to sounds, words, and sentences and respond in different ways. A child’s performance on these tasks can help an audiologist determine if a child has a true auditory processing disorder. The audiologist might also use some tests that can determine just how the child’s brain responds to auditory information.
