Abnormal repetitive and stereotypic behaviors, restricted interests in early childhood, and deficiency of social communication are the characteristic clinical features of ASD, and boys are more likely to be affected than girls ( 1, 2). In addition to these, several studies have reported deterioration in speech perception and expression in patients with autism spectrum disorders, which may also be related to central auditory processing disorders in this unique group of individuals.Īutism spectrum disorder (ASD) is a heterogeneous group of disorders with an estimated prevalence of approximately 14. Most of the studies investigating central auditory processing disorders in patients with autism spectrum disorders have used electrophysiological measurements such as mismatch negativity and P300 event-related potentials. There is an increasing amount of effort for studies regarding the link between autism spectrum disorders and central auditory processing disorders. Among these studies, some have addressed central auditory processing disorders. Several studies confirm that most of the individuals with an autism spectrum disorder have some degree of sensory dysfunction related to disorders of processing auditory, visual, vestibular, and/or tactile stimuli. This article provides a comprehensive review of the studies that are relevant to autism spectrum disorders and central auditory processing disorders and also discusses the relationship between autism spectrum disorders and central auditory processing disorders in the light of recent studies on this subject, which may provide new pathways in a therapeutic perspective. Although children may need extra help and support at school, they can be just as successful as their classmates.The etiology and the underlying pathogenetic mechanisms of autism spectrum disorders are still largely unknown. This is because they develop the skills to deal with it. Many people with APD find it gradually becomes less of an issue over time. Rooms with hard surfaces cause echoes, so rooms with carpets and soft furnishings work best. Asking your child to repeat back what you have said is also helpful.Reducing background noise, such as from the television or radio.Wearing a radio receiver or having a speaker on the desk at school that is linked to a small microphone worn by their teacher may help.Īdjustments at home that will help include:.Using written instructions in addition to verbal instructions.Asking the teacher to check that your child understands what they're being told.Sitting near the front of the classroom.These include:Īdjustments that can be made at school to make things easier include: There are a number of ways to reduce the effects of APD on everyday life. What are the treatments for auditory processing disorder? Assessments that test the way your brain processes information (cognitive tests).Headphones are used to listen to sounds and electrodes are placed on your head to measure your brain's response. Other tests that may be used to help diagnose APD include: Therefore more complex tests are needed, including the ability to hear with different levels of background noise, understand poor-quality speech and detect subtle changes in sound. Although children with APD may seem to have a hearing impairment, this is not usually the case, as hearing for pure tones is within the normal range when tested. The usual hearing tests aren't effective at diagnosing APD because they're usually carried out in a quiet room without distractions and don't test the ability to hear in normal day-to-day situations.
