Other Disorders Frequently Comorbid with Autism

Abstract

Unfortunately, individuals with autism spectrum disorder (ASD) experience significant distress due to core features of their disorder and, in many cases, co-occurring disorders. Underreporting of comorbidities in this population is common, yet, when they have been reported, prevalence rates are higher as compared to typically developing peers and, in some cases, psychiatric control groups. Our relatively poor understanding of comorbidities in this population has been aided by the phenotypic heterogeneity of ASD and the varied manifestations of comorbid conditions as compared to typically developing individuals. This further complicates the clinical picture and heightens the need for clarity and rigor regarding assessment. In some cases, we have seen attempts to clarify how various comorbid disorders may be uniquely expressed among those with ASD, but more work is needed. Our efforts in these areas will not only improve our ability to accurately identify comorbidities but will also aid efforts toward developing and implementing effective treatments for the betterment of these individuals and their families.
