The book in which this chapter appears presents the similarities and intersections between autism spectrum disorders and comorbid conditions in children. It describes the prevalence and magnitude of comorbid conditions occurring in conjunction with autism spectrum disorders that complicate diagnosis and can potentially lead to inappropriate treatment and negative outcomes. The book addresses the strengths and limitations of age-appropriate assessment measures as well as activity and motor skill measurement methods. Specific comorbid disorders are examined through the review of core symptoms, prognostic and diagnostic issues and treatment options for children on the ASD spectrum.
