Abstract

Purpose of Review

Autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) are both increasing in prevalence and commonly co-occur with each other. The goal of this review is to outline what has been published recently on the topics of ASD, ADHD, and the comorbid state (ASD+ADHD) with a particular focus on shared phenomenology, differential diagnosis, and treatment considerations.

Recent Findings

ASD and ADHD have shared genetic heritability and are both associated with shared impairments in social functioning and executive functioning. Quantitative and qualitative differences exist, however, in the phenotypic presentations of the impairments which characterize ASD and ADHD. For ASD interventions to be maximally efficacious, comorbid ADHD needs to be considered (and vice versa).

Summary

The research on ASD and ADHD suggests some overlap between the two disorders yet enough differences to indicate that these conditions are sufficiently distinct to warrant separate diagnostic categories.

ASD/ADHD overlap peaks during adolescence and the authors concluded that this overlap peaks here due to the increased demands for social adaptation and use of executive functioning skills.

Compared to control participates, twice as many siblings of children with ASD had psychiatric or neurodevelopmental disorders (adjusted RR = 2.5). Siblings of youth with ASD were at increased for risk for ASD (adjusted RR = 11.8) and ADHD (adjusted RR = 3.7) diagnoses. These findings suggest that ADHD and ASD may have common risk factors.
