Purpose of Review

The present study describes the co-occurrence of internalizing issues (e.g., depression, anxiety, and suicidal ideation and/or attempts) in two common neurodevelopmental disorders [NDDs]: ADHD and ASD.

Recent Findings

Mental health issues in individuals with ADHD and/or ASD are increasingly common, yet there is minimal literature examining how internalizing issues affect the presentation or long-term outcomes of NDDs. Depression, anxiety, and suicidal ideation and/or attempts occur across the lifespan in both ADHD and ASD.


While the mechanisms that underlie the development and maintenance of internalizing mental health issues in ADHD and ASD differ, interpersonal difficulties characteristic of both ADHD and ASD have been identified as significant contributing factors in these relationships. Given the impact of co-occurring internalizing issues on individuals with NDDs’ quality of life, determining how co-occurring internalizing issues influence diagnosis and treatment outcomes in individuals with NDDs is critical.
