Comorbidities of Adult ADHD

ADHD and co-occurring conditions

Many adults with ADHD also have co-occurring psychiatric disorders, including

  • anxiety (47%)
  • mood (38%)
  • impulse control (20%)
  • substance use disorders (SUD, 15%)

Symptoms of ADHD can be concealed by more robust symptoms of these co-occurring conditions. Conversely, comorbid anxiety and learning disorders can be obfuscated by more obvious ADHD symptoms.

Some comorbid disorders may be a direct reflection of the impact of ADHD symptoms; for example, poor academic achievement owing to ADHD may lead to anxiety. Additionally, other frequently co-occurring conditions, such as depression, share common environmental risk factors with ADHD.5
