Comorbid Conditions, Emotional Distress, and Dysfunctional Cognitions
At least 70% of adults with ADHD have at least one comorbid disorder. Substance abuse is common. Why are people with ADHD more likely to have anxiety and depression? Perhaps there is shared genetic vulnerability. Perhaps certain environmental risk factors increase both the risk of ADHD and anxiety or depression. Plus, the stresses of living with ADHD make people feel anxious and depressed. Adults with ADHD feel more stress and have more stressors. Adults with ADHD may be especially prone to worry, rumination, and negative automatic thoughts. ADHD is not caused by maladaptive cognitions, but adults with ADHD have more negative automatic thoughts, even when they are not depressed. Maladaptive positive cognitions can be problematic as well and often maintain dysfunctional behavior in adults with ADHD.
