Why This Study matters

Many adults with ADHD also struggle with depression, anxiety, or substance use. A common question is whether ADHD medications help these symptoms as well—or whether separate treatment is usually needed.

Key Findings

ADHD medications consistently improved core ADHD symptoms across studies.
For anxiety disorders, some studies reported improvement in specific anxiety presentations, but results were inconsistent.
For depression, some patients experienced reduced depressive symptoms when ADHD symptoms improved, but ADHD medications did not consistently treat major depressive disorder directly.
In substance use disorders, some studies showed reduced cravings or use, but long-term outcomes were mixed.

My Take

This review suggests that ADHD medications are dependable for treating ADHD symptoms, but much less predictably helpful for comorbid psychiatric conditions. Some patients may see secondary improvement in anxiety, emotional dysregulation, or substance-related behaviors, but those effects should not be assumed. In practice, co-occurring conditions often still need their own targeted treatment plan.
