Can ADHD Cause Anxiety or Depression? 

PostedOctober 6, 2025
UpdatedOctober 6, 2025

Yes, ADHD, anxiety depression in adults often go hand in hand. Many adults with ADHD experience comorbidity, where multiple mental health conditions occur together, and anxiety or depression are among the most common. These emotional challenges are not merely side effects; they are deeply connected to the everyday difficulties of living with ADHD.  

When ADHD is left undiagnosed or untreated, it can result in years of frustration, missed potential, and strained relationships, all of which may significantly affect mental health. Over time, the stress of managing ADHD symptoms without adequate support can result in chronic anxiety or depressive episodes.

Why Do Anxiety and Depression Often Coexist with ADHD? 

ADHD impacts the brain’s ability to regulate emotions, attention, and stress responses. This makes adults more vulnerable to emotional challenges like feeling overwhelmed, misunderstood, or constantly behind in life. These feelings can fuel anxiety, especially around performance or social situations, and depression, particularly when low self-esteem or fatigue sets in. 

The overlap, or comorbidity, of ADHD with anxiety and depression also complicates diagnosis. Many adults are treated for mood disorders for years before the underlying ADHD is recognised. Treating ADHD without acknowledging coexisting mental health issues or vice versa can leave individuals stuck in a cycle of unresolved symptoms. 

Supporting Mental Health in Adults with ADHD 

Managing ADHD, anxiety depression in adults requires a comprehensive approach. Cognitive-behavioural therapy (CBT) is highly effective for both mood disorders and ADHD, helping to reframe negative thoughts and build healthier coping strategies. Medication, whether for ADHD, anxiety, or depression, may also play a role in balancing brain chemistry. Lifestyle changes, including regular exercise, sleep, and structured routines, can further support emotional resilience. 

If you are navigating both ADHD and mental health challenges, you are not alone. Visit providers like ADHD Certify for personal consultations and integrated care options that address the full picture.
