What Other Conditions Can You Have with ADHD? 

PostedSeptember 10, 2025

ByMy Patient Advice

Children and adults with ADHD may experience comorbid conditions with ADHD, meaning they have ADHD along with one or more other mental health or developmental conditions. These co-occurring disorders can complicate the diagnosis and treatment of ADHD, as the symptoms of these conditions may overlap or intensify ADHD symptoms. 

Common comorbid mental health issues include anxiety disorders, depression, and oppositional defiant disorder (ODD). These conditions often coexist with ADHD, making it more challenging for individuals to manage emotions, focus, and maintain relationships. For example, a child with ADHD and anxiety may find it particularly difficult to concentrate in stressful situations, while a child with ADHD and depression may experience low energy and difficulty engaging in daily tasks. 

A dual diagnosis is made when a person is diagnosed with both ADHD and another condition, which can significantly affect their treatment plan. Identifying these comorbid conditions with ADHD is essential to ensure that all aspects of the individual’s health are addressed, leading to more effective treatment strategies.

Common Symptoms 

Inattention 

Co-occurring disorders like anxiety or depression can exacerbate inattention, making it more challenging for individuals with ADHD to stay focused. 

Impulsivity 

The presence of other conditions, such as ODD, may increase impulsive behaviour, complicating the management of ADHD. 

Emotional regulation difficulties 

Comorbid mental health issues can contribute to emotional instability, making it harder for individuals to manage their emotions in various settings. 

Understanding comorbid conditions with ADHD helps in tailoring treatment to address both ADHD and any additional disorders, ensuring a more holistic approach to care.
