ADHD is associated with a number of other clinical diagnoses. Researchers from the CDC, the University of Florida-Jacksonville, and the University of Oklahoma Health Sciences Center found that more than half of children with ADHD also had another mental disorder, and these children were more likely to have other problems, such as struggling with friendships and getting into trouble in school or with the police. [19] Studies have demonstrated that many individuals have both ADHD and antisocial personality disorder (ASD). [20] These individual are at higher risk for self-injurious behaviors. ADHD is also linked to addictive behavior. The more severe the symptoms of ADHD, the greater the use of tobacco, alcohol, and marijuana. [21] Some individuals have both ADHD and an autism spectrum disorder. [22]  

Symptoms of ADHD and bipolar disorder may be directly correlated. Patients with ADHD should be assessed for possible underlying or coexisting bipolar disorder, and vice versa. [23]
