Complications

ADHD can make life difficult for you. ADHD has been linked to:

• Poor school or work performance

• Financial problems
• Trouble with the law
• Alcohol or other substance misuse
• Frequent car accidents or other accidents
• Unstable relationships
• Poor physical and mental health
• Poor self-image
• Suicide attempts

Coexisting conditions

Although ADHD doesn't cause other psychological or developmental problems, other disorders often occur along with ADHD and make treatment more challenging. These include:

• Mood disorders. Many adults with ADHD also have depression, bipolar disorder or another mood disorder. While mood problems aren't necessarily due directly to ADHD, a repeated pattern of failures and frustrations due to ADHD can worsen depression.
• Anxiety disorders. Anxiety disorders occur fairly often in adults with ADHD. Anxiety disorders may cause overwhelming worry, nervousness and other symptoms. Anxiety can be made worse by the challenges and setbacks caused by ADHD.
• Other psychiatric disorders. Adults with ADHD are at increased risk of other psychiatric disorders, such as personality disorders, intermittent explosive disorder and substance use disorders.
• Learning disabilities. Adults with ADHD may score lower on academic testing than would be expected for their age, intelligence and education. Learning disabilities can include problems with understanding and communicating.
