Attention-Deficit/Hyperactivity Disorder (ADHD) is a treatable, neurodevelopmental disorder that occurs in kids, teens, and adults.

ADHD affects millions of adults

ADHD is defined as Attention-Deficit/Hyperactivity Disorder.

ADHD is a neurodevelopmental disorder found in children, teens, and adults. Its core symptoms are inattention, impulsivity, and hyperactivity. In an adult with ADHD, symptoms of hyperactivity may be less obvious, but difficulties with inattention, poor planning, and impulsivity may persist. These symptoms can appear at home, work or school, or in social settings. For a diagnosis of ADHD to be made, symptoms must be present in two or more settings.

Symptoms sound familiar? Tell your doctor about your symptoms and how they impact you. The Doctor Discussion Guide can help.

Questions you
may have

  • ADHD can be a lifelong condition, but symptoms may appear differently as you get older. For instance, symptoms of hyperactivity and impulsivity in children may show up as trouble staying seated and blurting out answers in school. In an adult, symptoms of hyperactivity may become less obvious, but difficulties with restlessness, poor planning, and impulsivity may persist.

  • The exact cause of ADHD is unknown, but researchers believe it may be linked to an imbalance in chemical messengers that affect the brain.

  • Complete the Discussion Guide, and take it with you to your next doctor's appointment. Have an open and honest conversation with your doctor about any symptoms that may be affecting you and where you are experiencing them. The guide can help you prepare for that conversation.
