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

ADHD affects millions of children

ADHD is defined as Attention-Deficit/Hyperactivity Disorder.

ADHD is one of the most common neurodevelopmental disorders in children. Its core symptoms are inattention, impulsivity, and hyperactivity. Between 60% and 85% of kids (ages 6-12) diagnosed with ADHD may continue to have ADHD as teens (ages 13-17), although the symptoms may look different as your child gets older. (See "Questions" below, which provide specific examples of what this change may look like.) These symptoms can affect them at home, at school, and in social situations. For a diagnosis of ADHD, symptoms must occur often, and be present in two or more settings.

Questions you may have about ADHD in children

  • Only a healthcare provider can accurately diagnose ADHD. If you are concerned your child might have ADHD, make an appointment with your child’s doctor. To help prepare for the appointment, complete the Doctor Discussion Guide and bring it with you to the doctor’s office.

  • Medications do not cure ADHD. But they may be able to help people with ADHD control the hyperactive/impulsive and inattentive symptoms of ADHD. Medicine may not be right for everyone with ADHD. If medicine is prescribed, it may be used as part of a total treatment plan for ADHD that could include counseling and other therapies. Learn more about Vyvanse as a treatment option for ADHD.

  • Some ADHD symptoms may become less noticeable as he or she ages. As ADHD may persist from childhood into adolescence, symptoms of hyperactivity in children, such as climbing or running excessively, are less common and may appear in teens as fidgetiness or an inner feeling of restlessness. Teens may also continue to struggle with impulsivity as they get older.
