What is ADHD?

Children with attention-deficit/hyperactivity disorder (ADHD) may have symptoms that look like1:
  • Being overly active
  • Acting out without thinking about the results
  • Having trouble learning
  • Finding it hard to pay attention
  • Forgetting or losing things
  • Having trouble taking turns
  • Making careless mistakes or taking unnecessary risks
  • Often squirms, fidgets, or bounces when sitting
  • ADHD is a long-term medical condition that can interfere with your child's activities in various situations: at home, with friends, or at school.2,3
  • ADHD is one of the most common brain-based disorders that affects about one in ten school-aged children. Symptoms continue into adulthood for more than half of those who have it in childhood. People who have ADHD may have higher levels of inattention, impulsiveness, and/or hyperactivity than their peers.4
  • ADHD used to be called attention deficit disorder (ADD); both are the same medical condition.3
  • ADHD symptoms start before age 12 years, and in some children, they are noticeable as early as 3 years of age. ADHD symptoms may continue into adulthood.
