Attention Deficit Hyperactivity Disorder (ADHD) - Symptoms

The three types of ADHD symptoms include:

  • Trouble paying attention (inattention). People with ADHD are easily distracted. They have a hard time focusing on any one task.
  • Trouble sitting still for even a short time (hyperactivity).Children with ADHD may squirm, fidget, or run around at the wrong times. Teens and adults often feel restless and fidgety. They aren't able to enjoy reading or other quiet activities.
  • Acting before thinking (impulsivity). People with ADHD may talk too loud, laugh too loud, or become angrier than the situation calls for. Children may not be able to wait for their turn or to share. This makes it hard for them to play with other children. Teens and adults may make quick decisions that have a long-term impact on their lives. They may spend too much money or change jobs often.

These symptoms affect all people who have ADHD. But typical behavior varies by age.
