Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is a common condition that affects children and adolescents and can continue into adulthood for some.

The National Institute of Mental Health (NIMH) estimates that 3% to 5% of children have ADHD. Some experts, though, say ADHD may occur in 8% to 10% of school-aged children. Some experts also question whether kids really outgrow ADHD. This means ADHD may be more common in adults than previously thought.

What are ADHD symptoms in children?Symptoms of ADHD in children are generally grouped into three categories: inattention, hyperactivity, and impulsiveness.

What are ADHD symptoms in adults?ADHD in adults looks a little different. Symptoms can include poor organizational skills, often losing things, low frustration tolerance, procrastination, anxiety, and chronic lateness and forgetfulness.
