ADHD (Attention Deficit Hyperactivity Disorder) is a condition that
can affect children and adolescents. ADHD is one of the most common
childhood psychiatric conditions, affecting 9.5% of school-aged children
in the United States.
The exact origin of ADHD is unknown, but researchers believe the
disorder may be caused by a variety of factors. Learn more about the
causes of ADHD. Children with ADHD generally have problems paying
attention or concentrating. They can't seem to follow directions and are
easily bored or frustrated with tasks. They also tend to move
constantly and are impulsive, not stopping to think before they act.
These behaviors are generally common in children. But they occur more
often than usual and are more severe in a child with ADHD.
