Document Summary
Attention deficit/ hyperactivity disorder (adhd): developmental disorder featuring maladaptive levels of inattention, excessive activity, and impulsiveness. Inattention: appears not to listen to others, difficulty sustaining attention in tasks or in play activities, may not pay attention to details, make careless mistakes, easily distracted, forgetful in daily activities, hyperactivity, fidgeting, always on the go. Impulsivity: blurting out answers before the questions have been completed, having trouble waiting turns. Either six or more symptoms present from one type persisting for at least six months to a degree that is maladaptive and inconsistent with developmental level. Inattention, hyperactivity, and impulsivity often cause other problems in academic performance, increased risk for minor injuries, unpopularity and rejection by peers, and low self-esteem from the negative feedback of people around them. Required for the child to be present with at least some adhd symptoms must be present before childhood. Estimated to occur in about 6 percent of school-aged children.
