About This Condition
Attention deficit-hyperactivity disorder (ADD or ADHD) is defined as age-inappropriate impulsiveness, lack of concentration, and sometimes excessive physical activity.
ADHD has been associated with learning difficulties and lack of social skills. Obviously what constitutes “normal” in these areas covers a wide spectrum; thus it is unclear which child suffers true ADHD and which child is just more rambunctious or rebellious than another. No objective criteria exist to accurately confirm the presence of ADHD. ADHD often goes undiagnosed if not caught at an early age, and it affects many adults who may not be aware of their condition.
ADHD is generally recognized by a pattern of inattention, distractibility, impulsivity, and hyperactivity estimated to affect 3 to 5% of school-aged children. Learning disabilities or emotional problems often accompany ADHD. Children with ADHD experience an inability to sit still and pay attention in class, and they often engage in disruptive behavior.
