Attention Deficit Hyperactivity Disorder-Hyperactive-Impulsive Type is typically referred to as ADHD. It is a disruptive behavior disorder characterized by:
• Excessive physical activity
• Restlessness, fidgeting
• Excessive talking
These children are excessive in their behaviors. They move too much, talk too much, interrupt others, intrude on others’ games, cannot settle down, and seem to be driven by an endless motor. Typically they have these symptoms in addition to those of ADD. These symptoms result in a child who is frequently breaking the rules at home, at school, and on the playground, and consequently is not favored by adults or peers.
Symptoms of ADHD often appear in the toddler years, with the first sign most often being the child’s constant and seemingly endless physical motion. His inability to take turns in play and conversation looks very much like the lack of empathy seen in Asperger’s Disorder.
Symptoms of ADHD are quite often seen in children with Asperger’s Disorder, and many are diagnosed with both disorders. Estimates are so wide in range that they are useless, with various studies reporting ranges from 17 percent to 85 percent of children with Asperger’s Disorder also having ADHD. Because the symptoms of ADHD are so obvious and difficult to live with, they often overshadow those of Asperger’s Disorder. Asperger’s Disorder often goes undetected in ADHD children because both the parents and the evaluator fail to consider it. Any child with ADHD who has problems with social skills should also be evaluated for Asperger’s Disorder.
