Thinking Critically About: ADHD — Normal High Energy or Disordered Behavior?

Psychologists debate the definition of attention-deficit/hyperactivity disorder. Some think the current criteria for this diagnosis are too broad. Others perceive a lack of recognition for this disruptive condition.

1 Two school psychologists are debating whether to diagnosis rambunctious and inattentive 6-year-old Jonah with ADHD.

Dr. Hawkins argues that the disorder is real and that diagnosis with treatment would be helpful to Jonah. What is there to say about each of these points of view?
