ADHD has seen a significant increase in numbers of children diagnosed with the disorder and not "disease." It can't be called a disease because there are no physical tests that can be done to definitively say, "Yes, we have the proof of this disease." The factors that lead a therapist or teacher to determine if a child has it are questions that can be answered yes to most children today and yesterday.

OVERDIAGNOSIS is not a myth.

This is malarky. But go ahead drug the heck out of the young and vulnerable.
