Considering the abundance of pediatric diagnoses, with a large increase since diagnostic changes in the 1980s and changes in Medicare coverage, this disorder's diagnosis has been met with a fair amount of criticism. Particularly regarding pediatric diagnosis, many critics claim ADHD is over-diagnosed, assigning a disability to a child simply being a child and medicating them to enforce compliance. Some critics proclaim this increase in medication of children for ADHD is to push drugs on the population and make a buck. Over-prescribing does exist in some areas, however, on the whole, it does not appear to be the case. Not every individual with ADHD is prescribed medication. Just because diagnoses have increased, doesn't mean they're all false positives. Diagnostic criteria has changed as our understanding of the disorder has changed. Though this is still hotly debated, additional research is encouraged to formulate an opinion.
