What is the ADHD Disorder?

ADHD disorder seems to be a very common disorder here in the United States. But, it does not seem to be so prevalent in other countries. Does that mean we are just paranoid and do not know how to control our own kids. Granted, some kids genuinely do have ADHD, but most of the time it is just bad behavior. Besides, why would anyone want kids to sit quietly in their desk 24/7? That is something you do when you are a grown up and these kids are far from that. The nation needs to learn to become better parents and stop getting divorces.
