This link shows a panel of psychiatrists attempting to define ADHD when it comes to symptoms. Dr. Mark Vonnegut tries to explain what it is. I'd like to invite you to watch it, as they come to the conclusion that they do not have a diagnostic test for ADHD, so they cannot prove the validity of this disorder.
This is the disorder that psychiatrists prescribe mind-altering drugs to children for. And they can't even prove it. Watch this clip. If it shocks you as much as it did me, go to www.cchr.com for more information or for information on how to do something about this.
