are parents to blame????

I would first like to mention I am not and expert on add. I don't know if it is a physical problem in the mind or some sort of mental problem (like psychosis, not saying it is)

Whether or not it is mental or physical if it is an epidemic it must be from some reason. It probably stems from all of the chemicals in our diet, our environment, or probably from too much t.v..

Does anyone have any links to case studies on add?
