ADHD is another term they have come up with that describes one of THEIR diseases. While it's true that that you can get these symptoms from chemical poisoning of some sort, it is also true that every child is supposed to fit a certain kind of "normal" that others have set up the rules for that might not be the normal for that child. These children are usually brighter than others around them and may march to the beat of a different drummer, so they are labeled as having ADHD. Being overactive isn't necessarily a sign of pathology. Society pigeonholes all children into the same category as far as behavior goes. We are not all the same nor should we be expected to be. We all have innate abilities and ways that should be respected outside of the medical community's labeling.
