ADHD truth or scifi?

its probally just me being cynical but is it just me or is every child that has behaviour issues or doing poorly coming up with a ADHD code nowadays? its the fix all for elementary kids. Now i am versed in psychology so i do know that yes there is a legitamate case for ADHD but i think it is getting used too much for anything that doesn't fall into another category. So i think having the knowledge of a kid coming into my class with a ADHD label doesn't impress me much (thank you shania) i would be skeptical to see if this is a legit case or a work of clinical science fiction.
