If the definition of ADHD includes 20% of all boys, then I'm inclined to believe the definition takes in too many kids. If 1 in 5 kids has it, then it is normal behavior in that age range.

I don't in anyway shape or form think 20% of boys should be diagnosed with ADHD. I think something is seriously wrong with our society if this is happening.

This. So much this.

But, think of all the children we can get hooked on ritalin! Think of the lifetime of revenue (for big pharma)!
