ADHD/sleep disorder connection

I have read more then once about a connection between tiredness and behavior problems in children. If a child is trying to stay awake, they might fidget, move around or talk out of turn. As a parent, I would certainly request a sleep study for my child before getting into medications that alter the brain chemistry.
