There are so many studies now that are finding that many kids with ADHD actually have sleep apnea and when properly diagnosed, and get the right sleep function well. I have also had friends put their kids on a gluten-free and dairy free diet with amazing results in their ability to focus and function. My own friend says it is like night and day and the diet makes a difference. You can read my family health column about ADHD and lack of sleep, there are great links included...too many docs are prescribing drugs w/o looking for the root cause.
Good Luck and feel free to email me if you have more questions.
