"Doctor, my 3 year old totally has ADHD. He cannot sit still. He has a hard time concentrating and staying on task. Can I get something to help with him? Please FIX HIM!"
Diagnosis: normal 3 year old.
ADD/ADHD (I'll just refer to it as ADHD from here on out because I'm lazy) seemed to be all the rage in the 90's. Seems to now to have taken a back seat to 'Autistic Spectrum Disorders'. It is still relevant, and while it doesn't get the press/publicity of autism, it is definitely more common.
First question: Does it really exist, or is it just a reflection of a generation of bad parents?
First answer: Yes, it does exist.
There are many kids that seem to very obviously have this diagnosis. The medication to treat is consists of a group of stimulants. If you give someone a stimulant and it CALMS THEM DOWN, I'd say that's pretty good evidence that they have some 'crossed wires' so to speak. It is a highly genetic situation, so kids with it are likely to have parents that suffered similarly as a child (and some continue to as adults).

Second question: Does my child with ADHD need medication?
Second answer: Maybe.
Second answer: Maybe.

Third question: Isn't it just easier to give them a pill to pop than to learn how to be a better parent?
Third answer: Yes.
Studies clearly show that even with medication, proper parenting techniques are invaluable. Do your kid a favor and get the training you need in order to give them the best chance to succeed. I will admit, though, I have had some parents that are so disorganized and ADHD themselves (its genetic, remember) that I don't even bring up parent training, because I don't believe in exercises in futility.
Fourth question: If I eliminate sugar from his diet, will he be normal?
Fourth answer: Probably not.
There are may people out there trying to sell their diet plans to help with ADHD. There is very little scientific basis for this. Most of the time, it is the case of a person who wants to prey upon someone else who is desperate for help (which describes pretty much any parent of an ADHD child). That doesn't mean they don't help at all. There may be a diet component, but I think these dietary needs can vary wildly between children. I don't see any problem trying different diet routines, as long as it doesn't but an undue financial (or other) stress upon your family. NONE of the diets work for every child. The parenting techniques described above help to some extent for EVERY child. Start with those, then consider diet therapy, but keep your expectations low and your wallet tightly closed.
