You're absolutely right... ADHD is considered a "chemical imbalance".

The chemical imbalance is the effect. What causes/initiated the chemical imbalance? What is different in one person over another that causes an imbalance? You have to work the equation backwards and separate cause from effect.

When they say it's a chemical imbalance that's when you call them on their diagnosis and say, "OK, model your diagnosis".

This is where the crap hits the fan because they have no model. When you ask these people for a step by step walk through of the process that causes this "chemical imbalance" they can't. They haven't got a clue. Everything that occurs in the body is a discrete mathematical/chemical equation. Every systems analyst knows you can't solve a problem without a walk-through. Things start with Step A and proceed toward End Result Z.

Since the simplest explanation is usually the correct one, which is easier to believe: 1) The child has a genetic defect, 2) the child has been poisoned, 3) the child has mutated with an undetected cancer, 4) the child has picked up one of 5000 viruses or 100,000 strains of bacterium, 5) the teacher is an overbearing jackass that has it in for your kid, or 6) hormones?

I pick 5 first followed closely by 4 if the child is young, but 6 if child is 13yrs. or older, based solely on the way the numbers are likely to break.

Good points.
Another possibility...The child is in a situation they psychologically have problems dealing with early on such as divorce. It gets easier to deal with over time.
So many variables with too little hard data and a whole bunch of quackery IMO.
