Ha! It's worse than that IMO. You may already know this. There are 1000's of questions, symptoms, and behaviors that lead someone to diagnose ADD/ADHD. AFAIK there are zero tests to confirm that hypothesis. There are also no tests to know which drug to prescribe, how much, how often, when to administer, etc. That is all done by trial and error.
I helped get dozens of ADD, ADHD, OCD, ODD kids off meds. It was rare that one had to stay on them, but it did happen. Most times it was lack of structure and discipline that came out as a behavioral issue that got diagnosed as a mental health problem. It was our job to put the structure and discipline back in their lives. Sometimes it worked out. Sometimes it didn't. Free will and all. The kid always gets a say.
But over 6 years I would put just a handful of kids in the legit mental health category. I'd put most in the poor parenting, poor peer choices, and lazy categories. When you get kids where the pills are not working, then the pills are not the answer.
Thats what I was getting at. My youngest was diagnosed, by the females in the family, early on as being ADD. so of course the wife needed actual Drs. diagnosis.
We made the appointment for the test. The day of the test I arrived later that the wife and kid so I got to fill out my questionnaire after the Dr had read my wife's questionnaire. The Dr finished her tests with my kid, came out , read over my questionnaire, and literally said "oh, wonderful. Before reading your answers I was going to diagnose your kid with ADHD, with specific xxx and yyy sud type. After reading your responses, I think he has just ADHD with no specific subtype ". Right then and there i determined that ADHD is more about peoples perception than a reality.
My son was around 4 when we got that diagnosed and I fought to keep him off the drugs. He started kindergarten and he did have trouble learning, simple stuff like memorizing the ABCs were very difficult for him. He came home one day and while we were working on his homework he told me that he felt dumb and not as smart as the other kids. We decided to give the medz a try. They did help, a lot.
Each year at his annual physical check up, his primary dr would ask how things are going with school and each year the wife would tell him that our son seemed to be struggling with his school work. Each year they would increase his dosage. This would always cause a lot of arguments between me and the wife.
I developed a plan, when he was in the 4th grade I basically forbid them to increase his dosage. He was a straight A,B student at the time. I knew he was about to hit puberty and start having growth spurts. So my plan was to basically keep him on the same dosage level and let him grow and titrate the effects of the meds. Dosage is based on weight, I figure if he doubles his weight, then the med dosage is halfed. Plus as he was growing and the effects were lessened slowly, he would start learning how to learn and adapt to life and work slowly weaning off the meds.
I got the wife to agree to this with the caveat that if his grades got in the C, D range we would up the dose.
By the end of his 6th grade year he had more than doubled in weight, he was a straight A student and was inducted into Jr Beta club. During wis annual physical with the primary dr, we told the Dr that we wanted him off the meds. The Dr looked at everything thing and said that with the dosage he was on and the weight he was at that the dosage level was technically safe enough that he could stop cold turkey, but the Dr would feel safer if we wiened him off over the course of two weeks. So we followed his advice.
My son has been off the drugs for 2 years now and is still an A, B student.
