You are just wrong that there is a financial windfall to schools for overdiagnosis -- you are entitled to your opinions, but you are not entitled to your facts -- you wrong about this.
Be that is it may, I argue constantly in schools and with parents for using good sense, prevention and extreme caution when it comes to diagnosis and medication. It is an abonimnation when children are inaccurately diagnosed and prematurely or improperly medicated. But your statement that you can 'pick em out blindfolded' is an insult to those who spend lifetimes trying to understand the nuances of neurological and mental disorders and work tirelessly to effect the most positive results from the least invasive interventions. Your opinion seems to be that parents, educators and mental health professionals are patently unethical. I'm not saying that there are no unethical folks in schools and MH centers, I'd even agree that there are too many, however, you seem convinced that a lack of ethics is the norm. I simply don't see it and don't buy it.
Your statements are an insult to parents. Ritalin is simply not effective enough to solve problems resulting from bad parenting. There are many parents who work their tails off to parent and care for their children, only to find that their children are still faiing. While many parents need to improve their skills, some parents actually need your understanding rather than your disdain. Regarding your statement that the education/MH field is dominated by the non-ethical all I can say is that I have the perspective of having worked with hundreds of schools and thousands of teachers and while I have my issues with the quality of instruction and the organization of systems, I certainly do not feel there is a dearth of ethical conduct. But, that's my opinion.
You point out yourself the folly of comparing ADD/HD with Bi-Polar disorder. You say you have witnessed a boom in diagnosis of ADHD and rest on the assumption that all children have been misdiagnosed. From there, you cite the perception that there is a boom in bi-polar disorder and therefore feel it follows that all these must be misdiagnosed. If I am following your logic correctly, let me just say that I don't follow your logic.
Lastly, I am sorry that you had a relative mistreated and perhaps mis-diagnosed for shizophrenia. It sounds horrible and I don't blame you for anger around this. I also can understand that when you see in front of you a child who you think is inaccurately diagnosed and improperly medicated, it is horrible. But I'll throw out there that it may be true regarding the children that you don't know all there is to know about the child, their history, their diagnosis, or their current plan for treatment. Also, I'll suggest that there are other children and other adults who you don't know, who have been, or are currently being treated successfully with medications (and/or other mental health interventions) and you don't know because they are not telling you. I'll share with you that my mother -- who is 82 and was unable to leave her home for 6 months -- has now resumed her life due to the correct medication.
I am your age-ish (51), Finkelskyhook, and you and I can probably share many things in common about our childhood experiences that differ from today's world. We'll be better off discovering the things we have in common because I can see that you give a [dang] about the kids you mentor and we love the Celts -- there is probably a good deal of good, bad, right and wrong in both of us.
