Long-Term Outcomes of Medication — MTA Study

Dr. Ryan Sultan is a Board Certified Adult and Child Psychiatrist, researcher and Assistant Professor of Clinical Psychiatry at Columbia University Irving Medical Center. He is also in private practice with expertise in the evaluation and treatment of ADHD. One in six American boys is now diagnosed with ADHD. In France, it's one in 200. American children are diagnosed with ADHD at rates 30 times higher than other Western nations. We consume 80% of the world's ADHD stimulants despite being 4% of the population.There's no blood test, no brain scan, no biological evidence this "disorder" actually exists - just subjective checklists and lines of questioning. In this essential episode, Dr. McFillin challenges the validity and reliability of ADHD diagnosis, and what unfolds is a stunning revelation about how 7 million children ended up on amphetamines.

What This Article Inadvertently Reveals:

1. The Diagnosis Shopping Game: The article admits that using DSM-IV criteria produces the "highest prevalence rates" compared to other diagnostic systems. Translation: American psychiatry created diagnostic criteria that captures the most kids. This isn't discovering disease - it's widening the net.
2. The 20-Fold Difference They Can't Explain: The article acknowledges a "20-fold greater prevalence of childhood hyperactivity in North America compared with England" in 1970s studies. Their explanation? Different diagnostic practices, not different children. So they're admitting the "disease" depends entirely on who's doing the diagnosing.
3. The Admission Hidden in Plain Sight: The authors state that differences in prevalence "reflect differences in diagnostic practice rather than true differences in behavior." They're literally admitting ADHD prevalence is about diagnostic opinion, not biological reality.
4. Even establishment researchers like Faraone admit that ADHD prevalence varies 20-fold based on diagnostic criteria used, not actual differences in children's behavior. They acknowledge it's diagnostic practice, not disease prevalence, that creates these massive variations. This 2003 paper proves psychiatry has known for decades that ADHD rates are artificially inflated by American diagnostic criteria.

The Irony: This paper, trying to prove ADHD is universal, actually proves it's a diagnostic construct that changes based on which manual you use. That's not how real diseases work.
