For context: Dr. Gabor Maté is a world-renowned medical doctor, who runs a family practice (as a GP) and a specialist in childhood development and trauma. He has written multiple best-selling books on the topic. However, his views on ADHD (first published in 1999 and recently resurfaced in multiple podcast interviews) are often disputed by experts on the subject.

Dr. Russell Barkley is a retired neuropsychologist and clinical professor of psychiatry specializing in ADHD. He is one of the world's leading experts on the subject. This is his video, debating/debunking Dr. Maté's claims about ADHD.

This kind of stuff (Matè) makes it hard for me to maintain composure. Especially Barkley==Ciba Geigy shill falsehoods. Barkley continues to clearly show overwhelming evidence of the existence, severity, and genetic basis of ADHD.
