Dr. Daniel Amen is a psychiatrist and brain health expert who has scanned nearly 300,000 brains over 47 years of practice, and it was a family crisis, his own attempt to save someone he loved, that pulled him into psychiatry in the first place. Everything he teaches traces back to that same instinct: look at the organ before you treat it. In this episode, he joins Justin McMillen to discuss why he believes most of what gets called mental illness is really an untreated brain, the moment a colleague told him on camera he should be arrested for his work, and the five brain types behind addiction that most treatment programs never bother to ask about.
