Dr. Daniel Amen is a polarizing figure. He is hugely popular, with a string of successful clinics, books and TV shows – but derided by some of his professional peers. The founder of mental and physical health centers, Amen Clinics, believes traditional psychiatry is missing an important component. Dr. Amen says many psychiatrists overlook an extremely important tool of thorough brain analysis. A double board-certified psychiatrist and clinical neuroscientist, he uses single-photon emission computerized tomography (SPECT) scans – which measure brain activity – to address issues like depression, anxiety and attention deficit disorder. In this LLAMA podcast interview with Peter Bowes, Dr. Amen explains his idea of a brain-healthy lifestyle – and why it is key pillar in the quest for a long health span. He also answers critics who have suggested that his methods lack scientific validity.
