Each narrative episode of TDU is a brief 15-minute Update on science-based/evidence-based health discoveries and insights - practical health information that Dr. Douglass shares with his own patients. The interview episodes with topic experts complement the narrative episodes. The TDU team mines and extracts what’s best from conventional, ‘western’/allopathic medicine, as well as from the more non-conventional therapeutic disciplines to fulfill the TDU goal of providing listeners with practical health information, news, and commentary, about health and healing, including sensible lifestyle decisions listeners can make for better health, in four key areas: Psychology, Neurology, Immunology, and Endocrinology - the basis for what’s called ‘Psycho-Neuro-Endocrine-Immunology’ (PNEI). Integrating the best from all medical disciplines.
