Gabor Maté is a Hungarian-Canadian physician. He has a background in family practice and a special interest in childhood development and trauma, and in their potential lifelong impacts on physical and mental health, including on autoimmune disease, cancer, attention deficit hyperactivity disorder (ADHD), addictions, and a wide range of other conditions. Maté’s approach to addiction focuses on the trauma his patients have suffered and looks to address this in their recovery. In his book In the Realm of Hungry Ghosts: Close Encounters with Addiction, Maté discusses the types of trauma suffered by addicts and how this affects their decision making in later life. He believes in the connection between mind and body health. He has authored four books exploring topics including ADHD, stress, developmental psychology, and addiction.
