James Greenblatt, MD.
Finally Hopeful: The Personalized, Whole-Body Plan to Find and Fix the Root Causes of Your Depression
“A groundbreaking book that redefines how we understand and treat depression.”-Mark Hyman, MD
“Psychiatry can do better. Much better. But only if clinicians and their patients take advantage of decades of largely ignored research and clinical results that show depression is not ‘all in your head.’. The research and results show that many of the root causes of depression are in your body. In your digestive system. In
your hormone-producing endocrine system. In your immune system. And, most importantly, in your brain and its connection to all those other systems.”
