We are in the midst of a global mental health crisis, and mental illnesses are on the rise. But what causes mental illness? And why are mental health problems so hard to treat? Drawing on decades of research, Harvard psychiatrist Dr. Chris Palmer outlines a revolutionary new understanding that for the first time unites our existing knowledge about mental illness within a single framework: Mental disorders are metabolic disorders of the brain. Brain Energy explains this new understanding of mental illness in detail, from symptoms and risk factors to what is happening in brain cells. Palmer also sheds light on the new treatment pathways this theory opens up - which apply to all mental disorders, including anxiety, depression, ADHD, alcoholism, eating disorders, bipolar disorder, autism, and even schizophrenia. Brain Energy pairs cutting-edge science with practical advice and strategies to help people reclaim their mental health. This groundbreaking book reveals: Why classifying mental disorders as separate conditions is misleading. The clear connections between mental illness and disorders linked to metabolism, including diabetes, heart attacks, strokes, pain disorders, obesity, Alzheimer's disease, and epilepsy. The link between metabolism and every factor known to play a role in mental health, including genetics, inflammation, hormones, neurotransmitters, sleep, stress, and trauma The evidence that current mental health treatments, including both medications and therapies, likely work by affecting metabolism. New treatments available today that readers can use to promote long-term healing. Palmer puts together the pieces of the mental illness puzzle to provide answers and offer hope. Brain Energy will transform the field of mental health, and the lives of countless people around the world.
