Infectious Madness: The Surprising Science of How We "Catch" Mental Illness

"Fascinating…A superb book."—Robert Sapolsky, Stanford professor of neuroscience and neurosurgery and author of Why Zebras Don’t Get Ulcers

What causes mental illness? We’ve long blamed stress, trauma, and brain-chemistry imbalances. But a new theory is quietly achieving critical mass. In INFECTIOUS MADNESS, award-winning science writer Harriet Washington reveals that schizophrenia, obsessive-compulsive disorder, Alzheimer’s, and anorexia also may be caused by bacteria, parasites, or viruses. Weaving together cutting-edge research and case studies, INFECTIOUS MADNESS shows how strep throat can trigger rapid-onset OCD in a formerly healthy teen and how contact with cat litter elevates the risk of schizophrenia. Featuring a new afterword by the author, and rich in science, medical mysteries, cultural nuance, and evidence-based recommendations, INFECTIOUS MADNESS pulls back the curtain on a new paradigm with profound implications for us all.
