Is it possible to catch autism or OCD the same way we catch the flu? Can a child's contact with cat litter lead to schizophrenia? In her eye-opening new book, Harriet Washington, author of the National Book Critics Circle Award-winning Medical Apartheid, reveals that we can in fact "catch" mental illness. In INFECTIOUS MADNESS, Washington presents the new germ theory, which posits that many instances of Alzheimer's, OCD, and schizophrenia are caused by viruses, prions, and bacteria, and that with antibiotics, vaccinations, and other strategies, these cases can be easily prevented or treated. Packed with cutting-edge research and tantalising mysteries, INFECTIOUS MADNESS is rich in science, characters, and practical advice on how to protect yourself and your children from exposure to infectious threats that could sabotage your mental and physical health.
