Robert Whitaker’s new book “Anatomy of an Epidemic,” is the first book to investigate the long-term outcomes of patients treated with psychiatric drugs. He finds that, overall, the drugs may be doing more harm than good. “Over time, patients with schizophrenia do better off medication than on it. Children who take stimulants for ADHD, he writes, are more likely to suffer from mania and bipolar disorder than those who go unmedicated.”
