Lauren Slater approaches this investigation into the discovery and development of mind-altering drugs and treatments from the perspectives of both a psychology PhD and her own experience as a patient ‘sustained on a serotonin booster for decades’. The book examines the scientists, the theory and the impact of drugs from chlorpromazine, which revolutionized the treatment of schizophrenia, through Prozac and MDMA (Ecstasy) to deep brain stimulation.
