Investigative journalist Charles Piller unravels one of the biggest scientific scandals in recent history. Drawing from his book "Doctored: Fraud, Arrogance, and Tragedy in the Quest to Cure Alzheimer's", Charles reveals how falsified data propped up a dominant theory in Alzheimer’s research, diverting billions in funding and delaying real progress. With over 30 million people affected worldwide, Charles talks about the human toll of the disease, the scientific misconduct that shook the field and the faint but growing signs of hope.
