Over 5 million Americans of all ages are estimated to have Alzheimer's disease, the most common form of dementia that affects memory, thinking, and behavior. Researchers around the globe are working to find a cure, studying what happens to the brain, how long people can live with the disease, and whether or not it is reversible. From PBS's popular NOVA series comes "Can Alzheimer's Be Stopped?", a documentary that takes a thorough look at the latest theories, efforts, and studies to find a cure for Alzheimer's disease. The episode, which originally aired on April 13, 2016, clocks in at just over 50 minutes in length with shorter segments that can easily be integrated into classroom lessons or lectures. In addition to the film, readers will find a Learn More section at the bottom of the page, suggesting related essays and video clips.
