Alzheimer's disease is an irreversible brain disorder that destroys a person's memory and thinking skills. It is a disease that affects millions of Americans. This four-part documentary series focuses on the causes, symptoms, treatment and possible cures of the progressive brain disorder, and takes a close look at the effects the fatal disease has on both the patients and their loved ones. The series is part of a larger project, which includes 15 supplemental short films, a website and a national outreach campaign, to bring forth a new understanding of the disease.
