Excellent documentary that delves into the possibilities for reversing cognitive decline without using drug therapies. Several patients are profiled who discuss their lives before, during, and after working with Dr. Bredesen. This is not some fly-by-night scenario. Dr. Dale Bredesen, MD, the doctor who co-creates the individualized protocols with his patients, is an internationally recognized neurologist with specialty expertise in the mechanisms of neurodegenerative disease. His credentials: - medical degree from Duke University Medical Center. - Chief Resident in Neurology at the University of California, San Francisco (UCSF). - joined Nobel laureate Stanley Prusiner’s laboratory at UCSF as an NIH Postdoctoral Fellow. - held faculty positions at UCSF, UCLA, and the University of California, San Diego. - directed the Program on Aging at the Burnham Institute before joining the Buck Institute in 1998 as founding President and CEO.
