Despite what the conventional medical model has taught us about cognitive decline and Alzheimer’s, these disorders are actually within our power to stop, slow, and reverse. There’s no better person to talk to about reducing the risk of cognitive deficits and supporting optimal brain health than today’s guest on The Doctor’s Farmacy, Dale Bredesen.  Dr. Bredesen is internationally recognized as an expert in the mechanisms of neurodegenerative diseases such as Alzheimer's disease, and the author of the New York Times bestsellers The End of Alzheimer's, The End of Alzheimer's Program, and his latest book The First Survivors of Alzheimer's: How Patients Recovered Life and Hope in Their Own Words. He has held faculty positions at UC San Francisco, UCLA, and the University of California San Diego. He has directed the Program on Aging at the Burnham Institute before coming to the Buck Institute for Research on Aging in 1998 as its founding president and CEO. He is currently a professor at UCLA.
