One hundred years ago, doctors recognized Alzheimer's Disease as a distinct diagnosis. A number of conferences mark this anniversary, including one that starts today (March 29th) at Penn State University Park. This evening at 7, four conference participants will be at WPSU for a "Lobby Talk" to discuss new approaches to the disease. One speaker is Ann Basting, director of the Center on Age and Community at the University of Wisconsin. She spoke by phone with Cynthia Berger.
