In 1997, UCSF neurologist Stanley Prusiner won the Nobel Prize for his discovery of infectious proteins called "prions" that cause mad cow disease. That revelation has led to an increased understanding of neurodegenerative diseases such as Alzheimer's, Parkinson's and ALS. We talk with Stanley Prusiner about the future of brain disease research and his new book, "Madness and Memory: The Discovery of Prions -- A New Biological Principle of Disease."
