Madness and Memory

Stan Prusiner received the Nobel Prize of Medicine in 1997 for identifying what at the time was considered a novel mechanism of neurodegeneration: the prions. These “infectious proteins” were responsible for ravaging the brains of animals suffering from scrapie and mad cow disease, and of humans with Creutzfeldt-Jakob disease. Although I have come to doubt that prions are a cause of rapidly progressive dementia and may instead represent a consequence, Prusiner’s memoir is filled with moments of skepticism, self-doubt, adversity, and intellectual rivalries –the ingredients for a gripping drama in neurosciences.
