The Nun Study is a longitudinal study of aging and Alzheimer’s disease. It began in 1986 as a pilot study on aging and disability using data collected from the older School Sisters of Notre Dame living in Mankato, Minn. In 1990, the Nun Study was expanded to include older Notre Dames living in the midwestern, eastern, and southern
regions of the United States. The goal of the Nun Study is to determine the causes and prevention of
Alzheimer’s disease, other brain diseases, and the mental and physical disability associated with old age.
