Nun Study

How do we know that exercising the brain and keeping it in shape actually yields positive results? One hint as to what lies in store for those that keep their brains fit lies in the research done with nun's at the Sisters of Notre Dame in Minnesota known as the “Nun study”.
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 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.
Dr. David Snowdon of the University of Minnesota is heading the study.
