This article titled, “Aging and Alzheimer’s disease lessons from the Nun Study” by David A. Snowdon was mainly focused around Sister Mary. Only 4.5 feet tall and 85 pounds she was born in 1892 and at the time was 101.5 years of age. The article goes into explaining her life background of how she went back to school and received her high school diploma when she was 41 years old and through the years was teaching in different school systems. After being an active retiree she listened to scientists of the University of Kentucky and agreed when the head scientist said that donating your brain for research on Alzheimer’s is very beneficial. She was all for it and joined 678 school sisters in signing up. She almost at the maximum age for the study where the range of ages were from 75 to 102. After being put through a series of tests her last test in the Nun study was Mini Mental State Examination where she scored high which was remarkable due to her age and less formal education than other participants. After death of most of the subjects neuropathical evaluations were completed on 118 sisters. Scientists had many findings with Sister Mary and other sisters such as nuerofibrillary tangles in the neocortex and brain weight. They found that the different scores on the tests given related to the brain function to the sisters after they had past away. One main purpose it seems it his study is to find out what happens in someone’s life that triggers this disease and where it effects. The scientists seem like they want and need more subjects who are whiling to let research be done on them after they move on in life. This seems to be the best way for scientists and other researchers to get a good idea of what can be done and are the leading factors.
