The usual manifestation is a disturbance of functions including memory, thinking, orientation, comprehension, calculation, learning capacity, language, and judgment, and these may be chronic or progressive. This paper gives a brief summary of the book, my impression of the book, the strength and weakness, a comparison of the book with three journals, the lessons I’ve learned, and a conclusion.Overall summary. Dr. David Snowden writes about a pilot study he had among the nuns in Mankato, Wisconsin associating educational level and age-related disabilities. This initial research gave him the idea of expanding his study to other convents and focusing on Alzheimer’s disease. In this study, the nuns (75 -104 years old) contracted to give access to their medical and personal histories and to donate their brain tissue after death to Snowden’s project.Among the Catholic nuns. Snowden studied every nun in that community that had the same health care provided, living situation, and income status. Because he could do away with these factors, Dr. Snowden’s research can focus on which behaviors and attitudes most affect aging, especially mental fitness.The Nun Study’s scientific findings are well outlined in this book. These findings include a) Better language abilities are linked to lower dementia risk. b) Diet and exercise are linked to healthy aging and longevity, and c) A positive attitude decreases the risk of age-related problems.The impression of the book. Tracking the lives of 678 elderly nuns who are members of the School Sisters of Notre Dame to assess the effects of aging is not an easy job. It is clear that Snowden had become emotionally involved with his subjects to draw out the many warm and sympathetic anecdotes that filled the book.Among the project findings is a clear correlation between a low rate of Alzheimer’s and high linguistic ability. Snowden has also found a positive relationship between the consumption of certain antioxidants (e.g., lycopene, found in pink grapefruit, tomatoes, and watermelon), an exercise program, and an optimistic outlook and aging successfully. Snowden’s human-centered and compassionate story gives many early insights.
