Remaining in Workforce Could Prevent Alzheimer's Disease

My opinion:  I think this study misses some points as it does not attempt to analyze the lifestyles of these workers.  As it mentions later in the article on its website, some of those who continue to work might be self-employed, which may involve less stressful conditions than that of a large company.  Furthermore, the researchers must assess the activities of those who are retired.  Some of the retirees may not engage in socialization, puzzle games, and exercise, which could further skew the results.  By comparing the seniors who are more active with those who are less active, I think we'd find some intriguing results.  Even further, no one in the study was diagnosed in the same way.  To get even more reliable results, a research hospital could use the same few doctors to diagnose dementia patients over a matter of years.  Ultimately, I think it may still be healthy to retire at retirement age, but one must carefully consider how he or she retires.  It is ok to relax a bit, but not too much - keep your mind sharp and it is less likely to wither away.  Any other interesting causes of Alzheimer's?  Feel free to comment.


Putting Off Retirement May Help Stave Off Alzheimer's

MONDAY, July 15, 2013 (HealthDay News) —. As Americans increasingly delay retirement, a new French study indicates this scenario may have a silver lining: a lower risk of developing Alzheimer's disease.
Researchers analyzing health and insurance records of more than 429,000 self-employed workers found a 3 percent reduction in dementia risk for each extra year at the age of retirement. Workers evaluated had been retired for an average of more than 12 years, and 2.65 percent of the group had dementia.
"There's increasing evidence that lifestyle factors such as exercise, mental activities, social engagement, positive outlook and a heart-healthy diet may reduce the risk of developing Alzheimer's disease and other forms of dementia," said Dr. James Galvin. "Now we can add staying in the workforce to this list of potential protective factors."
Galvin, director of the Pearl Barlow Center for Memory Evaluation and Treatment at the NYU Langone School of Medicine, was not involved with the new research.
The study, led by Carole Dufouil, director of research in neuroepidemiology at the French National Institute of Health and Medical Research, is scheduled to be presented Monday at an Alzheimer's Association conference in Boston. Research presented at scientific conferences typically has not been peer-reviewed or published and results are considered preliminary.
