Women’s Brain Vulnerable To Alzheimer’s Disease Reveals New Study

New evidence has shown that women’s brain is more vulnerable to Alzheimer’s disease as compared to men. The study indicated that women who have mild cognitive impairment, which is known to lead to Alzheimer’s disease, tend to decline faster than their male counterparts. The research was carried earlier this week at the Alzheimer’s Association International Conference that was held in Washington, D.C. In the second study, it emerged that women’s brains contain more amyloid. This is a substance that handles the formation of sticky plaques in Alzheimer’s disease. Yet a third study showed that women, who undergo surgery that involves general anesthesia, are more likely to develop long-term memory and thinking problems than men.

From this study, it is now evident why women make up two thirds of all Americans living with Alzheimer’s disease, leaving a third to others. The results stand as a challenge to the popular notion that more women live with Alzheimer’s disease since they tend to outlive men. To this, Kristine Yaffe from the University of California, San Francisco says, “There is something else going on in terms of biology or the environment for women.” The research on women who have mild cognitive impairment was just a part of a larger study that is ongoing. The ongoing research is referred to as Alzheimer’s Disease Neuroimaging Initiative. The research took 8 years to study records of approximately 400 men and women who were believed to have mild cognitive impairment, a condition which according to researchers often leads to Alzheimer’s disease.

Katherine Amy Lin, who was part of the team of researchers from Duke University Medical Center said, “We found that women decline at almost twice the rate of men and we also found that women have faster acceleration of decline over time.” The observation that was made from the research showed that, so many women who had subtle memory and thinking problems at the initial stages of the study, had developed major deficits by the end. From the study, it was clear that there exists a difference between men and women in spite of age. Indicating that women are at a higher risk of developing Alzheimer’s disease, Michael Weiner, the study’s senior author said, “Overall, women had more amyloid in their brains than men. What is not clear though is why women’s brain cells are more vulnerable than men’s to Alzheimer’s disease, memory and thinking problems. If scientists can figure out the mechanism that causes more Alzheimer’s disease in women, they might be able to develop treatments that halt the whole process.”
