1、Alzheimers disease affects women more than men 老年痴呆症对女性的影响大于男性For more than 25 years, Mary Read was a successful nurse in Lititz, Pennsylvania. But in 2010, at the age of 50, she started having trouble with her memory and thinking, making it difficult for her to complete routine tasks and follow ins

In 2011, her doctor conducted a comprehensive evaluation , including a cognitive （ adj. 认知的）assessment , and found that she was in the early stages of younger-onset Alzheimers, which affects hundreds of thousands of peop

The 36-year-old community health program director was forced to abandon her own career, home and community in Vermont when both of her parents were diagnosed with Alzheimers three months apart. Wolf took the diffic

Alzheimers dementia disproportionately（不同程度）affects women in a variety of ways. Compared with men, 2.5 times as many women as men provide 24-hour c

In addition, women make up nearly two-thirds of the more than 5 million Americans living with Alzheimers today. According to the Alzheimers Association 2016 Alzheimers Disease Facts
6、and Figures, an estimated 3.3 million women aged 65 and older in the United States have the disease. To put that number in perspective, a woman in her sixties is now about twice as likely to develop Alzheimers as breast cancer within her lifetime. Researchers are racing to figure out why. Women gene
7、rally live longer than men, but mounting evidence suggests that longevity alone may not account for the unequal disease burden women face. It remains unclear whether women are truly at an increased risk for Alzheimers. But studies have revealed that there may be distinct biological and genetic12fact

Understanding these differences will be of key importance in devising new, more effective strategies for treating, preventing and diagnosing Alzheimers. Consider the example of heart disease. The death rate dropped by nearly half as aware
9、ness that it was the leading cause of death in women rose dramatically during a 12-year period beginning in 1997. Now, research uncovering biological differences in heart disease is continuing to help doctors fine-tune diagnosis , prevention and treatment for women. For example, cardiologists（心脏科医生）are modifying how they identify potential risk factors, adjusting blood thinner dosages, and prescribing low-dose aspirin ( 阿司匹林 ) depending on a persons sex, particularly for older women who have already had a heart attack. Tackling Alzheimers now requires a similar vision.
