問題詳情

請依下文回答第 29 題至第 33 題：Years ago, many scientists assumed that a woman’s heart worked pretty much the same as a man’s. But as morewomen entered the male-dominated field of cardiology, many such assumptions vanished, opening the way for newapproaches to research and treatment.A similar shift is underway in the study of Alzheimer’s disease. It has long been known that more women thanmen get the deadly neurodegenerative disease, and an emerging body of research is challenging the common wisdomas to why. Although the question is by no means settled, recent findings suggest that biological, genetic and evencultural influences may play heavy roles.Of the more than 5 million people in the United States who have been diagnosed with Alzheimer’s, the leadingcause of dementia, two-thirds are women. Because advancing age is considered the biggest risk factor for the disease,researchers largely have attributed that disparity to women’s longer life spans. The average life expectancy for womenis 81 years, compared with 76 for men. And even after taking age into account, women are more at risk.With the number of Alzheimer’s cases in the United States expected to more than triple by 2050, there is a greaterneed to understand the underlying reasons women are more prone to the disease and to develop gender-specifictreatments. The area of inquiry has been growing in part because of a push by female Alzheimer’s researchers, who haveformed a group to advocate for a larger leadership role in the field and more gender-specific research.
