There are many studies that show that more elderly people with Alzheimer’s suffer from it than men, and that the prevalence is more than twice as high in women as in men. It is generally believed that the reasons for this situation are multiple. It is because women live longer than men, and in the case of Alzheimer’s disease, women survive longer than men. We all know that the occurrence of Alzheimer’s disease is strongly related to age, and the older the age, the higher the prevalence, so the prevalence is higher in women. It is also believed that women have more estrogen changes in their bodies during menopause; men and women also have different levels of education in early life, and in most cases women have less education than men; there are also women who suffer from depression, anxiety and other mental illnesses often more than men. As we have mentioned earlier and later, the onset of Alzheimer’s disease is related to estrogen, education, and psychological factors, and women have more of these unfavorable factors than men, so it is understandable that their prevalence is higher than men.
