More women than men have Alzheimer’s disease and other dementias. Almost two-thirds of all Americans living with Alzheimer’s are women. Of the 5.2 million people over age 65 with Alzheimer’s in the United States, 3.4 million are women and 1.8 million are men. Based on estimates from ADAMS, 16 percent of women aged 71 and older have Alzheimer’s disease or other dementia compared with 11 percent of men.
Further analyses show that the larger proportion of older women than men who have Alzheimer’s disease or other dementia is primarily explained by the fact that women live longer on average than men. Moreover, many studies of the age-specific incidence (development of new cases) of Alzheimer’s disease or any dementia have found no significant difference by gender. Thus, women are not more likely than men to develop dementia at any given age.
Men just die earlier.
