A recent study at UC Irvine has found that women over the age of 90 are more likely to have dementia than their male counterparts. Of the study participants, 45 percent of the women had dementia while only 28 percent of the men had it. The best-known form of dementia, of course, is Alzheimer's, and it can result in memory loss and gradual restriction of daily activities. According to the U.S. Census, people over 90 are the fastest growing age-group of the population, and two-thirds of those are female. [Eureka Alert]
