Oh, just what I need to make me worry more about my reliable forgetfulness…

Men’s Minds Decline More with Age

Everyone becomes a little more forgetful as they get older, but men’s minds decline more than women’s, according to the results of a worldwide survey.

…

Some studies found more age-related decline in men than in women, while others saw the reverse or even no relationship at all between sex and mental decline. Those results could be biased because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they’re the ones that may not have shown such cognitive decline," said study team leader Elizabeth Maylor of the University of Warwick in England.

The new study used data from the BBC Sex ID Internet Survey, conducted between February and May 2005. The survey had more than 250,000 respondents worldwide.

Survey participants completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category as possible in the given time (e.g. "object usually colored grey") and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated by women.

Within each age group studied, men and women performed better in their respective categories on average. And though performance declined with age for both genders, women showed significantly less decline than men overall. Women slowed down more in terms of their decline, but when comparing men and women of the same age, men showed a greater amount of decline.

On the other hand, maybe I’ll forget that I’m forgetting.  So this could be good news.
