Persistent youth in the aging female brain

Recommended Posts

Eldorado

"Women’s brains are nearly four years younger than men’s, at least in how they burn fuel, according to scans performed by US researchers.

Scientists found that healthy women have a “metabolic brain age” that is persistently younger than men’s of the same chronological age. The difference is apparent from early adulthood and remains into old age.

The finding suggests that changes in how the brain uses energy over a person’s lifetime proceed more gradually in women than they do in men. While researchers are unsure of the medical consequences, it may help explain why women tend to stay mentally sharp for longer."

I wonder how well that agrees with the impressions we get from simple observation. ( women being "sharper" with old age.) I can't say I've noticed it, but maybe I am already losing the mental acuity needed to judge ! However, women live by that much longer anyway, so maybe they need that 4 year lag to get to the end of life with enough "marbles" to cope.

I tend to agree with Habitat about simple observation. There are so many factors that can play into this.

So woen are more mature at the same age as a man and now younger mentally, too?  Boy are we getting the wrong end of the stick!

This study is interesting but it fails to address the more significant fact that women are more likely than men to develop dementia as they age.

Both my mother and my maternal grandmother suffered from dementia.  None of the men in my immediate family ever had problems.
