Medical Notes this week…

Women stay mentally sharp farther into old age than men typically do, and scientists now think they know why. It all has to do with how the brain burns energy. A study in the Proceedings of the National Academy of Sciences shows that women’s brains burn energy in a much more youthful way throughout adulthood. Women’s brains appear to be about three years younger than men’s of the same chronological age, even in their 20’s, and that difference holds for the rest of their lives.

Binge drinking and prolonged heavy drinking may trigger a permanent change in a person’s DNA, which results in an even greater desire for alcohol. A study in the journal Alcoholism: Clinical and Experimental Research shows that among binge and heavy drinkers, two genes are modified that influence drinking behavior—one that influences the body clock and another regulating the stress-response system. Scientists hope the findings may eventually help identify biomarkers for people at risk for alcoholic changes.

And finally, more than half of all American workers say they’ve suffered from job burnout, but most of them won’t take a “mental health day” away from the job to deal with it. The University of Phoenix survey shows only a third of workers have taken time off for mental health, mostly because they say their companies don’t view it as an acceptable reason to be off work.
