They live trying to look younger than they are on the outside. And now, they have the scientific proof that at least they are already inside. The researchers found that healthy women had a "metabolic age of the brain" that was always younger than men of the same chronological age. The difference occurs at the beginning of adulthood and persists until late in life. The technique used was positron emission tomography. It measured the flow of oxygen and glucose in the brains of 121 women and 84 men under two years of age. 20 and 82. The tests revealed how sugar was converted into energy in different parts of the brain of volunteers.
To understand how brain metabolism was different between the bades, the researchers used a computer algorithm to predict the age of people based on brain metabolism measured by the exams.
The way in which the brain uses energy throughout life progresses more gradually in women than in men. Although researchers do not know what the medical consequences will be, this could explain why women tend to stay mentally longer for longer. to The Guardian newspaper. Researchers suspect that something other than hormonal differences is at work because the difference in metabolism remains the same when women enter menopause.
