Washington, February 7, 2019 (MIA) - Scientists from the University of Washington, using a PET scan, came to the conclusion that the female brain is younger in almost four years of males. They hope this can explain why the female brain is more resistant to memory loss, and to neurological diseases in old age.
It is known that the aging of the brain is associated with a gradual decrease in metabolism in the brain. By examinations, scientists tried to assess the "age" of that metabolism.
As the mature age progresses, the amount of glucose that is "pumped" to the human brain decreases, which reduces the energy flow. Scientists have labeled sugar-increasing glucose as a marker for the age of the brain. Then there were PET scans (tests for diseases) of over 121 women and 84 men, which enabled them to measure the level of oxygen and glucose that passes through their brains.
Based on the obtained data and using a machine calculation algorithm, the conclusion is that the woman's brain is an average of 3.8 years younger than the actual chronological age.
One of the authors of the statement, prof. Manu Goi'al believes that this is a fairly solid indicator of measurable differences between the sexes.
"Even when we begin to understand how different gender-related factors can affect the brain's aging, we can come up with answers about how it affects brain vulnerability and neurodegenerative diseases," he said.
"Brain metabolism can help us to explain some of the differences that we see between men and women as they age," he added. Goalie.
The tests were attended by people aged 20 to 82 years old, and the younger age of the female brain is not observed only in older women but also in girls.
The next step is monitoring - how this theory takes place in reality, that is, whether people who look mentally younger are really more resistant to reducing brain work.
