A recent scientific study shows that stress and anxiety, which affect middle-aged people, can lead to cavities and narrowing of the brain, as well as memory problems.
A team of scientists at Harvard University discovered that cortisol was responsible for these effects. According to "Arabic".

By examining the results in terms of age, sex, smoking and body mass, researchers found lower scores on memory and thinking tests in people with higher cortisol levels than average levels.
In addition, people with high levels of cortisol had lower brain volume and those with higher levels of cortisol had a brain accounting for 88.5% of the total skull volume.
Cortisol, produced by the adrenal glands, helps the body react to stress and stress.
