Blood Flow in Humans
Compared with men, women have faster blood flow to their brains and lose
less brain tissue as they age.
Women have been found to have faster blood flow to the brain than men do,
which might help reduce the effects of aging on cognition. Men tend to lose
brain tissue at a faster rate as they age, which might make them more
susceptible to age-related cognition effects, such as impulsiveness and
memory loss. The decrease of brain tissue in men generally occurs in the
left frontal cortex, the area of the brain primarily responsible for
thinking through consequences and self-control. It starts around the age of
45 and is thought to contribute to men having more severe cases of midlife
crises than women do.
