The female brain is structurally and physiologically different from the male brain. It is smaller and has a different distribution of neurons and has a functional organization more symmetric than male brains. Consequently the aging of the brain is completely different; in males, executive functions are altered, the ability to do things, in females there is an impairment of the anterograde memory (recent events) that is gradually lost.
Moreover memory loss is linked to estrogen deficiency in women after menopause. It is essential to supplement estrogen before their final pause, otherwise the brain receptors responsible for dementia are no longer responsive to estrogen.
In addition, female brain mass is less than male’s thus leads to an increased frequency of Alzheimer’s disease in women.
