The woman has a brain that is structurally and physiologically different from the male; it is smaller and has a different distribution of neurons, has a functional organization more symmetric than male. So the aging brain is completely different, in the man the executive functions are impaired, overall the ability to do things. In the woman is the anterograde memory impairment (for recent events) that is gradually lost.

In women besides memory loss there is  a estrogen deficiency after menopause. It is essential to have a supplementary estrogen before their final break, otherwise the brain receptors responsible for dementia are no longer responsive to estrogen. The best choice will fall not on estrogen synthesis, but on treatment with bio-identical hormones derived from the plant kingdom and are very similar to our natural hormones.

Moreover, the lower brain mass of women with men leads to an increased frequency of Alzheimer’s in women.
