Facts about estrogen and Alzheimer's disease

Estrogen is important to the building and maintenance of nerve networks in the brain from early on in life. Several studies are now pointing to the fact that estrogen may offer protection against Alzheimer's disease in postmenopausal women. One study conducted on almost 90,000 postmenopausal women found that those taking estrogen had a significantly longer life and by the time of their deaths, the women on estrogen had a 40 percent lower incidence of Alzheimer's disease. In another related study, estrogen was also associated with a significantly decreased occurrence of the disease. In addition, those women who did develop Alzheimer's disease and were on estrogen replacement therapy seemed to have a milder form of the disease. Additional studies are being conducted to determine just what the protective nature of estrogen is in its relationship with Alzheimer's disease.
