The women in our lives are irreplaceable, and it is important that they take every precaution to stay healthy.
Last year, the Alzheimer’s Association named women as the “epicenter” of the Alzheimer’s disease crisis. An estimated 3.2 million American women are living with the disease today. Women face a greater risk of developing Alzheimer’s - one in five women are at risk of developing the disease, while for men the risk is 1 in 10. Women are also more likely to be caring for a loved one who has Alzheimer’s.
My collaborators at Mayo and I conducted a study which found that women who had undergone oophorectomy (removal of both ovaries) before the natural age of menopause or experienced early menopause had a 3x greater risk of developing cognitive impairment or dementia. However, estrogen replacement until the natural age of menopause nullifies this risk.
Research has also shown that older adults are at higher risk for long-term cognitive and functional problems following surgery with general anesthesia – and women are at a higher risk for postoperative brain dysfunction than men. In fact, in one study, the women experienced cognitive function decline twice as fast as men, when exposed to the same general anesthesia.
While we strive to understand the increased risk factors women face, what can be done to reduce the risk in the mean time? Risk reduction may hold a stronger importance for women. This includes taking actions we’ve discussed previously in this blog, such as strict adherence to the Mediterranean diet & habitual aerobic exercise. But annual medical check ups to detect and manage chronic diseases like hypertension, diabetes, hypercholesterolemia, and annual gynecological assessments to detect and manage early menopause, are equally important.
While women face an increased risk of developing Alzheimer’s disease, my message to you remains steadfast: You can maintain the health of your brain, and the time is now. What you do today matters for tomorrow.
