In all developed countries around the world women are more likely than men to be diagnosed with Alzheimer’s.
And not just a bit more likely: There are more than twice as many women with Alzheimer’s in the world’s so-called seven major markets (the US, France, Germany, Italy, Spain, UK, and Japan).
The most common explanation of this skew towards women is that women tend to live longer than men, and since the chances of getting Alzheimer’s increases with age, more women would develop the disease.
However, when looking at incidence rates, women still have higher rates than men of the same age. Other studies suggest that development of Alzheimer’s is related to heart disease, and since women have a higher risk of heart disease, Alzheimer’s risk also is higher.
Current studies are looking into whether biological and lifestyle factor differences between men and women can explain the difference.
