Clinical Trial Summary

Complaints about memory and thinking are common in women as they go through menopause. The female hormone estrogen is important for both the health of both the brain and the blood vessels. In Alzheimer's disease there is damage to the blood vessels in the brain. This study will look at how the loss of the female hormone estrogen affects brain function and the health of blood vessels.
