Complex Changes In The Brain's Vascular System Occur After Menopause

ScienceDaily (June 20, 2008) — Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don’t notice can be more dangerous. In a new study, researchers at the University of Missouri have discovered significant changes in the brain’s vascular system when the ovaries stop producing estrogen. MU scientists predict that currently used estrogen-based hormone therapies may complicate this process and may do more harm than good in postmenopausal women.

"Before menopause, women are much more protected from certain conditions such as heart disease and stroke, but these vascular changes might explain why women lose this protection after menopause," said Olga Glinskii, research assistant professor of medical pharmacology and physiology in MU’s School of Medicine and lead author of the study. “Because the body eventually will naturally adapt to the loss of estrogen, we advise extreme caution when using estrogen-based therapy in postmenopausal women.”
