Common Health Factor in Women May Raise Dementia Risk, Study Finds
Summary
A new study shows that women who go through menopause earlier may experience faster brain decline and a higher risk of Alzheimer's disease later in life. The research followed thousands of women for nearly 20 years and found links between early menopause, brain changes, and cognitive decline.Key Facts
- The study tracked 2,603 women for up to 18 years using memory tests and brain scans.
- Women who reached menopause earlier had faster mental decline and developed Alzheimer's disease sooner.
- Early menopause was linked to more brain damage seen on MRI scans, especially in white matter areas.
- The study suggests reaching menopause 10 years earlier could mean nearly 2 fewer Alzheimer's-free years.
- The loss of estrogen during menopause might explain higher Alzheimer's risk in women compared to men.
- Women with premature ovarian insufficiency may face longer periods without estrogen and are often advised to take hormone therapy until around age 51.
- Early menopause does not guarantee Alzheimer's disease; the study shows a connection but not direct cause.
- Researchers highlight managing other dementia risk factors like blood pressure, exercise, and sleep as important.
