Summary

Estrogen replacement therapy (ERT) may protect memory in postmenopausal women. Women on ERT showed better performance on a memory test, suggesting estrogen benefits cognitive function in aging.

Area of Science:

  • Neuroscience
  • Gerontology
  • Endocrinology

Background:

  • Postmenopausal women often experience cognitive changes.
  • Estrogen replacement therapy (ERT) is used for physical health benefits.
  • Emerging evidence suggests ERT may impact cognitive function.

Purpose of the Study:

  • To investigate the protective effect of ERT on memory in nondemented postmenopausal women.
  • To test the hypothesis that estrogen influences cognitive performance.

Main Methods:

  • Examined hormonal status and memory data in 288 postmenopausal women from the Baltimore Longitudinal Study of Aging.
  • Compared cognitive assessment scores between 116 women on ERT and 172 women not on ERT.
  • Utilized the Benton Visual Retention Test (BVRT) to measure short-term visual memory and related skills.

Main Results:

  • Women receiving ERT made fewer errors on the BVRT compared to those not on ERT.
  • ERT showed a potential protective effect against age-related decline in BVRT performance in a subgroup analysis.
  • Findings indicate a positive association between ERT and memory function.

Conclusions:

  • Estrogen replacement therapy may help prevent memory decline in nondemented postmenopausal women.
  • Estrogen appears to play a beneficial role in maintaining cognitive function during aging.
  • Further research supports estrogen's positive impact on cognitive health in older women.
