Surgical menopause may cause short-term cognitive impairment, particularly in verbal memory, unlike natural menopause. Hormone therapy shows limited cognitive benefits, especially in older women.

Area of Science:

  • Reproductive Endocrinology
  • Neuroscience
  • Gerontology

Background:

  • Menopause, both natural and surgical, involves estrogen loss, but hormonal and demographic factors differ.
  • Understanding cognitive aging differences between natural and surgical menopause is crucial.

Purpose of the Study:

  • To review evidence on cognitive aging consequences of premature estrogen cessation after surgical menopause.
  • To compare these consequences with those of natural menopause.
  • To assess the relevance of estrogen-containing hormone therapy.

Main Methods:

  • Systematic review of evidence-based research.
  • Inclusion of randomized clinical trials of hormone therapy.
  • Focus on cognitive outcomes, specifically episodic memory measures.

Main Results:

  • Surgical menopause may be linked to verbal episodic memory impairment, based on small, short-term estrogen trials.
  • Natural menopause transition shows no substantial cognitive changes.
  • Hormone therapy initiation in perimenopause/early postmenopause lacks consistent short-term cognitive benefit/harm evidence.
  • Late postmenopause hormone therapy initiation shows no cognitive benefit.

Conclusions:

  • Further research is needed on long-term cognitive effects of surgical menopause and hormone therapy.
  • A potential short-term cognitive benefit of estrogen therapy post-hysterectomy/oophorectomy may exist but data are limited.
  • Older postmenopausal women should not start hormone therapy for cognitive enhancement.
