Summary
Childhood cognitive function is linked to the timing of natural menopause. Ovarian steroids may influence cognitive abilities throughout a woman's life, impacting both reproductive aging and neural development.
Area of Science:
- Neuroscience
- Reproductive Endocrinology
- Developmental Psychology
Background:
- Ovarian steroids are known to influence reproductive aging and neural development.
- Understanding the relationship between menopause and cognitive function is crucial for women's health.
Purpose of the Study:
- To investigate the association between menopause timing and lifetime cognitive function.
- To examine the influence of ovarian steroids on cognitive development and aging.
Main Methods:
- Prospective birth cohort study of 1,572 women (British 1946 birth cohort).
- Cognitive function assessed at multiple ages (8, 11, 15, 26, 43 years).
- Menopause timing analyzed using Cox proportional hazard models and competing risks analysis, accounting for hysterectomy, oophorectomy, and hormone replacement therapy (HRT).
Main Results:
- Higher cognitive scores were significantly associated with later menopause.
- This association was most pronounced in childhood cognitive function.
- The findings were independent of potential confounders like social background, physical development, education, parity, smoking, and alcohol consumption.
Conclusions:
- Childhood cognitive function is demonstrably related to the timing of natural menopause.
- Ovarian steroids likely play a role across the lifespan, influencing both cognitive function and reproductive aging.
