Egan, K., and C. Gleason. “Longer Duration of Hormonal Contraceptive Use Predicts Better Cognitive Outcomes Later in Life.”. Journal of women’s Health (2002), Vol. 21, no. 12, 2012, pp. 1259-66.
The cognitive effects of postmenopausal hormone therapy (HT) have been studied extensively, but little is known about the relationship between premenopausal hormone use and cognition. Hormonal contraceptive use vs. nonuse may be a potential factor influencing cognitive processes in midlife. The aim of this study is to explore the effect of modification of hormone milieu through use of hormonal contraception in premenopausal women and midlife cognitive function.
