Abstract

Abstract: Objective: The aim of this study was to determine the prevalence and associated factors of mild cognitive impairment (MCI) and subtypes, amnestic MCI (aMCI) and non-amnestic MCI (naMCI), in women with surgical menopause. Methods: We obtained the database containing information for 200 women with surgical menopause from our previous study. The Montreal Cognitive Assessment – total score, the Montreal Cognitive Assessment – memory index score (MoCA-MIS) and their age, years since menopause, education, medical and surgical history, hormone therapy use, exercise, sleep duration, alcohol use, smoking and family history of dementia were obtained. All participants without the MoCA-MIS were excluded. Result: The average age of the 164 participants was 56.3 ± 6.9 years. The prevalence of MCI, aMCI and naMCI was 43.3%, 9.8% and 33.5%, respectively. The duration of education reduced MCI for 93% (95% confidence interval 0.03–0.20) of the women. In late postmenopause, hormone therapy >10 years showed 47% lower prevalence of MCI (age-adjusted odds ratio = 0.53, 95% confidence interval 0.22–1.28). Finally, length of education was the only independent factor associated with MCI and its subtypes. Conclusion: We found a high prevalence of MCI and the non-amnestic subtype in women with surgical menopause. Further study is needed to clarify the long-term effects of surgical menopause on cognitive function.
