Abstract Objective The majority of women experience vasomotor symptoms (VMS) during the menopausal transition. Whether self-reported VMS are associated with cognitive test performance later in life remains unclear. The goal of this study was to determine whether a greater burden of VMS is associated with poor later-life cognition. Methods The Wisconsin Longitudinal Study is a prospective study of randomly selected Wisconsin high school graduates of the class of 1957. At ages 65 and 72, a random subset of participants completed six cognitive tests, including similarities, letter and category fluency, immediate and delayed word recall, and digit ordering. Nested regression models were used to examine the association between extent of VMS, assessed at age 54, and baseline cognition at 65, adjusting for early-life socioeconomic status, women’s reproductive health variables, intelligence quotient, and midlife income. This series of models was also used to examine the association between VMS and change in cognition score from age 65 to 72. In sensitivity analyses, models were repeated in a sample using multiple imputation for missing covariates. Results Of the 5,326 women enrolled, 874 had data onVMS, covariates, and all cognitive tests. In an unadjusted model, higher VMS were associated with a lower similarities score (b = -0.09 95% CI -0.16 to -0.02) at age 65 but no other cognitive tests. In adjusted models, VMS were not related to cognition at age 65 or change in cognition. Results remained similar with multiple imputation. Conclusions Our study does not support a relationship between self-reported VMS and cognition later in life.
