Abstract | Reduced cognition is often reported by breast cancer patients and survivors, but the mechanisms for this decline are yet to be determined. We compared the differences in cerebrovascular function and cognition in breast cancer survivors (n = 15) and cancer-free women (n = 15) matched by age and body mass index. Participants undertook anthropometric, mood, cardiovascular, exercise performance, strength, cerebrovascular, and cognitive measurements. Transcranial Doppler ultrasound was used to measure the cerebrovascular responsiveness (CVR) to physiological (hypercapnia; 5% carbon dioxide) and psychological stimuli. Breast cancer survivors had a lower CVR to hypercapnia (21.5 ± 12.8 vs 66.0 ± 20.9%, P < 0.001), CVR to cognitive stimuli (15.1 ± 1.5 vs 23.7 ± 9.0%, P < 0.001) and total composite cognitive score (100 ± 12 vs. 113 ± 7, P = 0.003) than cancer-free women. These parameters remained statistically different between the groups following adjustments for covariates using an analysis of co-variance. We observed significant correlations between multiple measures and exercise capacity the only variable positively correlated to all primary measures (CVR to hypercapnia, r = 0.492, P = 0.007; CVR to cognitive stimuli r = 0.555, P = 0.003; and total composite cognitive score, r = 0.625, P < 0.001). In this study, breast cancer survivors had lower cerebrovascular and cognitive function than age-matched cancer-free women, which may be attributable to the effects of cancer and cancer treatment on brain health. |
