Key result
Cerebrovascular reactivity, measured by the breath-holding index, was significantly reduced in postmenopausal women (0.89±0.3) compared to premenopausal women (1.59±0.3; P < 0.0001).
Why the study?
Does postmenopausal status reduce cerebrovascular reactivity in healthy women compared to premenopausal women and age-matched men?
Does postmenopausal status reduce cerebrovascular reactivity in healthy women compared to premenopausal women and age-matched men?
Postmenopausal women exhibit significantly reduced cerebrovascular reactivity compared to premenopausal women and age-matched men, suggesting that hormonal changes rather than aging alone impair cerebral hemodynamics.

Postmenopausal status may heighten cerebrovascular vulnerability; leaves open causal mechanisms and need for prospective trials before practice change.
Matteis et al. (1998) studied this question. Cerebrovascular reactivity, measured by the breath-holding index, was significantly reduced in postmenopausal women (0.89±0.3) compared to premenopausal women (1.59±0.3; P < 0.0001).
