Outcome Measures
Primary Outcomes (1)
Functional Magnetic Resonance Imaging (fMRI) Changes in Response to Estrogen and Aging - Dorsolateral Pre-frontal Cortex (DLPFC)
Change in extracted beta coefficients of the blood oxygen level dependent (BOLD) signal response to a cognitive task (N-back) in the DLPFC (x,y,z coordinates = -34 44 16) from baseline to 1 month as a function of aging and estrogen (young vs older and estrogen vs placebo). A positive change indicates an increase in oxygen utilization (inferring increased neuronal functioning) between baseline and treatment during the cognitive task, while a negative change indicates a decrease in oxygen utilization between baseline and treatment during the cognitive task.
baseline to 1 month
Study Arms (4)
Young postmenopausal women - estrogen
EXPERIMENTALtransdermal estrogen patch OR estradiol oral capsule for 1 month
Older postmenopausal women - estrogen
EXPERIMENTALtransdermal estrogen patch OR estradiol oral capsule for 1 month
Young postmenopausal women - placebo
PLACEBO COMPARATORtransdermal placebo patch for 1 month or placebo oral capsule for 1 month
Older postmenopausal women - placebo
PLACEBO COMPARATORtransdermal placebo patch for 1 month or placebo oral capsule for 1 month
Interventions
1 oral capsule (1 mg estradiol) administered daily for one month
transdermal estrogen patch (50 mcg/day) for one month
transdermal placebo patch with patch change every 84 hr for one month
placebo oral capsule administered daily for one month.
