Trial Outcomes & Findings for Aging and Estrogen on Cortical Function (NCT NCT01268046)

NCT ID: NCT01268046

Last Updated: 2018-08-22

Results Overview

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.

PRIMARY outcome

Timeframe: baseline to 1 month

Population: all young and older postmenopausal women who completed one month of placebo or estrogen and in whom structural and functional MRI data were of significant quality for analysis.

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.
