IMProving Executive Function Study

Summary

This is a double-blind, placebo-controlled, crossover study testing whether Vyvanse (lisdexamfetamine; LDX) improves executive functioning (EF) in 100 postmenopausal women who report onset of EF difficulties after oophorectomy. This study involves magnetic resonance imaging (MRI) to see how LDX affects brain chemistry while undergoing two 6-week trials of the study drug and placebo capsules. UPDATE: We have recently updated this protocol (09/2020) to offer a remote version of the study that can be completed entirely from the participant's home. This alternate version of the study eliminates travel, the MRI, and blood draws.
