Brief Summary:
This study seeks to assess the effects of lisdexamfetamine (trademark name: Vyvanse; LDX) on executive function and prefrontal cortex activation in menopausal women ages 45-57, who report subjective cognitive difficulties. This protocol will recruit women from Dr. Epperson's ongoing study, Protocol #812470, to examine the impact of LDX on brain activation during performance of cognitive tasks specifically probing prefrontal cortex function.

Primary Outcome Measures :
  1. Percent Change in Blood Oxygen Level Dependent (BOLD) Signal [ Time Frame: 10 weeks ]
    Blood-oxygen-level dependent contrast imaging, or BOLD-contrast imaging, is a method used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which are found to be active at any given time. BOLD signals were compared from baseline, first intervention and second intervention.

Secondary Outcome Measures :
  1. Change in BADDS Total Score [ Time Frame: 10 weeks ]
    The total BADDS ranged from 0-120 with higher scores meaning greater problems with memory, attention and focus. Difference in BADDS score from Baseline to End of Treatment for each study Arm was calculated.
