Study Design

Observational model case control
Time perspective cross-sectional

Primary Outcomes

To quantify insulin-mediated glucose uptake as assessed by the SSPG concentration in patients with depression and compare the values to those previously obtained in a healthy age-matched control population
time frame: Within 3 hours of initial infusion

Secondary Outcomes

To examine the association between insulin resistance and cognitive performance and clinical course of depression in patients with depression
time frame: 1 wk
