Summary
The purpose of this 6-week, double-blind, placebo-controlled, crossover study is to explore new treatment options for people with depression who have high inflammation and anhedonia. Thirty-five male and female participants with depression, between the ages of 25-55 years of age, will be randomized to two study tracks (A and B) to receive both placebo and three doses of L-DOPA, given in different orders. Increases or decreases in each dose will occur gradually over 6 weeks of the study. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing and functional MRI (fMRI) scans as part of the study. The total length of participation is about 2 months.
