Many of the studies exploring dopamine (DA) function in depression have produced inconsistent findings. Contributors to this inconsistency include the diagnostic heterogeneity of major depressive disorder (MDD); failure to control for age, bipolar disorder, and comorbid diagnoses; and variation in patient medication treatment status at the time of the study. Despite this variability, there is now a convergence of data from animal models, genetics, neuroimaging, and human clinical trials that strengthens the case for DA dysfunction in the pathophysiology of major depression, at least in a significant subgroup of patients. This chapter comprehensively reviews the current evidence, with subsequent recommendations for future studies of dopaminergic signaling in depression and its treatment.
