Systemic Inflammation Related to Mood Disorders


About this study

The overall goal is to better understand the underlying pathophysiology of mood disorders and bipolar disorders in particular. We aim to investigate whether the subclinical atherosclerotic and inflammatory markers differ between patients with bipolar disorder, major depressive disorder, and psychiatric non-mood disorders and healthy subjects.
