Oxidative status and prolidase activities in generalized anxiety disorder.

•We studied oxidative stress and prolidase activity in generalized anxiety disorder.•Generalized anxiety disorder patients have higher total oxidant status levels.•Generalized anxiety disorder patients have higher oxidative stres index levels.•Prolidase activity is higher in patients with generalized anxiety disorder.•Prolidase is promising to be a follow-up marker for generalized anxiety disorder.
