Adjunctive Treatment With L-methylfolate for Treatment-Resistant Generalized Anxiety Disorder: a Pilot Study

Summary

The goal of this feasibility study is to determine the tolerability and safety of add on treatment with L-methylfolate in patients with treatment-resistant generalized anxiety disorder (GAD). The primary objective is to monitor for side effects and other risks associated with the treatment. Secondary objectives are to compare the severity of symptoms, serum levels of folate, vitamin B12, C-reactive protein, homocysteine, tumor necrosis factor alpha and interleukin 6 before and after treatment. Participants will continue with their usual treatment for GAD and receive add on treatment with L-methylfolate 15 mg per day for 8 weeks. All participants will receive the same intervention.
