Transcranial direct current stimulation as early augmentation in adolescent obsessive compulsive disorder: A pilot proof-of-concept randomized control trial.

Abstract

Background: Transcranial direct current stimulation (tDCS) is proven to be safe in treating various neurological conditions in children and adolescents. It is also an effective method in the treatment of OCD in adults.

Aim: To assess the safety and efficacy of tDCS as an add-on therapy in drug-naive adolescents with OCD.

Methods: We studied drug-naïve adolescents with OCD, using a Children's Yale-Brown obsessive-compulsive scale (CY-BOCS) scale to assess their condition. Both active and sham groups were given fluoxetine, and we applied cathode and anode over the supplementary motor area and deltoid for 20 min in 10 sessions. Reassessment occurred at 2, 6, and 12 wk using CY-BOCS.

Results: Eighteen adolescents completed the study (10-active, 8-sham group). CY-BOCS scores from baseline to 12 wk reduced significantly in both groups but change at baseline to 2 wk was significant in the active group only. The mean change at 2 wk was more in the active group (11.8 ± 7.77 vs 5.25 ± 2.22, P = 0.056). Adverse effects between the groups were comparable.

Conclusion: tDCS is safe and well tolerated for the treatment of OCD in adolescents. However, there is a need for further studies with a larger sample population to confirm the effectiveness of tDCS as early augmentation in OCD in this population.
