Transcranial Stimulation Has Potential as Add-On Therapy For Bipolar Depression

MedicalResearch.com Interview with:

Yokoi and Sumiyoshi. 2015 tDCS administration at National Center of Neurology and Psychiatry Hospital. A subject (front) sits on a sofa relaxed, and a researcher (behind) controls the tDCS device (a). In this picture, anodal (b) and cathodal (c) electrodes with 35-cm2 size are put on F3 and right supraorbital region, respectively. We use a head strap (d) for convenience and reproducibility, and also use a rubber band (e) for reducing resistance

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In this study, our aim was to evaluate the safety and efficacy of transcranial direct current stimulation (tDCS) as an add-on treatment for patients with bipolar depression. There are a only few treatment alternatives for bipolar depression, which often have important side effects. Thus, we wanted to evaluate the efficacy of this non-pharmacological treatment.

We found that active vs. sham tDCS effected greater response and remission for patients with bipolar depression. The frequency of adverse effects was similar, including treatment-emergent affective switches. However, higher rates of skin redness were observed in the active group.

MedicalResearch.com: What should clinicians and patients take away from your report?

Response: In this preliminary study, tDCS showed efficacy and safety for treating bipolar depression. It can be a potential add-on treatment for these patients.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Response: The sample size was small and therefore our results were preliminary. They should be replicated in a larger sample. Also, the trial only lasted 6 weeks, so future research could also explore the effects of tDCS in the maintenance phase of bipolar depression.
