Randomized Controlled Trial
Transcranial direct current stimulation in treatment resistant depression: a randomized double-blind, placebo-controlled study.
Anodal transcranial direct current stimulation (tDCS) of the prefrontal cortex has been proposed as therapeutic intervention in major depression. According to clinical needs, this study addresses the question whether tDCS is effective in treatment resistant major depressive episodes. ⋯ Anodal tDCS, applied for 2 weeks, was not superior to placebo treatment in patients with treatment resistant depression. However, secondary outcome measures are pointing to a positive effect of tDCS on emotions. Therefore, modified and improved tDCS protocols should be carried out in controlled pilot trials to develop tDCS towards an efficacious antidepressant intervention in therapy-resistant depression.
