[Transcranial direct current stimulation for depressive disorders]. Nervenarzt. 2015 Nov 18; Authors: Aust S, Palm U, Padberg F, Bajbouj M Abstract Major depressive disorders are one of the most prevalent psychiatric disorders worldwide but approximately 20-30 % of patients do not respond to standard guideline conform treatment. Recent neuroimaging studies in depressive patients revealed altered activation patterns in prefrontal brain areas and that successful cognitive behavioral therapy and psychopharmacological interventions are associated with a reversal of these neural alterations. Therefore, a direct modulation of prefrontal brain activation by non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS) seems to be a promising and innovative approach for the treatment of depressive disorders. In addition, recent neuropsychological findings indicated an augmentation of positive tDCS effects by simultaneous external activation of the stimulated brain area, for example by cognitive training tasks. Based on these findings, the possibility to augment cognitive-emotional learning processes during cognitive behavioral therapy by simultaneous tDCS to increase antidepressive therapeutic effects is discussed in this article.
