FIQUER, Juliana Teixeira et al. Affective changes in depressed patients treated with Transcranial Direct Current Stimulation. Temas psicol. [online]. 2007, vol.15, n.2, pp.149-159. ISSN 1413-389X.

The present study evaluated, through self-reports of positive affects, of negative affects and of life satisfaction, the therapeutic effects of anodal Transcranial Direct Current Stimulation (TDCS) on depressed patients. Thirty one patients with major depression participated on this study. They were distributed in two groups: Active Group (n=21) treated with ten sessions of anodal 2mA TDCS applied in the left dorsolateral prefrontal cortex and the Control Group (n=10) treated with ten sessions of TDCS placebo. Both groups answered a Brief Affect Scale and evaluated their life satisfaction through a Scale of Schematic Faces before and after the treatment. Patients of the Active Group presented an increase of positive affects, a reduction of negative affects and an increase of their life satisfaction. These findings point to the presence of bidimensional affective alterations in depression and to the therapeutic potential of the TDCS in the readjustment of positive and negative affects.
