Abstract

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation intervention that modifies cortical excitability according to the stimulation parameters. Preclinical and clinical studies in healthy volunteers suggest that tDCS induces neuroplastic alterations of cortical excitability, which might explain its clinical effects in major depressive disorder (MDD). We therefore examined whether tDCS, as compared to the antidepressant sertraline, increases plasma brain-derived neurotrophic factor (BDNF) levels, a neurotrophin associated with neuroplasticity. Patients (n=73) with major depressive disorder were randomized to active/sham tDCS and sertraline/placebo (four groups) in this 6-week, double-blind, placebo-controlled trial. We measured BDNF plasma levels at baseline and endpoint, observing no significant changes of BDNF levels after treatment. In addition, no significant changes were observed in responders and non-responders as well as no relationships between BDNF levels and clinical and psychopathological variables related to depression. Thus, in one of the few placebo-controlled trials evaluating BDNF changes over an antidepressant treatment course, we did not observe BDNF increase regardless of clinical improvement in depressed patients. Regarding tDCS, BDNF plasma levels might not be a good candidate biomarker to evaluate depression improvement or be a predictor of response in patients treated with tDCS, as our results showed that BDNF increase was not necessary to induce clinical response. Finally, our findings do not support a relationship between BDNF and improvement of depression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
