- Efficacy and acceptability of transcranial direct current stimulation (tDCS) for major depressive disorder: An individual patient data meta-analysis(2020) MOFFA, Adriano H.; MARTIN, Donel; ALONZO, Angelo; BENNABI, Djamila; BLUMBERGER, Daniel M.; BENSENOR, Isabela M.; DASKALAKIS, Zafiris; FREGNI, Felipe; HAFFEN, Emmanuel; LISANBY, Sarah H.; PADBERG, Frank; PALM, Ulrich; RAZZA, Lais B.; SAMPAIO-JR, Bernardo; LOO, Colleen; BRUNONI, Andre R.We evaluated the efficacy and acceptability of transcranial direct current stimulation (tDCS) for treating acute depressive episodes using individual patient data that provide more precise estimates than aggregate data metaanalysis. A systematic review of placebo-controlled trials on tDCS as only intervention was conducted until December-2018. Data from each study was collated to estimate odds ratio (OR) and number needed to treat (NNT) of response and remission, and depression improvement. Endpoints were pre-determined. Nine eligible studies (572 participants), presenting moderate/high certainty of evidence, were included. Active tDCS was significantly superior to sham for response (30.9% vs. 18.9% respectively; OR = 1.96, 95%CI [1.30-2.95], NNT = 9), remission (19.9% vs. 11.7%, OR = 1.94 [1.19-3.16], NNT = 13) and depression improvement (effect size of beta = 0.31, [0.15-0.47]). Moreover, continuous clinical improvement was observed even after the end of acute tDCS treatment. There were no differences in all-cause discontinuation rates and no predictors of response were identified. To conclude, active tDCS was statistically superior to sham in all outcomes, although its clinical effects were moderate.
- Transcranial direct current stimulation in psychiatric disorders(2015) TORTELLA, Gabriel; CASATI, Roberta; APARICIO, Luana V. M.; MANTOVANI, Antonio; SENCO, Natasha; D'URSO, Giordano; BRUNELIN, Jerome; GUARIENTI, Fabiana; SELINGARDI, Priscila Mara Lorencini; MUSZKAT, Debora; PEREIRA JUNIOR, Bernardo de Sampaio; VALIENGO, Leandro; MOFFA, Adriano H.; SIMIS, Marcel; BORRIONE, Lucas; BRUNONI, Andre R.The interest in non-invasive brain stimulation techniques is increasing in recent years. Among these techniques, transcranial direct current stimulation (tDCS) has been the subject of great interest among researchers because of its easiness to use, low cost, benign profile of side effects and encouraging results of research in the field. This interest has generated several studies and randomized clinical trials, particularly in psychiatry. In this review, we provide a summary of the development of the technique and its mechanism of action as well as a review of the methodological aspects of randomized clinical trials in psychiatry, including studies in affective disorders, schizophrenia, obsessive compulsive disorder, child psychiatry and substance use disorder. Finally, we provide an overview of tDCS use in cognitive enhancement as well as a discussion regarding its clinical use and regulatory and ethical issues. Although many promising results regarding tDCS efficacy were described, the total number of studies is still low, highlighting the need of further studies aiming to replicate these findings in larger samples as to provide a definite picture regarding tDCS efficacy in psychiatry.
