Can transcranial direct current stimulation (tDCS) improve impulsivity in healthy and psychiatric adult populations? A systematic review

Publication date: Available online 9 November 2019Source: Progress in Neuro-Psychopharmacology and Biological PsychiatryAuthor(s): JulianaTeti Mayer, Gilles Chopard, Magali Nicolier, Damien Gabriel, Caroline Masse, Julie Giustiniani, Pierre Vandel, Emmanuel Haffen, Djamila BennabiAbstractImpulsivity is a multidimensional phenomenon that remains hard to define. It compounds the core pathological construct of many neuropsychiatric illnesses, and despite its close relation to suicide risk, it currently has no specific treatment. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique whose application results in cognitive function improvement, both in healthy and psychiatric populations. Following PRISMA recommendations, a systematic review of the literature concerning tDCS's effects on impulsive behaviour was performed using the PubMed database. The research was based on the combination of the keyword ‘tDCS’ with ‘impulsivity’, ‘response inhibition’, ‘risk-taking’, ‘planning’, ‘delay discounting’ or ‘craving’. The initial search yielded 309 articles, 92 of which were included. Seventy-four papers demonstrated improvement in task performance related to impulsivity in both healthy and clinical adult populations. However, results were often inconsistent. The conditions associated with improvement, such as tDCS parameters and other aspects that may influence tDCS...

Authors: Singh AK, Singh R Abstract BACKGROUND: Lorcaserin is a novel, selective 5-hydroxytryptamine 2C serotonin receptor agonist, approved for the treatment of obesity. Several phase 3 randomized controlled trials (RCTs) trials have shown a significant reduction in body weight with lorcaserin. RESEARCH DESIGN AND METHODS: We systematically searched the database of PubMed, Embase, The Cochrane Library and up to July 31, 2019 and retrieved all the studies conducted with lorcaserin for ≥ 1-year that have explicitly reported the efficacy and safety outcomes versus placebo.

Conclusion: Risk factors for physical fighting among adolescents in South Asia seem to corroborate with previously-identified risk factors using samples in high-income countries, while protective factors seemed to differ. More research needs to be conducted to understand why certain factors do not have the same protective effect among South Asian adolescents. Aim: The aim of this study was to examine demographic and contextual factors associated with physical fighting among a nationally representative sample in a rapidly developing South Asian context.
