“…The most notable results in our study are the improvements on ADHD-RS scores following tRNS and EF training relative to baseline and to tDCS and EF training. These promising results on the tRNS protocol support those of several studies in healthy young adults (Terney et al, 2008;Fertonani et al, 2011;Cappelletti et al, 2013;Snowball et al, 2013;Pasqualotto, 2016;Popescu et al, 2016;Brem et al, 2018;Frank et al, 2018;Brevet-Aeby et al, 2019;Peña et al, 2019), including a recent meta-analysis (Simonsmeier et al, 2018). Importantly, the results showed a further significant improvement 7 days after the end of the treatment, mirroring a similar lasting tRNS effect in previous studies on healthy adults (Cappelletti et al, 2013;Snowball et al, 2013;Pasqualotto, 2016;Frank et al, 2018;Brevet-Aeby et al, 2019).…”

Various methods have been attempted to effectively ameliorate psychiatric and neurological conditions in children and adults. One of the attractive ideas is to develop interventions to create a lasting, rather than only an immediate, effect. Neurostimulation has been shown to yield long-term effect when combined with cognitive training in healthy young adults. We examined whether such approach could benefit children with attention deficit hyperactivity disorder (ADHD), the most common neurodevelopmental disorder in childhood. We used a randomized double-blind active-controlled crossover study of 19 unmedicated children (aged 7-12 years old) with attention deficit hyperactivity disorder, who received either transcranial direct current stimulation or random noise stimulation while completing five-day executive functions training, which includes working memory, cognitive flexibility, and inhibition tasks. Both stimulation protocols have previously shown potential for inducing lasting benefits in adults, while transcranial direct current stimulation was examined in multiple attention deficit hyperactivity disorder studies and has been highlighted as a promising method for treating neuropsychological deficits. For our primary outcome, transcranial random noise stimulation yielded a clinical improvement as indicated by the reduced attention deficit hyperactivity disorder rating scale score from baseline, and in comparison to the changes observed in transcranial direct current stimulation. Moreover, the effect of brain stimulation one week after completion of treatment yielded further improvement, suggesting a neuroplasticity-related effect. Finally, transcranial random noise stimulation improved working memory compared to transcranial direct current stimulation, and a larger transcranial random noise stimulation effect on attention deficit hyperactivity disorder rating scale was predicted for those patients who showed the greatest improvement in working memory. Our results provide a promising direction toward a novel intervention in attention deficit hyperactivity disorder, which is shown to have a lasting effect via the modulating of neuroplasticity, rather than a merely immediate effect as was shown for in previous medical interventions.

“…Also considering neurodevelopmental studies, the accumulation of arithmetic proficiency may be accompanied by a shift from broad prefrontal to precise parietal activations (Zamarian et al 2009). In this line, both frontal and parietal excitatory tRNS generated greater speed improvements over the course of an experiment in subtraction verifications, but not in word classifications (Pasqualotto 2016).…”

“…In cognitive tasks, mixed results were obtained and some studies report on the lack of performance modulations in working memory tasks (Mulquiney et al 2011;Holmes et al 2016). However, numerous studies also report on effective performance and learning modulations by tRNS in numerical tasks and trainings (Cappelletti et al 2013;Snowball et al 2013;Pasqualotto 2016;Popescu et al 2016). Little direct behavioral outcome comparisons between the two techniques exist to date.…”

Cognitive Enhancement of Numerical and Arithmetic Capabilities: a Mini-Review of Available Transcranial Electric Stimulation Studies

Arithmetic capabilities are complex cognitive skills essential for handling requirements of the modern world. At the same time, educational institutions are challenged with mathrelated problems, e.g., developmental dyscalculia and math anxiety, and also with less severe difficulties of arithmetic understanding. Thus, non-invasive techniques for cognitive enhancement have attracted researchers' and practitioners' interest in the fields of education, psychology, and neuroscience. Particularly, studies employing transcranial electric stimulation (tES) in arithmetic learning, problem solving, and performance in numerical tasks and operations have shaped an optimistic perspective of cognitive enhancement in these domains, building on the fronto-parietal correlates of healthy and deficient arithmetic performance and learning. However, the heterogeneity of stimulation approaches in numerical cognition researchwith different electrode montages, stimulation protocols, tasks, outcomes, and combinations thereof-may also showcase a variety of parameters relevant more generally to the cognitive domain. Here, we present a short overview of the different tES approaches to enhance numerical and arithmetic capabilities in performance and training within the general framework of cognitive enhancement. We conclude that performance and training gains can be obtained from different strategical tES configurations, but more standardization, better translation between neurodevelopmental perspectives and tES principles, as well as pre-registered and controlled studies in critical populations are needed.

“…Numerous studies have shown that transcranial electrical stimulation (tES) can modulate a wide-range of behavioral processes (Coffman et al, 2014; Harty et al, 2014; Sarkar et al, 2014; Pasqualotto, 2016), and ameliorate deficits in several neuropsychiatric disorders (for reviews see Kekic et al, 2016; Lefaucheur et al, 2017). These promising outcomes, in conjunction with the fact that the approach is safe and inexpensive, have generated enthusiasm for its viability as both an investigative and neuroenhancement tool.…”
