The effect of transcranial direct current stimulation (tDCS) on improving working memory performance in children with mathematical disorder

The main aim of the present study was investigating the effect of tDCS on improving working memory of children with mathematical disorder. To do so, 20 elementary students with math disorder were selected from Tehran clinics’ clients using purposeful sampling. For assessing working memory, N-back test was conducted by all subjects. Subjects were divided into two groups; 10 subjects received tDCS and rest of them, the control group, didn’t receive it. Training sessions were conducted for 10 days: each day one session-10 minutes with an intensity of 1 mA. Data were analyzed using Analysis of Covariance (ANCOVA). The results showed that effect of tDCS on working memory performance have been effective. The results of this study showed that tDCS can improve working memory performance in children with mathematical disorder
