The Effect of Forehead Cortex Electric Current Stimulation on Inhibitory Control and Working Memory in Children with Attention Deficit and Hyperactivity Disorder

This study aimed at determining the effect of forehead cortex electric current stimulation on inhibitory control and working memory in people with attention deficit and hyperactivity disorder (ADHD), using TDCS device. The method used was quasiexperimental research with pretestposttest control group design. The participants were 24 children with attention deficit and hyperactivity disorder aged 711 who referred to Baqiyatallah Hospital in 1397. Children were randomly divided into experimental (n = 12) and control (n = 12) groups. The experimental group was intervened in 10 sessions, 3 times a week, and each session was 20 minutes. Assessments were performed in 3 steps, a day before the intervention, and a day after the intervention ended, and finally at the followup phase, two months after the intervention was accomplished. Go/no Go and Nback tests were used to evaluate inhibitory control and working memory, respectively.  A repeated measurement method was applied to analyze the data. Findings revealed that brain electric stimulation program improves working memory and inhibitory control in children with attention deficit hyperactivity disorder. Therefore, brain electric stimulation program can be used to enhance the working memory and inhibitory control of children with attention deficit hyperactivity disorder.
