Objectives: Children with attention deficit/hyperactivity disorder (ADHD) have been shown to display more inhibitory deficits and executive function deficits. This study addresses treatment effects of neurofeedback trainings on executive function by comparing the results of neuropsychological test at pre and post-training Methods: 15children with ADHD, aged 6 to 14 years, participated in the study. The NF treatment consisted of slow cortical potential (SCP) training and theses sessions took place once a week. Children performed 20 sessions of NF training within 6 months. Pre-training and post-training assessment encompassed continuous performance test, Stroop test children’s color trails test 1&2 and Wisconsin card sorting test. Results: Patients receiving NF improved significantly on the visual commission error, SD of response time in continuous performance test; total errors in Wisconsin card sorting test. But there are no significant improvement in Stroop test and children’s color trails test 1&2. Discussion: NF of SCP training improves the self-regulatory capacities and impulsivity in ADHD patient, especially impulsivity at visual stimulation task. This study suggest that clinical efficacy of NF on executive function in ADHD.
