Abstract
Aim:Attention deficit hyperactivity disorder is a common disorder in children characterized by inattention and impulsivity. The aim of this study was to compare the effectiveness of transcranial direct current stimulation in the dorso-lateral prefrontal and temporal- parietal regions on theory of mind in children with ADHD. Method:This research was semi-experimental and its design was pre-test, post-test with control and follow-up groups. The statistical population included students with ADHD in Tehran, among whom 45 people with primary diagnosis of ADHD were selected using the available sampling method and were randomly divided into three groups of 15 people with transcranial direct electrical stimulation in the dorso-lateral Prefrontal region, transcranial direct current stimulation of the temporal-parietal region and the control group were included. In this research, transcranial direct current stimulation was used in the twomentioned areas in 12 sessions with a current intensity of 1 milliamp and a duration of 20 minutes in two groups for children. To measure the theory of mind, the Strainman questionnaire and the mind reading test through the eyes of Baron Cohen were used.
Results:Variance analysis test was performed to compare three groups in theory of mind and in pre-test, post-test and follow-up stages. Both interventions were significant at 0.01 level and effective on theory of mind. Stimulation of the temporal-parietal region increased theory of mind, but the effectiveness of transcranial direct current stimulation in the dorso-lateral prefrontal region was greater on theory of mind.
Conclusion: According to the findings of the research, these interventions have an effect
