The aim of this study was The Effect of Brain cognitive interventions on executive functions in children with attention deficit hyperactivity disorder.Method: The method of this research was semi-experimental and applied in terms of its purpose, which was done using a pre-test-post-test design with control group.30 children with attention deficit hyperactivity disorder participated in this study. At the pretest stage, Selected Attention Test was taken by Strop Effect on Psychological Refractory Period test. The participants were randomly divided into experimental and control groups of 15.The experimental group received Brain cognitive interventions for 12 sessions per hour and for 4 weeks (3 sessions per week).During this period, no intervention was performed in the control group. After the end of the intervention period, a post-test was taken. Data were analyzed by covariance analysis using SPSS_22 software. Results: The results showed that Brain cognitive interventions is affected by focused Selective Attention (P <0.001) and divided (P <0.002).Conclusion: In a general conclusion, it can be argued that presentation of Brain cognitive interventions could improve executive functions such as focused selective attention and divided selected attention in children with attention deficit hyperactivity disorder.
