Introduction: The prevalence of borderline personality disorder is more than other type of personality disorders. It has been shown that there are some neurological deficits in patients with borderline personality disorder such as cognitive inhibition and self-injury, but the few studies aimed to decrease this deficit have been conducted. The purpose of this study was to investigate the effectiveness of emotional working memory training on the EEG asymmetry index in the beta band between two hemispheres in people with borderline personality disorder. Materials and Methods: The method of the current study was experimental and its design was pretest-posttest with the control group. All students of the University of Mohaghegh Ardebili with borderline personality disorder in 96-97 academic years comprised the statistical population of this study. Forty people selected by screening method via scale of borderline personality disorder trait and the structural clinical interview for mental disorders (SCID-II) and assigned to two experimental and control groups. The experimental group received 10 sessions of emotional working memory training, but no intervention was provided for the control group. The EEG device was used to record the electrical activity of the brain from the frontal lobe (Fp1, Fp2, F3, F4, F7, F8). Results: The results showed that the mean scores of the interhemispheric beta asymmetry have increased in the experimental group compared to the control group at the post-test stage. The emotional working memory training can lead to increased interhemispheric beta asymmetry. This intervention can increase the beta asymmetry by enhancing the beta wave in left hemisphere rather than right. Conclusion: the emotional working memory training can be the main axis to improve interhemispheric beta asymmetry in people with borderline personality disorder.
