Borderline personality disorder is a clinically important psychiatric diagnosis that is distinct from major depressive, bipolar and posttraumatic stress disorders, despite the overlapping symptoms. The diagnosis is mainly clinical and must follow the DMS 5 (or ICD 10) characteristics. The most common age at first presentation is in late adolescence, but the disorder frequently can be stay as misdiagnosed. Our study is concerned to QEEG characteristics, as well as coherence in borderline patients compared with healthy group, matched by number, gender and age and selected randomly. Our obtained results showed that electrophysiological characteristics for borderlines are fairly without statistical differences, except in low bands (delta and theta), which showed significantly lower frequencies and coherence compared to a healthy group. Future research in this filed with more patients is highly recommended.
