Brain scans reveal why social rejection hurts more in BPD
NCT ID NCT07428200
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study uses EEG brain scans to understand how people with borderline personality disorder (BPD) process social rejection. Researchers will measure brain activity while participants play a virtual ball-tossing game designed to make them feel left out. The goal is to identify differences in the brain's pain network that may explain why social rejection feels more intense for those with BPD. Findings could lead to new ways to help reduce social pain.
