Borderline Personality Disorder (BPD) is a condition characterized by difficulties regulating emotion. This means that people who experience BPD feel emotions intensely and for extended periods of time, and it is harder for them to return to a stable baseline after an emotionally triggering event.
This difficulty can lead to impulsivity, poor self-image, stormy relationships and intense emotional responses to stressors. Struggling with self-regulation can also result in dangerous behaviors such as self-harm (e.g. cutting).
It’s estimated that 1.6% of the adult U.S. population has BPD, but that number may be as high as 5.9%. Nearly 75% of people diagnosed with BPD are women. Recent research suggests that men may be equally affected by BPD but are commonly misdiagnosed with PTSD or depression.
