How to Test for Borderline Personality Disorder

Borderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD), is a long-term pattern of abnormal behavior characterized by unstable relationships with other people, unstable sense of self, and unstable emotions. There is often dangerous behavior and self-harm. People may also struggle with a feeling of emptiness and a fear of abandonment. Symptoms may be brought on by seemingly normal events. The behavior typically begins by early adulthood, and occurs across a variety of situations. Substance abuse, depression, and eating disorders are commonly associated with BPD. Approximately 10% of people affected die by suicide.
