Borderline personality disorder (BPD) is a mental health disorder. People with BPD may often have dramatic, emotional, erratic, and attention-seeking moods. This behavior disrupts family and work life, long-term planning, and the individual’s sense of self.

The causes of BPD are not fully understood. It is thought to be a combination of brain chemistry, genetics, and environmental factors. People who develop BPD are probably born vulnerable to the illness. Certain experiences and types of stress may then further increase their chance of developing BPD. Many BPD sufferers are often found to have experienced childhood abuse, neglect, separation, sexual abuse, violence, or brain injury.
