Borderline personality disorder refers to a longstanding pattern of unstable self-image, moods, relationships, and impulsive behaviors that usually begins in early adulthood. People with this disorder are typically unable to tolerate being alone, and their relationships tend to be unstable and intense. They also engage in risky and impulsive behaviors such as dramatic over-spending, having unsafe sex, or having sex with people they hardly know, abusing drugs or alcohol, driving recklessly, or binge-eating. It is not uncommon for people with this problem to physically hurt themselves (by cutting themselves, for example) or to try repeatedly to kill themselves. Individuals with borderline personality disorder also often experience severe mood swings, feelings of emptiness, and intense anger.
Some evidence suggests that dialectical behavioral therapy is beneficial for treatment of Borderline Personality Disorder. While other psychotherapies may be helpful for treatment of borderline personality disorder, they have not been evaluated scientifically in the same way as the treatment listed here.
