| Explanation | [[Explanation::Borderline personality disorder is characterized by a pattern of excessive instability of interpersonal relationships and self-image. Patients are usually impulsive, have a pattern of intense unstable relationships, and recurrent suicidal behavior or threats. Patients can also exhibit mood instability, self-mutilation, and chronic feelings of emptiness. A classical defense mechanism associated with borderline personality disorder is splitting. Splitting is described as intolerance to ambiguity with a belief that people are either completely good or bad at a given time. Patients have alternating extremes of idealization and devaluation towards certain individuals.
