Borderline Personality Disorder (BPD) is a pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:
- Frantic efforts to avoid real or imagined abandonment. Note: Do not include suicidal or self-mutilating behavior.
- A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation.
- Identity disturbance: markedly and persistently unstable self-image or sense of self.
- Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating). Note: Do not include suicidal or self-mutilating behavior.
- Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days)
- Chronic feelings of emptiness.
- Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights).
- Transient, stress-related paranoid ideation or severe dissociative symptoms
The
DSM IV goes on to say:
The essential feature of Borderline Personality Disorder is a pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity that begins by early adulthood and is present in a variety of contexts.
Associated Features and DisordersIndividuals with Borderline Personality Disorder may have a pattern of undermining themselves at the moment a goal is about to be realized (e.g., dropping out of school just before graduation; regressing severely after a discussion of how well therapy is going; destroying a good relationship just when it is clear that the relationship could last). Some individuals develop psychotic-like symptoms (e.g., hallucinations, body-image distortions, ideas of reference, and hypnotic phenomena) during times of stress. Individuals with this disorder may feel more secure with transitional objects (i.e., a pet or inanimate possession) than in interpersonal relationships. Premature death from suicide may occur in individuals with this disorder, especially in those with co-occurring Mood Disorders or Substance-Related Disorders. Physical handicaps may result from self-inflicted abuse behaviors or failed suicide attempts. Recurrent job losses, interrupted education, and broken marriages are common. Physical and sexual abuse, neglect, hostile conflict, and early parental loss or separation are more common in the childhood histories of those with Borderline Personality Disorder. Common co-occurring Axis I disorders include Mood Disorders, Substance-Related Disorders, Eating Disorders (notably Bulimia), Posttraumatic Stress Disorder, and Attention-Deficit/Hyperactivity Disorder. Borderline Personality Disorder also frequently co-occurs with the other Personality Disorders.
Specific Culture, Age, and Gender FeaturesThe pattern of behavior seen in Borderline Personality Disorder has been identified in many settings around the world. Adolescents and young adults with identity problems (especially when accompanied by substance abuse) may transiently display behaviors that misleadingly give the impression of Borderline Personality Disorder. Such situations are characterized by emotional instability, "existential" dilemmas, uncertainty, anxiety-provoking choices, conflicts about sexual orientation, and competing social pressures to decide on careers. Borderline Personality Disorder is diagnosed predominantly (about 75%) in females.
PrevalenceThe prevalence of Borderline Personality Disorder is estimated to be about 2% of the general population, about 10% among individuals seen in outpatient mental health clinics, and about 20% among psychiatric inpatients. In ranges from 30% to 60% among clinical populations with Personality Disorders.
CourseThere is considerable variability in the course of Borderline Personality Disorder. The most common pattern is one of chronic instability in early adulthood, with episodes of serious affective and impulsive dyscontrol and high levels of use of health and mental health resources. The impairment from the disorder and the risk of suicide are greatest in the young-adult years and gradually wane with advancing age. During their 30s and 40s, the majority of individuals with this disorder attain greater stability in their relationships and vocational functioning.
Familial PatternBorderline Personality Disorder is about five times more common among first-degree biological relatives of those with the disorder than in the general population. There is also an increased familial risk for Substance-Related Disorders, Antisocial Personality Disorder, and Mood Disorders.
Differential DiagnosisBorderline Personality Disorder often co-occurs with Mood Disorders, and when criteria for both are met, both may be diagnosed. Because the cross-sectional presentation of Borderline Personality Disorder can be mimicked by an episode of Mood Disorder, the clinician should avoid giving an additional diagnosis of Borderline Personality Disorder based only on cross-sectional presentation without having documented that the pattern of behavior has an early onset and a long-standing course.
