Borderline personality disorder (BPD) (called emotionally unstable personality disorder, borderline type in the ICD-10) is a cluster-B personality disorder whose essential features are a pattern of marked impulsivity and instability of affects, interpersonal relationships, and self image.
The pattern is present by early adulthood and occurs across a variety of situations and contexts. Other symptoms may include intense fears of abandonment and intense anger and irritability that others have difficulty understanding the reason for.People with BPD often engage in idealization and devaluation of others, alternating between high positive regard and great disappointment. Self-mutilation and suicidal behavior are common.
This disorder is recognized by the Diagnostic and Statistical Manual of Mental Disorders, which specifies that it "begins by early adulthood". Because a personality disorder is a pervasive, enduring and inflexible pattern of maladaptive inner experience and pathological behavior, there is a general reluctance to diagnose personality disorders before adolescence or early adulthood. Some emphasize, however, that without early treatment, symptoms may worsen.
There is an ongoing debate about the terminology of this disorder, especially the word "borderline". The ICD-10 manual refers to this disorder as Emotionally unstable personality disorder and has similar diagnostic criteria. There is related concern that the diagnosis of BPD stigmatizes people with BPD and supports discriminatory practices because it suggests that the personality of the individual is flawed. In the DSM-5, the name of the disorder remains the same.
