What is Personality Disorder NOS?

Personality disorder NOS (Not Otherwise Specified) is referred to by the DSM-IV-TR as disorders that do not fit into any personality disorder categories. These include: passive-aggressive personality disorder and depressive personality disorder; some behavior or particular trait such as oppositionalism, sadism, and masochism can also be classified in this category. 1

On the other hand, a closely related category known as the borderline personality disorder (BPD) is defined by the Diagnostic and Statistical Manual of Mental Disorders DSM-IV as a prolonged disturbance of personality function which is characterized by depth and variability of moods. The disorder typically involves unusual levels of mood instability or mood swings, black and white thinking, or splitting; chaotic and unstable interpersonal relationships, self-image, identity, and behavior; as well as a disturbance in the individual's sense of self. In severe cases, manifestations of these disturbances in the sense of self may lead to periods of dissociation. It can have an insidious negative impact on many or all of the psychosocial aspects of life, which includes difficulties keeping relationships in work, home, and social settings. As a result, both attempted and completed suicides are possible to happen to these people, especially without proper care and effective therapy. 2

This disorder has also been referred to as ambulatory schizophrenia, as-if personality which is a term given by Helene Deutsch, pseudoneurotic schizophrenia as described by Paul Hoch and Philip Politan, psychotic character disorder as described by John Frosch. ICD-10 makes use of the name emotionally unstable personality disorder. 3
