'''Borderline personality disorder''' ('''BPD''') is a [[mental illness]] marked by black-and-white thinking and an instability in [[mood]], [[self-image]], behavior, and [[interpersonal relationship]]s. BPD is often comorbid with anxiety and mood disorders (including [[bipolar disorder]]). The disorder occurs in approximately 1% to 2% of the general population, and is more common in women than men, with a 3:1 ratio. BPD also includes difficulty in controlling anger, or anger over small things, chronic [[emptiness]], fear of abandonment, self-harm, or suicidal behavior. The term "borderline" arises from the idea that one could be borderline between [[psychosis]] and [[neurosis]], athough this idea has fallen out of favor. Numerous studies have shown there is a relation between BPD and childhood abuse. Many with BPD report having been abused or neglected as a child. There may also be a genetic factor. One study of identical twins found that when one twin had BPD there would be a 35% chance that the other would have BPD.<ref>Torgersen S, Lygren S, Oien PA, Skre I, Onstad S, Edvardsen J, Tambs K, Kringlen E.
