What are the causes of borderline personality disorder and what is it?

A Lengthy subject: Briefly describing a disorder like bpd can be misleading so one has to be careful not to make conclusions. In general it is characterized by a long history of instability of mood, major difficulties in maintaining healthy relationships. Poor sense of direction & difficulties developing goals and working towards them.Substance abuse and self harm are common associations. Treatment is available.

Very lengthy topic.: Causes: partially genetic, abuse, neglect, family hx of severe psych disorders or parents with severe personality disorders. It is a personality disorder in which the person feels stably unstable, is predictably unpredictable, where people around the person feel like they are walking on eggshells and their significant others feel like they can never get too close or be too far away. See wikipedia.

Borderline: There is no easy answer to this. Borderline personality disorder, as well as the human condition in general are shaped by genetic factors in combination with environmental factors. It is characterized by fear of abandonment, impulsivity, self mutilation, extremes of emotion, volatile interpersonal relationships, thinking in all-good or all-bad terms,manipulativeness, &drug/alcohol abuse/dependence

Lengthy: This is a lengthy subjecct to discuss in a setting like this one. In general, severe traumas during childhood while the personality is being shaped are associated with development of bpd.

Complex: Neglectful or abusive parenting in the early years, early trauma (especially recurring trauma), and some genetic vulnerability is likely in the mix too. As another doctor noted, it is a a complex question. The important issue is that it is treatable, and several forms of psychotherapy have been proven effective for treatment of borderline personality disorder.
