Here is an excellent and informative video featuring three people who suffered and were successfully treated for their BPD. Marsha Linehan, a psychologist who also had BPD and developed DBT therapy for borderline patients, is also featured, as well as Otto Kernberg, an psychologist who specializes in NPD and BPD.
BPD is best defined as a severe lack of a sense of self which has its roots in abuse and often sexual abuse during childhood and adolescence but it also has a genetic component. Brain scans of people with BPD show their brains are actually wired differently. Self destructive behaviors such as cutting serve to help the sufferer regulate their emotions for the short term. Borderlines find their inability to regulate their emotions so painful and debilitating that many resort to suicide. One shocking statistic is that 8 – 10% of borderlines will ultimately either kill themselves or die of their self destructive behaviors.
Unlike people with NPD, medications that “turn off” the parts of the brain that overreact to emotional stimuli have been successful for treating and controlling BPD symptoms. Also, while people with BPD are more impaired in being able to function than people with NPD, therapy is much more likely to be successful.
