Post by Former NIMH Director Thomas Insel: What’s in a Name? — The Outlook for Borderline Personality Disorder
By Thomas Insel on
- 61 percent also have at least one anxiety disorder, most commonly a specific phobia, or social phobia
- 49 percent have an impulse-control disorder, most commonly intermittent explosive disorder
- 38 percent have a substance abuse or dependence disorder, most commonly alcohol abuse or dependence
- 34 percent have a mood disorder, most commonly dysthymia (mild, chronic depression), or major depression.
One of the most tragic outcomes for any mental disorder, suicide, presents an especially high risk in this population. As many as 80 percent of people with borderline personality disorder have suicidal behaviors,2 and about 4-9 percent complete suicide.2,3
Despite these overwhelming statistics, proper treatment can help reduce or lessen the severity of symptoms. Treatment may mean short-term hospitalization, especially when there is an immediate threat to a person’s life, such as from suicidal behaviors and alcohol or drug dependence. But in most cases, psychotherapy, or “talk therapy,” is effective in helping people to manage even the most destructive symptoms of the illness. For example, an NIMH-funded study of 101 women with borderline personality disorder showed that dialectical behavior therapy (DBT) reduced suicide attempts by half compared with other types of psychotherapy. DBT also excelled at reducing use of emergency room and inpatient services and retained more participants in therapy, compared to other mostly traditional approaches to treatment.2
Aiming to improve the way we think about and study borderline personality disorder and other mental illnesses, efforts to reclassify these disorders are underway, including NIMH’s own RDoC project. In particular, the goal of RDoC is to examine basic categories of mental function, such as fear or working memory, which cut across traditional disorder definitions. This approach will allow researchers to link the genetic and social underpinnings of a particular mental function with their associated biochemical and neural processes and resultant behaviors or other symptoms. Whatever the outcome of reclassification efforts, however, we must keep in mind the essence of the question — that “borderline personality disorder” by any other name would still be as real, as disabling, and as necessary to treat, as other serious mental illnesses.
