Borderline Personality Disorder As Incapacitating As Bipolar Disorder

The degeneration of psychiatric and physical health caused by borderline personality disorder equals that of bipolar disorder, according to new research.

1.6 percent of the U.S. population is diagnosed with borderline personality disorder (BPD), compared with 2.6 percent of those with bipolar disorder, estimates the National Institute of Mental Health.

Said Mark Zimmerman, M.D., researcher and director of outpatient psychiatry at Rhode Island Hospital:

“The level of psychosocial morbidity and suicidality associated with BPD is as great, or greater, than that experienced by patients with bipolar disorder. From a public health perspective, improving the detection and treatment of BPD is as imperative as diagnosing and treating bipolar disorders.”

This is the largest comparison of patients who have been diagnosed with BPD or bipolar disorder.

Persons with BPD have difficulty regulating emotions and thoughts, often teetering at extremes. They engage in impulsive and reckless behavior, and their relationships with other people are rocky.

While persons with bipolar disorder experience the same mood for weeks, those with BPD cope with intense bouts of anger, depression and anxiety that are short in duration.

According to Zimmerman’s study, clinical experience suggests that BPD is as disabling as bipolar disorders. In psychiatric patient samples, BPD is as frequent as bipolar disorder.

As in bipolar patients, persons with BPD are likely to also suffer from depression, anxiety disorders, substance abuse, eating disorders and suicidal behaviors. These co-occurring mental illnesses may have symptoms that overlap with BPD, making it difficult to recognize BPD in patients with these other mental illnesses.

“Despite the clinical and public health significance of both of these disorders, it sometimes seems as if BPD lives in the shadow of bipolar disorder,” said Zimmerman. “Bipolar disorder is a widely researched, well-publicized, well-funded topic. By contrast, BPD is seldom discussed and it is not included in the Global Burden of Disease study, a comprehensive registry that quantifies diseases by cost, mortality, geography, risk and other factors.”
