Borderline personality disorder (BPD) has been a controversial diagnosis since it was first recognized in the Diagnostic and Statistical Manual of Mental Disorders in 1980. One controversy that still has not been resolved is whether or not BPD is related to bipolar disorder since they have many similar symptoms. Show
How Bipolar and Borderline Personality Disorder Are SimilarThe primary reason that some experts have proposed that BPD and bipolar disorder may be related is that they share the common feature of mood instability. Bipolar disorder is associated with mood shifts from depression to mania, a mood characterized by elation, a decreased need for sleep and an increase in activity, or hypomania, which is similar to mania but less severe. BPD is also associated with mood changes, sometimes called emotional dysregulation or affective instability. People with BPD can frequently change from feeling fine to feeling extremely distressed in a matter of minutes. Impulsive behavior is also frequently experienced both by people with bipolar disorder and by people with BPD. How Bipolar and Borderline Personality Disorder Are DifferentWhat is the difference between BPD and bipolar disorder, then? Some major components separate the two.
Are Bipolar and Borderline Personality Disorder Related?Although it is not yet clear-cut, research has not found a strong relationship between BPD and bipolar disorder. There is some evidence that people with BPD are diagnosed with bipolar disorder at higher rates than individuals with other personality disorders. One study found that about 20% of people with BPD are also diagnosed with bipolar disorder. Only about 10% of people with other personality disorders also have a bipolar disorder diagnosis. Another study looked at people diagnosed with both BPD and bipolar disorder within a 10-year timeframe. The results showed that the disorders appear to be completely independent. The study's authors stressed that it's extremely important to treat each disorder individually for the best chance of symptom relief. The Bottom LineSo far, there is not enough research to suggest that BPD and bipolar disorder are related. Although there are definitely some shared features, there are also some marked differences between BPD and bipolar disorder. Also, the co-occurrence of BPD and bipolar disorder is not large enough to suggest that the two disorders are related. However, more research is needed on this topic. It may be that future research, for example, on the genetic and biological causes of BPD and bipolar disorder, may reveal some undiscovered relationships between the two conditions.
