Borderline Personality Disorder (BPD) vs Bipolar Disorder

Borderline personality disorder and bipolar disorder are two mental health conditions that are often misdiagnosed. And the reason why they’re often misdiagnosed is that both involve symptoms of sudden and intense emotional responses, depression and impulsive behavior.

However, there lies a significant difference between them in terms of the type of mental disorder, symptoms, and treatment options.

Borderline personality disorder (BPD)

Borderline personality disorder (BPD) is a personality disorder marked by a sense of alienation from people; not being able to relate to them or perceive social situations appropriately. People suffering from BPD are unable to meet behavioral social expectations, resulting in severe personal and interpersonal conflicts.

Bipolar Disorder

Bipolar disorder is a mood disorder. As the name suggests, it is about functioning across two opposite poles. Sometimes you’re high on energy, and everything appears rosy, even when things are bad. Other times, you get stuck with depression even when everything appears to be fine. People with bipolar disorder have serious changes in mood (mood swings).

Prevalence in the United States

Borderline personality disorder grips around 1.4 percent of adults in the United States, as reported by the National Institute of Mental Health. While bipolar disorder is relatively common and affects about 2.6 percent of the U.S population.

Diagnosing Borderline Personality Disorder (BPD) and Bipolar Disorder

Both mental health conditions are challenging to diagnose. Multiple medical and psychological questionnaires related to the severity and duration of symptoms are required to rule out other closely related mental disorders. 

For diagnosing BPD, a mental health professional conducts a comprehensive clinical interview with the patient, consults with previous healthcare professionals, and interviews the patient’s family, friends, and relatives too.

To diagnose bipolar disorder, you are asked to keep a track of your daily mood swings, differing energy levels, and changing sleep patterns. Its diagnosis is further categorized as bipolar I and bipolar II disorder.

Bipolar I disorder is when you have one classic episode of mania, lasting for about 7 days. Bipolar II disorder is characterized by one major depressive episode, in addition to an episode of hypomania.
