Bipolar disorder covers a spectrum of mood disorders characterized by major mood swings. The mood swings can range from manic or hypomanic high moods to depressed low moods. Borderline personality disorder (BPD), on the other hand, is a personality disorder marked by instability in behaviors, functioning, mood, and self-image.
Many of the symptoms of bipolar disorder and borderline personality disorder overlap. This is particularly the case with type 1 bipolar disorder, which involves intense manic episodes. Some symptoms shared between bipolar disorder and BPD include:
- extreme emotional reactions
- impulsive actions
- suicidal behaviors
