2. What is Bipolar Disorder?
The same source points out there are many similarities to BPD, but 1-of the main characteristics that separate the 2-conditions is that bipolar patients tend to have a “break” in their symptoms that lands them in a “mid-range” mood that doesn’t include extreme anger or impulsiveness.
Examining interpersonal relationships can also be another clue to which condition is present. The source says that personality disorders are likely triggered by “conflict within relationships,” while bipolar symptoms “usually appear out of nowhere.”
