And there you see the heart of this debate what is Borderline? A mood disorder or personality disorder? Well for now the majority of the mental health field professionals consider it a personality disorder, but NOT without resistance or constant debate. Many feel it should be in the mood disorder category because those new criteria used for making it a personality thing are and have been present with bipolars. So what exactly made it a personality disorder then?

You will hear a couple of things.

1. Well a Bipolar mood swings for longer duration.
2. A BPD mood swings are shorter duration.

Well they seem to agree it's a mood disorder there lol. The durations can easily be explained as simply a milder version of bipolar.

3. Yes but bipolar is triggered by chemical imbalanced and BPD is triggered by events.

Says who? There is even disagreement here! Recently doctors noticed thyroid changes in BPD people when their mood changes just like in bipolar people! Also, the idea of what causes the trigger is not enough even forsake of argument assuming is true not enough to warrant a massive change to a personality disorder.
