by excessive swings in a person’s mood and energy affecting their
ability to function.  BPD is a lifetime recurrent disorder with cycles
of dramatic mood swings of highs and lows, often with periods of normal
moods in between.  The periods of highs and lows are called episodes of
mania and depression.  BPD is also associated with increased
cardiovascular morbidity and suicide risk. The US and EU population of
