A recent study showed that Bipolar Type II, often thought of as the less severe form of Bipolar Disorder, is actually worse than Bipolar Type I is some ways.
Some of the ways Bipolar II is more severe than Bipolar I:
- increased comorbid anxiety
- increased first-degree relative with mood disorder
- more prior mood episodes
- current depression
- current antidepressant use
- rapid cycling in the prior year
- childhood onset
On the other hand, Bipolar II patients had significantly less hospitalizations and current prescription psychotropic use compared to Bipolar I patients.
Both groups had a statistically similar rate of prior suicide attempts.
