Bipolar 2 is 1+ HYPOMANIC episodes (NO MANIC EPISODES)
What is cyclothymia?
Periods of HYPOmanic symptoms (that do NOT meet hypomanic criteria)
Periods of depressive symptoms (that do NOT meet MDD criteria)
How prevalent is Bipolar disorder?
1% for both BP1 and BP2.
83% of cases are severe.
Most likely due to underreporting since there is no push for a BP pt to seek treatment.
What is the MC demographic for BP disorder?
Equal race and gender.
Higher incidence in higher socioeconomic status.
18-20 is most common.
Younger pts are at higher risk for getting their 1st episode.

This will require additional medications like mood stabilizers.

Anxiety
Catatonic
Mixed
Psychotic
Atypical
Melancholic
