In brief: Hypo mania vs mania

Both usually have depression.
Bipolar1 includes mania. Bipolar 2 includes hypo mania. Hypo mania is less severe, but still can have consequences due to impulsivity. Consequences are much more severe with mania. See my other answers for additional details.

The hallmarks of a bipolar II mania are irritability "hiding" a core of grandiose self-regard. Impulse behavior can be a big part of II as we

In brief: Difference

Bipolar I and bipolar II, In the first, manic phases are more severe, and in the second, depressive phases are more severe.
There is also cyclothymia which is a low grade version of bipolar disorder in general, where mood swings are not as severe in either direction, manic or depressive.
