There are two basic types of mania (or hypomania): euphoric and dysphoric.
A person can experience both types when they have bipolar disorder.
In euphoria, a person is high, in love with the world, one with the world,
feeling boundless energy, talking a mile a minute, mind is racing, deluded
with grandiose thoughts, etc. This kind of mania is generally the kind
described in the popular literature.
Dysphoria is another type of mania. In dysphoria one is "high" but in a
different sense: agitated, destructive, full of rage, talking a mile a minute,
mind racing, deluded with grandiose thoughts, paranoid, full of anxiety,
In addition, dysphoria can also come into the depressive side. These are often
referred to as "mixed episodes." Mixed episodes are quite dangerous; suicidal
ideation often accompanies this state.
What's the difference between agitated depression and dysphoric (hypo)mania?
Dr. Ivan Goldberg (firstname.lastname@example.org) explains: "While folks in an agitated
depression show increased motor activity, they never show increased
sociability, increased creative thinking, joking and punning that may be seen
in someone experiencing a dysphoric (hypo)manic state."
