Hypomania (literally, "below mania") is a mood state characterized by persistent and pervasive elevated (euphoric) or irritable mood, as well as thoughts and behaviors that are consistent with such a mood state. It is most often associated with the bipolar spectrum. Many who are in a hypomanic state are extremely energetic, talkative, confident, and assertive.
