Hypomania is a less severe form of mania, without progression to psychosis. Many of the symptoms of mania are present, but to a lesser degree than in overt mania.
People with hypomania are generally perceived as being energetic, euphoric, overflowing with new ideas, and sometimes highly confident and charismatic, and unlike full-blown mania, they are sufficiently capable of coherent thought and action to participate in everyday life.
