The symptoms of mania include elevated mood (either euphoric or irritable), flight of ideas, pressure of speech, increased energy, decreased "need" and desire for sleep, and hyperactivity. They are most plainly evident in fully developed hypomanic states, however, in full-blown mania, these symptoms become progressively exacerbated. In severe manic episodes, these symptoms may even be obscured by other signs and symptoms characteristic of psychosis, such as delusions, hallucinations, fragmentation of behavior, and catatonia.[5]
