I see. I guess the best thing to say is that in hypomanic episodes, one usually has
lots of energy, accomplishes many things (though not necessarily quality accomplishments), has spending sprees, uses poor judgment and can become irritable. But there are no psychotic breaks.

Unless I.Q. testing indicates genius mentality, it would be considered a form of psychotic
break if one claimed that he/she was a genius. Delusions and all the other characteristics you suggest may encompass part of a manic episode. I don't know what is considered the "cut off line" for insanity opposed to sanity, but I'm guessing that it would be strong delusional ideas that one has which are obviously contradicted by reality and which are incapacitating for one's ability to function in society. I don't think the hypomanic patient goes beyond reality in understanding.

There is, by the way, a post on the Psych Forum called something like "What is the Difference
Between Hypomania and Full-blown mania" which is a discussion between people who are talking
about their experiences related to the two subjects.
