text_A: Hypomania is the milder form of mania, defined as at least four days of the same criteria as mania, but which does not cause a significant decrease in the individual's ability to socialize or work, lacks psychotic features such as delusions or hallucinations, and does not require psychiatric hospitalization. Overall functioning may actually increase during episodes of hypomania and is thought to serve as a defense mechanism against depression by some. It is rare for a full-on manic episode to result from a hypomanic episode. Some people who experience hypomania show increased creativity while others are irritable or demonstrate poor judgment.
text_B: From the way hypomania is described here, could a layperson reasonably conclude that it's possible that many people may actually have hypomanic episodes from time to time, yet never get a diagnosis, or indeed, even think that there ever was a problem?
YES.
