hypomania hypomania hypomania (literally "under mania" or "less than mania") is a mental and behavioral disorder, characterised essentially by an apparently non-contextual elevation of mood (euphoria) that contributes to persistently disinhibited behaviour. the individual with the condition may experience irritability, not necessarily less severe than full mania; in fact, the presence of marked irritability is a documented feature of hypomanic and mixed episodes in bipolar type ii. according to dsm-5 criteria, hypomania is distinct from mania in that there is no significant functional impairment; mania, by dsm-5 definition, does include significant functional impairment and may have psychotic features. characteristic behaviors of people experiencing hypomania are a notable decrease in the need for sleep, an overall increase in energy, unusual behaviors and actions, and a markedly distinctive increase in talkativeness and confidence, commonly exhibited with a flight of creative ideas. other symptoms related to this may include feelings of grandiosity, distractibility, and hypersexuality. while hypomanic behavior often generates productivity and excitement, it can become troublesome if the subject engages in risky or otherwise inadvisable behaviors, and/or the symptoms manifest themselves in trouble with everyday life events. when manic episodes are separated into stages of a progression according to symptomatic severity and associated features, hypomania constitutes the first stage of the syndrome, wherein the cardinal features (euphoria or heightened irritability, pressure of speech and activity, increased energy, decreased need for sleep, and flight of ideas) are most plainly evident. signs and symptoms individuals in a hypomanic state have a decreased need for sleep, are extremely gregarious and competitive, and have a great deal of energy. they are, otherwise, often fully functioning (unlike individuals experiencing a manic episode). distinctive markers specifically, hypomania is distinguished from mania by the absence of psychotic symptoms, and by its lesser degree of impact on functioning. hypomania is a feature of bipolar ii disorder and cyclothymia, but can also occur in schizoaffective disorder. hypomania is also a feature of bipolar i disorder; it arises in sequential procession as the mood disorder fluctuates between normal mood (euthymia) and mania. some individuals with bipolar i disorder have hypomanic as well as manic episodes. hypomania can also occur when moods progress downwards from a manic mood state to a normal mood. hypomania is sometimes credited with increasing creativity and productive energy. numerous people with bipolar disorder have credited hypomania with giving them an edge in their theater of work. people who experience hyperthymia, or "chronic hypomania", encounter the same symptoms as hypomania but on a longer-term basis. associated disorders
