Mania
Hypomania

Hypomania, which means "less than mania", is a lowered state of mania that does not always impair function or decrease quality of life. Although creativity and hypomania have been historically linked, a review and meta-analysis exploring this relationship found that this assumption may be too general and empirical research evidence is lacking. In hypomania, there is less need for sleep and both goal-motivated behaviour and metabolism increase. Some studies exploring brain metabolism in subjects with hypomania, however, did not find any conclusive link; while there are studies that reported abnormalities, others failed to detect differences. Though the elevated mood and energy level typical of hypomania could be seen positively, mania itself generally has many undesirable consequences, including suicidal tendencies. Hypomania can also have these effects, if the prominent mood is irritable as opposed to euphoric. In addition, the intense cases of hypomania can lead to problems. Where trait-based positivity for a person could make them more engaging, outgoing, and cause them to have a positive outlook in life, exaggerated in hypomania, such a person can display excessive optimism, grandiosity, and poor decision-making, often with little regard to the consequences.
