People with hypomania are generally perceived as being energetic, euphoric, visionary, overflowing with new ideas, and sometimes over-confident and very charismatic.
Symptoms of hypomania include "increased motor activity, feeling agitated instead of happy, thoughts going too fast, they're distractible, and they can't concentrate."
The investigators defined subthreshold bipolar disorder as recurrent hypomania (mild hypomania) without a major depressive episode or with fewer symptoms than required for threshold hypomania.
Dysthymic disorder, or dysthymia, is characterized by long-term (2 years or longer) symptoms that may not be severe enough to disable a person but can prevent normal functioning or feeling well.
