Signs and symptoms
Hypomania may feel good to the person who experiences it. Thus, even when family and friends learn to recognize the mood swings, the individual often will deny that anything is wrong. What might be called a “hypomanic event”, if it not accompanied by complementary depressive episodes (“downs”, etcetera), is not typically deemed as problematic whatsoever: the “problem” arises when mood changes are uncontrollable and, more importantly, volatile or “mercurial”. If unaccompanied by depressive counterpart episodes or otherwise general irritability, this behavior is typically called hyperthymia, or happiness, which is of course perfectly normal. Indeed, the most elementary definition of bipolar disorder is an often “violent” or “jarring” state of essentially uncontrollable oscillation between hyperthymia and dysthymia.
Mixed affective episode
In the context of bipolar disorder, a mixed state is a condition during which symptoms of mania and clinical depression occur simultaneously (for example, agitation, anxiety, aggressiveness or belligerence, confusion, fatigue, impulsiveness, insomnia, irritability, morbid and/or suicidal ideation, panic, paranoia, persecutory delusions, pressured speech, racing thoughts, restlessness, and rage).
