Question

Quizplus · Accepted Answer

Mood disorders are all characterized by emotional extremes, whether it be depression, mania, or a combination of both. While negative mood states are certainly a common feature, not all mood disorders are solely defined by negativity (i.e. bipolar disorder can involve both depression and manic episodes). The duration and presence of irrational thoughts are not universal features of all mood disorders.
