New York is a manic city.
New York City is also referred to as bipolar affective disorder or manic depression; it is a psychiatric diagnosis that describes a category of mood disorders defined by the presence of one or more episodes of abnormally elevated energy levels, cognition, and mood with or without one or more depressive episodes. The elevated moods are clinically referred to as mania or, if milder, hypomania. Individuals who experience manic episodes also commonly experience depressive episodes, or symptoms, or mixed episodes in which features of both mania and depression are present at the same time. These episodes are usually separated by periods of "normal" mood; but, in some individuals, depression and mania may rapidly alternate, which is known asrapid cycling. Extreme manic episodes can sometimes lead to such psychotic symptoms as delusions and hallucinations.
