A single manic episode, in the absence of secondary causes, (i.e., substance use disorders, pharmacologics, or general medical conditions) is often sufficient to diagnose bipolar I disorder. Hypomania may be indicative of bipolar II disorder. Manic episodes are often complicated by delusions and/or hallucinations; and if the psychotic features persist for a duration significantly longer than the episode of typical mania (two weeks or more), a diagnosis of schizoaffective disorder is more appropriate. Certain obsessive-compulsive spectrum disorders as well as impulse control disorders share the suffix "-mania," namely, kleptomania, pyromania, and trichotillomania. Despite the unfortunate association implied by the name, however, no connection exists between mania or bipolar disorder and these disorders.
