Editing Mania (section)

=== Associated disorders ===
A single manic episode, in the absence of secondary causes, (i.e., [[substance use disorder]]s, certain [[medication]]s, 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 [[delusion]]s and/or [[hallucination]]s; and if the [[Psychosis|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 disorder]]s 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. 

Evidence indicates a [[Vitamin B12 deficiency|vitamin B<sub>12</sub> deficiency]] can also cause symptoms characteristic of mania and psychosis.<ref name="imajvitaminb12">{{cite journal |vauthors=Masalha R, Chudakov B, Muhamad M, Rudoy I, Volkov I, Wirguin I |title=Cobalamin-responsive psychosis as the sole manifestation of vitamin B<sub>12</sub> deficiency |journal=Israeli Medical Association Journal |volume=3 |year=2001 |pages=701–703 |url=http://www.ima.org.il/imaj/dynamic/web/ArtFromPubmed.asp?year=2001&month=09&page=701 |access-date=2009-09-12 |archive-date=2012-03-07 |archive-url=https://web.archive.org/web/20120307014434/http://www.ima.org.il/imaj/dynamic/web/ArtFromPubmed.asp?year=2001&month=09&page=701 |url-status=dead }}</ref> [[Hyperthyroidism]] can produce similar symptoms to those of mania, such as agitation, elevated mood, increased energy, hyperactivity, sleep disturbances and sometimes, especially in severe cases, psychosis.<ref>{{MedlinePlusEncyclopedia|000356|Hyperthyroidism}}</ref><ref>{{EMedicine|article|121865|Hyperthyroidism}}</ref>
