The symptoms of mania include elevated mood (either euphoric or irritable), flight of ideas, pressure of speech, increased energy, decreased "need" and desire for sleep, and hyperactivity. They are most plainly evident in fully developed hypomanic states, however, in full-blown mania, these symptoms become progressively exacerbated. In severe manic episodes, these symptoms may even be obscured by other signs and symptoms characteristic of psychosis, such as delusions (it may include delusions of grandeur and paranoid delusions{{cite journal | last=Picardi | first=Angelo | last2=Fonzi | first2=Laura | last3=Pallagrosi | first3=Mauro | last4=Gigantesco | first4=Antonella | last5=Biondi | first5=Massimo | title=Delusional Themes Across Affective and Non-Affective Psychoses | journal=Frontiers in Psychiatry | volume=9 | date=2018-04-05 | issn=1664-0640 | pmid=29674982 | pmc=5895977 | doi=10.3389/fpsyt.2018.00132 | doi-access=free | page=}}), hallucinations, fragmentation of behavior, and catatonia.

Mania is a syndrome with multiple causes.{{Cite journal |last=Krauthammer |first=Charles |date=1978-11-01 |title=Secondary Mania: Manic Syndromes Associated With Antecedent Physical Illness or Drugs |url=http://archpsyc.jamanetwork.com/article.aspx?doi=10.1001/archpsyc.1978.01770350059005 |journal=Archives of General Psychiatry |language=en |volume=35 |issue=11 |pages=1333–1339 |doi=10.1001/archpsyc.1978.01770350059005 |pmid=757997 |issn=0003-990X|url-access=subscription }} Although the vast majority of cases occur in the context of bipolar disorder, it is a key component of other psychiatric disorders (such as schizoaffective disorder, bipolar type I) and may also occur secondary to various general medical conditions, such as multiple sclerosis; due to certain medications that may perpetuate a manic state (for example prednisone); or substances prone to abuse, especially stimulants, such as amphetamine and cocaine. In the current DSM-5, hypomanic episodes are separated from the more severe full manic episodes, which, in turn, are characterized as either mild, moderate, or severe, with certain diagnostic criteria (e.g., catatonia, psychosis). There is though a "staging" of manic episodes that can be useful from a descriptive and differential diagnostic point of view.{{cite journal|last1=Coon|first1=Hilary|last2=Hoff|first2=Mark|last3=Holik|first3=John|last4=Byerley|first4=William|date=1995|title=Search for a gene predisposing to manic-depression on chromosome 21|journal=American Journal of Medical Genetics|volume=60|issue=3|pages=231–233|doi=10.1002/ajmg.1320600312|pmid=7573177|ref=130}}{{Cite journal |last1=Adamec |first1=Ivan |last2=Ozretić |first2=David |last3=Habek |first3=Mario |date=2012-11-16 |title=Autonomic dysfunction in multiple sclerosis presenting with postural orthostatic tachycardia |url=http://dx.doi.org/10.1007/s13760-012-0158-2 |journal=Acta Neurologica Belgica |volume=113 |issue=3 |pages=337–339 |doi=10.1007/s13760-012-0158-2 |pmid=23160808 |issn=0300-9009}}

Classification
= Mixed states =
{{Main|Mixed affective state}}
In a mixed affective state, the individual, though meeting the general criteria for a hypomanic (discussed below) or manic episode, experiences three or more concurrent depressive symptoms. This has caused some speculation, among clinicians{{Who|date=February 2024}}, that mania and depression, rather than constituting "true" polar opposites, are, rather, two independent axes in a unipolar—bipolar spectrum.
A mixed affective state, especially with prominent manic symptoms, places the patient at a greater risk for suicide. Depression on its own is a risk factor but, when coupled with an increase in energy and goal-directed activity, the patient is far more likely to act on suicidal impulses.

Some studies exploring brain metabolism in subjects with hypomania, however, did not find any conclusive link; while there are studies that reported abnormalities, others failed to detect differences.{{Cite book|title=Bipolar Disorder Vulnerability: Perspectives from Pediatric and High-Risk Populations|last1=Soares|first1=Jair|last2=Walss-Bass|first2=Consuelo|last3=Brambilla|first3=Paolo|publisher=Academic Press|year=2018|isbn=9780128123478|location=London|pages=218}} Though the elevated mood and energy level typical of hypomania could be seen positively, mania itself generally has many undesirable consequences, including suicidal tendencies. Hypomania can also have these effects, if the prominent mood is irritable as opposed to euphoric. In addition, the intense cases of hypomania can lead to problems. Where trait-based positivity for a person could make them more engaging, outgoing, and cause them to have a positive outlook in life,{{Cite book|title=The Hypomania Handbook: The Challenge of Elevated Mood|last=Doran|first=Christopher M.|publisher=Lippincott Williams & Wilkins|year=2007|isbn=9780781775205|location=Philadelphia.

= Associated disorders =
A single manic episode, in the absence of secondary causes, (i.e., substance use disorders, certain medications, 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.
Evidence indicates a vitamin B12 deficiency can also cause symptoms characteristic of mania and psychosis.{{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 B12 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 }} 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.{{MedlinePlusEncyclopedia|000356|Hyperthyroidism}}{{EMedicine|article|121865|Hyperthyroidism}}
Postpartum psychosis can also cause manic episodes (unipolar mania).
Signs and symptoms
A manic episode is defined in the American Psychiatric Association's diagnostic manual (DSM) as a "distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently increased activity or energy, lasting at least 1 week and present most of the day, nearly every day (or any duration, if hospitalization is necessary),"{{cite web |date=September 2016 |website=PsychiatryOnline |publisher=American Psychiatric Association Publishing |url=http://psychiatryonline.org/pb-assets/dsm/update/DSM5Update2016.pdf |title=DSM-5 Update: Supplement to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition |access-date=2017-04-19 |archive-date=2020-08-03 |archive-url=https://web.archive.org/web/20200803065243/https://psychiatryonline.org/pb-assets/dsm/update/DSM5Update2016.pdf |url-status=live }} where the mood is not caused by drugs/medication or a non-mental medical illness (e.g., hyperthyroidism), and: (a) is causing obvious difficulties at work or in social relationships and activities, or (b) requires admission to hospital to protect the person or others, or (c) the person has psychosis.{{cite web |title=Manic Episode |url=https://www.behavenet.com/manic-episode |access-date=4 July 2024 |website=behavenet.com}}{{cbignore|bot=medic}}
To be classified as a manic episode, while the disturbed mood and an increase in goal-directed activity or energy is present, at least three (or four, if only irritability is present) of the following must have been consistently present:
- Inflated self-esteem or grandiosity.
- Decreased need for sleep (e.g., feels rested after 3 hours of sleep).
- More talkative than usual, or acts pressured to keep talking.
- Flights of ideas or subjective experience that thoughts are racing.
- Increase in goal-directed activity, or psychomotor acceleration.
- Distractibility (too easily drawn to unimportant or irrelevant external stimuli).
- Excessive involvement in activities with a high likelihood of painful consequences. (e.g., extravagant shopping, improbable commercial schemes, hypersexuality).
Though the activities one participates in while in a manic state are not always negative, those with the potential to have negative outcomes are more common.
If the person is concurrently depressed, they are said to be having a mixed episode.
The World Health Organization's International Classification of Diseases (ICD) defines a manic episode as one where mood is higher than the person's situation warrants and may vary from relaxed high spirits to barely controllable exuberance, is accompanied by hyperactivity, a compulsion to speak, a reduced sleep requirement, difficulty sustaining attention, and/or often increased distractibility. Frequently, confidence and self-esteem are excessively enlarged, and grand, extravagant ideas are expressed. Behavior that is out-of-character and risky, foolish or inappropriate may result from a loss of normal social restraint.{{cite web|url=http://apps.who.int/classifications/icd10/browse/2010/en#/F30|title=Manic episode|access-date=18 November 2016|archive-date=2 November 2014|archive-url=https://web.archive.org/web/20141102133725/http://apps.who.int/classifications/icd10/browse/2010/en#/F30|url-status=live}}
Some people also have physical symptoms, such as sweating, pacing, and weight loss. In full-blown mania, often the manic person will feel as though their goal(s) are of paramount importance, that there are no consequences, or that negative consequences would be minimal, and that they need not exercise restraint in the pursuit of what they are after.DSM-IV Hypomania is different, as it may cause little or no impairment in function. The hypomanic person's connection with the external world, and its standards of interaction, remain intact, although intensity of moods is heightened. But those with prolonged unresolved hypomania do run the risk of developing full mania, and may do so without even realizing they have.AJ Giannini. Biological Foundations of Clinical Psychiatry, NY Medical Examination Publishing Company, 1986.
One of the signature symptoms of mania (and to a lesser extent, hypomania) is what many have described as racing thoughts. These are usually instances in which the manic person is excessively distracted by objectively unimportant stimuli.Lakshmi N. Ytham, Vivek Kusumakar, Stanley P. Kutchar. (2002). Bipolar Disorder: A Clinician's Guide to Biological Treatments, page 3. This experience creates an absent-mindedness where the manic individual's thoughts totally preoccupy them, making them unable to keep track of time, or be aware of anything besides the flow of thoughts. Racing thoughts also interfere with the ability to fall asleep.
Manic states are always relative to the normal state of intensity of the affected individual; thus, already irritable patients may find themselves losing their tempers even more quickly, and an academically gifted person may, during the hypomanic stage, adopt seemingly "genius" characteristics and an ability to perform and articulate at a level far beyond that which they would be capable of during euthymia. A very simple indicator of a manic state would be if a thus far clinically depressed patient suddenly becomes inordinately energetic, enthusiastic, cheerful, aggressive, or "over-happy". Other, often less obvious, elements of mania include delusions (generally of either grandeur or persecution, according to whether the predominant mood is euphoric or irritable), hypersensitivity, hypervigilance, hypersexuality, hyper-religiosity, hyperactivity and impulsivity, a compulsion to over explain (typically accompanied by pressure of speech), grandiose schemes and ideas, and a decreased need for sleep (for example, feeling rested after only 3 or 4 hours of sleep). In the case of the latter, the eyes of such patients may both look and seem abnormally "wide open", rarely blinking, and may contribute to some clinicians' erroneous belief that these patients are under the influence of a stimulant drug, when the patient, in fact, is either not on any mind-altering substances or is actually on a depressant drug. Individuals may also engage in out-of-character behavior during the episode, such as questionable business transactions, wasteful expenditures of money (e.g., spending sprees), risky sexual activity, abuse of recreational substances, excessive gambling, reckless behavior (such as extreme speeding or other daredevil activity), abnormal social interaction (e.g., over-familiarity and conversing with strangers), or highly vocal arguments. These behaviours may increase stress in personal relationships, lead to problems at work, and increase the risk of altercations with law enforcement. There is a high risk of impulsively taking part in activities potentially harmful to the self and others.{{cite journal |vauthors=Fletcher K, Parker G, Paterson A, Synnott H | title = High-risk behaviour in hypomanic states | journal = J Affect Disord | volume = 150 | issue = 1 | pages = 50–6 | year = 2013 | pmid = 23489397 | doi = 10.1016/j.jad.2013.02.018 }}{{cite journal |vauthors=Pawlak J, Dmitrzak-Węglarz M, Skibińska M, Szczepankiewicz A, Leszczyńska-Rodziewicz A, Rajewska-Rager A, Maciukiewicz M, Czerski P, Hauser J | title = Suicide attempts and psychological risk factors in patients with bipolar and unipolar affective disorder | journal = Gen Hosp Psychiatry | volume = 35 | issue = 3 | pages = 309–13 | year = 2013 | pmid = 23352318 | doi = 10.1016/j.genhosppsych.2012.11.010 }}
The experience of mania is often quite unpleasant and sometimes frightening, for the person involved and for those close to them, and it may lead to impulsive behaviour that may later be regretted. It can also often be complicated by the individual's lack of judgment and insight regarding periods of exacerbation of characteristic states. Manic patients may frequently deny anything is wrong with them.{{Citation |last1=Dailey |first1=Mark W. |title=Mania |date=2023 |url=http://www.ncbi.nlm.nih.gov/books/NBK493168/ |work=StatPearls |access-date=2023-12-29 |place=Treasure Island (FL) |publisher=StatPearls Publishing |pmid=29630220 |last2=Saadabadi |first2=Abdolreza |archive-date=2024-01-11 |archive-url=https://web.archive.org/web/20240111090418/https://ncbi.nlm.nih.gov/books/NBK493168/ |url-status=live }} Because mania frequently encourages high energy and decreased perception of need or ability to sleep, within a few days of a manic cycle, sleep-deprived psychosis may appear, further complicating the ability to think clearly.
Mania may also, as earlier mentioned, be divided into three "stages". Stage I corresponds with hypomania and may feature typical hypomanic characteristics, such as gregariousness and euphoria. In stages II and III mania, however, the patient may be extraordinarily irritable, psychotic or even delirious. These latter two stages are referred to as acute and delirious (or Bell's), respectively.
Causes
Various triggers have been associated with switching from euthymic or depressed states into mania. One common trigger of mania is antidepressant therapy. Studies show that the risk of switching while on an antidepressant is between 6-69 percent. Dopaminergic drugs such as reuptake inhibitors and dopamine agonists may also increase risk of switch. Other medications possibly include glutaminergic agents and drugs that alter the HPA axis. Lifestyle triggers include irregular sleep-wake schedules and sleep deprivation, as well as extremely emotional or stressful stimuli.{{cite journal|last1=Salvadore|first1=Giacomo|last2=Quiroz|first2=Jorge A.|last3=Machado-Vieira|first3=Rodrigo|last4=Henter|first4=Ioline D.|last5=Manji|first5=Husseini K.|last6=Zarate|first6=Carlos A.|title=The Neurobiology of the Switch Process in Bipolar Disorder: a Review|journal=The Journal of Clinical Psychiatry|date=Nov 2010|volume=71|issue=11|pages=1488–1501|doi=10.4088/JCP.09r05259gre|issn=0160-6689|pmc=3000635|pmid=20492846}}
Various genes that have been implicated in genetic studies of bipolar have been manipulated in preclinical animal models to produce syndromes reflecting different aspects of mania. CLOCK and DBP polymorphisms have been linked to bipolar in population studies, and behavioral changes induced by knockout are reversed by lithium treatment. Metabotropic glutamate receptor 6 has been genetically linked to bipolar, and found to be under-expressed in the cortex. Pituitary adenylate cyclase-activating peptide has been associated with bipolar in gene linkage studies, and knockout in mice produces mania like-behavior. Targets of various treatments such as GSK-3, and ERK1 have also demonstrated mania like behavior in preclinical models.{{cite journal|last1=Sharma|first1=AN|last2=Fries|first2=GR|last3=Galvez|first3=JF|last4=Valvassori|first4=SS|last5=Soares|first5=JC|last6=Carvalho|first6=AF|last7=Quevedo|first7=J|title=Modeling mania in preclinical settings: A comprehensive review.|journal=Progress in Neuro-Psychopharmacology & Biological Psychiatry|date=3 April 2016|volume=66|pages=22–34|doi=10.1016/j.pnpbp.2015.11.001|pmid=26545487|pmc=4728043}}

Mechanism
{{Further|Biology of bipolar disorder}}
The mechanism underlying mania is unknown, but the neurocognitive profile of mania is highly consistent with dysfunction in the right prefrontal cortex, a common finding in neuroimaging studies.{{cite journal|last1=Clark|first1=L|last2=Sahakian|first2=BJ|title=Cognitive neuroscience and brain imaging in bipolar disorder.|journal=Dialogues in Clinical Neuroscience|date=2008|volume=10|issue=2|pages=153–63|doi=10.31887/DCNS.2008.10.2/lclark|pmid=18689286|pmc=3181872}}{{cite journal|last1=Arnsten|first1=AFT|last2=Manji|first2=HK|last3=Haberland|first3=G|title=Mania: a rational neurobiology|journal=Future Neurology|date=March 2008|volume=3|issue=2|pages=125–131|doi=10.2217/14796708.3.2.125}} Various lines of evidence from post-mortem studies and the putative mechanisms of anti-manic agents point to abnormalities in GSK-3,{{cite journal |vauthors=Li X, Liu M, Cai Z, Wang G, Li X | title = Regulation of glycogen synthase kinase-3 during bipolar mania treatment | journal = Bipolar Disord | volume = 12 | issue = 7 | pages = 741–52 | year = 2010 | pmid = 21040291 | pmc = 3059222 | doi = 10.1111/j.1399-5618.2010.00866.x }} dopamine, Protein kinase C, and Inositol monophosphatase.{{cite book | last1 = Goodman | first1 = Brunton L, Chabner B, Knollman B | title = Goodman Gilman's pharmacological basis of therapeutics | date = 2011 | publisher = McGraw-Hill Professional | location = New York | isbn = 978-0-07-162442-8 | edition = Twelfth }}
Meta analysis of neuroimaging studies demonstrate increased thalamic activity, and bilaterally reduced inferior frontal gyrus activation.{{cite journal|last1=Chen|first1=CH|last2=Suckling|first2=J|last3=Lennox|first3=BR|last4=Ooi|first4=C|last5=Bullmore|first5=ET|title=A quantitative meta-analysis of fMRI studies in bipolar disorder.|journal=Bipolar Disorders|date=February 2011|volume=13|issue=1|pages=1–15|doi=10.1111/j.1399-5618.2011.00893.x|pmid=21320248}} Activity in the amygdala and other subcortical structures such as the ventral striatum tend to be increased, although results are inconsistent and likely dependent upon task characteristics such as valence.

Post-mortem examinations of bipolar disorder demonstrate increased expression of Protein Kinase C (PKC).{{cite book|last1=Gawryluk|first1=J|last2=Young|first2=T|editor1-last=Manji|editor1-first=H|editor2-last=Zarate|editor2-first=C|title=Behavioral Neurobiology of Bipolar Disorder And its Treatment|publisher=Springer|pages=151–152|chapter=Signal Transduction Pathways in the Pathophysiology of Bipolar Disorder}} While limited, some studies demonstrate manipulation of PKC in animals produces behavioral changes mirroring mania, and treatment with PKC inhibitor tamoxifen (also an anti-estrogen drug) demonstrates antimanic effects. Traditional antimanic drugs also demonstrate PKC inhibiting properties, among other effects such as GSK3 inhibition.
Manic episodes may be triggered by dopamine receptor agonists, and this combined with tentative reports of increased VMAT2 activity, measured via PET scans of radioligand binding, suggests
a role of dopamine in mania. Decreased cerebrospinal fluid levels of the serotonin metabolite 5-HIAA have been found in manic patients too, which may be explained by a failure of serotonergic regulation and dopaminergic hyperactivity.{{cite journal|last1=MANJI|first1=HUSSEINI K|last2=QUIROZ|first2=JORGE A|last3=PAYNE|first3=JENNIFER L|last4=SINGH|first4=JASKARAN|last5=LOPES|first5=BARBARA P|last6=VIEGAS|first6=JENILEE S|last7=ZARATE|first7=CARLOS A|title=The underlying neurobiology of bipolar disorder|journal=World Psychiatry|date=Oct 2003|volume=2|issue=3|pages=136–146|issn=1723-8617|pmc=1525098|pmid=16946919}}
Limited evidence suggests that mania is associated with behavioral reward hypersensitivity, as well as with neural reward hypersensitivity. Electrophysiological evidence supporting this comes from studies associating left frontal EEG activity with mania. As left frontal EEG activity is generally thought to be a reflection of behavioral activation system activity, this is thought to support a role for reward hypersensitivity in mania. Tentative evidence also comes from one study that reported an association between manic traits and feedback negativity during receipt of monetary reward or loss. Neuroimaging evidence during acute mania is sparse, but one study reported elevated orbitofrontal cortex activity to monetary reward, and another study reported elevated striatal activity to reward omission. The latter finding was interpreted in the context of either elevated baseline activity (resulting in a null finding of reward hypersensitivity), or reduced ability to discriminate between reward and punishment, still supporting reward hyperactivity in mania.{{cite journal|last1=Nusslock|first1=Robin|last2=Young|first2=Christina B.|last3=Damme|first3=Katherine S.

Diagnosis
In the ICD-10, there are several disorders with the manic syndrome: organic manic disorder ({{ICD10|F|06|30}}), mania without psychotic symptoms ({{ICD10|F|30|1}}), mania with psychotic symptoms ({{ICD10|F|30|2}}), other manic episodes ({{ICD10|F|30|8}}), unspecified manic episode ({{ICD10|F|30|9}}), manic type of schizoaffective disorder ({{ICD10|F|25|0}}), bipolar disorder, current episode manic without psychotic symptoms ({{ICD10|F|31|1}}), bipolar affective disorder, current episode manic with psychotic symptoms ({{ICD10|F|31|2}}).{{Cite web |date=September 1988 |title=Organic Causes of Mania |url=https://www.mayoclinicproceedings.org/article/S0025-6196%2812%2962694-9/pdf |access-date=April 27, 2024 |website=mayoclinicproceedings.org |archive-date=November 27, 2022 |archive-url=https://web.archive.org/web/20221127183605/https://www.mayoclinicproceedings.org/article/S0025-6196(12)62694-9/pdf |url-status=live }}
Treatment
Before beginning treatment for mania, careful differential diagnosis must be performed to rule out secondary causes.
The acute treatment of a manic episode of bipolar disorder involves the utilization of either a mood stabilizer (e.g.,carbamazepine, valproate, lithium, or lamotrigine) or an atypical antipsychotic (e.g., olanzapine, quetiapine, risperidone, aripiprazole, or cariprazine).{{Cite journal |last1=Pacchiarotti |first1=I. |last2=Anmella |first2=G. |last3=Colomer |first3=L. |last4=Vieta |first4=E. |date=September 2020 |title=How to treat mania |url=https://onlinelibrary.wiley.com/doi/10.1111/acps.13209 |journal=Acta Psychiatrica Scandinavica |language=en |volume=142 |issue=3 |pages=173–192 |doi=10.1111/acps.13209 |pmid=33460070 |s2cid=221616169 |issn=0001-690X |access-date=2022-04-20 |archive-date=2022-08-09 |archive-url=https://web.archive.org/web/20220809161811/https://onlinelibrary.wiley.com/doi/10.1111/acps.13209 |url-status=live |url-access=subscription }} More recently, substances such as iloperidone have been approved for the acute treatment of manic episodes related to bipolar I disorder.{{Cite web |date=2024-04-02 |title=FDA Approves Fanapt for Mixed, Manic Episodes Associated With Bipolar I Disorder |url=https://www.psychiatrictimes.com/view/fda-approves-fanapt-for-mixed-manic-episodes-associated-with-bipolar-i-disorder |access-date=2024-04-27 |website=Psychiatric Times |language=en |archive-date=2024-04-27 |archive-url=https://web.archive.org/web/20240427051528/https://www.psychiatrictimes.com/view/fda-approves-fanapt-for-mixed-manic-episodes-associated-with-bipolar-i-disorder |url-status=live }} The use of antipsychotic agents in the treatment of acute mania was reviewed by Tohen and Vieta in 2009.{{Cite journal|last1=Tohen|first1=Mauricio|last2=Vieta|first2=Eduard|date=2009|title=Antipsychotic agents in the treatment of bipolar mania |journal=Bipolar Disorders|volume=11|issue=s2|pages=45–54|doi=10.1111/j.1399-5618.2009.00710.x|doi-access=free |issn=1399-5618|pmid=19538685}}
When the manic behaviours have gone, long-term treatment then focuses on prophylactic treatment to try to stabilize the patient's mood, typically through a combination of pharmacotherapy and psychotherapy. The likelihood of having a relapse is very high for those who have experienced two or more episodes of mania or depression. While medication for bipolar disorder is important to manage symptoms of mania and depression, studies show relying on medications alone is not the most effective method of treatment. Medication is most effective when used in combination with other bipolar disorder treatments, including psychotherapy, self-help coping strategies, and healthy lifestyle choices.{{cite web |url=http://www.helpguide.org/mental/bipolar_disorder_medications.htm/ |title=The Bipolar Medication Guide |author1=Melinda Smith |author2=Lawrence Robinson |author3=Jeanne Segal |author4=Damon Ramsey |publisher=HelpGuide.org |date=1 March 2012 |access-date=23 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120310190007/http://helpguide.org/mental/bipolar_disorder_medications.htm |archive-date=10 March 2012 }}{{Cite journal |last1=Novick |first1=Danielle M. |last2=Swartz |first2=Holly A. |date=2019 |title=Evidence-Based Psychotherapies for Bipolar Disorder |journal=Focus: Journal of Life Long Learning in Psychiatry |volume=17 |issue=3 |pages=238–248 |doi=10.1176/appi.focus.20190004 |issn=1541-4094 |pmc=6999214 |pmid=32047369}}
Lithium is the classic mood stabilizer to prevent further manic and depressive episodes. A systematic review found that long term lithium treatment substantially reduces the risk of bipolar manic relapse, by 42%.{{cite journal |vauthors=Geddes JR, Burgess S, Hawton K, Jamison K, Goodwin GM | title = Long-term lithium therapy for bipolar disorder: systematic review and meta-analysis of randomized controlled trials. | journal = The American Journal of Psychiatry | volume = 161 | issue = 2 | pages = 217–22 | date = February 2004 | pmid = 14754766 | doi = 10.1176/appi.ajp.161.2.217 }} Anticonvulsants such as valproate, oxcarbazepine, and carbamazepine are also used for prophylaxis. More recent drug solutions include lamotrigine and topiramate, both anticonvulsants as well.
In some cases, long-acting benzodiazepines, particularly clonazepam, are used after other options are exhausted. In more urgent circumstances, such as in emergency rooms, lorazepam, combined with haloperidol, is used to promptly alleviate symptoms of agitation, aggression, and psychosis.
Antidepressant monotherapy is not recommended for the treatment of depression in patients with bipolar disorders I or II, and no benefit has been demonstrated by combining antidepressants with mood stabilizers in these patients. Some atypical antidepressants, however, such as mirtazapine and trazodone, have been occasionally used after other options have failed.{{cite journal | author = Nierenberg AA | title = A critical appraisal of treatments for bipolar disorder | journal = Primary Care Companion to the Journal of Clinical Psychiatry | volume = 12 | issue = Suppl 1 | pages = 23–29 | year = 2010 | pmid = 20628503 | pmc = 2902191 | doi = 10.4088/PCC.9064su1c.04 }}
Society and culture
In Electroboy: A Memoir of Mania by Andy Behrman, he describes his experience of mania as "the most perfect prescription glasses with which to see the world... life appears in front of you like an oversized movie screen."{{cite book|last=Behrman, Andy|title=Electroboy: A Memoir of Mania|year=2002|pages=Preface: Flying High|publisher=Random House Trade Paperbacks|isbn=978-0-8129-6708-1}} Behrman indicates early in his memoir that he sees himself not as a person with an uncontrollable disabling illness, but as a director of the movie that is his vivid and emotionally alive life.

Etymology
The nosology of the various stages of a manic episode has changed over the decades. The word derives from the Ancient Greek μανία (manía), "madness, frenzy"[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dmani%2Fa1 μανία] {{Webarchive|url=https://web.archive.org/web/20210226163442/http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3Dmani%2Fa1 |date=2021-02-26 }}, Henry George Liddell, Robert Scott, A Greek-English Lexicon, on Perseus Digital Library and the verb μαίνομαι (maínomai), "to be mad, to rage, to be furious."[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0057%3Aentry%3D μαίνομαι], Henry George Liddell, Robert Scott, A Greek-English Lexicon, on Perseus Digital Library
