During mania, an individual behaves or feels abnormally energetic, happy, or irritable. Individuals often make poorly thought out decisions with little regard to the consequences. The need for sleep is usually reduced during manic phases. During periods of depression, there may be crying, a negative outlook on life, and poor eye contact with others. The risk of suicide among those with the illness is high at greater than 6 percent over 20 years, while self-harm occurs in 30–40 percent.JOURNAL, Anderson IM, Haddad PM, Scott J, Bipolar disorder, BMJ (Clinical Research Ed.), December 27, 2012, 345, e8508, 23271744, 10.1136/bmj.e8508, Other mental health issues such as anxiety disorders and substance use disorder are commonly associated with bipolar disorder.The causes are not clearly understood, but both environmental and genetic factors play a role. Many genes, each with small effects, contribute to the disorder.JOURNAL, Goodwin, Guy M., Bipolar disorder, Medicine, 40, 11, 596–598, 10.1016/j.mpmed.2012.08.011, 2012, Environmental risk factors include a history of childhood abuse and long-term stress. About 85% of the risk is attributed to genetics.BOOK, Charney, Alexander, Sklar, Pamela, Charney, Dennis, Nestler, Eric, Sklar, Pamela, Buxbaum, Joseph, vanc, Charney & Nestler's Neurobiology of Mental Illness, 2018, Oxford University Press, New York, 162, 5th, Genetics of Schizophrenia and Bipolar Disorder,weblink's%20Neurobiology%20of%20Mental%20Illness&pg=PA162, The condition is classified as bipolar I disorder if there has been at least one manic episode, with or without depressive episodes, and as bipolar II disorder if there has been at least one hypomanic episode (but no full manic episodes) and one major depressive episode. In those with less severe symptoms of a prolonged duration, the condition cyclothymic disorder may be diagnosed. If the symptoms are due to drugs or medical problems, it is classified separately.BOOK, American Psychiatry Association, Diagnostic and Statistical Manual of Mental Disorders, 2013, American Psychiatric Publishing, Arlington, 978-0-89042-555-8, 123–154, 5th, Other conditions that may present similarly include attention deficit hyperactivity disorder, personality disorders, schizophrenia and substance use disorder as well as a number of medical conditions. Medical testing is not required for a diagnosis, though blood tests or medical imaging can be done to rule out other problems.WEB, Bipolar Disorder,weblink NIMH, National Institutes of Health, April 2016, August 13, 2016, live,weblink" title="">weblink July 27, 2016, Bipolar disorder is treated with medications, such as mood stabilizers and antipsychotics, as well as with psychotherapy.JOURNAL, Goodwin GM, Haddad PM, Ferrier IN, Aronson JK, Barnes T, Cipriani A, Coghill DR, Fazel S, Geddes JR, Grunze H, Holmes EA, Howes O, Hudson S, Hunt N, Jones I, Macmillan IC, McAllister-Williams H, Miklowitz DR, Morriss R, Munafò M, Paton C, Saharkian BJ, Saunders K, Sinclair J, Taylor D, Vieta E, Young AH, Evidence-based guidelines for treating bipolar disorder: Revised third edition recommendations from the British Association for Psychopharmacology, Journal of Psychopharmacology, 30, 6, 495–553, June 2016, 26979387, 4922419, 10.1177/0269881116636545, Currently, medication remains the key to successful practice for most patients in the long term. ... At present the preferred strategy is for continuous rather than intermittent treatment with oral medicines to prevent new mood episodes., Mood stabilizers may improve mood disturbances, and include lithium and certain anticonvulsants such as valproate and carbamazepine. Involuntary treatment in a psychiatric hospital may be needed if a person is a risk to themselves or others but refuses treatment. Severe behavioral problems, such as agitation or combativeness, may be managed with short-term antipsychotics or benzodiazepines. In periods of mania, it is recommended that antidepressants be stopped. If antidepressants are used for periods of depression, they should be used with a mood stabilizer. Electroconvulsive therapy (ECT), while not very well studied, may be tried for those who do not respond to other treatments.JOURNAL, Versiani M, Cheniaux E, Landeira-Fernandez J, Efficacy and safety of electroconvulsive therapy in the treatment of bipolar disorder: a systematic review, The Journal of ECT, 27, 2, 153–64, June 2011, 20562714, 10.1097/yct.0b013e3181e6332e, If any treatment is stopped, it is recommended that this be done slowly. Many individuals have financial, social or work-related problems due to the illness. These difficulties occur a quarter to a third of the time, on average. Due to lifestyle choices and the side effects of medications, the risk of death from natural causes such as coronary heart disease in people with bipolar is twice that of the general population.Bipolar disorder affects approximately 1% of the global population.JOURNAL, Grande I, Berk M, Birmaher B, Vieta E, Bipolar disorder, Lancet, 387, 10027, 1561–72, April 2016, 26388529, 10.1016/S0140-6736(15)00241-X, Review, In the United States, about 3% are estimated to be affected at some point in their life; rates appear to be similar in females and males.JOURNAL, Schmitt A, Malchow B, Hasan A, Falkai P, The impact of environmental factors in severe psychiatric disorders, Front Neurosci, 8, 19, 19, February 2014, 10.3389/fnins.2014.00019, 3920481, 24574956, JOURNAL, Diflorio A, Jones I, Is sex important?

Signs and symptoms

(File:Bipolar mood shifts.png|thumb|Bipolar mood shifts)Both mania and depression are characterized by disruptions in normal mood, psychomotor activity, circadian rhythm, and cognition. Mania can present with varying levels of mood disturbance, ranging from euphoria that is associated with "classic mania" to dysphoria and irritability. The core symptom of mania involves an increase in energy of psychomotor activity. Mania can also present with increased self-esteem or grandiosity, rapid speech, the subjective feeling of rapid thoughts, disinhibited social behavior, or impulsivity.BOOK, Akiskal, Hagop, Sadock, Benjamin, Sadock, Virginia, Ruiz, Pedro, vanc, Kaplan and Sadock's Comprehensive Textbook of Psychiatry, 2017, Wolters Kluwer, New York, 10th, 13.4 Mood Disorders: Clinical Features, Mania is distinguished from hypomania by length, as hypomania requires four consecutive days, and mania requires more than a week. Unlike mania, hypomania is not always associated with impaired functioning. The biological mechanisms responsible for switching from a manic or hypomanic episode to a depressive episode, or vice versa, remain poorly understood.JOURNAL, Salvadore G, Quiroz JA, Machado-Vieira R, Henter ID, Manji HK, Zarate CA, The neurobiology of the switch process in bipolar disorder: a review, The Journal of Clinical Psychiatry, 71, 11, 1488–501, November 2010, 20492846, 3000635, 10.4088/JCP.09r05259gre,

Manic episodes

(File:A woman diagnosed as suffering from hilarious mania. Colour Wellcome L0026687.jpg|thumb|left|An 1892 color lithograph depicting a woman diagnosed with "Hilarious Mania")Mania is a distinct period of at least one week of elevated or irritable mood, which can range from euphoria to delirium, and those experiencing hypomania or mania generally exhibit several of the following behaviors: speaking in a rapid, uninterruptible manner, decreased need for sleep, short attention span, racing thoughts, increased goal-oriented activities, agitation, or exhibition of behaviors characterized as impulsive or high-risk, such as hypersexuality or excessive spending.JOURNAL, Tarr GP, Glue P, Herbison P, November 2011, Comparative efficacy and acceptability of mood stabilizer and second generation antipsychotic monotherapy for acute mania—a systematic review and meta-analysis, J Affect Disord, 134, 1–3, 14–9, 10.1016/j.jad.2010.11.009, 21145595, JOURNAL, Beentjes TA, Goossens PJ, Poslawsky IE, October 2012, Caregiver burden in bipolar hypomania and mania: a systematic review, Perspect Psychiatr Care, 48, 4, 187–97, 10.1111/j.1744-6163.2012.00328.x, 23005586, To meet the definition for a manic episode, these behaviors must impair the individual's ability to socialize or work. If untreated, a manic episode usually lasts three to six months.JOURNAL, Titmarsh S, Characteristics and duration of mania: implications for continuation treatment, Progress in Neurology and Psychiatry, May–June 2013, 17, 3, 26–7, 10.1002/pnp.283, Manic individuals often have a history of substance abuse developed over years as a form of "self-medication". At the most extreme, a person in a full-blown manic state can experience psychosis: a break with reality, a state in which thinking is affected along with mood. They may feel unstoppable, or as if they have been "chosen" and are on a "special mission", or have other grandiose or delusional ideas.JOURNAL, Knowles R, McCarthy-Jones S, Rowse G, Grandiose delusions: a review and theoretical integration of cognitive and affective perspectives, Clin Psychol Rev, 31, 4, 684–96, June 2011, 21482326, 10.1016/j.cpr.2011.02.009, This may lead to violent behavior and, sometimes, hospitalization in an inpatient psychiatric hospital. The severity of manic symptoms can be measured by rating scales such as the Young Mania Rating Scale, though questions remain about the reliability of these scales.JOURNAL, Furukawa TA, Assessment of mood: Guides for clinicians, Journal of Psychosomatic Research, 68, 6, 581–589, 2010, 20488276, 10.1016/j.jpsychores.2009.05.003, The onset of a manic or depressive episode is often foreshadowed by sleep disturbances.JOURNAL, McKenna BS, Eyler LT, Overlapping prefrontal systems involved in cognitive and emotional processing in euthymic bipolar disorder and following sleep deprivation: a review of functional neuroimaging studies, Clin Psychol Rev, 32, 7, 650–63, November 2012, 22926687, 3922056, 10.1016/j.cpr.2012.07.003, Mood changes, psychomotor and appetite changes, and an increase in anxiety can also occur up to three weeks before a manic episode develops.

Hypomanic episodes

(File:'Melancholy passing into mania' Wellcome L0022595 (cropped).jpg|thumb|An 1858 lithograph captioned 'Melancholy passing into mania')Hypomania is the milder form of mania, defined as at least four days of the same criteria as mania, but which does not cause a significant decrease in the individual's ability to socialize or work, lacks psychotic features such as delusions or hallucinations, and does not require psychiatric hospitalization. Overall functioning may actually increase during episodes of hypomania and is thought to serve as a defense mechanism against depression by some. Hypomanic episodes rarely progress to full-blown manic episodes. Some people who experience hypomania show increased creativityJOURNAL, Srivastava S, Ketter TA, December 2010, The link between bipolar disorders and creativity: evidence from personality and temperament studies., Current Psychiatry Reports, 12, 6, 522–30, 10.1007/s11920-010-0159-x, 20936438, while others are irritable or demonstrate poor judgment.Hypomania may feel good to some persons who experience it, though most people who experience hypomania state that the stress of the experience is very painful. Bipolar people who experience hypomania, however, tend to forget the effects of their actions on those around them. Even when family and friends recognize mood swings, the individual will often deny that anything is wrong.WEB,weblink Bipolar Disorder: NIH Publication No. 95-3679, U.S. National Institutes of Health, September 1995,weblink" title="">weblink April 29, 2008, What might be called a "hypomanic event", if not accompanied by depressive episodes, is often not deemed problematic, unless the mood changes are uncontrollable, or volatile.JOURNAL, Bowins B, Cognitive regulatory control therapies, Am J Psychother, 67, 3, 215–36, 2007, 24236353, 10.1176/appi.psychotherapy.2013.67.3.215, Most commonly, symptoms continue for a few weeks to a few months.WEB,weblink Bipolar II Disorder Symptoms and Signs, Web M.D., December 6, 2010, live,weblink" title="">weblink December 9, 2010,

Depressive episodes

File:'Melancholy' by W. Bagg Wellcome L0022594.jpg|thumb|left|'Melancholy' by W. Bagg after a photograph by Hugh Welch DiamondHugh Welch DiamondSymptoms of the depressive phase of bipolar disorder include persistent feelings of sadness, irritability or anger, loss of interest in previously enjoyed activities, excessive or inappropriate guilt, hopelessness, sleeping too much or not enough, changes in appetite and/or weight, fatigue, problems concentrating, self-loathing or feelings of worthlessness, and thoughts of death or suicide. In severe cases, the individual may develop symptoms of psychosis, a condition also known as severe bipolar disorder with psychotic features. These symptoms include delusions and hallucinations. A major depressive episode persists for at least two weeks, and may result in suicide if left untreated.BOOK, APA Practice Guidelines for the Treatment of Psychiatric Disorders: Comprehensive Guidelines and Guideline Watches, 1, 2006, 10.1176/appi.books.9780890423363.50051, Practice Guideline for the Treatment of Patients With Bipolar Disorder Second Edition, 978-0-89042-336-3, American Psychiatric Association, The earlier the age of onset, the more likely the first few episodes are to be depressive.JOURNAL, Bowden CL, Strategies to reduce misdiagnosis of bipolar depression, Psychiatr Serv, 52, 1, 51–5, January 2001, 11141528, 10.1176/, Since a diagnosis of bipolar disorder requires a manic or hypomanic episode, many affected individuals are initially misdiagnosed as having major depression and then incorrectly treated with prescribed antidepressants.JOURNAL, Muzina DJ, Kemp DE, McIntyre RS, Differentiating bipolar disorders from major depressive disorders: treatment implications, Ann Clin Psychiatry, 19, 4, 305–12, October–December 2007, 18058287, 10.1080/10401230701653591,

Mixed affective episodes

In bipolar disorder, mixed state is a condition during which symptoms of both mania and depression occur simultaneously.JOURNAL, Swann AC, Lafer B, Perugi G, Frye MA, Bauer M, Bahk WM, Scott J, Ha K, Suppes T, Bipolar mixed states: an international society for bipolar disorders task force report of symptom structure, course of illness, and diagnosis, Am J Psychiatry, 170, 1, 31–42, January 2013, 23223893, 10.1176/appi.ajp.2012.12030301, Individuals experiencing a mixed state may have manic symptoms such as grandiose thoughts while simultaneously experiencing depressive symptoms such as excessive guilt or feeling suicidal. Mixed states are considered to be high-risk for suicidal behavior since depressive emotions such as hopelessness are often paired with mood swings or difficulties with impulse control. Anxiety disorders occur more frequently as a comorbidity in mixed bipolar episodes than in non-mixed bipolar depression or mania. Substance abuse (including alcohol) also follows this trend, thereby appearing to depict bipolar symptoms as no more than a consequence of substance abuse.

Associated features

Associated features are clinical phenomena that often accompany the disorder but are not part of the diagnostic criteria. In adults with the condition, bipolar disorder is often accompanied by changes in cognitive processes and abilities.JOURNAL, MacQueen GM, Memedovich KA, Cognitive dysfunction in major depression and bipolar disorder: Assessment and treatment options, Psychiatry and Clinical Neurosciences, 71, 1, 18–27, January 2017, 27685435, 10.1111/pcn.12463, Review, These include reduced attentional and executive capabilities and impaired memory.JOURNAL, Cipriani G, Danti S, Carlesi C, Cammisuli DM, Di Fiorino M, Bipolar Disorder and Cognitive Dysfunction: A Complex Link, The Journal of Nervous and Mental Disease, 205, 10, 743–756, October 2017, 28961594, 10.1097/NMD.0000000000000720, Review, How the individual processes the universe also depends on the phase of the disorder, with differential characteristics between the manic, hypomanic and depressive states.JOURNAL, Mansell W, Pedley R, The ascent into mania: a review of psychological processes associated with the development of manic symptoms, Clinical Psychology Review, 28, 3, 494–520, March 2008, 17825463, 10.1016/j.cpr.2007.07.010, Those with bipolar disorder may have difficulty in maintaining relationships.{{sfn|Goodwin|Jamison|2007|p=338}} There are several common childhood precursors seen in children who later receive a diagnosis of bipolar disorder, such as mood abnormalities (including major depressive episodes) and attention deficit hyperactivity disorder (ADHD).JOURNAL, Reinhardt MC, Reinhardt CA, Attention deficit-hyperactivity disorder, comorbidities, and risk situations, Jornal de Pediatria, 89, 2, 124–30, March–April 2013, 23642421, 10.1016/j.jped.2013.03.015,

Comorbid conditions

The diagnosis of bipolar disorder can be complicated by coexisting (comorbid) psychiatric conditions including the following: obsessive-compulsive disorder, substance-use disorder, eating disorders, attention deficit hyperactivity disorder, social phobia, premenstrual syndrome (including premenstrual dysphoric disorder), or panic disorder.JOURNAL, Post RM, Kalivas P, Bipolar disorder and substance misuse: pathological and therapeutic implications of their comorbidity and cross-sensitisation, Br J Psychiatry, 202, 3, 172–6, March 2013, 23457180, 10.1192/bjp.bp.112.116855, mdy-all, 4340700, JOURNAL, Kerner B, Genetics of bipolar disorder, Appl Clin Genet, 7, 33–42, February 2014, 24683306, 10.2147/tacg.s39297, 3966627, JOURNAL, Cirillo PC, Passos RB, Bevilaqua MC, López JR, Nardi AE, Bipolar disorder and Premenstrual Syndrome or Premenstrual Dysphoric Disorder comorbidity: a systematic review, Rev Bras Psiquiatr, 34, 4, 467–79, December 2012, 23429819, 10.1016/j.rbp.2012.04.010, A careful longitudinal analysis of symptoms and episodes, enriched if possible by discussions with friends and family members, is crucial to establishing a treatment plan where these comorbidities exist.JOURNAL, Sagman D, Tohen M, Comorbidity in Bipolar Disorder: The Complexity of Diagnosis and Treatment, Psychiatric Times, 2009,weblink live,weblink" title="">weblink April 28, 2009,


The causes of bipolar disorder likely vary between individuals and the exact mechanism underlying the disorder remains unclear.JOURNAL, Nierenberg AA, Kansky C, Brennan BP, Shelton RC, Perlis R, Iosifescu DV, Mitochondrial modulators for bipolar disorder: a pathophysiologically informed paradigm for new drug development, Aust N Z J Psychiatry, 47, 1, 26–42, January 2013, 22711881, 10.1177/0004867412449303, Genetic influences are believed to account for 60–80 percent of the risk of developing the disorder indicating a strong hereditary component. The overall heritability of the bipolar spectrum has been estimated at 0.71.JOURNAL, Edvardsen J, Torgersen S, Røysamb E, Lygren S, Skre I, Onstad S, Oien PA, Heritability of bipolar spectrum disorders. Unity or heterogeneity?, Journal of Affective Disorders, 106, 3, 229–240, 2008, 17692389, 10.1016/j.jad.2007.07.001, Twin studies have been limited by relatively small sample sizes but have indicated a substantial genetic contribution, as well as environmental influence. For bipolar disorder type I, the rate at which identical twins (same genes) will both have bipolar disorder type I (concordance) is estimated at around 40 percent, compared to about 5 percent in fraternal twins.JOURNAL, Kieseppä T, Partonen T, Haukka J, Kaprio J, Lönnqvist J, High Concordance of Bipolar I Disorder in a Nationwide Sample of Twins, American Journal of Psychiatry, 161, 10, 1814–1821, 2004, 15465978, 10.1176/appi.ajp.161.10.1814, A combination of bipolar I, II, and cyclothymia similarly produced rates of 42 percent and 11 percent (identical and fraternal twins, respectively), with a relatively lower ratio for bipolar II that likely reflects heterogeneity. There is overlap with major (unipolar) depression and if this is also counted in the co-twin the concordance with bipolar disorder rises to 67 percent in identical twins and 19 percent in fraternal twins.JOURNAL, McGuffin P, Rijsdijk F, Andrew M, Sham P, Katz R, Cardno A, The Heritability of Bipolar Affective Disorder and the Genetic Relationship to Unipolar Depression, Archives of General Psychiatry, 60, 5, 497–502, 2003, 12742871, 10.1001/archpsyc.60.5.497, The relatively low concordance between fraternal twins brought up together suggests that shared family environmental effects are limited, although the ability to detect them has been limited by small sample sizes. Estrogen in women has been linked to bipolar disorder.JOURNAL, Rapkin AJ, Mikacich JA, Moatakef-Imani B, Rasgon N, The clinical nature and formal diagnosis of premenstrual, postpartum, and perimenopausal affective disorders, Current Psychiatry Reports, 4, 6, 419–28, December 2002, 12441021, 10.1007/s11920-002-0069-7, JOURNAL, Meinhard N, Kessing LV, Vinberg M, The role of estrogen in bipolar disorder, a review, Nordic Journal of Psychiatry, 68, 2, 81–7, February 2014, 23510130, 10.3109/08039488.2013.775341,


Behavioral genetic studies have suggested that many chromosomal regions and candidate genes are related to bipolar disorder susceptibility with each gene exerting a mild to moderate effect. The risk of bipolar disorder is nearly ten-fold higher in first degree-relatives of those affected with bipolar disorder when compared to the general population; similarly, the risk of major depressive disorder is three times higher in relatives of those with bipolar disorder when compared to the general population.Although the first genetic linkage finding for mania was in 1969,JOURNAL, Reich T, Clayton PJ, Winokur G, Family history studies: V. The genetics of mania, The American Journal of Psychiatry, 125, 10, 1358–69, April 1969, 5304735, 10.1176/ajp.125.10.1358, the linkage studies have been inconsistent.JOURNAL, Barnett JH, Smoller JW, The genetics of bipolar disorder, Neuroscience, 164, 1, 331–43, November 2009, 19358880, 3637882, 10.1016/j.neuroscience.2009.03.080, The largest and most recent genome-wide association study (GWAS) failed to find any particular locus that exerts a large effect, reinforcing the idea that no single gene is responsible for bipolar disorder in most cases. Polymorphisms in BDNF, DRD4, DAO, and TPH1 have been frequently associated with bipolar disorder and were initially successful in a meta-analysis, but failed after correction for multiple testing.JOURNAL, Seifuddin F, Mahon PB, Judy J, Pirooznia M, Jancic D, Taylor J, Goes FS, Potash JB, Zandi PP, Meta-analysis of genetic association studies on bipolar disorder, American Journal of Medical Genetics.

In diagnosis, caregiver-scored rating scales, specifically the mother, has been found to be more accurate than teacher and youth report in predicting identifying youths with bipolar disorder.JOURNAL, Youngstrom EA, Genzlinger JE, Egerton GA, Van Meter AR, Multivariate Meta-Analysis of the Discriminative Validity of Caregiver, Youth, and Teacher Rating Scales for Pediatric Bipolar Disorder: Mother Knows Best About Mania, Archives of Scientific Psychology, 3, 1, 112–137,weblink December 7, 2016, 10.1037/arc0000024, 2015, Assessment is usually done on an outpatient basis; admission to an inpatient facility is considered if there is a risk to oneself or others.

The ICD-10 criteria are used more often in clinical settings outside of the U.S. while the DSM criteria are used clinically within the U.S. and are the prevailing criteria used internationally in research studies. The DSM-5, published in 2013, included further and more accurate specifiers compared to its predecessor, the DSM-IV-TR.BOOK, Perugi G, Ghaemi SN, Akiskal H, Bipolar Psychopharmacotherapy, 193–234, 2006, 10.1002/0470017953.ch11, Diagnostic and Clinical Management Approaches to Bipolar Depression, Bipolar II and Their Comorbidities, 978-0-470-01795-1, Caring for the Patient, Semi structured interviews such as the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS) and the Structured Clinical Interview for DSM-IV (SCID) are used for diagnostic confirmation of bipolar disorder.Several rating scales for the screening and evaluation of bipolar disorder exist, including the Bipolar spectrum diagnostic scale, Mood Disorder Questionnaire, the General Behavior Inventory and the Hypomania Checklist.JOURNAL, Picardi A, Rating scales in bipolar disorder, Current Opinion in Psychiatry, 22, 1, 42–9, January 2009, 19122534, 10.1097/YCO.0b013e328315a4d2, The use of evaluation scales cannot substitute a full clinical interview but they serve to systematize the recollection of symptoms.

Differential diagnosis

There are several other mental disorders with symptoms similar to those seen in bipolar disorder. These disorders include schizophrenia, major depressive disorder, attention deficit hyperactivity disorder (ADHD), and certain personality disorders, such as borderline personality disorder.JOURNAL, Sood AB, Razdan A, Weller EB, Weller RA, How to differentiate bipolar disorder from attention deficit hyperactivity disorder and other common psychiatric disorders: A guide for clinicians, Current Psychiatry Reports, 7, 2, 98–103, 2005, 15802085, 10.1007/s11920-005-0005-8, JOURNAL, Magill CA, The boundary between borderline personality disorder and bipolar disorder: Current concepts and challenges, Canadian Journal of Psychiatry, 49, 8, 551–556, 2004, 15453104, 10.1177/070674370404900806, JOURNAL, Bassett D, Borderline personality disorder and bipolar affective disorder.

Neurologic diseases such as multiple sclerosis, complex partial seizures, strokes, brain tumors, Wilson's disease, traumatic brain injury, Huntington's disease, and complex migraines can mimic features of bipolar disorder. An EEG may be used to exclude neurological disorders such as epilepsy, and a CT scan or MRI of the head may be used to exclude brain lesions. Additionally, disorders of the endocrine system such as hypothyroidism, hyperthyroidism, and Cushing's disease are in the differential as is the connective tissue disease systemic lupus erythematosus. Infectious causes of mania that may appear similar to bipolar mania include herpes encephalitis, HIV, influenza, or neurosyphilis. Certain vitamin deficiencies such as pellagra (niacin deficiency), Vitamin B12 deficiency, folate deficiency, and Wernicke Korsakoff syndrome (thiamine deficiency) can also lead to mania.A review of current and recent medications and drug use is considered to rule out these causes; common medications that can cause manic symptoms include antidepressants, prednisone, Parkinson's disease medications, thyroid hormone, stimulants (including cocaine and methamphetamine), and certain antibiotics.JOURNAL, Peet M, Peters S, Drug-induced mania, Drug Safety, 12, 2, 146–53, February 1995, 7766338, 10.2165/00002018-199512020-00007,

Bipolar spectrum

(File:E. Kraepelin.jpg|alt=Kraepelin looking to the side|thumb|right|Since Emil Kraepelin's distinction between bipolar disorder and schizophrenia in the 19th century, researchers have defined a spectrum of different types of bipolar disorder)Bipolar spectrum disorders includes: bipolar I disorder, bipolar II disorder, cyclothymic disorder and cases where subthreshold symptoms are found to cause clinically significant impairment or distress. These disorders involve major depressive episodes that alternate with manic or hypomanic episodes, or with mixed episodes that feature symptoms of both mood states. The concept of the bipolar spectrum is similar to that of Emil Kraepelin's original concept of manic depressive illness.WEB, Korn ML, Across the Bipolar Spectrum: From Practice to Research,weblink Medscape, live,weblink" title="">weblink December 14, 2003, mdy-all, Unipolar hypomania without accompanying depression has been noted in the medical literature.JOURNAL, Beesdo K, Höfler M, Leibenluft E, Lieb R, Bauer M, Pfennig A, Mood episodes and mood disorders: patterns of incidence and conversion in the first three decades of life, Bipolar Disord, 11, 6, 637–49, September 2009, 19689506, 2796427, 10.1111/j.1399-5618.2009.00738.x, There is speculation as to whether this condition may occur with greater frequency in the general, untreated population; successful social function of these potentially high-achieving individuals may lead to being labeled as normal, rather than as individuals with substantial dysregulation.

Criteria and subtypes

(File:Bipolar_disorder_subtypes_comparison_between_Bipolar_I,_II_disorder_and_Cyclothymia.svg|thumb|Simplified graphical comparison of bipolar I, bipolar II and cyclothymiaWEB,weblink Bipolar disorder, Publishing, Harvard Health, Harvard Health, April 11, 2019, BOOK, Essentials of abnormal psychology., Durand, V. Mark., 2015, Cengage Learning, 978-1305633681, [Place of publication not identified], 884617637, {{Rp|267}})The DSM and the ICD characterize bipolar disorder as a spectrum of disorders occurring on a continuum. The DSM-5 lists three specific subtypes:
  • Bipolar I disorder: At least one manic episode is necessary to make the diagnosis;JOURNAL, Renk K, White R, Lauer BA, McSwiggan M, Puff J, Lowell A, Bipolar Disorder in Children, Psychiatry J, 2014, 928685, 928685, February 2014, 24800202, 3994906, 10.1155/2014/928685, depressive episodes are common in the vast majority of cases with bipolar disorder I, but are unnecessary for the diagnosis. Specifiers such as "mild, moderate, moderate-severe, severe" and "with psychotic features" should be added as applicable to indicate the presentation and course of the disorder.
  • Bipolar II disorder: No manic episodes and one or more hypomanic episodes and one or more major depressive episode. Hypomanic episodes do not go to the full extremes of mania (i.e., do not usually cause severe social or occupational impairment, and are without psychosis), and this can make bipolar II more difficult to diagnose, since the hypomanic episodes may simply appear as periods of successful high productivity and are reported less frequently than a distressing, crippling depression.
  • Cyclothymia: A history of hypomanic episodes with periods of depression that do not meet criteria for major depressive episodes.JOURNAL, Van Meter AR, Youngstrom EA, Findling RL, Cyclothymic disorder: a critical review, Clin Psychol Rev, 32, 4, 229–43, June 2012, 22459786, 10.1016/j.cpr.2012.02.001,
When relevant, specifiers for peripartum onset and with rapid cycling should be used with any subtype. Individuals who have subthreshold symptoms that cause clinically significant distress or impairment, but do not meet full criteria for one of the three subtypes may be diagnosed with other specified or unspecified bipolar disorder. Other specified bipolar disorder is used when a clinician chooses to provide an explanation for why the full criteria were not met (e.g., hypomania without a prior major depressive episode).

Rapid cycling

Most people who meet criteria for bipolar disorder experience a number of episodes, on average 0.4 to 0.7 per year, lasting three to six months.JOURNAL, Angst J, Sellaro R, Historical perspectives and natural history of bipolar disorder, Biological Psychiatry, 48, 6, 445–457, 2000, 11018218, 10.1016/s0006-3223(00)00909-4, Rapid cycling, however, is a course specifier that may be applied to any of the above subtypes. It is defined as having four or more mood disturbance episodes within a one-year span and is found in a significant proportion of individuals with bipolar disorder.JOURNAL, Muneer A, Treatment of the depressive phase of bipolar affective disorder: a review, J Pak Med Assoc, 63, 6, 763–9, June 2013, 23901682, These episodes are separated from each other by a remission (partial or full) for at least two months or a switch in mood polarity (i.e., from a depressive episode to a manic episode or vice versa). The definition of rapid cycling most frequently cited in the literature (including the DSM) is that of Dunner and Fieve: at least four major depressive, manic, hypomanic or mixed episodes are required to have occurred during a 12-month period.JOURNAL, Bauer M, Beaulieu S, Dunner DL, Lafer B, Kupka R, Rapid cycling bipolar disorder – diagnostic concepts, Bipolar Disorders, 10, 1 Pt 2, 153–62, February 2008, 18199234, 10.1111/j.1399-5618.2007.00560.x, Ultra-rapid (days) and ultra-ultra rapid or ultradian (within a day) cycling have also been described.JOURNAL, Tillman R, Geller B, Definitions of Rapid, Ultrarapid, and Ultradian Cycling and of Episode Duration in Pediatric and Adult Bipolar Disorders: A Proposal to Distinguish Episodes from Cycles, Journal of Child and Adolescent Psychopharmacology, 13, 3, 267–271, 2003, 14642014, 10.1089/104454603322572598, The literature examining the pharmacological treatment of rapid cycling is sparse and there is no clear consensus with respect to its optimal pharmacological management.JOURNAL, Fountoulakis KN, Kontis D, Gonda X, Yatham LN, A systematic review of the evidence on the treatment of rapid cycling bipolar disorder, Bipolar Disord, 15, 2, 115–37, March 2013, 23437958, 10.1111/bdi.12045,weblink


Attempts at prevention of bipolar disorder have focused on stress (such as childhood adversity or highly conflictual families) which, although not a diagnostically specific causal agent for bipolar, does place genetically and biologically vulnerable individuals at risk for a more severe course of illness.JOURNAL, Miklowitz DJ, Chang KD, Prevention of bipolar disorder in at-risk children: theoretical assumptions and empirical foundations., Development and Psychopathology, 20, 3, 881–97, Summer 2008, 18606036, 10.1017/s0954579408000424, 2504732, There has been debate regarding the causal relationship between usage of cannabis and bipolar disorder.JOURNAL, Khan MA, Akella S, Cannabis-Induced Bipolar Disorder with Psychotic Features: A Case Report, Psychiatry (Edgmont), 6, 12, 44–8, December 2009, 20104292, 2811144,


There are a number of pharmacological and psychotherapeutic techniques used to treat bipolar disorder. Individuals may use self-help and pursue recovery.Hospitalization may be required especially with the manic episodes present in bipolar I. This can be voluntary or (local legislation permitting) involuntary (called civil or involuntary commitment). Long-term inpatient stays are now less common due to deinstitutionalization, although these can still occur.JOURNAL, Becker T, Kilian R, Psychiatric services for people with severe mental illness across western Europe: What can be generalized from current knowledge about differences in provision, costs and outcomes of mental health care?, Acta Psychiatrica Scandinavica, 113, 429, 9–16, 2006, 16445476, 10.1111/j.1600-0447.2005.00711.x, Following (or in lieu of) a hospital admission, support services available can include drop-in centers, visits from members of a community mental health team or an Assertive Community Treatment team, supported employment and patient-led support groups, intensive outpatient programs.

Psychotherapy is aimed at alleviating core symptoms, recognizing episode triggers, reducing negative expressed emotion in relationships, recognizing prodromal symptoms before full-blown recurrence, and, practicing the factors that lead to maintenance of remission.Lam et al., 1999; Miklowitz & Goldstein, 1997; Frank, 2005.{{full citation needed|date=February 2012|reason=no citations for these references}}{{sfn|Leahy|Johnson|2003}}{{sfn|Basco|Rush|2005}} Cognitive behavioral therapy, family-focused therapy, and psychoeducation have the most evidence for efficacy in regard to relapse prevention, while interpersonal and social rhythm therapy and cognitive-behavioral therapy appear the most effective in regard to residual depressive symptoms.

Mood stabilizers

Lithium and the anticonvulsants carbamazepine, lamotrigine, and valproic acid are used as mood stabilizers to treat bipolar disorder. These mood stabilizers are used for long-term mood stabilization but have not demonstrated the ability to quickly treat acute bipolar depression. Lithium is preferred for long-term mood stabilization.JOURNAL, Geddes JR, Miklowitz DJ, Treatment of bipolar disorder, Lancet, 381, 9878, 1672–82, May 11, 2013, 23663953, 10.1016/S0140-6736(13)60857-0, 3876031, Carbamazepine effectively treats manic episodes, with some evidence it has greater benefit in rapid-cycling bipolar disorder, or those with more psychotic symptoms or a more schizoaffective clinical picture.

Antipsychotic medications are effective for short-term treatment of bipolar manic episodes and appear to be superior to lithium and anticonvulsants for this purpose.

In cases of comorbid ADHD and bipolar, stimulants may help improve both conditions.BOOK, Hegerl, Ulrich, Sander, Christian, Hensch, Tilman, Frodl, Thomas, vanc, Systems Neuroscience in Depression, Elsevier Science., 353, Arousal Regulation in Affective Disorders, In conclusion, stimulants in bipolar disorder seem to be relatively safe, and there are even several case reports suggesting rapid antimanic effects of psychostimulants (Beckmann & Heinemann, 1976; Garvey, Hwang, Teubner-Rhodes, Zander, & Rhem, 1987; Max, Richards, & Hamdanallen, 1995). In a study by Bschor, Müller-Oerlinghausen, and Ulrich (2001), improvement of manic symptoms occurred about 2   h after oral intake of methylphenidate in a manic patient with signs of unstable EEG-vigilance regulation. Three months later, when the patient was admitted anew, a rapid antimanic effect was again shown after re-exposition to methylphenidate,

Alternative medicine

Several studies have suggested that omega-3 fatty acids may have beneficial effects on depressive symptoms, but not manic symptoms. However, only a few small studies of variable quality have been published and there is not enough evidence to draw any firm conclusions.JOURNAL, Montgomery P, Richardson AJ, Omega-3 fatty acids for bipolar disorder, The Cochrane Database of Systematic Reviews, 2, CD005169, April 2008, 18425912, 10.1002/14651858.CD005169.pub2, Montgomery, Paul, Currently, there is simply not enough existing evidence, and what evidence is currently available is of such a varied and often-times questionable nature that no reliable conclusions may be drawn., JOURNAL, Ciappolino V, Delvecchio G, Agostoni C, Mazzocchi A, Altamura AC, Brambilla P, The role of n-3 polyunsaturated fatty acids (n-3PUFAs) in affective disorders, Journal of Affective Disorders, 224, 32–47, December 2017, 28089169, 10.1016/j.jad.2016.12.034, Review,


A lifelong condition with periods of partial or full recovery in between recurrent episodes of relapse, bipolar disorder is considered to be a major health problem worldwide because of the increased rates of disability and premature mortality. It is also associated with co-occurring psychiatric and medical problems, and high rates of initial under- or misdiagnosis, causing a delay in appropriate treatment interventions and contributing to poorer prognoses. After a diagnosis is made, it remains difficult to achieve complete remission of all symptoms with the currently available psychiatric medications and symptoms often become progressively more severe over time.{{citation|title=Staging Models in Bipolar Disorder: A Systematic Review of the Literature|last=Muneer|first=Ather|date=2016|journal=Clinical Psychopharmacology & Neuroscience|volume=14|issue=2|pages=117–30|doi=10.9758/cpn.2016.14.2.117|pmc=4857867|pmid=27121423}}Compliance with medications is one of the most significant factors that can decrease the rate and severity of relapse and have a positive impact on overall prognosis. However, the types of medications used in treating BD commonly cause side effects and more than 75% of individuals with BD inconsistently take their medications for various reasons.{{citation|title=Diagnosis and Treatment of Bipolar Disorders in Adults: A Review of the Evidence on Pharmacologic Treatments|last=Jann|first=Michael W.|year=2014|journal=American Health & Drug Benefits|volume=7|issue=9|pages=489–499|pmc=4296286|pmid=25610528}}Of the various types of the disorder, rapid cycling (four or more episodes in one year) is associated with the worst prognosis due to higher rates of self-harm and suicide. Individuals diagnosed with bipolar who have a family history of bipolar disorder are at a greater risk for more frequent manic/hypomanic episodes. Early onset and psychotic features are also associated with worse outcomes,JOURNAL, Kennedy KP, Cullen KR, DeYoung CG, Klimes-Dougan B, The genetics of early-onset bipolar disorder: A systematic review, Journal of Affective Disorders, 184, 1–12, September 2015, 26057335, 5552237, 10.1016/j.jad.2015.05.017, JOURNAL, Serafini G, Pompili M, Borgwardt S, Houenou J, Geoffroy PA, Jardri R, Girardi P, Amore M, Brain changes in early-onset bipolar and unipolar depressive disorders: a systematic review in children and adolescents, European Child & Adolescent Psychiatry, 23, 11, 1023–41, November 2014, 25212880, 10.1007/s00787-014-0614-z, as well as subtypes that are nonresponsive to lithium.Early recognition and intervention also improve prognosis as the symptoms in earlier stages are less severe and more responsive to treatment. Onset after adolescence is connected to better prognoses for both genders, and being male is a protective factor against higher levels of depression. For women, better social functioning prior to developing bipolar disorder and being a parent are protective towards suicide attempts.JOURNAL, Maciukiewicz M, Pawlak J, Kapelski P, Łabędzka M, Skibinska M, Zaremba D, Leszczynska-Rodziewicz A, Dmitrzak-Weglarz M, Hauser J, Can Psychological, Social and Demographical Factors Predict Clinical Characteristics Symptomatology of Bipolar Affective Disorder and Schizophrenia?, Psychiatr Q, 87, 3, 501–13, 2016, 26646576, 4945684, 10.1007/s11126-015-9405-z,


People with bipolar disorder often experience a decline in cognitive functioning during (or possibly before) their first episode, after which a certain degree of cognitive dysfunction typically becomes permanent, with more severe impairment during acute phases and moderate impairment during periods of remission. As a result, two-thirds of people with BD continue to experience impaired psychosocial functioning in between episodes even when their mood symptoms are in full remission. A similar pattern is seen in both BD-I and BD-II, but people with BD-II experience a lesser degree of impairment.JOURNAL, Tsitsipa E, Fountoulakis KN, The neurocognitive functioning in bipolar disorder: a systematic review of data, Annals of General Psychiatry, 14, 42, December 1, 2015, 26628905, 4666163, 10.1186/s12991-015-0081-z, Cognitive deficits typically increase over the course of the illness. Higher degrees of impairment correlate with the number of previous manic episodes and hospitalizations, and with the presence of psychotic symptoms.JOURNAL, Bortolato B, Miskowiak KW, Köhler CA, Vieta E, Carvalho AF, Cognitive dysfunction in bipolar disorder and schizophrenia: a systematic review of meta-analyses, Neuropsychiatric Disease and Treatment, 11, 3111–25, 2015, 26719696, 4689290, 10.2147/NDT.S76700, Early intervention can slow the progression of cognitive impairment, while treatment at later stages can help reduce distress and negative consequences related to cognitive dysfunction.Despite the overly ambitious goals that are frequently part of manic episodes, symptoms of mania undermine the ability to achieve these goals and often interfere with an individual's social and occupational functioning. One third of people with BD remain unemployed for one year following a hospitalization for mania.{{citation|title=Mania and Dysregulation in Goal Pursuit: A Review|last=Johnson|first=Sheri L.|date=2005|journal=Clinical Psychology Review|volume=25|issue=2|pages=241–62|doi=10.1016/j.cpr.2004.11.002|pmc=2847498|pmid=15642648}} Depressive symptoms during and between episodes, which occur much more frequently for most people than hypomanic or manic symptoms over the course of illness, are associated with lower functional recovery in between episodes, including unemployment or underemployment for both BD-I and BD-II. However, the course of illness (duration, age of onset, number of hospitalizations, and presence or not of rapid cycling) and cognitive performance are the best predictors of employment outcomes in individuals with bipolar disorder, followed by symptoms of depression and years of education.JOURNAL, Tse S, Chan S, Ng KL, Yatham LN, Meta-analysis of predictors of favorable employment outcomes among individuals with bipolar disorder, Bipolar Disord, 16, 3, 217–29, 2014, 24219657, 10.1111/bdi.12148,

Recovery and recurrence

A naturalistic study from first admission for mania or mixed episode (representing the hospitalized and therefore most severe cases) found that 50 percent achieved syndromal recovery (no longer meeting criteria for the diagnosis) within six weeks and 98 percent within two years. Within two years, 72 percent achieved symptomatic recovery (no symptoms at all) and 43 percent achieved functional recovery (regaining of prior occupational and residential status). However, 40 percent went on to experience a new episode of mania or depression within 2 years of syndromal recovery, and 19 percent switched phases without recovery.JOURNAL, Tohen M, Zarate CA, Hennen J, Khalsa HM, Strakowski SM, Gebre-Medhin P, Salvatore P, Baldessarini RJ, The McLean-Harvard First-Episode Mania Study: Prediction of recovery and first recurrence, The American Journal of Psychiatry, 160, 12, 2099–2107, 2003, 14638578, 10.1176/appi.ajp.160.12.2099, 11381/1461461, Symptoms preceding a relapse (prodromal), specially those related to mania, can be reliably identified by people with bipolar disorder.JOURNAL, Jackson A, Cavanagh J, Scott J, A systematic review of manic and depressive prodromes, Journal of Affective Disorders, 74, 3, 209–217, 2003, 12738039, 10.1016/s0165-0327(02)00266-5, There have been intents to teach patients coping strategies when noticing such symptoms with encouraging results.JOURNAL, Lam D, Wong G, Prodromes, coping strategies and psychological interventions in bipolar disorders, Clinical Psychology Review, 25, 8, 1028–1042, 2005, 16125292, 10.1016/j.cpr.2005.06.005,

The word melancholia is derived from melas (), meaning "black", and chole (), meaning "bile" or "gall",{{sfn|Liddell|Scott|1980}} indicative of the term's origins in pre-Hippocratic humoral theory. Within the humoral theories, mania was viewed as arising from an excess of yellow bile, or a mixture of black and yellow bile. The linguistic origins of mania, however, are not so clear-cut. Several etymologies were proposed by the Ancient Roman physician Caelius Aurelianus, including the Greek word ania, meaning "to produce great mental anguish", and manos, meaning "relaxed" or "loose", which would contextually approximate to an excessive relaxing of the mind or soul.JOURNAL, Angst J, Marneros A, Bipolarity from ancient to modern times: conception, birth and rebirth, Journal of Affective Disorders, 67, 1–3, 3–19, December 2001, 11869749, 10.1016/S0165-0327(01)00429-3, There are at least five other candidates, and part of the confusion surrounding the exact etymology of the word mania is its varied usage in the pre-Hippocratic poetry and mythology.In the early 1800s, French psychiatrist Jean-Étienne Dominique Esquirol's lypemania, one of his affective monomanias, was the first elaboration on what was to become modern depression.JOURNAL, Borch-Jacobsen M, Which came first, the condition or the drug?, London Review of Books, 32, 19, 31–33, October 2010,weblink at the beginning of the 19th century with Esquirol's 'affective monomanias' (notably 'lypemania', the first elaboration of what was to become our modern depression), live,weblink" title="">weblink March 13, 2015, mdy-all, The basis of the current conceptualisation of bipolar illness can be traced back to the 1850s; In 1850, Jean-Pierre Falret presented a description to the Academy the Paris Psychiatric Society in the course of which he mentioned "circular insanity" (la folie circulaire, {{IPA-fr|la fɔli siʁ.ky.lɛʁ}}); the lecture was summarized in 1851 in the "Gazette des hôpitaux" ("Hospital Gazette").BOOK, Edward Shorter, A Historical Dictionary of Psychiatry,weblink 2005, New York, Oxford University Press, 978-0-19-517668-1, 165–166, Three years later, in 1854, Jules-Gabriel-François Baillarger (1809–1890) described to the French Imperial Académie Nationale de Médecine a biphasic mental illness causing recurrent oscillations between mania and melancholia, which he termed folie à double forme ({{IPA-fr|fɔli a dubl fɔʀm}}, "madness in double form").JOURNAL, Pichot P., 150e anniversaire de la Folie Circulaire, Circular insanity, 150 years on, Bulletin de l'Académie Nationale de Médecine, 188, 2, 275–284, 2004, 15506718, fr, 10.1016/S0001-4079(19)33801-4, Baillarger's original paper, "De la folie à double forme," appeared in the medical journal Annales médico-psychologiques (Medico-psychological annals) in 1854.These concepts were developed by the German psychiatrist Emil Kraepelin (1856–1926), who, using Kahlbaum's concept of cyclothymia,{{sfn|Millon|1996|p=290}} categorized and studied the natural course of untreated bipolar patients. He coined the term manic depressive psychosis, after noting that periods of acute illness, manic or depressive, were generally punctuated by relatively symptom-free intervals where the patient was able to function normally.{{citation|last=Kraepelin|first=Emil|year=1921|title=Manic–depressive Insanity and Paranoia|journal=The Indian Medical Gazette|volume=56|issue=4|pages=156–157|isbn= 978-0-405-07441-7|pmc=5166213}}The term "manic–depressive reaction" appeared in the first version of the DSM in 1952, influenced by the legacy of Adolf Meyer.{{sfn|Goodwin|Jamison|2007| loc=Chapter 1}} Subtyping into "unipolar" depressive disorders and bipolar disorders has its origin in Karl Kleist's concept – since 1911 – of unipolar and bipolar affective disorders, which was used by Karl Leonhard in 1957 to differentiate between unipolar and bipolar disorder in depression. These subtypes have been regarded as separate conditions since publication of the DSM-III. The subtypes bipolar II and rapid cycling have been included since the DSM-IV, based on work from the 1970s by David Dunner, Elliot Gershon, Frederick Goodwin, Ronald Fieve, and Joseph Fleiss.Bipolar Depression: Molecular Neurobiology, Clinical Diagnosis and Pharmacotherapy {{webarchive|url= |date=May 7, 2016 }} Carlos A.

A link between mental illness and professional success or creativity has been suggested, including in accounts by Socrates, Seneca the Younger, and Cesare Lombroso. Despite prominence in popular culture, the link between creativity and bipolar has not been rigorously studied. This area of study also is likely affected by confirmation bias. Some evidence suggests that some heritable component of bipolar disorder overlaps with heritable components of creativity. Probands of people with bipolar disorder are more likely to be professionally successful, as well as to demonstrate temperamental traits similar to bipolar disorder. Furthermore, while studies of the frequency of bipolar disorder in creative population samples have been conflicting, studies that have a positive finding report that full blown bipolar disorder is rare.BOOK, Akiskal, Hagop, Akiskal, Kareen, Lakshmi, Yatham, vanc, Bipolar Disorder: Clinical and Neurobiological Foundations, 83–89, Wiley, The Genius-Insanity Debate: Focus on Bipolarity, Temperament, Creativity and Leadership, 10.1002/9780470661277.ch9, 9780470661277, 2010,

Specific populations


File:Lithium carbonate.jpg|thumb|Lithium is the only medication approved by the FDA for treating mania in children]]In the 1920s, Emil Kraepelin noted that manic episodes are rare before puberty. In general, bipolar disorder in children was not recognized in the first half of the twentieth century. This issue diminished with an increased following of the DSM criteria in the last part of the twentieth century.JOURNAL, Anthony J, Scott P, Manic–depressive Psychosis in Childhood, Journal of Child Psychology and Psychiatry, 1, 53–72, 1960, 10.1111/j.1469-7610.1960.tb01979.x, The DSM5 does not specifically have bipolar disorder in children and instead refers to it as disruptive mood dysregulation disorder.WEB, Pediatric Bipolar Affective Disorder,weblink June 28, 2018, March 28, 2018, While in adults the course of bipolar disorder is characterized by discrete episodes of depression and mania with no clear symptomatology between them, in children and adolescents very fast mood changes or even chronic symptoms are the norm. Pediatric bipolar disorder is commonly characterized by outbursts of anger, irritability and psychosis, rather than euphoric mania, which is more likely to be seen in adults. Early onset bipolar disorder is more likely to manifest as depression rather than mania or hypomania.JOURNAL, Cosgrove VE, Roybal D, Chang KD, Bipolar depression in pediatric populations: epidemiology and management, Paediatr Drugs, 15, 2, 83–91, April 2013, 23529869, 10.1007/s40272-013-0022-8, The diagnosis of childhood bipolar disorder is controversial, although it is not under discussion that the typical symptoms of bipolar disorder have negative consequences for minors suffering them. The debate is mainly centered on whether what is called bipolar disorder in children refers to the same disorder as when diagnosing adults, and the related question of whether the criteria for diagnosis for adults are useful and accurate when applied to children. Regarding diagnosis of children, some experts recommend following the DSM criteria. Others believe that these criteria do not correctly separate children with bipolar disorder from other problems such as ADHD, and emphasize fast mood cycles. Still others argue that what accurately differentiates children with bipolar disorder is irritability. The practice parameters of the AACAP encourage the first strategy. American children and adolescents diagnosed with bipolar disorder in community hospitals increased 4-fold reaching rates of up to 40 percent in 10 years around the beginning of the 21st century, while in outpatient clinics it doubled reaching 6 percent. Studies using DSM criteria show that up to 1 percent of youth may have bipolar disorder.Treatment involves medication and psychotherapy.JOURNAL, Leibenluft E, Rich BA, Pediatric Bipolar Disorder, Annual Review of Clinical Psychology, 4, 163–187, 2008, 17716034, 10.1146/annurev.clinpsy.4.022007.141216,weblink Drug prescription usually consists in mood stabilizers and atypical antipsychotics. Among the former, lithium is the only compound approved by the FDA for children.JOURNAL, McClellan J, Kowatch R, Findling RL, Practice Parameter for the Assessment and Treatment of Children and Adolescents with Bipolar Disorder, Journal of the American Academy of Child & Adolescent Psychiatry, 46, 1, 107–125, 2007, 17195735, 10.1097/01.chi.0000242240.69678.c4, Work Group on Quality Issues, Psychological treatment combines normally education on the disease, group therapy and cognitive behavioral therapy. Chronic medication is often needed.Current research directions for bipolar disorder in children include optimizing treatments, increasing the knowledge of the genetic and neurobiological basis of the pediatric disorder and improving diagnostic criteria. Some treatment research suggests that psychosocial interventions that involve the family, psychoeducation, and skills building (through therapies such as CBT, DBT, and IPSRT) can benefit in a pharmocotherapy.JOURNAL, Fristad MA, MacPherson HA, Evidence-based psychosocial treatments for child and adolescent bipolar spectrum disorders, Journal of Clinical Child and Adolescent Psychology, 43, 3, 339–55, 2014, 23927375, 3844106, 10.1080/15374416.2013.822309, Unfortunately, the literature and research on the effects of psychosocial therapy on BPSD is scarce, making it difficult to determine the efficacy of various therapies. The DSM-5 has proposed a new diagnosis which is considered to cover some presentations currently thought of as childhood-onset bipolar.JOURNAL, Roy AK, Lopes V, Klein RG, Disruptive mood dysregulation disorder: a new diagnostic approach to chronic irritability in youth, The American Journal of Psychiatry, 171, 9, 918–24, September 2014, 25178749, 4390118, 10.1176/appi.ajp.2014.13101301,


There is a relative lack of knowledge about bipolar disorder in late life. There is evidence that it becomes less prevalent with age but nevertheless accounts for a similar percentage of psychiatric admissions; that older bipolar patients had first experienced symptoms at a later age; that later onset of mania is associated with more neurologic impairment; that substance abuse is considerably less common in older groups; and that there is probably a greater degree of variation in presentation and course, for instance individuals may develop new-onset mania associated with vascular changes, or become manic only after recurrent depressive episodes, or may have been diagnosed with bipolar disorder at an early age and still meet criteria. There is also some weak and not conclusive evidence that mania is less intense and there is a higher prevalence of mixed episodes, although there may be a reduced response to treatment. Overall, there are likely more similarities than differences from younger adults.JOURNAL, Vasudev A, Thomas A, 'Bipolar disorder' in the elderly: what's in a name?, Maturitas, 66, 3, 231–5, July 2010, 20307944, 10.1016/j.maturitas.2010.02.013, JOURNAL, Depp CA, Jeste DV, Bipolar disorder in older adults: A critical review, Bipolar Disorders, 6, 5, 343–367, 2004, 15383127, 10.1111/j.1399-5618.2004.00139.x, In the elderly, recognition and treatment of bipolar disorder may be complicated by the presence of dementia or the side effects of medications being taken for other conditions.JOURNAL, Trinh NH, Forester B, Bipolar Disorder in the Elderly: Differential Diagnosis and Treatment, Psychiatric Times, 24, 14, 2007,weblink live,weblink" title="">weblink June 21, 2009,
