分离性身份障碍英语作文Dissociative Identity Disorder: Understanding the Complex Phenomenon.Dissociative identity disorder (DID), previously known as multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct personality states or identities that alternately take control of an individual's behavior. These distinct identities, known as alters, are often associated with different memories, emotions, and behaviors, which can be extremely disruptive and debilitating for those experiencing it. DID is a controversial diagnosis, and its existence has been hotly debated within the psychological community. However, it is recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as a valid condition that requires careful assessment and treatment.The etiology of DID is multifaceted and often involves a combination of genetic, neurobiological, andenvironmental factors. Trauma, particularly childhood abuse or neglect, is a common trigger for the development of DID. The repeated and severe psychological stress associated with such trauma can lead to the dissociation of memories, emotions, and even identity, resulting in the emergence of multiple alters. These alters may serve as coping mechanisms, allowing the individual to escape from the overwhelming emotional pain and memories associated with the trauma.The symptoms of DID can be diverse and vary among individuals. Common symptoms include memory loss or distortion, feelings of detachment or estrangement from oneself or one's environment, and the presence of distinct alters with their own identities, memories, and behaviors. These alters may have different names, ages, genders, and even personal histories. They may take control of the individual's behavior at different times, leading to confusion, discontinuity, and a sense of loss of control.The diagnosis of DID is challenging due to its complexity and the subjective nature of the symptoms. Itrequires a thorough assessment by a trained mental health professional, who must rule out other potential causes of the symptoms, such as schizophrenia, bipolar disorder, or malingering. DID is diagnosed based on the presence of at least two distinct alters, which recurrently take control of the individual's behavior, and significant memory loss, confusion, or discontinuity in the individual's self-perception, affect, or behavior.The treatment of DID is also complex and requires a multifaceted approach. Therapy, particularly psychotherapy, is a crucial component of treatment. Techniques such as cognitive-behavioral therapy (CBT) and psychodynamic therapy can help individuals gain insight into their condition, manage their symptoms, and develop healthier coping mechanisms. Medication may also be used to address comorbid conditions such as depression or anxiety.In addition to therapy, lifestyle changes can also be beneficial for individuals with DID. Establishing a regular sleep schedule, engaging in physical activities, and maintaining a healthy diet can help improve overall well-being and reduce stress. Support groups and peer-support networks can also provide a sense of community and understanding for those with DID.It is important to note that DID is a chronic condition that may require lifelong management. However, with the appropriate treatment and support, individuals with DID can lead fulfilling and productive lives. It is crucial to approach DID with an open and understanding mindset, recognizing that it is a real and debilitating condition that requires compassion and support.In conclusion, dissociative identity disorder is a complex psychological condition that requires careful assessment and treatment. It is characterized by the presence of two or more distinct alter egos thatalternately take control of an individual's behavior. The etiology of DID is multifaceted and often involves a combination of genetic, neurobiological, and environmental factors. The diagnosis is challenging due to its complexity and the subjective nature of the symptoms. Treatment involves a multifaceted approach, including psychotherapy,medication, and lifestyle changes. With the appropriate treatment and support, individuals with DID can lead fulfilling and productive lives.。

Bipolar and Related DisordersBipolar DisordersTo enhance the accuracy of diagnosis and facilitate earlier detection in clinical settings, Criterion A for manic and hypomanic episodes now includes an emphasis on changes in activity and energy as well as mood. The DSM-IV diagnosis of bipolar I disorder, mixed episode, requiring that the individual simultaneously meet full criteria for both mania and major depressive episode, has been removed. Instead, a new specifier, “with mixed features,” has been added that can be applied to episodes of mania or hypomania when depressive features are present, and to episodes of depression in the context of major depressive disorder or bipolar disorder when features of mania/hypomania are present. Other Specified Bipolar and Related DisorderDSM-5 allows the specification of particular conditions for other specified bipolar and related disorder, including categorization for individuals with a past history of a major depressive disorder who meet all criteria for hypomania except the duration criterion (i.e., at least 4 consecutive days). A second condition constituting an other specified bipolar and related disorder is that too few symptoms of hypomania are present to meet criteria for the full bipolar II syndrome, although the duration is sufficient at 4 or more days.Anxious Distress SpecifierIn the chapter on bipolar and related disorders and the chapter on depressive disorders, a specifier for anxious distress is delineated. This specifier is intended to identify patients with anxiety symptoms that are not part of the bipolar diagnostic criteria. Depressive DisordersDSM-5 contains several new depressive disorders, including disruptive mood dysregulation disorder and premenstrual dysphoric disorder. To address concerns about potential overdiagnosis and overtreatment of bipolar disorder in children, a new diagnosis, disruptive mood dysregulation disorder, is included for children up to age 18 years who exhibit persistent irritability and frequent episodes of extreme behavioral dyscontrol. Based on strong scientific evidence, premenstrual dysphoric disorder has been moved from DSM-IV Appendix B, “Criteria Sets and Axes Provided for Further Study,” to the main body of DSM-5. Finally, DSM-5 conceptualizes chronic forms of depression in a somewhat modified way. What was referred to as dysthymia in DSM-IV now falls under the category of persistent depressive disorder, which includes both chronic major depressive disorder and the previous dysthymic disorder. An inability to find scientifically meaningful differences between these two conditions led to their combination with specifiers included to identify different pathways to the diagnosis and to provide continuity with DSM-IV.Major Depressive DisorderNeither the core criterion symptoms applied to the diagnosis of major depressive episode nor the requisite duration of at least 2 weeks has changed from DSM-IV. Criterion A for a major depressive episode in DSM-5 is identical to that of DSM-IV, as is the requirement for clinically significant distress or impairment in social, occupational,or other important areas of life, although this is now listed as Criterion B rather than Criterion C. The coexistence within a major depressive episode of at least three manic symptoms (insufficient to satisfy criteria for a manic episode) is now acknowledged by the specifier “with mixed features.” The presence of mixed features in an episode of major depressive disorder in Highlights of Changes from DSM-IV-TR to DSM-5 • 5creases the likelihood that the illness exists in a bipolar spectrum; however, if the individual concerned has never met criteria for a manic or hypomanic episode, the diagnosis of major depressive disorder is retained.Bereavement ExclusionIn DSM-IV, there was an exclusion criterion for a major depressive episode that was applied to depressive symptoms lasting less than 2 months following the death of a loved one (i.e., the bereavement exclusion). This exclusion is omitted in DSM-5 for several reasons. The first is to remove the implication that bereavement typically lasts only 2 months when both physicians and grief counselors recognize that the duration is more commonly 1–2 years. Second, bereavement is recognized as a severe psychosocial stressor that can precipitate a major depressive episode in a vulnerable individual, generally beginning soon after the loss. When major depressive disorder occurs in the context of bereavement, it adds an additional risk for suffering, feelings of worthlessness, suicidal ideation, poorer somatic health, worse interpersonal and work functioning, and an increased risk for persistent complex bereavement disorder, which is now described with explicit criteria in Conditions for Further Study in DSM-5 Section III. Third, bereavement-related major depression is most likely to occur in individuals with past personal and family histories of major depressive episodes. It is genetically influenced and is associated with similar personality characteristics, patterns of comorbidity, and risks of chronicity and/or recurrence as non–bereavement-related major depressive episodes. Finally, the depressive symptoms associated with bereavement-related depression respond to the same psychosocial and medication treatments as non–bereavement-related depression. In the criteria for major depressive disorder, a detailed footnote has replaced the more simplistic DSM-IV exclusion to aid clinicians in making the critical distinction between the symptoms characteristic of bereavement and those of a major depressive episode. Thus, although most people experiencing the loss of a loved one experience bereavement without developing a major depressive episode, evidence does not support the separation of loss of a loved one from other stressors in terms of its likelihood of precipitating a major depressive episode or the relative likelihood that the symptoms will remit spontaneously.Specifiers for Depressive DisordersSuicidality represents a critical concern in psychiatry. Thus, the clinician is given guidance on assessment of suicidal thinking, plans, and the presence of other risk factors in order to make a determination of the prominence of suicide prevention in treatment planning for a given individual. A new specifier to indicate the presence of mixed symptoms has been added across both the bipolar and the depressive disorders, allowing for thepossibility of manic features in individuals with a diagnosis of unipolar depression. A substantial body of research conducted over the last two decades points to the importance of anxiety as relevant to prognosis and treatment decision making. The “with anxious distress” specifier gives the clinician an opportunity to rate the severity of anxious distress in all individuals with bipolar or depressive disorders.。

Mood disorders are a group of mental health conditions that affect the way a person feels, thinks, and behaves. They can cause a wide range of mood changes, from feeling sad or hopeless to feeling overly happy or energized. Here are some common types of mood disorders:1. Major Depressive Disorder (MDD): Also known as clinical depression, it is characterized by a persistent feeling of sadness and loss of interest in activities.2. Bipolar Disorder: Previously known as manic-depressive illness, this disorder involves episodes of depression and mania, which is an abnormally elevated mood.3. Dysthymia: A mild but long-lasting form of depression that can last for years.4. Cyclothymic Disorder: A milder form of bipolar disorder with alternating periods of depression and hypomania.5. Seasonal Affective Disorder (SAD): A type of depression that occurs at the same time each year, typically in the fall and winter months.6. Premenstrual Dysphoric Disorder (PMDD): A severe form of premenstrual syndrome (PMS) that can cause significant mood swings and depression.7. Postpartum Depression: A type of depression that many women experience after giving birth.These disorders are often treated with a combination of medication, therapy, and lifestyle changes. It's important for individuals experiencing mood disorders to seek professional help to manage their symptoms and improve their quality of life.。
双相情感障碍英语全称Bipolar Disorder, in English, is fully referred to as "Bipolar Affective Disorder" or "Manic-Depressive Illness." It is a mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). These episodes can vary in intensity and duration, and they can significantly impact a person'sability to function in daily life.The term "bipolar" comes from the Greek words "bi" meaning two and "polar" referring to the poles or extremes. It reflects the two contrasting emotional states thatindividuals with this disorder experience.Bipolar Disorder is further categorized into different types:1. Bipolar I Disorder: This is characterized by at least one manic episode, which may be preceded or followed by hypomanic or major depressive episodes.2. Bipolar II Disorder: This involves at least one major depressive episode and at least one hypomanic episode, but no full-blown manic episodes.3. Cyclothymic Disorder (or Cyclothymia): This is a milder form of the condition, with alternating hypomanic and depressive symptoms, but they are less severe than in Bipolar I or II.4. Other specified and unspecified bipolar and related disorders: These categories are used when the presentation of the symptoms doesn't fit neatly into the other categories.It's important to note that Bipolar Disorder is a serious medical condition that requires professional diagnosis and treatment. Treatment often includes a combination of medication, psychotherapy, and lifestyle changes to manage the symptoms effectively.。

双相情感障碍英语介绍Bipolar disorder, also known as manic-depressive illness, is a mental health condition characterized by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). These mood shifts can affect a person's ability to function in daily life. Here's an introduction to bipolar disorder in English:Bipolar Disorder: An OverviewBipolar disorder affects millions of people worldwide and is a complex mental health condition that requires careful management and understanding. It is not simply a case of having extreme ups and downs; rather, it is a chronic illness that can be life-altering for those who suffer from it.SymptomsThe symptoms of bipolar disorder are typically divided into two categories: manic episodes and depressive episodes.1. Manic Episodes:- Elevated mood, irritability, or both- Increased energy and activity levels- Rapid speech, racing thoughts, and easily distracted- Overconfidence or inflated self-esteem- Engaging in risky behaviors, such as reckless spending or impulsive decisions- Decreased need for sleep2. Depressive Episodes:- Persistent sadness, anxiety, or emptiness- Loss of interest or pleasure in activities once enjoyed - Feelings of hopelessness or worthlessness- Fatigue or loss of energy- Difficulty concentrating, making decisions, or remembering things- Changes in appetite and weight- Thoughts of death or suicideCausesThe exact cause of bipolar disorder is not known, but it is believed to involve a combination of genetic, environmental, and neurological factors. Research suggests that people with a family history of the disorder are more likely to develop it.TreatmentTreatment for bipolar disorder typically includes a combination of medication, therapy, and lifestyle changes. Medications such as mood stabilizers, antipsychotics, and antidepressants can help manage mood swings. Psychotherapy, including cognitive-behavioral therapy (CBT) and family-focused therapy, can provide additional support and coping strategies.Living with Bipolar DisorderManaging bipolar disorder is a lifelong process. It requires ongoing medical supervision, a strong support system, and personal commitment to treatment. Individuals with bipolar disorder can lead fulfilling lives by adhering to their treatment plans, maintaining a regular sleep schedule, avoiding alcohol and drug use, and engaging in regular exercise and healthy eating habits.ConclusionBipolar disorder is a serious mental health condition that can significantly impact a person's quality of life. However, with proper treatment and support, individuals with this disorder can lead stable and productive lives. It is important to approach the topic with empathy and understanding, recognizing the challenges faced by those who live with bipolar disorder.This introduction provides a basic understanding of bipolar disorder, its symptoms, potential causes, treatment options, and the importance of management for those affected by the condition.。
Surging living costs force Britons to work past retirement age生活成本飙升迫使英国人退休后继续工作The share of older UK workers planning to carry on working in their retirement has nearly doubled in two years due to rising living costs and insufficient pension savings, according to a survey from Abrdn.根据Abrdn的一项调查, 由于生活成本上升和养老金储蓄不足, 计划退休后继续工作的英国老年员工比例在两年内增加了近一倍。
The investment manager’s stark findings underscore the impact of soaring energy and food prices on household budgets, which is pressuring people’s finances as inflation hits a 30-year high.这家投资管理公司的严峻调查结果凸显出能源和食品价格飙升对家庭预算的影响。
随着通胀触及30年高点, 家庭预算正给人们的财务状况带来压力。

Conclusions The annual costto U K society attributable to bipolar disorder was estimated to be»2billion at1999/ 2000prices(estimated297000people withthe disorder).T en per cent ofthis cost is attributable to NHS resource use,4%to non-health-care resource use and86%to indirectcosts.Declaration of interest This study was funded by a grant from Janssen-Cilag, Saunderton,U K Bipolar disorder is a common illnesscharacterised by recurrent episodes of maniaand major depression.The lifetime preva-lence of bipolar disorder is between1%and2%(Bebbington&Ramana,1995).Moreover,bipolar disorder is often asso-ciated with other mental disorders,particu-larly alcoholism and substance misuse(Regier et al,1990).Bipolar disorder placesa substantial burden on primary andhealth-secondary health-carecare sectors as well asother statutory services(Office for NationalStatistics,1995;Onyett et al,1995);how-socio-ever,the socio-economiceconomic impact of bipolardisorder on UK society is unknown.Against this background we estimated theannual cost imposed by bipolar disorderon UK society.METHODPerspectiveThis evaluation estimated:(a)the annual costs of managing bipolardisorder from the perspective of theNational Health Service(NHS);(b)the annual costs resulting from bipolardisorder borne by other statutoryagencies,such as local authorities andthe criminal justice system;and(c)the indirect annual costs to society dueto unemployment,absenteeism fromwork and premature mortality.Primary care resource useThe DIN-link database contains infor-mation on0.9million live patients managedby approximately360general practitioners(GPs)in100nationally distributed generalpractices(using AAH Meditel System5clinical software,version5.7.x for UNIX;now System5,Torex Health,Bromsgrove,Worcestershire,UK).The database wasinterrogated to obtain the annual amountof primary care resource use(i.e.GPconsultations,GP-prescribed drugs andGP-GP-initiatedinitiated diagnostic tests)between1January1998and31December1998attri-butable to managing bipolar disorder.Patients were included if they had a noteentry of one of the following Read codes,together with an addition or amendmentto their case notes in the study year,indicat-ing that they were still registered with theirGP:hypomania/mania(E221);other manic±depressive psychoses(E22Z);affectivepsychoses(E22).The resource use estimatesderived from the DIN-link database wereextrapolated to the whole of the NHS bymultiplying by a factor of75,which takesinto account the size of the data-set popu-lation relative to that of the whole UKand the relative underrecording of certaindata items when the database is cross-refer-enced against other sources(Martin,1995).Secondary care in-patient resourceuseHospital in-patient data were based on theIBM Hospital Episode Statistics database,which contains information compiled fromthe statutory returns from the300trusts inEngland.The database was interrogated toobtain the annual number of hospital epi-sodes attributable to bipolar disorder inaccordance with the diagnostic codes ofICD±10(World Health Organization,1992)(i.e.F31.0±F31.9for1995/96to1997/98).Patients were included in thedata-set if they had a primary diagnosis ofbipolar disorder between1April1995and31March1998.Results were extrapo-lated to the whole UK by multiplying by1.2(i.e.the ratio of the population of the UK tothat of England).Other health care resource usePublished sources were used to provideinformation on resource utilisation bypsychiatric patients using NHS day hospitals(Department of Health,1999a),out-patientservices(Department of Health,1999b),community mental health teams(CMHTs;Onyett et al,1995)and special(high-security)hospitals(Department of Health,2000a,c).This was supplemented with informationobtained from interviews with ten NHSconsultant psychiatrists who had experienceof people with bipolar disorder.Personal social service resourceuse and the criminal justice systemData were obtained on resource utilisationby people with bipolar disorder using227HIB R I T I S H J O UR N A L O F P S YC H I AT RY(2002),180,227^233Annual cost of bipolar disorder to UK society ROBEN DAS GUPTA and JULIAN F.GUESTD ADA SGUP TA&GUE S Tresidential services(D.Chisholm,personal communication,1999),the criminal justice system(Stationery Office,2000a)and non-NHS day care facilities(Department of Health,1998),the latter being supplemen-ted with information obtained from tele-phone interviews with managers at seven non-NHS day care facilities. Resource costsUnit resource costs were obtained(D. Chisholm,personal communication, 1999;Netten et al,1999;Haymarket Publications,2000;Stationery Office, 2000b)and,where necessary,uprated to 1999/2000prices using the Health Service Inflation Index(Netten et al,1999).By assigning these costs to the resource use estimates,the annual direct cost attributa-ble to bipolar disorder was calculated at 1999/2000prices.Indirect resource use and costs The indirect cost arising from excess un-employment(Gareth Hill et al,1996), absenteeism from work(Lepine et al, 1997)and suicide(Sharma&Markar, 1994)among individuals with bipolar dis-order was estimated using the human capital approach(Drummond et al,1998),by applying the current annual average wage (Office for National Statistics,2000)to the estimated number of people with bipolar disorder absent from work as a result of morbidity and mortality.A6% annual discount rate was applied to the indirect costs of unemployment arising from people with bipolar disorder who commit suicide in the study year and,there-fore,who are absent from the workforce in subsequent years.Sensitivity analysisUnivariate sensitivity analyses tested the robustness of the study results to changes in resource use activity affecting health-care,non-health-care and indirect costs. RESULTSNational Health Service resource useThe DIN-link databaseThe DIN-link database contained data on 1807patients with bipolar disorder in 1998,equivalent to approximately 136000people with bipolar disorder being registered with a GP during that year.The mean age of people with bipolar disorderin the DIN-link data-set was54years.Ofthese,62%were female and38%weremale.Additionally,patients aged521years accounted for51%of the totalnumber of patients in the DIN-link data-set.GP consultationsBased on all the people with bipolardisorder in the DIN-link database,it wasestimated that there were315000GP con-attrisultations attributablebutable to bipolar disorderanduring1998.Hence,the annualnual cost ofGP consultations attributable to bipolardisorder was estimated to be£5.2million.GP-prescribed drugsFifty-eight per cent of patients in the DIN-link data-set received medication forbipolar disorder prescribed by their GPduring1998.This corresponds to an esti-mated79125patients receiving approxi-mately 1.2million GP-prescribed itemsduring the study year(Table1).TheseGP-prescribed drugs cost£8.5million.The mean annual cost of GP-prescribedmedication was£107per patient receivingmedication.This corresponds to a meanannual cost of£249per GP and£809pergeneral practice for medication for bipolardisorder.GP-initiated testsPeople with bipolar disorder undergo amean111000tests per year.These includeblood drug levels,biochemistry tests,thyroid function tests and haematology tests,costing the NHS£1.2million annually.In-patient episodesBetween1April1997and31March1998there were12400annual hospital episodesfor bipolar disorder in the UK,costing£69million.These episodes accounted for4%of the290019annual episodes for mentalhealth(Department of Health,2000a).From the interviews it was estimated thatabout30%of these episodes would resultin a patient being transported to a hospitalby ambulance,costing the

was greater among the25-to34-year age group,at seven episodes per year per100patients(equivalent to almost two-thirds of all the in-patient episodes), and was seven times greater than the annual number of episodes per patient in the516-and484-year age groups.Gen-erally,the annual number of hospital in-patient episodes per patient decreased with age among patients over34years of age.Additionally,the percentage of episodes associated with manic and hypo-manic symptoms decreased with age.Con-versely,proportionally more episodes were associated with depressive symptoms as patients'age increased.Out-patient and ward attendances Approximately2million annual psychiatric out-patient attendances are conducted under the auspices of mental illness and psychiatry of old age in the UK(Depart-ment of Health,1999b),of which14% was estimated to be because of bipolar dis-order.Hence,it was estimated that a mean 277000attendances a year are attributable to bipolar disorder,costing£28.5million.There are a mean96000annual psychiatric ward attendances in the UK (Department of Health,1999b),of which 5%was estimated to be because of bipolar disorder.This suggests that there are a mean5000attendances a year attributable to bipolar disorder,costing£munity mental health team contactsThe annual cost of CMHTs in the UK wasestimated to be£380million.Fourteen percent

754000attendances a year,cost-ing £18.1million.Criminal justice systemWe were unable to find any published evi-dence that the incidence of either imprison-ment or people on remand was higher among those with bipolar disorder than in the general population.Therefore,this analysis assumed that the cost incurred by the criminal justice system attributable specifically to bipolar disorder is zero.Indirect societal costsIndirect costs due to excess unemployment among people with bipolar disorderThe prevalence of bipolar disorder in the UK was estimated to be 0.5%(Bebbington &Ramana,1995),which is similar to the lifetime risk and annual prevalence rates and equates to approximately 297000people with bipolar disorder in the UK annually.The unemployment rate among people with bipolar disorder was estimated to be 46%,of whom 60%are available for work (Gareth Hill et al ,1996).This compared with an unemployment rate among the general population in the UK in 1999/2000of 3%(Office for National Statistics,2000).Hence,an excess of76500people annually are unemployed as a result of having bipolar disorder.Therefore,the annual indirect cost due to excess unemployment among people with bipolar disorder was estimated to be £1510million at 1999/2000prices.Indirect costs due to absenteeism from work among people with bipolar disorderThe rate of excess absenteeism from work among those with major depression com-pared with those without depression was estimated to be about 9days over a 6-month period in the UK (Lepine et al ,1997).Assuming that all of these subjects were in full-time employment,this suggests an excess absenteeism rate of 8%.By assuming comparable absenteeism from work among the UK's estimated 96300people with bipolar disorder who are employed (Kind &Sorensen,1993),the associated indirect cost would be £152million per year at 1999/2000prices.Indirect costs due to suicideThe annual incidence of bipolar disorder is0.009%and 0.0096%for males and females,respectively (Bebbington &Ramana,1995).Hence,there are 4454new cases of bipolar disorder diagnosed in the UK annually.The suicide rate among people with bipolar disorder is 1.5%annually for the first 10years following diagnosis (Sharma &Markar,1994).This equates to an excess of 640suicides because of bipolar disorder annually,with an associated indirect cost of £179million undiscounted or £109million discounted.Indirect costs due to carersA review of the published literature did not identify any evidence that there was a higher unemployment rate among carers than the general population;therefore,it was estimated that there are no indirect costs specifically attributable to carers of people with bipolar disorder.T otal annual societal cost of bipolar disorderThe total annual societal cost of bipolar disorder in 297000people was estimated to be £2055million annually (Table 5)or approximately £6919per person with bipolar disorder.Sensitivity analysesHealth care

the annual number of in-patient episodes and CMHT contacts would reduce the annual NHS cost of managing bipolar disorder by18%and 13%,respectively.However,the annual NHS cost is not sensitive to changes in the use of any other health care resource. Non-health-care direct costsSensitivity analyses(Table7)showed that doubling of the annual number of resi-dential places would increase the annual non-health-care cost of managing bipolar disorder by79%.Conversely,halving the annual number of residential places would reduce the annual non-health-care cost of managing bipolar disorder by39%.The annual non-health-care cost attributable to bipolar disorder is also sensitive to the assumptions pertaining to the use of the criminal justice system by people with bipolar disorder.If people with bipolar disorder made twice as much use of the criminal justice system as the general popu-lation,the annual non-health-care cost of managing bipolar disorder would increase by91%.Conversely,if people with bipolar disorder made half as much use of thecriminal justice system as the general popu-lation,the annual non-health-care cost ofmanaging bipolar disorder would decreaseby45%.However,the annual non-health-care cost of managing bipolar

theframework in which decisions aboutresource allocation are made.However,cost of illness studies,unlike cost-effective-ness and cost utility studies,are unable todirectly inform decisions about the effec-tive allocation of resources to fund parti-cular treatments or strategies.UncertaintyIn this analysis there is considerable un-certainty surrounding the prevalence ofbipolar disorder in the UK because of thelack of robust epidemiological surveys.Community-based psychiatric surveys inother countries estimate the total preva-lence of bipolar disorder to be1.0±2.5%,which is substantially higher than the numberof people treated for bipolar disorder(Beb-bington&Ramana,1995).Also,there maybe a high level of unmet need,althoughsome patients may develop coping strategiesor endure symptoms below the thresholdsfor treatment,given the current risk±benefitratios of available drugs.Finally,the varia-tion in diagnostic threshold can contributeto the uncertainty surrounding the prevalenceof bipolar disorder(Akiskal,1996).This analysis used interviews withpsychiatrists and managers of day carefacilities to estimate the percentage of theirworkload that was associated withmanaging people with bipolar disorder.Inthe hierarchy of evidence,such expert opin-ion is the least reliable compared with,forexample,randomised control trials(Stevens&Raftery,1994),but in the absence ofrelevant published data this was the onlysuitable method with which to model theseresource items.However,the estimatedpercentage of psychiatric out-patient work-load and CMHT workload attributable tobipolar disorder was comparable to thatreported by others(Onyett et al,1995;National Health Service in Scotland,1999).The prevalence of bipolar disorderamong patients in the DIN-link databasewas about0.25%.This was comparablewith the0.5%prevalence assumed in ourstudy(Bebbington&Ramana,1995).However,some patients may be managedalmost exclusively in secondary care,whereas others may not receive any healthcare.Furthermore,some people with bi-polar disorder may have been misdiagnosedunder a Read code that was not included inthe DIN-link data-set.The estimated prev-alence of people with bipolar

attributable to bipolar disorder is most sensitive to changes in the number of hospital admis-sions and CMHT contacts.However,there is little uncertainty about the annual num-ber of hospital admissions,which was derived from statutory Department of Health returns,although some people with bipolar disorder may have been excluded from our analysis,such as those who have only one manic episode not followed by a depressive episode.The estimated cost of CMHT contacts made use of the survey by Onyett et al(1995),which examined the organisation and operation of CMHTs in England.The structure of CMHTs may have changed since this survey was per-formed,but we were unable to find more recent published data on the structure of CMHTs to inform our analysis.Therefore, there remains some uncertainty surround-ing the cost of CMHT contacts pertaining to bipolar disorder.The annual non-health-care cost attributable to bipolar dis-order is most sensitive to changes in the number of residential places.However, there is little uncertainty about the annual number of residential places,which was derived from a database used in a study by Chisholm(D.Chisholm,personal communication,1999).The annual non-health-care cost is also sensitive to changes in the assumptions about the number of contacts made by people with bipolar dis-order with the criminal justice system.A Swiss study suggested that people with bipolar disorder were between two and three times more likely to engage in criminal activity than the general popu-lation(Modestin et al,1997).However, we found no evidence suggesting an in-creased risk of imprisonment among people with bipolar disorder in the UK.This dis-crepancy is worthy of further investigation.The annual indirect cost attributable to bipolar disorder was sensitive to changes in the number of unemployed people,which was based on a survey of those in the Manic Depression Fellowship.However,the membership of the Fellowship may not be representative of all people with bipolar disorder.The baseline indirect costs in our study relate to people receiving treatment for bipolar disorder.Including untreated cases could substantially increase the indirect costs.However,because such peoplehave not presented to the medical services,they may not exhibit the same level of mor-bidity and mortality as those who do present.Nevertheless,they may still endure reducedfunctioning and accrue costs.We estimated that640people withbipolar disorder commit suicide annually.This is equivalent to about11%of the5905suicides in the UK per year(Ray etal,1998).Additionally,in one survey of peo-ple with bipolar disorder,47%reported atleast one attempted suicide(Gareth Hill,etal,1996).In comparison,the annual numberof deaths because of depression was esti-mated to be2600(Gareth Hill et al,1996).Study limitationsPrimary care resource use was based on theDIN-link database.However,limitations indiagnostic categories may mean that somepatients included in the data-set may havebeen suffering from unipolar psychosis.Nevertheless,it was assumed that allpatients with a diagnostic code of`affectivepsychosis'suffer from bipolar disorder.Furthermore,patients with other conditions,such as schizophrenia and schizoaffectivedisorder,may have been included under thediagnostic categories for`mania and hypo-mania',reflecting the difficulties in makinga differential diagnosis for this disorder.The cost of drugs used to treat bipolardisorder constitutes less than2%of the totalcost of GP prescribing for all psychiatricconditions(Department of Health,2000d)and about5%,14%and14%of generalpsychiatric in-patient,out-patient andgeneral community team costs,respectively(Department of Health,2000d).Treatmentchoices are particularly important inpatients with bipolar disorder where com-pliance with conventional maintenancetreatment is low(Keck et al,1997).Someatypical antipsychotics have been shownto have antimanic properties(Tohen&Grundy,1999;Keck et al,2000)and a low-er risk of extrapyramidal symptoms than isassociated with typical antipsychotics(Miller et al,2001),potentially leading toimproved compliance.The cost of drugsprescribed by psychiatrists in out-patientclinics has not been included in the presentanalysis.However,because most drugs areprescribed and dispensed in the community,this is unlikely to lead to a substantial dif-ference in the annual drug cost.Moreover,the estimated annual primary care drug costof£8.5million for people with bipolardisorder is small compared,for example,with the drug costs for schizophrenia forEngland in1992/93.These were estimatedto be about£32million(£39million at1999/2000prices)(Knapp,1997).A number of services have not beencosted in this study,including a work re-habilitation scheme provided by the NHS,referrals to either a psychotherapist orclinical psychologist and attendances at adrug or alcohol dependency service.Theassociated costs of these are likely to beproportionally very low and within oursensitivity analyses.All these services areprovided within the NHS and form partof the care provided by out-patient clinics,CMHTs or day hospitals,and our baselineestimates are likely to include some of thesecosts.The analysis also excluded the intan-gible costs of patients and their families.The psychological burden of living with bi-polar disorder and its disruptive effect ondaily living affects the usual activity ofpatients and their families(Onyett et al,1995).Such activity may not involve paidemployment and is difficult to quantify.Comparison with schizophreniaCompared with schizophrenia,bipolar dis-order is a neglected disease.This is true ifone compares research output in academicjournals on the one hand and NHS plan-ning documents on the other.The presentstudy illustrates that bipolar disorder costsless than schizophrenia:£2billion com-pared with£3.7billion at1999/2000prices.In-patient care for schizophreniaaccounts for over90%of the annual directhealth care cost(£864million at1999/2000prices)(Knapp,1997),which was sub-stantially higher than the35%of theannual direct health care cost(£69million)attributable to in-patient care associatedwith bipolar disorder in our study.Allow-ing for the difference in time between thetwo studies,this difference suggests that,despite being possibly related conditions(Goodwin&Jamison,1990;Maziade et al,1995),treatment patterns differ substantially.ACKNOWLEDGEMENTSThe authors thank the following psychiatrists
