Bipolar disorder in Asia: Illness course and contributing factors

BACKGROUND

Epidemiological studies analysing the course of Bipolar Disorder (BD) are relatively rare in the Asian context, contributing to the uncertainty regarding the prevalent course patterns and factors influencing such patterns. The current review identifies the regional characteristics of BD course patterns and the associated factors.

METHODS

A review of the existing literature was done using 'PubMed' and 'Cochrane' databases which yielded 145 studies including those from all 48 Asian countries. Relevant discussions from the Western literature were incorporated.

RESULTS

Regional and cross-national studies reveal a mania-predominant course in BD in Asian countries. Prolonged depressive episodes and comorbid anxiety disorders worsen the course of BD-II. Certain risk factors such as the young age of onset and greater episode frequency are useful predictors of bipolar diatheses. Substance use disorder comorbidity is more prevalent in males whereas depression and suicidal behaviours are more frequent in females with BD. Comorbid anxiety and personality disorders also encumber the illness course. Logistic reasons and ignorance of side-effects were specifically associated with poor adherence. An 'eveningness' chronotype and poor sleep quality were associated with frequent recurrences. Seasonal patterns vary among men and women, especially for depressive episodes.

LIMITATIONS

The effects of treatment and childhood BD course features were not discussed.

CONCLUSIONS

There are region-specific characteristics in bipolar illness course and factors influencing such course patterns compared to the rest of the World. Future research from Asia shall attempt to study the neurobiological underpinnings of such characteristics and plan appropriate strategies to address the same.

Poor response to treatment: beyond medication

In psychiatry, one of the main factors contributing to poor response to pharmacological treatment is adherence. Noncompliance with maintenance treatments for chronic illnesses such as schizophrenia and affective disorders can exceed 50%, Poor adherence can be due to drug-related factors (tolerance, complexity of prescription, side effects, or cost), patient-related variables (illness symptoms, comorbidity, insight capacity, belief system, or sociocultural environment), and physician-related factors (communication or psychoeducational style). Psychosocial treatments must be used in conjunction with medication during the maintenance phase to improve adherence to treatment and to achieve - through the management of psychological variables - better social, work, and family functioning. This article reviews the concepts of adherence and noncompliance, and their impact on maintenance treatments, as well as the effect of dealing with psychosocial factors in psychiatric treatment.

Psycho-social outcomes for persons with bipolar-I disorder: Eight-year follow-up of a rural cohort from south India

BACKGROUND

Assess psycho-social outcomes in a rural cohort of patients with bipolar-I disorder (BD).

METHODS

Detailed evaluations were performed using the Longitudinal Interval Follow-up Evaluation (LIFE) assessments of community-based BD patients in southern India. Several subjective and objective outcome measures were examined.

RESULTS

Only half the cohort could be described as having a good overall outcome, with persistent difficulties in inter-personal relationships in a substantial proportion of patients. Separation or divorce, or co-morbid alcohol dependence impacted a higher proportion of female patients compared to males.

CONCLUSIONS

In spite of the small cohort size, this longitudinal study indicates mixed outcomes for BD patients in this setting, with several patients showing enduring psycho-social and global impairments. Even though symptomatic recovery for BD patients might be better in developing countries compared to those observed in developed nations, the notion of better psycho-social outcomes for BD in developing countries needs closer re-examination in larger cohorts.

Family focused treatment for patients with bipolar disorder in Turkey: a case series

Family-focused therapy (FFT) is a 9-month, 21-session structured psychoeducational treatment for bipolar disorder. Several US-based studies have documented its efficacy as adjunctive to medication for depression stabilization and relapse prevention. However, FFT has never been applied outside of the United States. The objective of this case series is to explore the applicability of FFT in a non-Western culture. Ten patients with bipolar disorder and their family members attended the 9-month FFT as adjunctive to pharmacotherapy in an outpatient specialty clinic in Izmir, Turkey. Patients improved in Global Assessment of Functioning Scores and Clinical Global Impression Scores from pre- to posttreatment. Case studies are given, which illustrate the differences between Western and non-Western families coping with bipolar disorder. FFT was easily applied to a Turkish sample with few changes in format or focus. Adaptations included substitution of oral for written therapeutic tasks or homework assignments. Randomized controlled trials are needed to test the clinical effectiveness of FFT and other psychosocial interventions in non-Western cultures.

Medication adherence and the use of long-acting antipsychotics in bipolar disorder

BACKGROUND

Adherence to treatment is a major determinant of outcome in bipolar disorder. Poor insight, attitudes towards treatment, and poor understanding of medications and the illness can all lead to reduced adherence. Nonadherence and partial adherence both also appear to play a significant role in relapse. Thirty to forty percent of patients with bipolar disorder who attempt to be adherent to treatment are actually only partially adherent. Clinicians frequently address the problem of poor adherence by adding an antipsychotic medication to the mood stabilizer regimen. The availability of a long-acting atypical antipsychotic raises the possibility of using this agent to prevent bipolar relapse.

METHODS

The literature on the use of depot antipsychotics in bipolar illness is reviewed, based on a search of PubMed and Ovid Medline.

RESULTS

No randomized, controlled trials of depot antipsychotics in bipolar illness have been performed. However, several case series and naturalistic trials that have used first generation agents suggest that depot antipsychotics are effective in reducing relapse in bipolar illness.

CONCLUSIONS

Depot antipsychotics, including long-acting first and second generation agents, can be important adjuncts in the long-term management of bipolar illness. Controlled trials with these agents in bipolar disorder are warranted.

Disability and its treatment in bipolar disorder patients

Bipolar disorders (BPD) are major, life-long psychiatric illnesses found in 2-5% of the population. Prognosis for BPD was once considered relatively favorable, but contemporary findings suggest that disability and poor outcomes are prevalent, despite major therapeutic advances. Syndromal recovery from acute episodes of mania or bipolar major depression is achieved in as many as 90% of patients given modern treatments, but full symptomatic recovery is achieved slowly, and residual symptoms of fluctuating severity and functional impact are the rule. Depressive-dysthymic-dysphoric morbidity continues in more than 30% of weeks in follow-up from initial episodes as well as later in the illness-course. As few as 1/3 of BPD patients achieve full social and occupational functional recovery to their own premorbid levels. Pharmacotherapy, though the accepted first-line treatment for BPD patients, is insufficient by itself, encouraging development of adjunctive psychological treatments and rehabilitative efforts to further limit morbidity and disability. Interpersonal, cognitive-behavioral, and psychoeducational therapies all show promise for improving symptomatic and functional outcomes. Much less is known about how these and more specific rehabilitative interventions might improve vocational functioning in BPD patients.

A systematic review evaluating health-related quality of life, work impairment, and healthcare costs and utilization in bipolar disorder

BACKGROUND

Bipolar disorder greatly impacts health-related quality of life (HRQoL), physical and social functioning, employment, and work productivity, and greatly increases health-care utilization and costs. Our objective was to characterize how bipolar disorder impacts HRQoL, work impairment, and health-care utilization and costs.

DATA SOURCES AND STUDY SELECTION

A systematic literature review was conducted to identify bipolar disorder studies of HRQoL, functioning, work impairment, and health-care utilization and costs. We searched Medline, ClinPSYC, and HealthSTAR for English-language articles published between January 1985 and November 2002 using MeSH headings and keywords. Additional articles were identified from references of relevant articles.

RESULTS

We identified 65 HRQoL articles, 14 work-impairment articles, and 28 utilization-and-care-cost articles. For all HRQoL instruments used, bipolar disorder patients' HRQoL was rated similarly to that of unipolar depression patients, and equal to or lower compared with patients with other chronic nonmental illnesses. Current treatments have been shown to improve HRQoL and physical and social functioning; some data indicate that management may improve selfreported work impairment and absenteeism. Bipolar disorder patients have been found to utilize health-care services more than do patients with depression or chronic medical conditions. Inpatient costs are the largest cost contributor; treatment to prevent recurrence has been shown to be the most effective way to reduce costs.

CONCLUSIONS

Bipolar disorder imposes a tremendous burden on patients and the health-care system, resulting in decreased HRQoL and increased medical and work impairment costs. Limited data suggest that appropriate management can improve HRQoL and functioning while reducing utilization and cost.
