Introduction  

Bipolar spectrum disorders are a major public health problem, with estimates of lifetime prevalence in the general population of the United States at 3.9 percent,with a range from 1.5 to 6.0 percent.Bipolar disorder is also associated with significant mortality risk, with approximately 25 percent of patients attempting suicide and 11 percent of patients completing. Furthermore, inadequate treatment and service structure causes high rates of jailing for bipolar patients.Bipolar depression is still undertreated, too, with patients suffering such symptoms 31.9 percent of the time over nearly 13 years.

More pharmacologic options are now available, and psychoeducation, self-help, and psychotherapy (individual, couple, and family) interventions are frequently utilized.The Depression and Bipolar Support Alliance has taken a leading role in educating patients, their families, medical professionals, mental health professionals, and the public at large about manic-depressive illness. The National Alliance of the Mentally Ill (NAMI) has also sought information by surveying family members about utilization and value of mental health services.

Epidemiology

Bipolar I disorder starts on average at 18 years and bipolar II disorder at 22 years.A community study using the Mood Disorder Questionnaire (MDQ) revealed a prevalence of 3.7 percent.The National Comorbidity Study showed onset typically between 18 and 44, with higher rates between 18 and 34 than 35 and 54.1In a survey of members of the DBSA, more than half of the patients did not seek care for five years and the correct diagnosis was not made until an average of eight years after they first sought treatment.

Cognitive processing is often impaired in bipolar patients, even in euthymic patients.Executive function, visulospatial, memory, verbal fluency, and attentional deficits have been noted. This may be a primary feature of bipolar disorder, secondary to other dysregulation (e.g., insomnia) or secondary to comorbid conditions (e.g., substance use). Cognitive assessment is underutilized in assessing medication side effects, the return to the outpatient sector from inpatient, and employing vocational rehabilitation in preparation for work.

Assessment

The evaluation of a bipolar patient involves a number of important clinical and psychosocial issues. The primary tool is the neuropsychiatric assessment with the history and physical examination. Brief histories (less than 30 minutes) may be a liability, due to the complexity of the mood course in patients not already diagnosed. Collateral information is required in most cases from family, friends, or prior places of treatment. A delineation of episodic versus chronic symptoms is helpful, except with patients with cycling of mood day-to-day, in a mixed episode, or otherwise very unstable course. Screening instruments can be used for manic episodes (e.g. Mood Disorder Questionnaire [MDQ]), though they may have more utility in primary care settings. The MDQ has 13 yes/no items, and seven positive answers call for a full clinical evaluation.

Psychosocial treatments for bipolar disorder. Psychotherapeutic treatments, provided individually or through groups and families, are beneficial to nearly all patients with bipolar disorder and provide the context in which psychiatric management and pharmacotherapy work best.Most patients struggle with psychosocial issues Bipolar inpatients were surveyed about their informational needs in one study, and they requested information about bipolar disorder, how to obtain support, how to manage symptoms (e.g., suicidal ideation, anger), and how to improve interpersonal skills. Economic, interpersonal, and vocational problems may occur for years, even when patients do not suffer recurrence of illness leading to hospitalization.

A summary of psychotherapeutic treatments reveals better outcomes and improved adherence to treatment. Cognitive-behavioral, family-focused psychoeducation (also known as behavioral family management), inpatient family, and group psychotherapy have been studied. Easy access to a primary nurse provider increases outpatient utilization without increasing costs.These interventions bridge the gap between ideal controlled trials and everyday practice, in which patients and families benefit from the increased structure of the interventions.

Mood stabilizers for mania. Mood stabilizers are the mainstay of treatment for bipolar disorder, regardless of whether the patient's presentation is manic or depressed. These medications generally require 1 to 4 weeks at therapeutic doses before their full effects are seen. Approximately 50 to 60 percent of patients will respond sufficiently to a single mood stabilizer,while others may require combined pharmacotherapy.They are commonly used in conjunction with benzodiazepines (anxiety, agitation) and other medications.

Methods

A nationwide non-interventional study using psychiatrists’ and patients’ surveys.

Results

839 patients with bipolar or schizoaffective disorder bipolar type were included. Concordance with the guideline was highest for participation of a psychiatrist in the treatment (98%) and for maintenance pharmacotherapy (96%), but lower for supportive treatment (73.5%), use of an emergency plan (70.6%), psychotherapy (52.2%), group psychoeducation (47.2%), and mood monitoring (47%). Presence of a written treatment plan, a more specialized treatment setting, more years of education, and diagnosis of bipolar I disorder versus bipolar II, bipolar NOS, or schizoaffective disorder were significantly associated with better concordance.

Socio-demographic and illness characteristics

Five hundred and fifty-five respondents (66.2%) were women. The average age was 49.5 years (s.d. 11.2). Five hundred and one out of 833 (60.1%) respondents were married or living together. The mean years of education (n = 837) was 16.1 years (s.d. 4.3). Diagnoses were BD I (n = 551; 65.7%), BD II (n = 211; 25.1%), BD NOS (n = 32; 3.8%), and SZA (n = 45; 5.4%). At least one comorbid psychiatric diagnosis was present in 238 respondents (28.4%). The mean duration of illness (n = 712) was 23.8 years (s.d. 12.3). The average age at onset for (hypo) manic symptoms was 30.1 years (s.d. 11.8), and for depressive symptoms 26.1 years (s.d. 11.7). Only nine respondents (1.1%) experienced one single manic episode, 28 (3.3%) had two mood episodes, all other 718 respondents (85.6%) had three or more mood episodes. Data on total lifetime number of mood episodes were inconclusive or missing in 84 respondents (10%). Hospital admission because of a mood episode was reported by 532 (63.4%) respondents. Data on admission were missing in 65 respondents (7.7%). Of the respondents, 283 (33.7%) had a first degree relative with bipolar disorder.

Concordance with treatment guideline

Concordance with the guideline for each treatment modality was as follows: participation of a psychiatrist in 757 of 773 respondents (97.9%), maintenance pharmacotherapy in 754 of 786 (95.9%), supportive treatment in 560 of 762 (73.5%), use of an emergency plan in 556 of 787 (70.6%), psychotherapy in 399 of 765 (52.2%), group psychoeducation in 371 of 786 (47.2%), and mood monitoring in 369 of 785 respondents (47%).

In a multiple regression analysis age, absence of psychiatric comorbidity, duration of illness, and whether or not it was asked to involve significant others in the treatment, did not contribute significantly to the model, although the latter almost reached significance. All other factors were significant. The model explained almost 10% of variance in concordance scores.

Conclusion

The lifetime management of patients with bipolar disorder is challenging, because of the dynamic, chronic, and fluctuating nature of this disease. The healthcare costs for patients and their caregivers are enormous from psychosocial and economic perspectives. It is incumbent on healthcare professionals to reduce the burden of bipolar disorder. Pharmacologic treatment is the mainstay of treatment for patients with bipolar disorder. Although mood stabilizers have been the cornerstone of therapy, the availability of atypical antipsychotics has significantly modified the approach to care. Individual atypical antipsychotic medications have been shown to be effective for acute mania/hypomania, for acute depression, and for maintenance treatment (of mania and depression), and have been incorporated into many treatment guidelines. The diligent selection of a specific agent that takes into account its efficacy in the various phases of bipolar disorder, along with its safety profile, can help to ameliorate the impact of this devastating condition.
