  • The “bible” with which the diagnosis of BPD is currently made is the APA’s DSM, currently in it’s fourth edition with a text revision update. Diagnosis of BPD according to the DSM is complex: Four subtypes: 1. Bipolar Disorder I 2. Bipolar Disorder II 3. Cyclothymia 4. Bipolar Disorder Not Otherwise Specified Five types of episodes: 1. Manic 2. Hypomanic 3. Mixed 4. Depressed 5. Unspecified Four severity levels: 1. Mild 2. Moderate 3. Severe without psychosis 4. Severe with psychosis Three course specifiers 1. With or without inter-episode recovery 2. Seasonal pattern 3. Rapid cycling
  • This study of patients with bipolar disorder who were members of the US National Depressive and Manic Depressive Association found that 60% reported significant problems related to symptoms of bipolar disorder before the age of 20 years. References Hirschfeld RM, et al. J Clin Psychiatry 2003;64:161-174.
  • Patients with bipolar disorder have high rates of psychiatric comorbidity. The most common psychiatric comorbidities are anxiety disorders, substance abuse and dependence, and conduct disorders. The presence of psychiatric comorbidity complicates the diagnosis and treatment of bipolar disorder and is often associated with poor prognosis. References Kessler RC, et al. Psychol Med 1997;27:1079-1089.
  • An analysis of the impact of bipolar I or II disorder compared with unipolar depression in the workplace reveals that the impact of bipolar disorder is substantially worse than that of unipolar disorder (US study). Approximately 50 days of work are lost annually per worker with bipolar disorder compared with 32 days per worker with major depression. References Kessler RC, et al. Arch Gen Psychiatry 2005;62:590-592: National Comorbidity Survey Replication (NCS-R).
  • Bipolar disease state slide kit _ 10 January 2008 [FINAL VERSION] Impact of bipolar disorder on patients’ lives It is estimated that an adult who has developed bipolar disorder loses 12 years of a healthy life, 14 years of working life and that their life expectancy is reduced by 9 years. Bipolar disorder also has an effect on employment and marriage as shown in a study by Coryell et al, who examined the impact bipolar disorder had on patients’ lives. Patients with bipolar disorder (n=148) were assessed when they first sought treatment and then again after 5 years follow-up. Results showed that employment problems and divorce/separation were twice as common in patients with bipolar disorder. References Coryell W et al. The enduring psychosocial consequences of mania and depression. Am J Psychiatry 1993; 150: 720-727. Scott J. Psychotherapy for bipolar disorder. Br J Psychiatry 1995; 167: 581-588.
  • This slides summarises standardised mortality ratios (observed deaths/expected deaths) among untreated and treated hospitalised patients with bipolar disorder followed prospectively in Switzerland by Angst. Not only was suicide more common in bipolar disorder, but many general medical causes of death were also elevated. Being on any form of treatment consistently reduced the mortality rates. Overall mortality was significantly lower in treated than in untreated patients. Mortality was also significantly lower among treated patients for cancer, vascular diseases, suicide and other causes except accident or intoxication. In particular, treatment was associated with marked reductions in rates of suicide. This highlights the importance of accurate diagnosis of bipolar disorder so that patients receive appropriate drug therapy. References Angst F, et al. J Affect Disord 2002;68:167-181.
  • The Mood Disorder Questionnaire (MDQ), a validated screening instrument for bipolar I and II disorders, was sent to a sample of 127,800 people selected to represent the US adult population by demographic variables. 85,358 subjects (66.8% response rate) that were 18 years of age or above returned the survey and had usable data. Of the non-respondents, 3404 subjects matched demographically to the 2000 US Census data completed a telephone interview to estimate non-response bias. Among persons who elected to complete the MDQ, only 20% with scores indicative of bipolar disorder had ever received any diagnosis for bipolar disorder. References Hirschfeld RM, et al. J Clin Psychiatry 2003;64:53-59.
  • As you can see from the 2000 National Depressive and Manic Depressive Association’s Bipolar Survey, correct diagnosis has been a tough challenge, historically. Just three years ago, 69 percent of patients in the survey had been misdiagnosed as having unipolar depression, when in fact they were suffering with bipolar disorder. And 35 percent of them waited at least 10 years for the correct diagnosis to be made.
  • This study of patients with bipolar disorder who were members of the US National Depressive and Manic Depressive Association found that for the patients who had ever received any other psychiatric diagnosis, the diagnoses were widely varying, but with depression and anxiety clearly at the top. References Hirschfeld RM, et al. J Clin Psychiatry 2003;64:161-174.
  • The diagnosis of bipolar depression may be particularly difficult to make in the absence of spontaneous mania or hypomania. A series of empirical studies have suggested the existence of several predictors of bipolarity in such cases. The latter are related to personal and family history, temperament, characteristics of the depressive episode and response to antidepressants. The main identifying features of bipolar depression suggested by these studies are presented on this slide as well as on the following one. References Nassir Ghaemi S et al. Can J Psychiatry 2002;47:125–134. Kaye NS. J Am Board Fam Pract 2005;18:271–281.

  • In the National Institute of Mental Health (NIMH) Systematic Treatment Enhancement Program for Bipolar Disorder (NIMH STEP BD), among 1,360 US patients who entered experiencing a depressive episode, 69% had at least one manic symptom. The most frequent manic symptoms did not include elation or grandiosity. Rather, distractibility, racing thoughts, rapid speech, increased activity were the most prevalent, with the latter four associated with at least four manic symptoms in the majority of patients. References Goldberg JF et al. Am J Psychiatry 2009; 166:173–181.
  • The MDQ can be used to identify patients most likely to have bipolar disorder. The MDQ is a screening instrument and not a diagnostic tool. It has been validated in a psychiatric outpatient setting and in the general population. It contains 13 questions, concerning mood, self–confidence, energy, sociability, interest in sex, and other behaviours, plus two items assessing symptom co–occurrence and the severity of functional impairment caused. References Hirschfeld RM et al. Am J Psychiatry 2000;157:1873–1875. Available at http://www.dbsalliance.org/pdfs/MDQ.pdf
  • The HCL-32 is a 32-item questionnaire that may help identify the hypomanic component of depressive episodes and increase the detection rate of both bipolar disorder type II and minor bipolar disorders (bipolar spectrum disorders). Using this brief questionnaire helps to identify patients most in need of more detailed psychiatric diagnosis. The HCL–32 is currently validated in several countries. References Angst J et al. J Affect Disord 2005;88:217–233.
  • The BSDS was originally designed to detect the milder portions of the bipolar spectrum in outpatients. It is composed of two parts: The first part is a paragraph containing 19 positively valenced sentences describing many of the symptoms of bipolar disorder. Each sentence is followed by an underlined space for subjects to place a checkmark if they feel that it applies to them. Each checkmark is worth one point The second part of the BSDS is one simple, multiple–choice question, asking subjects to rate how well the story describes them overall: This story fits me very well, or almost perfectly (6 points) This story fits me fairly well (4 points) This story fits me to some degree, but not in most respects (2 points) This story doesn't really describe me at all (0 point) The total score on the BSDS can range from 0 to 25 References Nassir Ghaemi S et al. J Affect Disord 2005;84:273–277. Available at http://www.psycheducation.org/depression/BSDS.htm

  • Bipolar disease state slide kit _ 10 January 2008 [FINAL VERSION] Treatment aims in bipolar disorder Patients with bipolar disorder require a comprehensive and long-term programme of medical care to help them overcome their symptoms and functional impairment associated with this highly recurrent disorder. The main goal of treatment is to ensure mood stabilisation in patients with bipolar disorder. This can be achieved by controlling the acute symptoms of bipolar disorder and in the long term preventing relapse. It is also important to ensure that patients adhere to treatment and that any comorbid conditions are managed effectively. Reference Vieta E. The package of care for patients with bipolar depression. J Clin Psychiatry 2005; 66 (Suppl 5): 34-39.
  • Electroconvulsive therapy (ECT) is considered a mood-stabilizing treatment. It tends to be used for patients who are suicidal or severely ill and cannot wait for medications to work, or have a history of nonresponse to treatments. Lithium has been the main treatment for acute mania for over 40 years. Lithium appears to be effective for individuals with euphoric mania, but is less effective in mixed manic episodes and in rapid-cycling bipolar disorder. First-generation antipsychotic treatments have been prescribed to combat the psychotic symptoms sometimes associated with manic episodes of bipolar I disorder. Antipsychotics are also used to treat symptoms of anxiety, insomnia, and agitation often associated with manic episodes, even when no psychosis occurs. Antipsychotics are used both as monotherapy and as adjuncts to mood stabilizers for the initial treatment of acute mania. However, intolerable side effects associated with conventional antipsychotics, such as EPS and tardive dyskinesia (TD), can increase patient health burden and have a negative impact on compliance. Valproic acid and its salts (divalproex sodium and sodium valproate), originally developed as an anticonvulsant to treat seizures, have been used to treat bipolar disorder for a number of years. While data support its efficacy in treating euphoric and mixed manic episodes, the data to support efficacy in prophylaxis are considerably weaker. Preliminary research suggests that several other anticonvulsants (eg, lamotrigine, gabapentin, and topiramate) may also possess mood- stabilizing properties. Second-generation antipsychotics have a greatly improved side-effect profile over conventional antipsychotics in terms of EPS and TD liability. Currently, olanzapine is the only atypical agent approved for use in acute mania. Although atypical agents show improvements over conventional agents, concerns remain regarding the emergence of drug-specific side effects such as excessive weight gain, diabetes, lipid abnormalities, QTc prolongation, and somnolence. Aripiprazole is a novel antipsychotic with a unique mechanism of action. This new agent shows promise as a treatment with efficacy against acute mania and an improved safety and tolerability profile. 1. Nemeroff CB.
