3
Objectives Be able to make a differential diagnosis for PTSD and Bipolar Disorder Be familiar with common co-occurring illnesses with bipolar disorder, including anxiety disorders Be familiar with most recent VA guidelines for management and treatment of bipolar disorder
4
The Extraordinary Toll of Medical Illness in Bipolar Disorder People with serious mental illness die 25 years earlier than the general population Much attributed to smoking, obesity, substance abuse, and inadequate access to medical care WHO lists Bipolar Disorder as 6 th worldwide all cause morbidity and mortality Colton C & Manderscheid R. Prev Chronic Dis 2006;3(2):1-10.
5
Costs Associated with BD in the VA Total VA direct costs for this illness are over $900,000,000 per year - 2007 Blow F et al. Care in the VHA for Veterans with Psychosis: FY2007
6
Bipolar Disorder Also known as manic depression, a mental illness that causes a person’s moods to be labile and sometimes swing from extremely happy and energized (mania) to extremely sad (depression) Chronic illness; can be life-threatening Most often diagnosed in adolescence or early adulthood
7
Diverse Episodes, Frequencies, Patterns A Mood Chart Is Worth 1000 Words Hypomania Severe Moderate Mild Moderate Severe Mania* Depression Minor depression Euthymia Hypomania * Euphoric or mixed mania Mania Depression
8
Secondary Mania Post-TBI Bipolar Symptoms NosologySleeplessness, impaired judgment, grandiosity, irritability, pressured speech in 80%--100% of cases; hyperactivity in 65% and hypersexuality in 50% Epidemiology Incidence 9.1% Prevalence 0.83—22.2% Risk FactorsProlonged post injury amnesia Seizures Multifocal lesions Frontal lesions Orbitofrontal lesions Temporal lesions Non-dominant hemispheric lesions Kim et al. J Neuropsychiatry Clin Neurosci 2007.
9
Underdiagnosis of Bipolar Disorder - 600 patients with bipolar disorder; retrospective diagnostic history. - 69% of patients previously misdiagnosed Most common alternative primary diagnoses: Depression60% Anxiety Disorder26% Schizophrenia18% Borderline/Antisocial PD 17% - Patients were misdiagnosed 3.5 times on average - 4 physicians were consulted prior to diagnosis Hirschfield et al. J Clin Psychiatry 2003;64:161-174.
10
Overdiagnosis of Bipolar Disorder --MIDAS Project, Rhode Island (n=700) – 145 patients reported past diagnosis of Bipolar Disorder – 82 of 145 were NOT diagnosed Bipolar when given structured interviews Zimmerman, et al., 2008; Zimmerman, et al., 2010.
11
DSM 5 One of the goals on the Mood Disorder committee is to decrease false positives Proposed changes for mood disorders to emphasize: episodic nature of symptoms; importance of activity/energy change in hypo/mania; and evaluating for clusters of symptoms
12
Comorbidity and Symptom Sharing MANIADEPRESSIONANXIETY Elated Mood Irritability Increased EnergyAgitation Restlessness/Agita tion DistractibilityPoor Concentration Difficulty in Concentration Flight of Ideas Grandiosity Poor Judgment Reduced SleepInsomnia
13
Differential Diagnosis: PTSD and BD Prominent PTSD mood may be chronic and debilitating anxiety versus episodic symptoms of depression and hypo/mania PTSD mood can also wax and wane depending on acuteness and individual triggers Hypomania or mania may be a mixed picture and not only euphoric, e.g. “energized depression”
14
cont’d Careful history taking regarding insomnia and energy levels is key Bipolar hypo/mania will have less sleep but more energy Always evaluate for CLUSTERS of symptoms to make the differential or diagnose co-occurring conditions
15
cont’d Increased arousal associated with PTSD can mimic hypo/mania; numbing and avoidance can appear as depression In many cases, symptoms of anxiety may co-exist with those of bipolar disorder Extensive co-occurrence of anxiety disorders, including PTSD, and bipolar disorder
16
Psychiatric Co-Occurrence in Bipolar Disorder Common psychiatric co-occurrences –Substance abuse –Anxiety disorders –Eating disorders Co-occurrence is a marker for bipolarity
17
Co-occurring disorders is Important Consideration for Veterans In 2002-2008, about 1/3 vets with MH disorders had 2 co-occurring & 1/3 had 3 or more (Seal, 2009). A 2005 report showed that 38% of vets with BD have a co-occurring anxiety disorder (Kilbourne, 2005). BD and PTSD are among the highest rates of co-occurring illnesses. Kilbourne et al. Bipolar Disord 2005;7:89-97; Seal et al., Am J Public Health 2009;99:1651-1658.
18
Prevalence of Psychiatric Co-Occurrence: STEP-BD 1000 Simon et al. J Clin Psychopharmacol 2004. Number of Co-occurring Disorders: 1 – 72%; 2 – 20%; 3 – 15%; 4 – 17%
19
Comorbid anxiety associated with: earlier age of illness onset; higher rates of mixed states, depressive symptoms, suicidality, substance use, and psychosis; LONGER TIME TO REMISSION; more severe medication side effects; lower quality of life; POOR RESPONSE to treatment. Freeman et al., 2002; McElroy et al., 2001; Frank et al., 2002, Feske et al., 2000, Kauer-Sant’Anna et al, 2007.
20
2010, > 40% of veterans seen in MH division diagnosed with an anxiety disorder: – PTSD39% – anxiety state16% 2010, there were 7,089 (39%) active veterans with PTSD as primary or secondary MH diagnosis – A total of 49,235 encounters Veterans 2010 with PTSD, 9% or 638 also have a BD diagnosis.

22
Increased Risk of Suicide Patients with BD + anxiety are at higher risk of suicide. Where does that leave veterans with BD + anxiety? MacKinnon et al. Bipolar Disord 2005; Kilbane et al. J Affect Disord 2009; Kaplan et al. J Epidemiol Community Health 2007; McCarthy et al. Am J Epidemiol 2009.
23
Veterans and Suicide Veterans are at a higher risk for suicide than the general population. Recent study - Veterans with BD among the highest risk of committing suicide ; those with anxiety disorders (including PTSD) in top six groups at risk for suicide. Sample size - 3,291,891 Veterans Kaplan et al. J Epidemiol Community Health 2007;61(8):751; McCarthy et al. Am J Epidemiol 2009;169(8):1033-8; Ilgen et al. Arch Gen Psychiatry 2010;67(11):1152-1158.

Guidelines: Aligning the Arrows
30
What are treatment guidelines? Treatment options based on research evidence, clinical experience, and/or expert opinion. Can include pharmacological, psychosocial, or other treatment approaches. Published guidelines vary in their organization, commitment to evidence-base, and flexibility. Guidelines must be updated regularly to reflect changes in available evidence.
31
Clinical elements relatively unique to bipolar disorder Majority of patients on 3-5 medications. Combinations often necessary to achieve mood stabilization. Drug holidays never recommended. Other medical and co-occurring illness must be considered throughout period of treatment

Pharmacology for Patients experiencing Mania, Hypomania or Mixed Episodes Stop manic-inducing medications; Use medication proven to effectively treat manic and mixed manic symptoms; Consider using the agent(s) that have been effective in treating prior episodes;
40
Cont’d Consider other psychiatric and medical conditions and try to avoid exacerbating them; If diabetes or obesity are present, consider the risk and benefit of utilizing medications that are associated with weight gain.
41
If mania/mixed symptoms are severe, with or without psychosis: Use a combination of an antipsychotic and either Li or DVP. If severe mania - olanzapine, quetiapine, aripiprazole, or risperidone [B] and ziprasidone [I] If severe mixed - aripiprazole, olanzapine, risperidone, or haloperidol [B] and quetiapine or ziprasidone [I]
42
If monotherapy is insufficient… ADJUST medications if there is no response within 2 – 4 weeks on an adequate dose; Consider SWITCHING to another monotherapy [I]; Consider COMBINATION therapy (see guidelines for choices for severe mania and/or mixed symptoms);
43
Cont’d Consider Clozapine, particularly if it has been successful in the past or if other antipsychotics have failed [I]; Electroconvulsive therapy (ECT) may be considered [C]; Risks and benefits of specific long-term pharmacotherapy should be discussed prior to starting medication and throughout all treatment [A]

45
Bipolar Depression Patients should be treated with medications with demonstrated efficacy in depressive episodes - minimizing the risk of switch; Consider agent(s) effective in treating prior episodes; Risk for mood destabilization to mania should be monitored closely for emergent symptoms [I]; For patients with psychotic features, an antipsychotic should be started [I];
46
cont’d Consider adding an evidence based psychotherapeutic intervention to improve adherence and patient outcome [B]; Consider other psychiatric and medical conditions and try to avoid exacerbating them; If diabetes or obesity are present, consider the risk and benefit of utilizing medications that are less associated with weight gain.

55
Maintenance Therapy A structured approach is recommended [A]; Patients who have had an acute manic episode should be treated for at least 6 months after the initial episode is controlled and encouraged to continue on life-long prophylactic treatment [A]; Risks and benefits of long term pharmacotherapy should be discussed prior to starting medication and should be continued throughout treatment [C];
56
Suppes et al. Arch Gen Psychiatry 1991. In early 1990s, there were basic questions to answer in treatment of BD, for example, should patients be prescribed drugs continuously?
57
Cont’d Patients who have had >1 manic episode, or 1 manic and depressive episode, or >2 depressive episodes, should be encouraged to continue on life-long prophylactic treatment, as the benefits outweigh the risks [A]; If medications are to be discontinued, they should be slowly and GRADUALLY TAPERED over at least a 2 to 4 week period, unless medically contraindicated, to prevent a “REBOUND” episode of bipolar disorder and/or increase the risk of suicide [B].
58
Patients in remission should be seen every 1 to 3 months with ongoing assessment of recent symptoms [I]; All patients on medication should be monitored for potential adverse effects [B]; Monitor serum concentrations (as appropriate) and other appropriate blood work every 3 to 6 months to maintain efficacy and avoid toxicity [A/B]; For those on APs, monitor weight, waist circumference, blood pressure, BMI, plasma glucose and fasting lipids [C]. Adherence to medication therapy should be routinely evaluated at each visit [A]; Assess any changes in patient’s family and community support [C].
59
Adjunctive Psychoeducation Psychoeducation should emphasize [B]: – The importance of active involvement in treatment – The nature and course of their bipolar illness – The potential benefit and adverse effects of treatment options – The recognition of early signs of relapse – Behavioral interventions that can lessen the likelihood of relapse including careful attention to sleep regulation and avoidance of substance misuse.
60
Cont’d With the patient’s permission, family members or significant other should be involved in the psychoeducation process [C]; A structured group format in providing psychoeducation and care management for patients with clinically significant mood symptoms should be considered [A].
61
Adjunctive Psychotherapies CBT for those who have achieved remission from an acute manic episode and who have had <12 previous acute episodes [A]; IPSRT for those who have achieved remission from an acute manic episode and are maintained on prophylactic medication [B];
62
Cont’d Structured Family therapy can be considered for couples and families who are coping with BD [C]; Patients may benefit from chronic care model-based interventions [B], especially when more symptomatic or recently hospitalized [A].
63
Applying this Guideline to Patients with BD and PTSD
64
RCTs of BD w/co-occurring Anxiety CitationDurationSubgroupOutcome Sheehan et al., 2009 8-weekPanic disorder or GAD (n=111) Risperidone = placebo on CGI- Anxiety Severity Tohen et al., 2007 8-weekCo-occurring anxiety symptoms (n=833) OLZ and OFC > PBO for response and remission rates Hirschfeld et al., 2006b 8-weeksCo-occurring anxiety symptoms (n=542) QTP > PBO for reduction in HAM-A Maina et al., 2008 12 weeksComorbid anxiety disorder (n=47) OLZ or LTG + Li; both effective in reducing HAM-A
