4 Bipolar Unipolar Distinction Leonhard 1957 Angst & Perris 1966 Validated by family history study 7 Bipolar Disorder: Natural History Onset late adolescence and early adult (peak 15 24) secondary mania more common > 60 yrs Course recurring lifelong disorder decreasing inter episode intervals 8 Longitudinal Course of Bipolar Disorder Elevated Mood Mania Threshold Severity Subsyndromal Period Major Depression Threshold Depressed Mood Acute Bipolar Mania 9 3

5 Subtypes of Bipolar Disorder Bipolar I Disorder Bipolar II Disorder Cyclothymia Substance/Medication Induced Bipolar Disorder Bipolar Disorder Due to Another Medical Condition Other Specified Bipolar Disorder 10 Epidemiology of Bipolar I Disorder ECA Study 1981 Lifetime prevalence = 1.2% 3.1 million in US National Comorbidity Study 1994 Lifetime prevalence = 1.6% 4.2 million in US Gender distribution M = F 11 Epidemiology of Bipolar Disorders Bipolar II Disorder Lifetime prevalence = 3% Females > Males Bipolar Spectrum Disorders Lifetime prevalence = 4 5% PC or MH clinics prevalence = 20 50% 12 4

6 Genetic Factors Lifetime risk of Bipolar Disorder in first degree relatives 40 70% in monozygotic twin 5 10 % in all other relatives 13 Those? Oh, just a few souvenirs from my bipolar-disorder days 14 Bipolar Disorder: Morbidity Illness recurrent in 90% patients Depressive phase is 3 4 times more frequent than the Manic phase Functional recovery often lags behind symptomatic and syndromal recovery Recurrent severe episodes may result in persistent deterioration in functioning Increased number of episodes may affect subsequent treatment response and outcome Rapid cycling and mixed states more common in Females 15 5

7 Bipolar Disorder: Comorbidity Medical burden influences the psychiatric outcomes in patients with BP Disorder Severity of medical comorbidities and depression are closely linked in BP I patients BP I patients with more severe medical comorbidities while depressed have worse prognoses Medical comorbibities may disrupt sleep and other circadian rhythms causing mood destabilization Childbirth may trigger a hypomanic episode in 10 20% females 1/3 individuals with Bipolar Disorder report lifetime history of suicide attempts 16 Diagnostic criteria for a Manic Episode A. Abnormally and persistently elevated, expansive, or irritable mood increased goal directed activity or energy lasting at least 1 week DSM-5 17 Diagnostic criteria for a Hypomanic Episode A. Abnormally and persistently elevated, expansive, or irritable mood increased goal directed activity or energy lasting at least 4 days DSM

8 Diagnostic criteria for a Manic Episode B. 3 of the following; present to a significant degree and represent a noticeable change from usual behavior: 1. inflated self esteem or grandiosity 2. decreased need for sleep 3. more talkative than usual or pressure to keep talking 4. flight of ideas or subjective experience of racing thoughts 5. Distractibility (unable to censor immaterial external stimuli) 6. increase in goal directed activity (socially, at work or school, or sexually) or psychomotor agitation 7. excessive involvement in activities with high potential for painful consequences (engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments) DSM-5 19 Is this a real proposal, or are you off your medication? 20 Diagnostic criteria for a Hypomanic Episode B. 3 of the following; present to a significant degree and represent a noticeable change from usual behavior 1. inflated self esteem or grandiosity 2. decreased need for sleep 3. more talkative than usual or pressure to keep talking 4. flight of ideas or subjective experience of racing thoughts 5. Distractibility (unable to censor immaterial external stimuli) 6. increase in goal directed activity (socially, at work or school, or sexually) or psychomotor agitation 7. excessive involvement in activities with high potential for painful consequences (engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments) DSM

9 Diagnostic criteria for a Manic Episode C. Marked impairment in social or occupational functioning or necessitate hospitalization to prevent harm to self or others, or there are psychotic features. DSM-5 22 Diagnostic criteria for a Manic Episode D. Episode is not attributable to the physiological effects of a substance or to another medical condition DSM-5 23 Diagnostic criteria for a Hypomanic Episode C. Episode is associated with an unequivocal change in functioning that is uncharacteristic when not symptomatic D. Disturbance in mood and change in functioning are observable by others DSM

10 Diagnostic criteria for a Hypomanic Episode E. Episode not severe enough to cause marked impairment in social or occupational functioning or to necessitate hospitalization (psychotic features = manic episode) DSM-5 25 Diagnostic criteria for a Hypomanic Episode F. Episode is not attributable to the physiological effects of a substance (e.g. drug of abuse, medication, other treatment) DSM-5 26 Secondary Mania Medications, drugs of abuse: corticosteroids phencyclidine levodopa Endocrine: thyrotoxocosis Cushing's disease Metabolic: postoperative delirium dialysis CNS pathology: infection, neoplasm, infarct, trauma AIDS multiple sclerosis 27 9

11 Stages of Mania Euphoria (lability, irritability) Increased psychomotor activity, tangential thinking Expansive, grandiose, overconfident Increased sexuality, spending money, telephone use, letter writing Not out of control Carlson & Goodwin Stages of Mania Increasing dysphoria (overt anger, explosive, assaultive) Psychomotor acceleration, pressured speech Flight of ideas, cognitive disorganization Paranoid / grandiose delusions Carlson & Goodwin Stages of Mania Marked dysphoria (desperate, hopeless) Frenzied psychomotor activity (bizarre) Incoherent, loose associations Bizarre, idiosynchratic delusions Hallucinations Disorientation Carlson & Goodwin

12 Longitudinal Course of Bipolar Disorder Elevated Mood Mania Threshold Severity Subsyndromal Period Major Depression Threshold Depressed Mood Acute Bipolar Mania 31 Problems in Diagnosing Bipolar Disorder 7 of 10 patients are initially misdiagnosed 3.5 misdiagnoses and 4 consultations, on average, before receiving an accurate diagnosis 1/3 will seek help for ten years before being accurately diagnosed NDMDA Constituent Survey Differential Diagnosis of Bipolar Disorder Nonpsychotic: Major depression Generalized anxiety, panic, or PTSD Secondary mania Personality disorder ADHD Rating scales? 33 11

20 Treatment of Mania: Summary Although divalproex has replaced lithium as the first line standard, lithium s utility should not be underestimated Inconsistent evidence for novel anticonvulsants Strong evidence for all second generation antipsychotics Attention to adherence, lifestyle, self monitoring, and psychotherapeutic needs is essential 55 Tiered Treatment of Bipolar Depression Tier 1: SGA olanzapine +fluoxetine quetiapine monotherapy lurazidone monotherapy and adjunctive Tier 2: Mood Stabilizers lithium lamotrigine 56 Tiered Treatment of Bipolar Depression Tier 3: other clinical options adjunctive antidepressants adjunctive modafinil other mood stabilizers: divalproex, carbamazepine other SGAs electroconvulsive Therapy adjunctive psychotherapy From Ketter TA,
