  1. Overview Bipolar Disorder – Solving Clinical Challenges 1. Diagnostic Nosology Solving Clinical Challenges in – Challenges distinguishing bipolar from unipolar Bipolar Disorder 2. Pharmacologic Treatment – Challenges with therapeutic vs side effects 3. Adverse Events – Challenges with weight gain/sedation and akathisia Terence A. Ketter, MD 4. Non-Pharmacologic Treatment Professor Emeritus Department of Psychiatry and Behavioral Sciences – Challenges with access to evidence-based Rx Stanford University School of Medicine Stanford, California Ketter TA (Ed). Advances in Treatment of Bipolar Disorders . Arlington, VA: American Psychiatric Publishing, Inc.; 2015. Diagnostic Boundaries of Bipolar Disorder • Complex, variable phenomenology – Different subtypes, mood states, courses, age-dependent presentations I. Diagnostic Nosology • Crucial differential diagnosis – MDD Challenges with Accurate Diagnosis • Confounding comorbidities – Substance abuse, anxiety disorders – Disruptive behavioral (ADHD, ODD, CD), cluster B disorders • Measures to enhance diagnostic accuracy – Collateral information – DSM Screening • Mood Disorders Questionnaire – Beyond DSM • Onset age, atypical symptoms, course, treatment effects, family history ADHD = attention-deficit/hyperactivity disorder; CD = conduct disorder; MDD = major depressive disorder; ODD = oppositional defiant disorder. Ketter TA (Ed). Advances in Treatment of Bipolar Disorders . Arlington, VA: American Psychiatric Publishing, Inc.; 2015. Bipolar Disorders Symptoms Diagnostic Challenges – Question 1 are Chronic and Predominantly Depressive 146 BD-I Patients 86 BD-II Patients followed 12.8 years followed 13.4 years 1.3% 2.3% “Patients are famous for underestimating the 5.9% number and intensity of past manic or hypomanic 8.9% episodes, which can lead a clinician to inappropriately diagnosing these patients with a unipolar condition. Do you have any tips for how we can better “flush out” past manic type 31.9% 52.7% 50.3% 46.1% phenomena when we are first assessing a new Percent of Weeks patient?” Asymptomatic Depressed Elevated Cycling / mixed Dep:Elevated/Cycling/mixed = 2.2:1 Dep:Elevated/Cycling/mixed = 14:1 Judd LL, et al.

  2. Substance/Medication-Induced Diagnostic Challenges I Bipolar and Related Disorder • Patients present with depression more than mood elevation • Get collateral history from significant other (more • Prominent, persistent elevated/irritable/expansive and/or depressed mood/anhedonia sensitive rater of mood elevation) • Look for mood elevation symptoms • During/soon after substance intoxication/withdrawal or medication exposure – Immediately before or after depressions • Substance/medication capable of producing above mood – Triggered by pharmacotherapy symptoms – Mixed depressions • Not better explained by non-substance induced bipolar • In depressed patients, assess bipolar outcome risk disorder factors – eg, Symptoms persist < 1 month without – Depression onset prior to age 25; lifetime history of psychosis, substance/medication 1° relative with mania – Presence of 1 risk factor doesn’t substantively increase bipolar • Not merely delirium outcome risk (which is approximately 25% overall) • Distress, social/occupational impact – In contrast, 2 or 3 risk factors substantively increase bipolar outcome risk (to approximately 50% and 67%, respectively) American Psychiatric Association.

Antidepressant-Induced Mania More Common in Antidepressant Treatment-Emergent Bipolar II Compared to Unipolar Depression Evolution of Bipolar I Disorder from MDD Meta-Analysis from Clinical Trials 14 Unipolar Depression Bipolar II Depression Severe MDD, Single Episode, Elevation 12 11.2% Moderate (296.22) Switching to Mania (%) Antidepressant Moderate ≥ 7 days or 10 hospitalization Mild 8 None 6 ≥ 14 days 4.2% Mild 3.7% Depression 4 Antidepressant Bipolar I Disorder, Manic Moderate discontinued (296.40) 2 0.7% 0.5% 0.2% 2716 10,246 3788 125 242 48 = N Severe 0 Significance: TCA = SSRI > Placebo TCA > SSRI = Placebo Ketter TA (Ed).

Br J Psychiatry . 1994;164(4):549-550. Bipolar Mixed State Conceptualization Main Changes for Bipolar and Related Disorders in DSM-IV-TR vs DSM-5 in DSM-5 Compared to DSM-IV-TR • “with mixed features” specifier added for Manic, Hypomanic, and Major Depressive Episodes • Manic Episode with mixed features replaces Mixed Episode • Antidepressant switching – full Manic/Hypomanic Episode emerging during antidepressant treatment and persisting beyond physiological treatment effect now sufficient for Manic/Hypomanic Episode American Psychiatric Association.

  3. “Overlapping” Symptoms Not Included DSM-5 Major Depressive Episode with mixed features (AKA Mixed Depression) in DSM-5 Mixed Specifier Symptoms characteristic of both poles: • Predominant, full depressive episode and ≥ 3 most days: • Psychomotor agitation (?) ‒ Elevated / expansive mood – Inflated self-esteem / grandiosity ‒ Overtalkativeness – Racing thoughts • Distractibility ‒ Increased goal-directed activity – Impulsivity • Irritability ‒ Decreased sleep need • Mixed symptoms objectively evident, not usual behavior • Insomnia per se • Mania trumps depression • Indecisiveness • Not due to substance / medication American Psychiatric Association.
