Bipolar Affective Disorder: practical aspects and update Iouri Rybak, MD, FRCPC Assistant Professor, Dept. of Psychiatry Western University Mood and Anxiety Disorders Program Regional Mental Health Care
Objectives To appreciate diagnostic challenges and consider repercussions of misdiagnosis To implement appropriate use of clinical screeners and mood charts To utilize practical strategies to contribute to wellness as an optimal treatment outcome in patients with BD
BD comorbidity: the rule not the exception Panic Disorder 7-33% OCD 3-39% ADHD 20% Phobias 10-26% GAD 11-43%
BD comorbidity: the rule not the exception Diabetes % Alcohol abuse 56.3% Alcohol depend. 38% Drug depend 30.4% Drug abuse 48.3%
Irritability Across Disease States (Partial list) Depressive disorder ADHD CNS injuries/infections Dementia Endocrine disorders Impulse control disorders PTSD GAD Substance use Sleep disorders PMDD Personality Disorders
Dorothy ID: 44 y.o. female employed married with twin sons CC: depressed mood “lost zest for life” “Can’t concentrate” Insomnia/ hypersomnia Irritability HPI: Longsanding mild depression with 3 months worsening PPH: 8 y.o. suic. thoughts 23 y.o.-1-st depress. episode Mid 20s- alcohol abuse, shoplifting, sex promiscuity Denied somatovegetative sx 35 y.o. - postpartum depress. ED - binges and excess exercising MH: thyroid, hysterectomy
Dorothy MSE: Increased latency of speech Moderately depressed mood Sad and anxious affect Passive suicidal ideations Interested in a/depr-s optimization FHx: Mother side: depression, BD, alcohol abuse Father side: abuse family, brother –suicide.
Mania: Differential Diagnosis Mania Due to General Medical Condition Substance Induced Mood Disorder Hypomanic Episode Mood Disorder with Prominent Irritable Mood AD/HD
The Most Reasonable Diagnostic Impression Dysthymic Disorder Major Depressive Disorder Bipolar Disorder II Depression plus Alcohol Abuse in Remission
Dorothy: diagnostic challenges For BD Episode in 20s could be interpreted as manic/hypomanic Recall bias, no collateral. Related to a/depress ? FHx of bipolar disorder Postpartum depression Against BD Thyroid disorder: diagn. and treatment ( s/e)challenges ED: diagn. and treat.(weight) challenges Pt’s preference for a/depr.
Dorothy: diagnosis and follow up Dysthymic disorder with superimposed MDE Cipralex 20mg-40mg Wellbutrin SR 150mg-300mg 1-st y.: improvement with mood fluctuations’ range moderate depr. to euthymia 2-nd y.: episodes of hyperactivity, decreased need for sleep, overly talkative. Started on Epival- blood – dyscrasia - Lamotrigine.
Danger of missing BD Unopposed Antidepressant therapy: Rapid Cycling - 23 % (Ghaemi et al, 2000) Manic episode- 55% (Ghaemi et al, 2000) Mixed Episodes Psychotic Episodes Antidepressants Side Effects Non adherence to treatment Any diagnosis of MDD has to be provisional given high prevalence of switch to mania.
Danger of Overdiagnosing BD Inappropriate treatment with mood stabilizers and a/psychotics: Excessive sedation Metabolic syndrome Reproductive function Thyroid, kidney dysfunction (lithium) Liver dysf-n, blood dyscrasias ( a/convulsants)
Mixed Episode The criteria are met both for a Manic Episode and for a Major Depressive Episode for at least 1 week Severe enough to cause marked impairment in occupational functioning or in usual social activities.

Scales Screeners Mood Charts
“Accurate diagnosis has enormous implications for short- and long-term treatment planning, and it is essential to note that diagnosis is a process rather than a one thing event” APA Practice Guidelines, 2011
The Mood Disorder Questionnaire (MDQ) This questionnaire should be used as a starting point. It is not a substitute for a full medical evaluation. Bipolar disorder is a complex illness, and an accurate, thorough diagnosis can only be made through a personal evaluation by your doctor. However, a positive screen here may suggest that you might benefit from seeking such an evaluation from your doctor. Regardless of the questionnaire results, if you or someone you know has concerns about your mental health, please contact your physician or another healthcare professional.
INSTRUCTIONS: Please answer each question as best you can. YES / NO 1.Has there ever been a period of time when you were not your usual self and you felt so good or so hyper that other people thought you were not your normal self or you were so hyper that you got into trouble?... you were so irritable that you shouted at people or started fights or arguments?... you felt much more self-confident than usual?... you got much less sleep than usual and found that you didn’t really miss it?... you were more talkative or spoke much faster than usual?... thoughts raced through your head or you couldn’t slow your mind down?... you were so easily distracted by things around you that you had trouble concentrating or staying on track?... you had much more energy than usual?... you were much more active or did many more things than usual?... you were much more social or outgoing than usual, for example, you telephoned friends in the middle of the night?... you were much more interested in sex than usual?... you did things that were unusual for you or that other people might have thought were excessive, foolish or risky?... spending money got you or your family in trouble?
MDQ: scoring and interpretation Answering “Yes” to 7 or more of the events in question #1, answering “Yes” to question #2, and answering “Moderate problem” or “Serious problem” to question #3 is considered a positive screen for BD Psychiatric Patient sample: Sensitivity: 73% Specificity: 90% Community Sample: Sensitivity 28% Specificity 97% (Zimmerman,et al, 2004)
Bipolar Spectrum Diagnostic Scale BSDS is a descriptive story- subtle features of bipolar illness Addresses the concept of BD Each sentence is worth 1 point, to that total add the number below for the item selected. Add 6 points for “fits me very well”, 4 points for “ fits me fairly well”, 2 points for “fits me to some degree”. Total scoreLikelihood of BD <6Very unlikely 6-10Low probability 11-18Moderate probability 19 or higherHighly likely
Bipolar Spectrum Diagnostic Scale (BSDS) Sensitivity bipolar I : 75% Sensitivity bipolar II / NOS : 79% Overall Specificity : 85% (Ghaemi et al, 2005)
Some treatment aspects
Acute management of Bipolar Depression 1st line : Lithium, lamotrigine, quetiapine, quetiapine XR, lithium or divalproex+SSRI, olanzapine+ SSRI, lithium or divalproex + bupropion 2-nd line: Quetiapine + SSRI, adjunctive modafinil. Not recommended: Gabapentin, aripiprazole monotherapy Efficacy of pharmacotherapy in Bipolar Depression remains uncertain recent reviews and meta-analysis reinforce doubts (STEP-BD, Sidor, Mac Queen, 2011) Lamotrigine, divalproex- some benefits (Geddes et al 2009,Smith et al 2010)Lamotrigine, divalproex- some benefits (Geddes et al 2009,Smith et al 2010)
New Approaches HPI axis dysregulation- rationale for antiglucocorticoid treatment Glucocorticoid receptor antagonist- mifepristone-1 week improved: spatial memory verbal fluency depressive symptoms (MADRS) (Gallagher et al, 2009)
Ketamine in Treatment Resistant Bipolar Depression Novel mechanism of action- antagonist of NMDA receptors Targerts glutamate, major excitatory neurotransmitter in the brain 163 patients with TRD studied 25-85% response rate 24 hrs post infusion 14-70% response rate 72 hrs post infusion (Rot et al 2012)
Ketamine in Treatment Resistant Bipolar Depression Within 40 minutes, depressive symptoms significantly improved in subjects receiving ketamine versus placebo, the improvement remained significant through day 3 71% of subject responded to ketamine and 6% to placebo during the trial (Diazgranados et al 2010)
Asenapine Preclinicaly: Involves wide spectrum of receptors Improves hedonia, sleep architecture in animal model (Blier, 2012) 3 week random. mania trial – significant-day2 Comparable to olanzapine, early response predicts remission better than olanzapine. 12 weeks mixed episodes trial: manic + depress. sx improvement by 3 weeks olanzapine - didn’t differ. from placebo
Asenapine Asenapine in combination with Lithium or divalproex –superior efficacy over mood stabilizers alone Side effects: Anxiety, somnolence (dose related?) well tolerated in patients with BD-I No change in prolactine level (Citrome et al, 2009)
Difference in acute treatment of depressive, manic and mixed episodes requires accuracy in diagnostic impression.
Maintenance pharmacotherapy of BD 1-st line: Lithium, lamotrigine (depression only?), divalproex, olanzapine, quetiapine, lithium or divalproex +quetiapine, risperidone, aripiprazole, ziprazidone Asenapine (Sycrest) In 40 weeks trial asenapine >olanzapine (Grunze, 2012) Not recommended: Adjunctive flupenhtixol, monotherapy with gabapentin, topiramate and a/depressants

MAPS program Combined Psychoeducation, CBT and Social Rhythms approaches including: M- monitoring mood and activities A- assessing prodromes P- preventing relapse S- SMART goal setting (specific-measurable-actionable-realistic-time bound)
Circadian rhythm (CR) instability Multiple competing inputs for CR advance/delay timing of work/chores meals social contacts In vulnerable individuals, changes in social time cues could lead to disruption in CR and ultimately to relapse
Sleep disturbance in BD The most evident “symptom” of CR disruption is the disturbance of sleep Managing sleep is fundamental priority in BD because: Sleep deprivation may trigger mania Persistent sleep disturbance is common Altered sleep may be a predictor of relapse Alteration in sleep-wake cycle may have harmful effects on general health, incl. weight gain and insulin resistance
Interpersonal and Social Rhythm Therapy (IPSRT) IPSRT has been shown to: speed time to remission of bipolar depression prolong remission of an affective episode reduce suicide attempts improve occupational functioning (Mildowitz et al, 2007)
Bright Light Therapy (LT) for CR disturbance LT open trial in mood and cognitive sx (ADHD) LT significantly improved mood, core ADHD symptoms, and objective measures of attention LT may corect circadian phase disturbance contributing to both subjective and objective dysfunction in adult ADHD independently of mood improvement ( Rybak et al, 2006)
CBT for BD Education: initial stage, engagement, most of pts know very little Behavioral interventions: taking actions to control sx - monitoring avoid exacerbating stimuli Cognitive component: twisted thinking Chain analysis
CBT for BD Examples of Socratic questions re: the presence of mania: Do you think you are manic? Have you ever felt this way before? If not, what do you think is happening to you? If not, why do other people seem to think you are manic? How is mania different from how you feel now? Is it possible that you are getting manic and just don’t want to see it?
CBT for BD Examples of Socratic questions re: the presence of mania: How do you explain your change in mood. How could you tell if this was mania or something else? What would have to happen to convince you that this is mania Interactive CBT program: https://moodgym.anu.edu.au
