8 Mania: Differential Diagnosis Mania Due to General Medical Condition Substance Induced Mood Disorder Hypomanic Episode Mood Disorder with Prominent Irritable Mood AD/HD
9 The Most Reasonable Diagnostic Impression Dysthymic Disorder Major Depressive Disorder Bipolar Disorder II Depression plus Alcohol Abuse in Remission
10 Dorothy: diagnostic challenges For BDEpisode in 20s could be interpreted as manic/hypomanicRecall bias, no collateral.Related to a/depress ?FHx of bipolar disorderPostpartum depressionAgainst BD Thyroid disorder: diagn. and treatment ( s/e)challenges ED: diagn. and treat.(weight) challenges Pt’s preference for a/depr.
11 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.
12 Danger of missing BD Unopposed Antidepressant therapy: Rapid Cycling - 23 % (Ghaemi et al, 2000)Manic episode- 55% (Ghaemi et al, 2000)Mixed EpisodesPsychotic EpisodesAntidepressants Side EffectsNon adherence to treatmentAny diagnosis of MDD has to be provisional given high prevalence of switch to mania.
14 Mixed EpisodeThe criteria are met both for a Manic Episode and for a Major Depressive Episode for at least 1 weekSevere enough to cause marked impairment in occupational functioning or in usual social activities.

28 “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
29 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.
30 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?
32 MDQ: scoring and interpretation Answering “Yes” to 7 or more of the events in question #1,answering “Yes” to question #2, andanswering “Moderate problem” or “Serious problem” to question #3is considered a positive screen for BDPsychiatric Patient sample:Sensitivity: 73%Specificity: 90%Community Sample:Sensitivity 28%Specificity 97%(Zimmerman,et al, 2004)
33 Bipolar Spectrum Diagnostic Scale Total scoreLikelihood of BD<6Very unlikely6-10Low probability11-18Moderate probability19 or higherHighly likelyBSDS is a descriptive story- subtle features of bipolar illnessAddresses the concept of BDEach 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”.
34 Bipolar Spectrum Diagnostic Scale (BSDS) Sensitivity bipolar I : 75%Sensitivity bipolar II / NOS : 79%Overall Specificity : 85%(Ghaemi et al, 2005)
37 Acute management of Bipolar Depression 1st line : Lithium, lamotrigine, quetiapine, quetiapine XR, lithium or divalproex+SSRI, olanzapine+ SSRI, lithium or divalproex + bupropion2-nd line: Quetiapine + SSRI , adjunctive modafinil.Not recommended: Gabapentin , aripiprazole monotherapyEfficacy 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)
38 New ApproachesHPI axis dysregulation- rationale for antiglucocorticoid treatmentGlucocorticoid receptor antagonist- mifepristone-1 week improved:spatial memoryverbal fluencydepressive symptoms (MADRS) (Gallagher et al, 2009)
39 Ketamine in Treatment Resistant Bipolar Depression Novel mechanism of action- antagonist of NMDA receptorsTargerts glutamate, major excitatory neurotransmitter in the brain163 patients with TRD studied25-85% response rate 24 hrs post infusion14-70% response rate 72 hrs post infusion(Rot et al 2012)
40 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 371% of subject responded to ketamine and 6% to placebo during the trial(Diazgranados et al 2010)
42 Asenapine Preclinicaly: Involves wide spectrum of receptors Improves hedonia, sleep architecture in animal model (Blier, 2012)3 week random. mania trial – significant-day2Comparable 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
43 AsenapineAsenapine in combination with Lithium or divalproex –superior efficacy over mood stabilizers aloneSide effects:Anxiety, somnolence (dose related?)well tolerated in patients with BD-INo change in prolactine level (Citrome et al, 2009)
44 Difference in acute treatment of depressive, manic and mixed episodes requires accuracy in diagnostic impression.
45 Maintenance pharmacotherapy of BD 1-st line: Lithium, lamotrigine (depression only?), divalproex, olanzapine, quetiapine, lithium or divalproex +quetiapine, risperidone, aripiprazole, ziprazidoneAsenapine (Sycrest) In 40 weeks trial asenapine >olanzapine (Grunze, 2012)Not recommended: Adjunctive flupenhtixol, monotherapy with gabapentin, topiramate and a/depressants

48 MAPS programCombined Psychoeducation, CBT and Social Rhythms approaches including:M- monitoring mood and activitiesA- assessing prodromesP- preventing relapseS- SMART goal setting(specific-measurable-actionable-realistic-time bound)
49 Circadian rhythm (CR) instability Multiple competing inputs for CR advance/delaytiming of work/choresmealssocial contactsIn vulnerable individuals, changes in social time cues could lead to disruption in CR and ultimately to relapse
50 Sleep disturbance in BD The most evident “symptom” of CR disruption is the disturbance of sleepManaging sleep is fundamental priority in BD because:Sleep deprivation may trigger maniaPersistent sleep disturbance is commonAltered sleep may be a predictor of relapseAlteration in sleep-wake cycle may have harmful effects on general health, incl. weight gain and insulin resistance
51 Interpersonal and Social Rhythm Therapy (IPSRT) IPSRT has been shown to:speed time to remission of bipolar depressionprolong remission of an affective episodereduce suicide attemptsimprove occupational functioning(Mildowitz et al, 2007)
52 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 attentionLT may corect circadian phase disturbance contributing to both subjective and objective dysfunction in adult ADHD independently of mood improvement ( Rybak et al, 2006)
53 CBT for BDEducation:initial stage, engagement, most of pts know very littleBehavioral interventions:taking actions to control sx - monitoringavoid exacerbating stimuliCognitive component:twisted thinkingChain analysis
54 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?
55 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 maniaInteractive CBT program: https://moodgym.anu.edu.au
