Back to Basics: Mood Disorders Dr. Valerie Primeau PGY5 Psychiatry April 5th, 2013 [email protected] MCC Objectives (1) Distinguish between the normal condition of sadness (e.g., bereavement) and the presence of one of the clinical syndromes (e.g., depressive disorders). Through efficient, focused, data gathering: List and interpret critical clinical and laboratory findings which were key in the processes of exclusion, differentiation, and diagnosis: Diagnose the presence of depression (depressed mood, loss of interest in all activities, change in weight/appetite, sleep, energy, libido, concentration, feeling of hopelessness, worthlessness or guilt, recurrent thoughts of suicide, increase in somatic complaints, withdrawal from others). Determine intensity and duration (weeks or years) of depression, antecedent event, and its effect on function. Determine whether a general medical condition is present, use or abuse of drugs (or withdrawal). Examine for slowness of thought, speech, motor activity or signs of agitation such as fidgeting, moving about, hand-wringing, nail biting, hair pulling, lip biting; examine vital signs, pupils, and skin for previous suicide attempts, stigmata of drug and/or alcohol use, thyroid gland, weight loss. Elicit history of elevated, expansive or irritable mood (for at least 1 week) with impairment in function or without impairment and lasting only 4 days. Select patients only when high index of suspicion requires further investigation for medical condition or drugs that affect mood (e.g., thyroid function, toxicology screen, electrolytes, etc.). Conduct an effective initial plan of management for a patient with a mood disorder: Outline and describe treatment available for mood disorders under categories of medications, physical treatment, and psychologic treatment. Select patients in need of specialized care.

Robinson, Psychiatric Mnemonics & Clinical Guides, 1998 General Concepts Important tips! All Mood Disorders must cause clinically significant distress of impairment in social, occupational, or other important areas of functioning DDx always includes substance use or a general medical condition Cognitive behavioral therapy is indicated for almost everything Know the name and the starting dose of at least one medication of each class ex: citalopram 10 mg Lifetime Prevalence Major Depressive Disorder Women = 10-25% Men = 5-12% Dysthymia = 6% Bipolar Disorder Type I = 0.4-1.6% Type II = 0.5% In a family practice setting Depression is one of the top five diagnoses made in the offices of primary care physicians 25% of all patients who visit their family physicians will have a diagnosable mental disorder The incidence of major depression is 10% in primary care patients Effective treatment can reduce morbidity and decrease utilization of other health services Medical patients with major depression have a worse prognosis for their medical recovery History taking – Key Points (1) Mood Disorders are usually episodic An episode is demarcated by either Switch to an opposite state ex: manic depressive Two months or more of partial or full remission after an episode Inquire about current episode, but also past episodes Confirm the diagnosis Evaluate past response to treatment Evaluate prognosis (inter-episode wellness) History taking – Key Points (2) Inquire about substance use and medications Ask about family history and if positive, ask which treatment was effective Always ask about safety issues! Major Depressive Episode (1) 5 or more for 2 weeks nearly every day: Mood depressed* Sleep ↑↓ Interest ↓, libido ↓, social withdrawal* Guilt, hopelessness, worthlessness Energy ↓ Concentration ↓, indecisiveness Appetite↑↓, weight ↑↓, loss of taste for food Psychomotor ↑↓ Suicidal ideation, recurrent thoughts about death Major Depressive Episode (2) Many patients with depression do not report feeling depressed, but will have loss of interest Elderly patients often have new onset of somatic complaints but may deny feeling depressed Patients can also present with panic attacks or obsessive-compulsive symptoms Physical symptoms (sleep, appetite, energy level, psychomotor activity) are often referred to as “vegetative symptoms” New onset of these symptoms can be a good predictor to antidepressant response Manic Episode (1) Abnormal persistent elevated, expansive or irritable mood lasting at least one week Any duration if hospitalization is required At least 3 of (4 if mood is irritable) Distractibility Indiscretion, pleasurable activities with painful consequences Grandiosity Flight of ideas Activity ↑ Sleep ↓ Talkativeness Manic Episode (2) Mood disturbance is Causing marked impairment in functioning Severe enough to necessitate hospitalization to prevent harm to self or others or Accompanied by psychotic features Manic-like episodes induced by a medical condition, substance or medication do not count towards Bipolar Affective Disorder Hypomanic Episode Same criteria of Manic Episode except Duration > 4 days, < 7 days Unequivocal change in mood and functioning from baseline, observable by others Change in function is not severe enough to cause marked impairment in social or occupational functioning or to necessitate hospitalization Absence of psychotic features Mixed Episode Criteria met for both Manic and Major Depressive Episodes Nearly everyday for one week Mental State Examination Psychomotor retardation, catatonic features Psychomotor agitation such as fidgeting, moving about, hand-wringing, nail biting, hair pulling, lip biting Speech (slow pressured) Affect Type (depressed euphoric) Lability Range (flat expansive) Reactivity Thought process (paucity of content flight of ideas) Thought content (worthlessness, hopelessness, grandiosity, psychotic features, suicidal or homicidal ideation) Cognition, distractibility Insight, judgment Physical Examination Vital signs Weight Skin (look for previous suicide attempt) Stigmata of drug and/or alcohol use Thyroid gland Cardiopulmonary GI including liver Neurological exam (pupils) Laboratory Workup CANMAT = when clinically indicated Routine screening Complete blood count Thyroid function test Liver function test Electrolytes B12, folates Urinalysis, urine drug screen Additional screening Neurological consultation CXR EKG CT-scan Common Medical Conditions Associated With Mood Disorders Pulmonary disease (COPD, asthma) Endocrine disorders (Hypo/hyperthyroidism, diabetes) Cancer Cardiovascular disease, especially MI CNS (migraine, infection, tumour, stroke, head injury, hypoxia) Neurological disorders(Epilepsy, Parkinson's, Huntington's, Multiple Sclerosis) B12, folate deficiency Chronic pain, back problems Sleep apnea Drugs Commonly Associated With Mood Disorders Antidepressant & somatic treatments for depression Manic “switch” FDA warning, increased suicidality in adolescents Psychostimulants Steroids, corticosteroids Isotretinoin (Accutane) Oral contraceptives, progesterone Interferon A Parkinson’s Disease agents (mostly psychotic symptoms) Specific Mood Disorders Major Depressive Disorder (1) Mean age of onset = 30 years 50% of all patients have an onset between the ages 20-50 At least 1 Major Depressive Episode Not better accounted by another disorder, medical condition or substance No Manic, Hypomanic or Mixed episode Major Depressive Disorder (2) Etiology Genetics (65-75% monozygotic twins) Neurotransmitter dysfunction Psychosocial Low self-esteem Negative thinking Environmental ex: acute stressor Co-morbid psychiatric disorders ex: substance use Major Depressive Disorder (3) Risk factors Female > Male Age (20-50 years old) Rural > urban areas Positive family history Childhood experiences (loss of parent before age 11, abuse) Personality structure Recent stressors ex: loss of spouse, unemployed Postpartum Lack of support network Major Depressive Disorder (4) Treatment Pharmacotherapy (ie SSRIs, SNRIs…) Electroconvulsive therapy Light therapy if seasonal component Psychotherapy Cognitive behavioral therapy Interpersonal therapy (grief, transitions, interpersonal conflicts or deficits) Social Vocational rehabilitation Social skills training Major Depressive Disorder (5) Light to moderate Psychotherapy, medication depending on patient preference Moderate to severe Medication with or without psychotherapy, electroconvulsive therapy (ECT) Depression with psychotic features Combination of antidepressant and antipsychotic, gold standard is ECT Major Depressive Disorder (6) Treat until remission is complete Duration of untreated illness affects future treatment response (untreated depression can last 6-12 months) Maintain treatment to prevent relapse (at least 6-12 months for a first episode) 50% recurrence after 1 episode 75% after 2 episodes > 90% after 3 episodes Major Depressive Disorder (7) Up to 15% of patients with Mood Disorders will die by suicide Prognosis at 1 year 40% still meet criteria 20% have partial symptoms 40% have no mood disorder Particularities of Depression With Atypical Features With Melancholic Features With Catatonic Features With Psychotic Features With Seasonal Pattern With Postpartum Onset Grief & Bereavement With Atypical Features Mood reactivity Mood brightens in response to actual or potential positive events At least two of ↑ appetite (carbohydrate cravings), weight gain Hypersomnia Leaden paralysis (heavy, leaden feelings in arms or legs) Long-standing pattern of interpersonal rejection hypersensitivity With Melancholic Features At least one of Anhedonia (inability to find pleasure in positive things) Lack of mood reactivity (mood does not improve with positive events) At least three of Distinct quality of depression subjectively different from grief Depression regularly worse in the morning Early morning awakening (at least 2 hours) Marked psychomotor agitation or retardation Severe anorexia or weight loss Excessive or inappropriate guilt With Catatonic Features At least two of Motor immobility as evidenced by catalepsy (including waxy flexibility) or stupor Excessive motor activity (purposeless, not influenced by external stimuli) Extreme negativism (motiveless resistance to all instructions or maintenance of a rigid posture against attempts to be moved) or mutism Peculiarities of voluntary movement as evidenced by posturing, stereotyped movements, prominent mannerisms, or prominent grimacing Echolalia or echopraxia (automatic repetition of vocalizations or movements made by another person) With Psychotic Features Psychosis may be present in 10-15% of patients with a Major Depressive Episode Associated with worse prognosis Increase risk of suicide and homicide Treatment implications Antidepressant + antipsychotic Consider ECT With Seasonal Pattern Only applies to a Major Depressive Episode Regular temporal relationship between onset of Major Depressive Episode and a particular time of year, usually fall or winter Full remission (or switch to mania) also occurs at a regular time of year, usually spring In the last 2 years, 2 Major Depressive Episodes have occurred as above with no nonseasonal episode Seasonal Major Depressive Episodes outweigh non-seasonal episodes in their lifetime With Postpartum Onset 10% of postpartum women Etiology likely a combination of neuroendocrine alterations and psychosocial adjustments Onset has to be within 4 weeks after childbirth (DSM) Distinguish from the “baby blues” (70%) During 10 days postpartum, transient, not impairing functioning Severe ruminations or delusional thoughts about the infant is associated with significantly increased risk of harm to the infant Command hallucinations to kill the infant Delusional belief that the infant is possessed Grief & Bereavement (1) Normal grief or bereavement reaction versus Major Depressive Episode Complicated or pathological grief or bereavement (not in DSM-IV) Grief & Bereavement (2) DSM-IV = Normal grief reaction can present with depressive symptoms as long as it is < 2 months Red flags that point towards Depressive Disorder Feelings of guilt not related to the loved one's death Thoughts of death other than feelings he or she would be better off dead or should have died with the deceased person Morbid preoccupation with worthlessness Marked psychomotor retardation Prolonged and marked functional impairment Hallucinations other than thinking he or she hears the voice of or sees the deceased person Dysthymic Disorder (1) Female > Male (2-3:1) Depressed mood for at least 2 years, most days than not Never without the symptoms for more than 2 months at one time No Major Depressive Episode is present for the first 2 years Treatment with psychotherapy ± antidepressants Dysthymic Disorder (2) Hopelessness Energy ↓ Self-esteem ↓ 2 years of depressed, for more days than not (1 year in kids, mood can be irritable) Sleep ↑↓ Appetite ↑↓ Decision-making ↓, concentration ↓ Bipolar Disorder (1) Bipolar I Disorder = at least 1 Manic or Mixed Episode Bipolar II Disorder = at least 1 Major Depressive Episode & 1 Hypomanic Episode Commonly have more Major Depressive Episodes but not required for diagnosis No past Manic or Mixed Episode Not better accounted by another disorder, a general medical condition, a substance or medication “Bipolar Disorder type III” Will change in DSM-V Bipolar Disorder (2) Male = Female (1:1) Age of onset teens to 20s Average age for first Manic Episode = 32 Family history of a major Mood Disorder in 60-65% of patients with Bipolar Disorder Untreated Manic Episode can last 3 months Untreated Major Depressive Episode can last 6-13 months Bipolar Disorder (3) Pharmacotherapy (Bipolar I) Acute Manic Episode Acute Major Depressive Episode Lithium, divalproex, olanzapine,risperidone, quetiapine, quetiapine XR, aripiprazole, ziprasidone Taper and discontinue antidepressants Lithium, lamotrigine, quetiapine, quetiapine XR Do not use antidepressant as monotherapy Maintenance treatment Lithium, lamotrigine(limited efficacy in preventing mania), divalproex, olanzapine, quetiapine, risperidone LAI,aripiprazole (mainly for preventing mania) With Rapid Cycling Can be applied to Bipolar I and II At least 4 mood episodes in previous 12 months (Major depressive, Manic, Hypomanic or Mixed episodes) Episode demarcated by either switch to the opposite state or 2 months of partial or full remission between episodes Rapid cycling diagnosis has treatment implications Cyclothymia Numerous periods of hypomanic and depressive symptoms for at least 2 years Never without symptoms for more than 2 months No Major Depressive, Manic or Mixed episodes No evidence of psychotic symptoms Ethics and Legal Considerations Consent to Treatment (1) MCC objectives: Patients who are depressed can meet the criteria for decision capacity, but their preferences are clouded by their mood disorder Overriding the wishes of a seemingly capable patient who is depressed is a serious matter and is one situation in which psychiatric involvement should be sought Decisions to limit care should be deferred if possible until depression has been adequately treated Consent to Treatment (2) MCC objectives (continued): If time pressures dictate the need to make a prompt choice, the physician should seek surrogate involvement If the surrogate has previously discussed the patient's wishes at a time when he or she was not depressed, the surrogate will be able to explain whether the patient's choice is consistent with previously stated beliefs or has changed since the onset of depression Consent to Treatment (3) Specific to the issue Informed Voluntary Capable – no misrepresentation – no coercion or persuasion Consent to Treatment (4) Diagnosis and nature of treatment Purpose of proposed treatment Anticipated risks and benefits of treatment Alternative treatments and their risks and benefits Prognosis, with and without treatment Duty to Warn & Protect Criteria for involuntary admission Serious bodily harm to himself/herself Serious bodily harm to
