19 Additional Defining Criteria Symptom SpecifiersAtypicalMelancholicChronicCatatonicPsychoticMood congruent/ incongruentPostpartumAtypical – Oversleep, overeat, weight gain, anxietyMelancholic – Severe depressive and somatic symptomsChronic – Major depression only, lasting 2 yearsCatatonic – Absence of movement, very seriousPsychotic – Mood congruent hallucinations/delusionsMood incongruent features possible, but rarePostpartum – Manic or depressive episodes after childbirth
20 Additional Defining Criteria Figure 7.3 Mood disorders and specifiers for the most recent episode of the disorder
21 Additional Defining Criteria Course SpecifiersLongitudinal courseRapid cycling patternSeasonal patternDepression vs. maniaMelatoninPhototherapyCBTTechnology Tip: Visit the Mayo Clinic site for more information on SAD:Longitudinal course specifiers are used to address whether a person has had a past episode of depression or mania and whether the person recovered fully from past episodes. For example, one should determine whether dysthymia preceded a major depressive episode or whether cyclothymic disorder preceded bipolar disorder. Both scenarios tend to decrease chances of recovery and increase length of treatment.Rapid cycling pattern applies only to bipolar I and II disorders. Rapid cycling pattern is used when a person has at least 4 manic or depressive episodes within a period of 1 year. Rapid cycling is a more severe form of bipolar disorder that does not respond well to treatment, and appears to be associated with higher rates of suicide. Alternative drug treatments (e.g., anticonvulsants, mood stabilizers) are typically utilized with individuals meeting criteria for this specifier.Seasonal pattern applies to bipolar disorders and recurrent major depression and is used to indicate whether episodes occur during certain seasons, usually wintertime. Those with winter depressions display excessive sleep and weight gain. Seasonal affective disorder may be related to circadian and seasonal changes in the increased production of melatonin (i.e., a hormone secreted by the pineal gland). Phototherapy is a recommended effective treatment for this condition.
22 Prevalence of Mood Disorders Table 7.3 Prevalence of mood disorders
23 Prevalence of Mood Disorders Children and AdolescentsSimilar to adultsSymptom presentationsPrevalenceEarly childhoodAdolescenceMisdiagnosisADHDConduct disorderTechnology Tip: For more information, visit the NIMH site:Children fundamentally similar to adults; no childhood mood disorders in the DSM-IV-TR. Children less than 9 years of age show more irritability and emotional swings rather than classic manic states, and are often mistaken as hyperactive.Depressive disorder occurs less often in children than adults but that this difference closes somewhat during adolescence, where depression becomes more frequent compared to adults. Bipolar disorder is rare in childhood, but rises substantially in adolescence and so does suicide.
24 Prevalence of Mood Disorders ElderlyPrevalence may depend on settingSymptom profileFemale : Male = 1:1Diagnostic difficultyComorbiditiesTechnology Tip: For more information, visit the following sites: ;Elderly - 18% to 20% of nursing home residents, likely to be chronic.Symptoms- sleep problems, hypochondriasis, and agitation.Diagnostic difficulty- medical illnesses and symptoms of dementia; menopause for womenPrevalence - MDD is the same or slightly lower as in the general population.Comorbidities- GAD and panic disorder (33%), alcohol (33%),Gender - imbalance in depression disappears after age 65.
25 Prevalence of Mood Disorders Across CulturesSimilar prevalence among US subculturesExceptionsPhysical or somatic symptomsComparabilityExceptions – Native American village depression was 1.5 to 4x higher than general population; SES and stressSymptoms- weakness, tirednessComparability – constructs, statements, wording

50 Treatment : Antidepressant Medications Tricyclics (Tofranil, Elavil)Frequently used for severe depressionBlock reuptake/down regulateNorepinephrineSerotonin2 to 8 weeks to workMany negative side effectsLethalitySide effects - blurred vision, dry mouth, constipation, difficulty urinating, drowsiness, weight gain, and sexual dysfunction. Because of the side effects, about 40% of patients stop taking the drugs.Efficacy -tricyclics alleviate depression in 50% of cases to as high as 65% to 70% of cases.Technology Tip: Info on pharmacological treatments for depression can be found at:
51 Treatment : Antidepressant Medications Monoamine Oxidase (MAO) InhibitorsBlock MAOHigher efficacyFewer side effectsInteractionsFoodsMedicinesSelective MAO-IsMonoamine Oxidase (MAO) - Enzyme that breaks down serotonin/norepinephrineEfficacy- slightly more effective than tricyclics and have fewer side effects.However, ingestion of tyramine foods (e.g., cheese, red wine, beer) or cold medications with the drug can lead to severe hypertensive episodes and occasionally death. New MAO inhibitors (not yet widely available) are more selective, short acting, and do not interact negatively with tyramine. MAO inhibitors are usually prescribed only when tricyclics prove to be ineffective.
52 Treatment : Antidepressant Medications Selective Serotonin Reuptake InhibitorsFluoxetine (Prozac)First treatment choiceBlock presynaptic reuptakeNo unique risksSuicide or violenceMany negative side effectsSide effects - physical agitation, sexual dysfunction or low desire, insomnia, and gastrointestinal upset.
