Mood Disorders • Unipolar Mood Disorders: • Major Depression • Dysthymia • Mania • Bipolar Disorder
Major Depression • Cognitive symptoms • Physical symptoms- psychomotor retardation; sleep changes, appetite changes • Loss of interest/inability to experience pleasure
Mania • Elation, euphoria, hyperactivity, agitation • Grandiosity • Rapid speech, incoherence: “flight of ideas” • Risky behavior • Hypomanic episode- less severe/risky than mania
Major Depression • Initial diagnosis- single episode • Rare; typically recurs- 85% later experience a second episode • Major Depressive Disorder, Recurrent • Median- four episodes over the lifespan • Each episode- average of 4-5 months
Dysthymic Disorder • Depressive symptoms more mild than Major Depression • 2 years or longer, without being symptom free for longer than 2 months
“Double Depression” • Major Depressive episodes occurring with Dysthymic Disorder • High rate of relapse/recurrence
Onset of Major Depression • Increased risk during adolescence • Trend: Depression is occurring at earlier ages, worldwide
Understanding Grief • Following the loss of a loved one, symptoms of depression are common • Concerning symptoms: • Prolonged depression • Psychotic features • Suicidal ideation
Bipolar Disorder • Manic episodes alternate with Major Depressive episodes • Bipolar I: entails full manic episodes • Bipolar II: entails hypomanic episodes (less severe)
Bipolar Disorder • Average age of onset for Bipolar I- 18 years • Average age of onset for Bipolar II: 19-22 • Can begin in childhood • Relatively rare to develop after 40
Specifiers: Additional Defining Criteria • Catatonic features • Psychotic features • Postpartum onset • Seasonal patterns: (SAD) • Rapid cycling (noted in 20-40% cases of bipolar disorder)
Mood Disorders in Children and Adolescents • Manic states may be classified by more irritability/agitation vs. adults • Children, particularly boys: depression may be accompanied by aggression and conduct problems
Major Depression in Elderly Populations • Increase in physical problems accompanied by a reduction in social support • Suicide rates are highest in elderly groups
Mood Disorders:Causes • Biological: twin/family studies- strongly heritable • Neurotransmitters: lower levels of serotonin, other neurotransmitters vary more widely as a result • Psychological: diathesis-stress model; trauma • Social: marital relationships, work difficulties, social support
Learned Helplessness • Depressive Attribution Style • Internal: attributes negative events to personal shortcomings • Stable: other bad things will still be my fault • Global: negativity across a range of issues
Mood Disorders: Treatment • Antidepressants: Tricyclic, MAO inhibitors,Serotonin-specific reuptake inhibitors • Research: anti-depressants and suicide • Lithium: treatment of Bipolar Disorder • Toxicity • 50% of individuals with Bipolar Disorder respond well
ECT • Electroconvulsive Therapy • Controversial approach- used much less frequently
Psychological Treatment • Cognitive-Behavioral Therapy • Combined Approaches • Treatment of Bipolar Disorder: • Regulation of sleep cycles and daily routines, nutritional regimens • Treating the family: • Family involvement lessens the relapse rate
