Mood Disorders and Schizophrenia

  1. Mood Disorders
    psychological disorders characterized by emotional extremes

    Two principle forms:

    1. major depressive disorder

    • 2. bipolar disorder
    • manic-depressive disorder

  2. Major Depressive Disorder
    3/5 signs of depression:

    1. lethargy (lack of energy or enthusiasm)

    2. feelings of worthlessness

    3. loss of interest in family, friends, activities

    lasting two or more weeks

    anguish of grief +sluggishness of jet lag
  3. Bipolar Disorder
    alternating between depression and mania

    • manic characteristics:
    • overtalkative, overactive, elated, fewer inhibitions->poor judgement and reckless behavior

    • People w/bipolar disorder:
    • Walt Whitman
    • Mark Twain
    • Ernest Hemingway
    • George Handel
    • Robert Schumann
  4. Understanding Mood Disorders
    Many behavioral and cognitive changes accompany depression.

    Depression is widespread

    Compared with men, women are nearly twie as vulnerable to major depression.

    Most major depressive episodes self-terminate

    Stressful events related to work, marriage, and close relationship often precede depression

    With each new generation, depression is striking earlier(now often in teens) and affecting more people
  5. The Biological Perspective
    Areas of funded interest: genetic predispositions, brain activity, and biochemical imbalance

    • Genetic Influences
    • Mood disorders increase if a parent or sibling has a disorder
    • linkage analysis-examined DNA from effected and uneffected family memers; points to chromosome area

    • The Depressed Brain
    • Left frontal lobe likely to be inactive during depressed state

    Norepinephrine(increases arousal, boosts mood) scarce during depression, overabundant during mania

    Seratonin scarce during depression; protein controlling seratonin activity
  6. Socia-Cognitive Perspective
    Self-defeating beliefs and negative explanatory style

    • Negative Thoughts and Negative Mood Interact:
    • self-defeating beliefs->learned helplessness

    • Depression's Vicious Cycle
    • Negative, stressful event ->negative explanatory style->
    • depressed mood->cognitive and behavioral changes->(fuels negative experience again)
  7. Schizophrenia
    group of severe disorders characterized by disorganized and delusional thinking, disturbed perceptions, and inappropriate emotions and actions

    1 out of 100 will develop schizophrenia
  8. Symptoms of Schizophrenia
    literally meaning "split mind"

    • Disorganized Thinking
    • disorganized thoughts--breakdown of selective attention
    • delusions
    • paranoid tendencies
    • Disturbed Perceptions
    • hallucinations(sensory experiences without sensory stimuation)

    • Inappropriate Emotions and Actions
    • inappropriate actions
    • --laughing after talking about death
    • or
    • lapse into emotionless state of flat affect
  9. Onset and Development of Schizophrenia
    can strike as early as young people going into maturation to adulthood

    • positive symptoms: halluncinations, disoriented talk, inappropriate emotions
    • negative symptoms: toneless voice, expressionless face, mute and rigid bodies
    • --postive symptoms presence of inappropriate behavior
    • --negative symptoms absence absence of appropriate behavior
