Mood Disorders and Suicide
            Mood Disorders
• Characterized by emotional extremes
  – Unusually severe or prolonged
  – Impairs one’s ability to function
    Major Depressive Disorder
            (MDD)
• Mood disorder in which a person, for no
  apparent reason, experiences 2+ weeks of:
  – Depressed moods
  – Feelings of worthlessness
  – Diminished interest/pleasure in most activities
• Major depression - #1 reason people seek
  help from mental health specialists
      Major Depressive Disorder
             (continued)
• Symptoms:
  –   Poor appetite
  –   Insomnia/sleep much of the time
  –   Lethargy
  –   Feelings of worthlessness
  –   Loss of interest in family, friends and activities
    Major Depressive Disorder
           (continued)
• Depression can be brought on by:
  – Situational cues (laid-off/fired, ending of a
    relationship, etc.)
  – No apparent cause
• Depressed people are especially:
  – Sensitive to negative happenings
  – Expect negative outcomes
  – Are more likely to recall negative information
    Major Depressive Disorder
           (continued)
• Some facts about major depression:
  – Women are 2x’s as vulnerable as men
     • 10-25% as opposed to 5-12%
  – If untreated, most episodes last (3?) 6 months
    or less; some episodes have lasted 2+ yrs.
  – Young adults in America are 3x’s more likely
    to develop depression than their grandparents
    Major Depressive Disorder
           (continued)
• More facts
  – Stressful events (work, marriage, etc.) often
    precede depression
  – Average age of onset - mid-20’s (can occur at
    any age); lowest onset – 65 and older
  – 15% of people suffering from severe depression
    commit suicide
    Major Depressive Disorder
           (continued)
• More facts:
  – Some people experience a single major
    depressive episode; most experience multiple
    episodes/lifetime
  – The more episodes you have, the more you are
    likely to have
  – About 2/3’s of the depressed pop. eventually
    experience no more episodes; it is chronic in
    about 1/3 of the depressed pop.
    Theoretical Perspectives in
      Depressive Disorders
• Stress
  – Stressful situations  depression
     • Loss of job, relationship, financial difficulties, etc.
• Psychodynamic – self-focusing model
  – In times of loss, some people become self-
    absorbed
     • Focusing only on one’s loss  depression
    Theoretical Perspectives in
      Depressive Disorders
• Humanistic
  – Loss of meaning in one’s life  not striving
    toward self-actualization  guilt  depression
  – Depression can result when our self esteem
    takes a hit  Loss of self-worth
• Learning
  – Lack of reinforcement  lack of motivation 
    depression; Seligman’s learned helplessness
    Theoretical Perspectives in
      Depressive Disorders
• Cognitive
  – Cognitive triad of depression
     • Negative view of oneself
     • Negative view of the environment
        – Excessive demands, things too difficult to overcome, etc.
     • Negative view of the future
• Biological
  – Less activity in prefrontal cortex
    Theoretical Perspectives in
      Depressive Disorders
• Biological
  – Depression may be caused by abnormalities
     • In metabolism
     • In the release and/or transmission of serotonin or
       norepinephrine
   Seasonal Affective Disorder
• Mood swings that are consistent with the
  changing of the seasons (esp. from summer
  to fall and winter)
• Cause  unknown
  – Could be related to decrease in serotonin
    production during fall/winter months
  – Could be a result of less sunlight/more darkness
    during the fall/winter months
   Seasonal Affective Disorder
          (continued)
• Behavioral characteristics:
  –   Fatigue/lethargic
  –   Excessive sleeping
  –   Craving carbohydrates

   Seasonal Affective Disorder
          (continued)
• Standard Treatment:
  – 30 min. of 10,000-lux, diffused white
    fluorescent lighting
     • Usually admin. daily, early in morning
  – Seems to relieve symptoms, though we don’t
    know why
     • Full remission in almost 50% of patients
     • Rate climbs to 80% if tailored to sleep-wake cycle
  Postpartum Depression (PPD)
• Onset of mood changes after the birth of a
  child
  – Hormonal changes often cause new mothers to
    experience mood swings
     • Onset must occur within 4 weeks of childbirth
  – Women with postpartum depression suffer
    mood swings for months to 1+ yrs (usually not
    as severe as major depressive disorder)
         Postpartum Depression
              (continued)
• Behavioral characteristics of PPD:
  –   Low self-esteem
  –   Poor appetite
  –   Sleep disturbances
  –   Difficulty concentrating/getting motivated

    for at least two years
     • In children, it need only last 1 year to be
       characterized as dysthymic disorder
  – Person feels down in the dumps most of the
    time (E.g.: Eeyore from Winnie the Pooh)
         Dysthymic Disorder
             (continued)
• Differs from MDD in that:
  – The onset usually occurs during childhood or
    adolescence
  – Onset occurs gradually; usually chronic with
    episodes lasting for years
  – Less severe; usually doesn’t interfere with
    normal functioning
           Dysthymic Disorder
               (continued)

   – Both manic and depressive episodes occur almost daily
            Bipolar Disorder
              (continued)
• During the manic phase the person may
  display some or all of the following:
  – Over-talkative; rapid speech (pressure speech);
    speech is loud, flighty (rapid flight of ideas)
    and difficult to interrupt
  – Overactive (but irritated by others telling them
    to slow down)
  – Elated
  – Have little need to sleep
         Bipolar Disorder
           (continued)

     Cycling Through Bipolar
             Disorder
• Usually, bipolars will cycle through manic
  and depressed periods (lasting a few weeks
  to several months in duration) 2 or 3 times
  per year
  – Some bipolars are “rapid cyclers;” they
    experience 2 or more full cycles with no normal
    mood periods in between (very rare)
       The Stuff Of Geniuses?
• In milder forms of mania, the energy and
  free-flowing thinking can fuel creativity.
  – Many famous people have been diagnosed with
    bipolar disorder
     • Van Gogh, Ben Stiller, Carrie Fisher, Margot
       Kidder, Linda Hamilton, Martin Lawrence, Sting,
       Axl Rose, DMX, Bobby Brown, etc.
        – It has been speculated that Beethoven and Thomas
          Jefferson also had bipolar disorder
    Theoretical Perspectives in
        Bipolar Disorders
• Psychodynamic
  – Dominance shifts between ego and superego
• Biological
  – New theory – certain chromosomes may
    predispose one to bipolar disorder
  – Diathesis-stress model
     • Stress + biological influences + predisposition
        Cyclothymic Disorder
• Must last at least 2 yrs:
   – Manic symptoms are not severe enough to be
     labeled as manic episodes
   – Depressive symptoms are not severe enough to
     be labeled as major depressive episodes
   – Symptom-free periods last less than 2 months
   – Person is often regarded as temperamental,
     moody, unpredictable, inconsistent or
     unreliable
     Theoretical Perspectives:
        Additional Factors
• Genetics:
  – 52% of people with MDD have a relative who
    suffers from some type of mood disorder
  – 86% of people with bipolar disorder have a
    relative who suffers from some type of mood
    disorder
  – When one monozygotic twin has a mood
    disorder there is a 70% chance the twin will too

  24 hours
