mood disorders overview
Mood Disorders Overview
  • Symptoms, onset, prevalence (Depression, Bipolar)
  • Causes (Depression, Bipolar)
  • Suicidality
  • Treatment of Depression
  • Treatment of Bipolar
depressive disorders
Depressive Disorders
  • There are several types:
    • Major depression
    • Dysthymia
    • Double depression

Sleep changes

Psychomotor agitation or retardation

Fatigue/loss of energy

Feelings of worthlessness or excessive guilt

Concentration problems

Thoughts of death, suicide, or suicide attempt

Distress or impairment

Not associated grief

Symptoms of Major Depression
onset and duration
Onset and Duration
  • Age of onset = 25 years
  • Avg episode length = 6 months
  • Recurrent, especially w/ early onset (50, 70, 90)
  • Median # of episodes = 4
  • Most no treatment
  • Earlier onset = poorer prognosis, more chronicity, worse response to treatment
gender differences
Gender Differences
  • Equal among boys and girls
  • 2:1 women
  • 25% female lifetime prevalence (12% male)
historical changes
Historical Changes
  • Depression in youth increased 10x (2 generations)
    • Age of onset is decreasing
    • 25% of those aged 18-29 one episode (2003)
  • Symptoms vary by age and culture
cultural differences
Cultural Differences
  • African American rates similar to Caucasian
  • Asian Americans lowest rates
    • 0.8% report lifetime prevalence
    • 0.8% dysthymia
  • Less common among recently immigrated Hispanics vs. Hispanic Americans (who have rates similar to Caucasians)
    • Can cope better? Stress of immigration?
  • Chronic (2 years)
  • Same symptoms, but less severe (but still debilitating)
  • Entire life
  • Lifetime prevalence 6%
  • Few seek treatment
    • Personality?
seasonal affective disorder
Seasonal Affective Disorder
  • Develops in late fall/early winter
  • Remits in spring
  • Prevalence = 3%
  • Length of day/avg temp?
  • Iceland low (expect high)
  • Changes in hormone with seasons?
    • Melatonin up in winter
postpartum depression
Postpartum Depression
  • During first few weeks post-delivery
  • (not postpartum blues - 50-80%)
  • Massive hormone change as trigger?
  • Other hormone changes similar
    • Oral contraceptives, puberty, menopause
childhood depression
Childhood Depression
  • Occurring more frequently & earlier
  • Is this the same as adult depression?
    • Different cognitive/emotional development
    • Gender rates equal until teens
    • Symptom patterns look different, not as “obvious”
  • Predictive of adult depression
when depression is not depression
When Depression is Not Depression
  • Bereavement (not diagnosed up to 2 months)
  • Adjustment disorders
  • Medical conditions
    • “Depression due to a general medical condition”
  • Everyone experiences normal sadness
    • Difficulty coping, interferences with daily activities
what is bipolar disorder
What is Bipolar Disorder?
  • Experience of mania
    • Excessive energy
    • Decreased need for sleep
    • Rapid speech (pressured speech) & movement
    • Impulsive and/or dangerous behavior
      • Spending sprees, investments
      • Unsafe sexual behavior
  • Hypomania = less severe mania
what is bipolar disorder1
What is Bipolar Disorder?
  • Extreme shifts between mania & depression (days to months)
  • Lifetime prevalence = 1% - 5%
  • Equal rates across gender, culture
  • Early onset = more severe & more chronic
bipolar disorder
Bipolar Disorder
  • Avg age onset 18 (I) and 22 (II)
    • 50% patients ill before age 30 (25% by 20)
  • Course is unpredictable
  • Diagnosis is often delayed
  • 10-15% of patients commit suicide
    • 20-50% will attempt at some point
bipolar disorder in children
Bipolar Disorder in Children
  • Irritability, emotional swings
  • More chronic (not episodic)
  • Often misdiagnosed (ADHD, Conduct Disorder)
causes of depression
Biological Dimensions

Psychological Dimensions

Social and Cultural Dimensions

Integrative Theory

Causes of Depression
familial and genetic influences
Familial and Genetic Influences
  • 36-44% heritable women, 18-24% men (major depression)
  • Stronger genetic influences bipolar
familial and genetic influences1
Familial and Genetic Influences
  • Certain pattern most genetic, depression:
    • Early age of onset
    • Greater number of episodes
    • Long longest episode
    • More impairment
    • Suicidality
  • Probably polygenic
neurotransmitter systems
Neurotransmitter Systems
  • Low relative levels of serotonin
    • Serotonin = regulation of emotional reactions
  • Indirect evidence
    • Metabolites of serotonin & norepinephrine lower
    • Drugs increasing serotonin help
    • Drugs decreasing serotonin ruin the effects of antidepressants
    • Receptors abnormal (PET)
neuroendocrine influences
Neuroendocrine Influences
  • Hormonal diseases can = depression
    • E.g. Hypothyroidism
  • Cortisol (stress hormone) is elevated
    • May not be specific to depression
  • Hormones likely associated with post-partum depression
circadian rythyms sleep disturbances
Circadian Rythyms & Sleep Disturbances
  • Excess vs. lack
  • Falling asleep, waking up, early waking
  • Circadian rythym: Our normal daily pattern of biological changes (hormones)
how do depressed people sleep
How do depressed people sleep?
  • Shortened REM latency (quick)
    • Sooner, longer, more intense
  • Expense: deep sleep
    • Energy restoring
sleep disturbances
Sleep Disturbances
  • Early awakening an early marker?
  • General poor sleepers?
    • Influence treatment?
  • Sleep as predictor
    • Reduced REM latency more pronounced in absence of stressful life event
  • A biological process that can bring on depression alone?
psychological perspectives on depression
Psychological Perspectives on Depression
  • Stressful Life Events
  • Learned Helplessness
  • Negative Cognitive Styles
  • Behavioral Approaches
stressful life events
Stressful Life Events
  • Strongly related to onset
  • 80% of depressive episodes, in community samples, preceded by event
  • Stronger predictor initial episode
  • Poorer response to treatment
  • Longer recovery
  • Increased chance recurrence
stressful life events1
Stressful Life Events
  • Relationship breakup
    • 10x increase over twin
  • Humiliation
    • 20x increase in depressive episode than a twin with same genes, but no event
learned helplessness model
Learned Helplessness Model
  • Seligman’s dogs
  • Learned helplessness: depression as a result of aversive situations which we cannot control
  • Or, attributions of lack of control
learned helplessness model1
Learned Helplessness Model
  • Attributions:
    • Internal/external
    • Global/specific
    • Stable/unstable
  • Worst combination:
    • Internal + global + stable
    • “It is all my fault, always. Additional bad things will always be my fault”
cognitive model beck
Cognitive Model (Beck)
  • Development of depression
    • How do we think about ourselves?
    • How do we think about the world?
cognitive model beck1
Cognitive Model (Beck)
  • Depression = interpreting many events in negative ways
  • Cognitive errors
    • Overgeneralization
    • Arbitrary influence
cognitive model some examples
Cognitive Model (Some Examples)
  • Normal disappointments are unbearable
  • I am deficient, especially at handling stress that other people can handle
  • My future is hopeless. My stress will never end and there is nothing I can do to help
the behavioral component
The Behavioral Component
  • Behaviors reinforce/maintain depressive feelings
    • E.g. withdraw from society b/c depression leaves people with little energy
    • BUT withdrawing from society minimizes chance they will experience fun and feel better
    • A cycle -> behaviors maintain symptoms
social and cultural influences
Social and Cultural Influences
  • Marital Relations
  • Gender Differences
  • Social Support
marital relations
Marital Relations
  • Strongly related to depression
  • Marriage seems to have greater impact on men’s depression
  • Depression may erode relationships
gender differences1
Gender Differences
  • 70% of individuals with depression are women
  • Consistent across cultures
  • Uncontrollability, due to socialization?
  • Differences in rumination
  • Social disadvantages
social support
Social Support
  • Major buffer
  • Brown et al: of women experiencing a stressful event, only 10% of those who became depressed had a confidante
  • Faster recovery
causes of bipolar disorder
Causes of Bipolar Disorder
  • Biological Dimensions
  • Psychological Dimensions
  • Social and Cultural Dimensions
  • Integrative Theory
familial and genetic influences2
Familial and Genetic Influences
  • Stronger genetic than depression
  • Risk in 1st degree relatives 10x general pop.
  • Attempts to isolate genes unsuccessful
  • Depression = low levels serotonin & NP
  • Mania = high levels of NP
    • Lithium reduces NP
  • No evidence serotonin is involved
sleep and circadian rhythms
Sleep and Circadian Rhythms
  • Bipolar patients show sensitivity to light
    • More suppression of melatonin when exposed to light at night
    • Regulates sleep
  • Insomnia can trigger manic episodes
stressful life events2
Stressful Life Events
  • Also strong relationship
    • Especially early mania
  • Can also prevent recovery
  • Upward spiral of positive events
  • Severe will trigger for 50%
  • Disrupted social interactions worst
social support1
Social Support
  • Speeds recovery from depressive, not manic, episodes
bipolar disorder in children1

why gender differences
Why Gender Differences?
  • College students - men/women who complete are more masculine
  • Women who survive an attempt = less stigma?
  • Men choose more fatal methods
risk factors
Risk Factors
  • Family history
    • 6x increase in offspring of attempters

misconceptions of suicide
Misconceptions of Suicide
  • People who talk about it are unlikely to commit it
    • OR People who do it don’t talk about it
  • People who commit suicide are irrational
