Flashcards in Mood Disorders Deck (56):
What are moods?
Pervasive and sustained
Influence our perception of the world
Occurs in a person for a length of time
Not as intense as affect
How are mood disorders characterized?
On a continuum
How is major depressive disorder diagnosed based on the DSM-5?
Presence of 5 or more symptoms for at least 2 weeks
Note: Depressed mood or loss of interest and pleasure must be 1 of the 5 symptoms
What are the symptoms of depression?
Sad, depressed mood, most of the day, nearly every day
Loss of interest and pleasure in usual activities (ex. sex)
Difficulties in sleeping
Shift in activity level
Changes in appetite and weight
Loss of energy, great fatigue
Feeling worthless/excessive guilt
Difficulty in concentrating
Recurrent thoughts of death or suicide
Somatic symptoms with no apparent physical basis
Negative self-concept, self-reproach and self-blame
What are the specifiers for major depressive disorder?
Seasonal pattern (Seasonal Affective Disorder)
With postpartum onset
What are the characteristics of melancholic features?
Pervasive anhedonia (no joy)
Don’t feel better even when pleasant or good things happen
Significant appetite and weight loss
Depression worse in the morning
Early morning awakenings
Psychomotor retardation or agitation
Inappropriate or excessive guilt
What are the characteristics of atypical features?
Mood reactivity – positive events
Weight gain or increased appetite
Physically burdened - paralysis
Sensitivity to interpersonal rejection
What are the characteristics of psychotic features?
Delusions (false beliefs)
Hallucinations (false sensory perceptions)
Mood congruent (e.g., internal organs rotten)
More likely to suffer from melancholia
What are the characteristics of catatonic features?
Motoric immobility or purposeless movement
Echolalia (repeat what they hear)
Posturing – sit hunched, away from world, sometimes bizarre statue like poses
What are the characteristics of Seasonal Affective Disorder (SAD)?
MDD with seasonal pattern
At least 2 MDEs in past 2 yrs occurring at the same time of the year (mostly winter)
No non-seasonal episode in past 2 years
More seasonal than non-seasonal lifetime episodes
What are the characteristics of Postpartum depression?
MDE with postpartum onset
Onset of MDE within 4 wks after childbirth
Impact of maternal depression on children
Different from “postpartum blues”:
mother is emotionally labile, irritable, but does not meet criteria for MDD
occurs in 50-70% of new mothers (not MDD)
What are the characteristics of Dysthymic Disorder?
Low grade depression
Depressed mood most of the day, more days than not, for at least 2 years. Never without symptoms more than 2 months at a time.
No Major Depressive Episode during the first 2 years
Significant distress or impaired functioning
Not due to substance or general medical condition
Two (or more) of the following:
Low energy or fatigue
Feelings of hopelessness
What is double depression?
When a MDE occurs on top of dysthymia
What is the danger with the reoccurence of depression?
Each MDE increases the risk of a subsequent episode. After:
1 episode – 50-60% will have another
2 episodes – 70% will have another
3 episodes – 90% will have another
With each subsequent MDE, the length of time to recurrence is shortened
What is the diathesis stress model for depression?
Depressive episodes often follow stressful life events
Not everyone becomes depressed following stressful life events.
Some are possibly biologically predisposed
What is the cognitive model for depression?
Cognitive diathesis: latent dysfunctional cognitive patterns (e.g., self-schemas)
Models differ in how the cognitive diathesis is conceptualized
Stress: broadly defined – severe life events, sad mood
Cognitive models of vulnerability to depression.
Beck’s negative triad
Response styles theory
What is Beck's theory of depression?
Negative triad: Self, World, Future
Negative schemata develop in childhood
Information-processing, Memory and Attentional biases:
Depression is not associated with greater initial orientation toward negative stimuli
Depression is associated with difficulties in disengaging attention from negative material: Inhibitory dysfunction
Inhibitory dysfunction linked to rumination.
What is the response styles theory of depression?
The way a person responds to a negative mood can have an impact on the severity and/or duration of depression symptoms.
Passively focusing one's attention on a negative emotional state, and thinking repetitively about the causes, meanings and consequences of that state.
Depressed individuals tend to ruminate more than non-depressed individuals when in a negative mood.
What is the hopelessness theory of depression? (Based on Seligman’s theory of learned helplessness)
An individual's passivity and sense of being unable to act and control his or her own life is acquired though unpleasant experiences and traumas that the individual tried unsuccessfully to control.
Depressogenic attributional style: negative events due to causes that are:
Internal – “It’s all my fault”
Stable – “I’ll always be this way”
Global – “I’m a total loser”
Now thought to explain only “hopelessness depression”
Depressive paradox: Feeling helpless yet blaming oneself
Depressive predictive certainty: Perceived probability of the future occurrence of negative events becomes certain
What are the biological theory for depression?
Potential gene candidate: promoter of the serotonin transporter gene (5-HTT)
Lowered sensitivity of serotonine receptors makes some individuals more vulnerable to depression.
What is the Monamine theory of depression?
Depression once thought to be caused by low levels of:
Not supported by empirical research: more complex.
What clues for theories of depression are based on drug effectiveness ?
Tricyclic drugs prevent some of the reuptake of norepinephrine, serotonin, and/or dopamine by the presynaptic neuron after it has fired.
Monoamine oxidase (MAO) inhibitors keep the enzyme monoamine oxidase from deactivating neurotransmitters therefore increase the levels of serotonin, norepinephrine, and/or dopamine in the synapse.
Selective serotonin reuptake inhibitors inhibit the reuptake of serotonin
What medications are used to treat depression? What are some considerations clinicians should take into account?
Monoamine Oxidase Inhibitors (MAOIs)
Selective Serotonin Reuptake Inhibitors
Delay in effect of medications
Relapse and recurrence
Both MAOIs and Tricyclics take 7-14 days to relieve depression, but by that time, the NT levels have already returned to their previous state
What are other examples of biological therapy for depression?
Electroconvulsive Therapy (ECT)
Transcranial magnetic stimulation (TMS) over left prefrontal regions
High relapse rate
What are the psychological therapies for depression?
Cognitive and Behaviour Therapies
Mindfulness-Based Cognitive Therapy
What does CBT consist of?
Person’s affect and behavior are largely determined by the way in which they view the world.
Cognitions can be assessed and changed.
Modification of cognitions will lead to changes in affect and behavior
Aimed at altering maladaptive thought patterns
Change opinions of events and self
What are some examples of cognitive errors?
Overgeneralization: Arbitrary inference
Depressed persons draw negative conclusions about their self-worth, based on minimal data
Depressed person focuses on isolated negative details of an event and ignores more positive information
Everything is good or bad
Magnification and Minimization:
Exaggerations in evaluating performance
What are the steps of CBT?
Step 1: Recognize and record automatic thoughts
Daily monitoring of thoughts, situations, emotions
Step 2: Logical analysis of automatic thoughts
Is there any evidence that supports the thought?
Is there any evidence that goes against it?
If the negative thought is accurate, what can be done to best cope with it?
Step 3: Generate alternative, rational thoughts
What is another way to think about situation?
Step 4: Practice alternative thoughts
What is a manic episode?
An emotional state of intense but unfounded emotions accompanied by elevated, expansive or irritable mood
At least 3 of the following: Hyperactivity
Inflated self-esteem or grandiosity
Decreased need for sleep
Pressured speech (talkativeness)
Racing thoughts (flight of ideas)
Increase in goal-directed activities (impractical grandiose plans)
Excessive risky or pleasurable activities
Symptoms last for at least 1 week
Severe enough to cause significant impairment in functioning or hospitalization or there are psychotic features.
What is a mixed episode?
Meets criteria for MDE and Mania for at least 1 week nearly every day
What are the features of Bipolar I?
One or more Manic or Mixed Episode(s)
Symptoms are not better accounted for by a psychotic disorder
History of MDE is NOT required for diagnosis
Requires the presence of elevated or irritable mood and abnormally and persistently increased goal-directed activity +3 additional manic symptoms.
What are the features of Bipolar II?
One or more MDE
One or more Hypomanic episode
NO history of Manic or Mixed episode
Symptoms are not better accounted for by a psychotic disorder
Psychotic and melancholic features
What are the features of Cyclothymic Disorder?
Numerous periods of hypomanic symptoms and numerous periods of depressive symptoms.
Duration of at least 2 years
No Manic, Mixed or Depressive Episodes in first 2 years
Never symptom-free for more than 2 months
Distress but no severe impairment
What are biological theories of Mood disorders?
Heritability - Genetic vulnerability
(Twin, family and adoption studies, linkage analysis)
Bipolar I the most heritable disorder
Stress Reactivity (HPA axis) - Overactive - elevated levels of cortisol in both types of mood episodes.
Bipolar caused by overly sensitive dopamine receptors
Depression caused by amygdala hyperactivity (hippocampus, prefrontal cortex and anterior cingulate)
What are the treatments for Bipolar Disorder?
Medication - high relapse and side effects, low adherence rate. Stopping can be dangerous (dangerous, even fatal, calcium levels need to be monitored). Cuts highs and lows
Lithium: 70% response rate
Anticonvulsants: 50-60% response rate
Antipsychotics: faster onset
Lithium: effects not as robust
Mood switching risk
Lithium: 50% relapse if discontinue
Improved medication adherence
Fewer episodes; lower relapse rates
Decrease in residual symptoms
What are the Areas of Focus for Adjunct Psychotherapy?
Early Detection and Intervention
Stress and Life Management
Treat comorbid problems
Treatment of depression

Marital status: Divorced, separated, widowed
Prior attempts – best predictor
Psychiatric history, substance use
Experience of lack of control in maladaptive family
Limited problem-solving ability
Hopelessness, perfectionism and self criticism
Severity of suicide ideation
What are some possible causal factors of suicide?
Genetic factors may play a role in risk for suicide
Reduced serotonergic activity appears to be associated with increased risk
Rates of suicide vary across cultures and religions
What is Suicidal Ambivalence?
Some people do not really wish to die but instead want to communicate a dramatic message concerning their distress
Research has clearly disproved the tragic belief that those who threaten to take their lives seldom do so
What characterizes Hypomania?
Symptoms last for at least 4 days
Change in functioning
Change in mood and functioning is observable by others.
Same symptoms as mania but they are not severe enough to cause significant impairment in functioning or hospitalization and there are NO psychotic features.
What is the psychoanalytic theory of mood disorders?
Stuck in the oral stage because of over/under gratification in childhood causing a fixation. The person is excessively dependent on other for maintenance of self-esteem. Analysis of bereavement - loss of a loved one, identify with them, they become an object of hate and guilt that get directed inwards.
What does the Dysfunctional Attitudes Scale (DAS) measure?
Attitudes that bias interpretation of events:
1) Dysfunctional beliefs reflective the need for approval
2) Dysfunctional beliefs reflecting the need for achievement and perfection
What is the interpersonal theory of depression?
Behavioural aspects - sparse social networks, regard them as providing little support - vulnerability
Elicit negative reactions from others including rejection
Tend to reject their partners and display few positive social behaviours
Low social skills ex. speech patterns and eye contact
Constant reassurance seeking - temporarily satisfied
Seek out negative feedback to validate self-image - inconsistent
What are the psychodynamic therapies for mood disorders?
Encourages outward release of the hostility
Interpersonal therapy (IT): Concentrates of the present-day interactions between the depressed person and the social environment. Good for preventing relapse.
What is involved in Mindfulness-based CT? (MBCT)
Teaches how to combat stress through mindful meditation
Relaxation techniques designed to increase awareness of changes in the body and mind - cognitive intervention techniques

Modifiable treatment process for major depressive disorder in adults in outpatient settings "whatever works"
What is the treatment for SAD?
Bright white light phototherapy
More effective if combined with CBT
Counteract negative thoughts
Encourage engagement in everyday pleasurable activities
Social skills training
What are Durkheim's sociological theories of suicide?
Egotistic suicide: committed by people who have few ties to family, society or community. These people feel alienated from others and cut off from the social supports that are important to keep them functioning adaptively as social beings.
Altruistic Suicide: is viewed as a response to societal demands. Some people who commit suicide feel very much a part of a group and sacrifice themselves for what they take to be the good of society.
Anomic suicide: May be triggered by a sudden change in a person's relationship to society (lifestyle)
Realistic suicide: Euphanasia
Inadvertent suicide: Suicidal guesture to manipulate someone else but then accidently kill themselves
Spite: Intends to kill themselves to hurt someone else
Bizarre: Comits suicide because of a hallucination or delusion ex. command hallucinations
