Week 10 Flashcards
Depressive states vs. Depressive Disorders
Depressive states:
Feeling in low spirits, “sad”, “down”, “feeling blue”
Appropriate response to loss or other painful life events
May feel tired, irritable, and have changes to sleep, eating, and concentration
Depressive disorder:
Significant distress and/or interference with functioning
Emotion vs Mood vs Affect
Emotions:
shorter term response that is evaluative in nature
and involves physiological arousal, subjective experience,
and behaviours
Mood:
pervasive and sustained emotions
Affect:
observed by others (remarkable affect would be quite noticeable)
Depressive Disorders in Children
In decades past, depression in children was not recognised
Previously, children were described as showing other behaviours in response to traumatic losses, e.g.,
rebelliousness, restlessness, and somatic symptoms (“masked depression”)
Now widely recognised that children can exhibit same
characteristics of depression as adults
Behaviour problems can accompany depression (rather than masking it)
MDD and Persistent Depressive Disorder: Common Features
Depressed mood (or irritability in children)
Accompanying symptoms:
Changes in appetite and/or eating behaviour
Changes in sleep
Changes in energy level
Low self-esteem (PDD)
Poor concentration, indecisiveness
Feelings of hopelessness (PDD)
Diminished interest or pleasure (MDD)
Worthlessness, guilt (MDD)
Recurrent thoughts of death or suicide (MDD)
Clinically significant distress and/or impairment in social, occupational or other important areas of functioning
Differential diagnosis: the basics
Major Depressive Disorder:
5 or more symptoms in 2 week period
Persistent Depressive Disorder: persists for at least one
year in children (2 years in adults); can have periods of MDD (“double depression”)
Bipolar disorder:
presence of manic or hypomanic episodes
Adjustment Disorder with Depressed Mood:
essential feature is reaction to a recent identified stressor
Disruptive Mood Dysregulation Disorder (DMDD):
New category for children under 12
Chronic, severe, persistent irritability, which may take the form of aggressive outbursts or angry mood
Aggressive outbursts or angry mood not limited to discrete episodes (as in Bipolar Disorder)
Inconsistent with child’s developmental level
Lasts for at least 12 months
MDD Point prevalence
1-2% pre-schoolers
1-3% school-age children
5-6% adolescents
MDD Lifetime prevalence
15-20% adolescents
Course and gender differences
Marked increase in prevalence at adolescence
Females»_space; Males
Prevalence: Other Depressive Disorders
Important point: Less research for these categories Disruptive Mood Dysregulation Disorder Estimated at 2-5% in youth Expected to be more common in children compared to adolescents More common in boys than girls
Persistent Depressive Disorder
Not as common as MDD
Gender disparity seen in MDD not seen in PDD
Aboriginal and Torres Strait Islander people:
Aboriginal and Torres Strait Islander people are nearly twice as likely to die by suicide.
Indigenous Australians are nearly three times more likely to be psychologically distressed than non-Indigenous Australians.
Racism, both perceived and actual experiences, is increasing which affects wellbeing
Dramatic increase in adolescence, esp. for girls
Proposed explanations
Gender-specific life stressors
Early developing girls exposed to interpersonal stressors, sexual harassment
Onset of puberty
Girls more likely to see changes of adolescence as negative
Girls may more sensitive to peer pressure
Girls may more sensitive to interpersonal stressors in family
Also limited opportunities for girls compared to boys?
Depressive Disorders in Children: Comorbidity
Commonly comorbid with anxiety
Also comorbid with CD, eating disorders, substance abuse
Associated problems
suicide (can be suicidal without depression)
Recovery and Recurrence
High rates of recovery paired with high rates of recurrence
