Final Exam Flashcards
(145 cards)
DSM classification broadly identifies mood disorders as either:
Unipolar: a single depressive mood experience
Bipolar: involves mania and depression
2 separate categories of mood disorders
Depressive disorders
Bipolar and related disorders
Major depressive disorder (MDD) is defined by the presence of: (8)
- one or more major depressive episodes or irritable mood episodes
- loss of pleasure (anhedonia)
- change in weight or appetite
- sleep problems
- fatigue or loss of energy
- feelings of worthlessness or guilt
- difficulty thinking or concentrating
- thoughts of death or suicidal thoughts and behaviour
DSM diagnostic criteria of MDD
- must have 6 out of 8 symptoms
- symptoms must be present for at least 3 consecutive days and must last for at least 2 weeks
- must cause individual clinically significant stress or impairment
Persistent depressive disorder (dysthymia) diagnostic criteria
- same symptoms of MDD but symptoms are less severe and more chronic
- symptoms must be present for at least 1 year
- must be clinically significant and cause distress or impaired functioning
- along with 2 or more of the following symptoms:
Poor appetite or overeating
Sleep disturbances
Low energy or fatigue
Low self esteem
Difficulty concentrating or making decisions
Feelings of hopelessness
When can MDD appear in children
Depression can start as early as preschool
What is the most prevalent form of affective disorder among children and adolescents?
Major depressive disorder (MDD)
Epidemiology of depression (clinical vs community)
-Clinical sample: rates in children range from 80% MDD
-Community sample: rates in children range from 0.4-2.5%
-Lifetime prevalence rates of diagnosable depressive disorders are 20-30%
-Typically occurs more in females than in males after the age of 12
SES, ethnic, and cultural considerations for depression
- research suggests that lower SES associated with higher rates of depression
- possible influences on income on MDD:
Chronic stress (on mood and physical symptoms of MDD)
Family disruption
Environmental adversities
Racial and ethnic discrimination
Biological influences on depression (genetics- family history of depression)
- highly heritable but not the only factor
- higher rates in first degree adult relatives
- genetic effects may influence personality and temperament
Biological influences of depression (neurochemistry and brain functioning)
- serotonin, norepinephrine, acetylcholine
- builds on research that finds certain classes of medication are effective as antidepressants
- low levels of serotonin and norepinephrine are results of too much reabsorption by the neuron and the breakdown of neurotransmitter too efficiently
Social-psychological influences on depression (2)
Separation and loss
- can produce adverse circumstances including lack of care, changing in family structure, socioeconomic problems
Cognitive and interpersonal perspective
- interpersonal skills, cognitive distortions, views of self, control beliefs, self regulation, and stress
- the way a person relates to others, is viewed by others, and view themselves contributes to how depression developed and/or is maintained
Impact of parental depression
Children from homes with a depressed parent are:
- greater risk of developing MDD and other disorders
- less likely to get treatment
Garber and Flynn (2001): longitudinal study of children with depressed mothers - findings
Possible that behaviour of depressed parents may be accompanied by anger, frustration, and hostility
- alters the parent’s ability to parent effectively
- parents may be detached, withdrawn, and inattentive
- depressed behaviour is maintained by parent-child interactions
Assessments of depression
Self report measures
- children’s depression index (CDI)
- revised children’s anxiety and depression scale
Parental/teacher measures
- behaviour assessment system for children (BASC)
Observations and clinical judgment
For children, might not use the DSM; would instead use evidence based on that particular child
Treatment of depression (medications and CBT)
Medications
- past: tricyclic antidepressants
- present: SSRIs and second-generation antidepressants
CBT and interpersonal psychotherapy
- challenge maladaptive thoughts and negative attributions, teach problem solving/coping skills
- understand interpersonal issues and problem solving
Bipolar disorder definition
Involves the presence of mania as well as depressive symptoms
Mania and euphoria definitions
Mania: period of abnormally elevated euphoric mood
Euphoria: characterized by inflated self esteem, high rates of activity, speech and thinking, distractibility, exaggerated feelings of physical and mental well being
DSM-5 criteria for manic episode
Persistent elevated, and expansive or irritable mood
3 of the following:
- inflated self esteem
- decreased need for sleep
- more talkative than usual
- thoughts racing
- distractibility
- psychomotor agitation
- excessive pleasure seeking
Types of bipolar disorder
Bipolar I: involves a history of MDD and mania
Bipolar II: involves a history of MDD and hypomania (euphoric mood that is shorter in duration - about 4 days - and less severe than manic episodes)
Cyclothymic disorder: chronic but less severe fluctuations in mood. Does not meet criteria for depression or BPD
Comorbidity of bipolar disorder and ADHD?
60%-90% of children
FIND (frequency, intensity, number, duration) criteria for BD (Kowatch et al. 2005)
-Exceedingly happy or silly (no apparent reason)
- Intense outbursts or anger/hostile
-Frequent irritable moods
-Less sleep than usual (full of energy)
-State of grandiose views of their abilities and plans
-Intense concentration on activity but becomes increasingly disorganized
-Rapid/unintelligible and difficult to follow speech
-Flight of ideas
-Poor judgement
Epidemiology of BD - Blader and Carlson (2007)
National representative sample (0-19yo) of doctor visits for mental health related issues = 6.67% in 2002-03
Between 1996-2004: children = 1.4 to 7.3 per 10000; teens = 5.1 to 20.4 per 10000
Prevalence of BD
0-6% in a community sample of children and adolescents
Distribution of males and females are equal
No significant cultural/ethnic differences
Less prevalent in prepubertal youth
