Ch. 13 Disorders of Childhood Flashcards
developmental psychopathology
study of childhood disorders within the context of lifespan development
externalizing disorder
outward-directed behaviors
- aggressiveness, noncompliance, overactivity, impulsivity
- ADHD, Conduct Disorder, Oppositional Defiant Disorder
- when does that cross the threshold of disproportionate?
hyperactive behaviors
- extreme for a particular developmental period
- persistent across many situations
- linked to significant impairments in functioning
- particular difficulty controlling activity in situations that require sitting still
what else could be going on in hyperactive situations?
- academic settings differ with ages/grades
- boredom
- sugar/preservatives
- frontal lobes: executive functions; plan, working memory
- dysregulated stress response: early brain learning is what expected
ADHD: difficulty getting along with peers
- aggressive, intrusive behaviors
- difficulty noticing subtle social cues; moving so quickly they never perceive it
- identified quickly and rejected/neglected by peers
DSM-5-TR criteria for ADHD
- symptoms of inattention and/or hyperactivity-impulsivity interfere with school, work, or relationships
- these symptoms and behaviors don’t fit with what
inattention
manifestations can include:
- making careless mistakes
- not listening well
- not following instructions
- being easily distracted
- being forgetful in daily activities
hyperactivity-impulsivity
manifestations can include:
- fidgeting
- non Stop talking
- interrupting or intruding
ADHD and comorbidities
- symptom onset before 12 years old
- two or more settings
- significant impairments in social, academic, or occupational functioning
- frequent peer rejection
- children: 6 symptoms of inattention and/or hyperactivity required
- 17 +: 5 symptoms required
three ADHD specifiers
- predominately inattentive presentation
- predominately hyperactive-impulsive presentation
- combined presentation (most cases)
ADHD & co-occuring disorders
- conduct disorder
- ADHD more associated with off-task behavior in school, cognitive achievement deficits, and better long-term prognosis
- anxiety and depression
- learning disorders
- substance use disorders
ADHD prevalence
- 8-12%
- dramatic rise in past decade
- public policy influences:
access to comprehensive diagnostic testing
education policies - 3X more common in boys
symptoms persist beyond childhood
girls with / without ADHD
- combined subtype more likely to have comorbid diagnosis of conduct or oppositional defiant disorder
- viewed more negatively by peers
- likely to have internalizing symptoms by early adulthood (anxiety and depression)
- exhibit neuropsychological deficits, particularly in executive functioning
- by adolescence, more likely to have symptoms of an eating disorder and substance abuse, have unplanned pregnancies, lower academic achievement, and more risky decisions
genetic etiology of ADHD
- adoption and twin studies: 70-80% heritability
- candidate genes
- GWAS studies
ADHD candidate genes
- dopamine genes (DRD4, DRD5, DAT1) increase risk when prenatal maternal nicotine or alcohol use are present
- SNAP-25 codes for protein that promotes plasticity
ADHD GWAS studies
- inconsistent with the implicated genes, and many genes are identified are not specific to ADHD
- domino effect with other genes
- these genes are not always the identifying factors in studies
- public facing
neurobiology etiology of ADHD
- differences in brain structure, function, and connectivity
- dopaminergic areas smaller in children
- perinatal and prenatal complications
- environmental toxins
dopaminergic areas smaller in children
- amygdala, hippocampus, caudate nucleus, nucleus, accumbens, putamen
- poor performances on tests of frontal lobes functions
perinatal and prenatal complications
low birth weight (but effects can be mitigated by maternal warmth)
environmental toxins
- food additives
- no evidence that refined sugar → symptoms
- maternal smoking
family influences of etiology ADHD
- parent-child relationships interacts with neurobiological influences
- parents give more commands and have more negative interactions
but children are often less compliant and more negative in interactions with their parents - many parents of children with ADHD have ADHD themselves
- contribute to maintaining or exacerbating ADHD symptoms
treatments of ADHD
- stimulants (Ritalin, Adderall, Concerta, Strattera)
- medical + behavioral treatment (MTA study
- psychological treatment
stimulants
- Ritalin, Adderall, Concerta, Strattera
- reduce disruptive behavior, aggression, and impulsivity
- improve ability to focus attention
- improve concentration, goal-directed activity, and classroom behavior
- improve social interactions with parents, teachers, and peers
- effective in about 75% of children with ADHD
medical + behavioral treatment
combined treatment slightly better than medication alone, and yields improved functioning (social skills)
psychological treatment
- behavior monitoring (daily report cards)
- reinforcement of appropriate behavior
ADHD focus of treatment
- improving academic work
- completing household tasks
- learning specific social skills
- do not specifically focus on reducing symptoms
treatment of conduct disorder
- most effective when it addresses multiple systems involved in the life of a child
- Multisystemic Treatment (MST)
- each area of influence (genetic, neurobiological, and psychological)
Multisystemic Treatment (MST)
family, peers, school, neighborhood, culture, genetic makeup, history (everything up until point of assessment), stress & self control
conduct related disorders
- Intermittent explosive disorder (IED)
- Oppositional defiant disorder (ODD)
Intermittent explosive disorder (IED)
- recurrent verbal or physical aggressive outbursts that are out of proportion to the circumstances
- aggression is impulsive (not pre-planned)
Oppositional defiant disorder (ODD)
- loses temper, argumentative, lack of compliance, deliberately aggravates others, vindictive, spiteful, touchy
- could be abused to changes in development that occurs with adolescents and teens
- moves across situations in similar ways
- what leads to the outburst is more important than the outburst itself
- often comorbid with ADHD, but disruptive behavior is more deliberate than is the case for ADHD
conduct disorder
- defined by the impact of a child’s behavior on people and surroundings
- aggressive behavior: physical cruelty, serious role violations, property destruction, deceitfulness
- severity and frequency
- diagnostics specifier: “limited prosocial emotions”
limited prosocial emotions
- callous and unemotional traits: lack of remorse, empathy guilt, shallow emotions
- more severe course, cognitive deficits (pattern recognition), antisocial behavior (peer rejection & leaving people out of social groups), and poorer remorse to treatment
- do not respond well to treatment
DSM-5-TR criteria for conduct disorder
- pattern of repeated, destructive, and harmful behavior
aggression
property destruction
lying/stealing
breaking rules - different levels of parental observation
- will pursue risky behaviors when left to their own devices
- approach situations differently depending on their history
longitudinal course of CD
- significant impairment in social, academic / occupational functioning
- substance abuse is common
- relationship is to impairment is bidirectional
comorbid related disorders with CD
- anxiety and depression (15-45%)
CD precedes depression as well as most anxiety disorders
CD comes first - 7% preschool children exhibit symptoms of CD; early assessment is critical so their neurobiology can be redirected
Two Courses of CD (Moffitt, 1993)
- life-course-persistent
- adolescence-limited
