Q

relationship btwn child and adult psychopathology

A
  • some disorders are unique to children
    • eg: separation anxiety disorder
  • some disorders are primarily childhood disorders, but may continue into adulthood
    • eg: adhd
  • some disorders are present in children and adults
    • eg: depression

symptoms can be quite different in adulthood than in childhood

Q

the more prevalent childhood disorders are often divided into two domains:

A
  • Externalizing disorders (outward-directed behavior such as aggressive, noncompliant, over-active, impulsive)

Q

Etiology of CD- Genetic factors

A
  • Heritability likely plays a part
  • twin study mixed results
    • genetics played role in rule-breaking behavior in wealthy areas, not as much in poor areas
  • adoption studies focused on criminal behavior, not conduct disorder
  • meta-analysis of twin + adopt studies suggest 40-50% heritability of antisocial behavior
    • genetics stronger influence when behaviors begin in childhood (rather than adolescence)
  • genetics and environment-
    • abuse as child PLUS low MAOA activity most likely to develop CD

Q

Intellectual Disability- DSM-5

A
  • Intellectual deficit of 2 or more std deviation in IQ below the avg score for age + culture- typically below 70
  • sig deficits in adaptive func relative to age + culture in 1+ area:
    • communication
    • social participation
    • work or school
    • independence and home/community
    • requiring need for support at school/work/ind. life
  • onset during development
84
Q

Intellectual disability- Dsm-5 changes

A
  • explicit recog that IQ score consirdered w/in cultural context
  • adaptive func also assessed/ considered w/in age/culture
  • no longer distinguish mild, mod, severe ID based on IQ scores alone
85
Q

Etiology of Intellectual Disability- neurobiological factors

A
  • Down syndrome
    • chromosomal trisomy 21- extra copy of chromosome 21 ( 47 instead of 46)
  • Fragile-X syndrome
    • mutation in fMR1 gene on X chromosome
  • Recessive-gene disease
    • Phenylketonuria (PKU)
  • Maternal infectious disease, esp during 1st trimester
    • cytomegalovirus, toxoplasmosis, rubella, herpes simplex, HIV, syphilis
  • lead/mercury poisoning
86
Q

Treatment of Intellectual Disability- residential, behavioral

A
  • Residential treatment
    • small- med sized community residences
  • Behavioral treatments
    • language, social, motor skills training
    • method of successive approximation (shaping) to teach basic self-care skills for severe cases (holding a spoon, toilet)
    • applied behavioral analysis- applying behavioral learning theory to learn new skills
  • Cognitive treatments
    • problem-solving strategies
  • computer-assisted instruction
87
Q

Autism Spectrum Disorder- DSM-5 vs IV-TR

A
  • DSM-5 combines multiple diagnoses into Autism Spectrum disorder:
    • Autistic disorder
    • Aspergers Disorder
    • pervasive developmental disorder not otherwise specified
    • childhood disintegrative disorder
  • research didn’t support distinctive categories
  • share similar clinical features- vary only in severity
  • DSM_5 includes clinical specifiers relating to severity and extent of language impairment
88
Q

`DSM-5 criteria for Autism spectrum disorder

A

total of 6+ items from A, B, and C below w at least 2 from A, 1 each from B and C

A. Deficits in Social communication/interactions:

  • deficits in nonverbal behavior (eye contact, facial expression, body lang)
  • deficits in dev of peer relationships
  • deficits in social/emotional reciprocity (not approaching others, not having back-and-forth, reduced sharing of interests/emotions)

B. Restricted, repetitive behavior patterns/interests/activities

  • stereotyped or repetitive speech motor movements, use of objects
  • excessive adherence to routines, rituals in verbal/nonverbal behavior, resistance to change
  • v restricted interests abnormal in focus, such as parts of objects
  • hyper or hypo-reactivity to sensory input or unusual interest in sensory enviro

C. onset in early childhood
D. symptoms limit and impair functioning

89
Q

characteristics of autism

A
  • profound problems w social world
  • theory of mind
  • communication deficits
  • repetitive and ritualistic acts
90
Q

autism - profound problems w social world

A
  • rarely approached by others, may look through people
  • problems in joint attention
  • pay attention to different parts of face- neglect eye contact
  • this likely contributes to difficulties in perceiving emotion in other people
91
Q

autism- theory of mind

A

theory of mind

  • understanding that other people have different desires, beliefs, intentions, emotions
  • crucial for understanding and successfully engaging in social interaction
  • typically develops btwn 2.5-5 yrs
  • children w ASD seem not to achieve this developmental milestone- atleast to same degree
92
Q

autism-communication deficits

A
  • kids w ASD have evidence of early language disturbances
  • Echolalia: immediate or delayed repetition of what was heard
  • pronoun reversal
  • literal use of words
93
Q

ASD- repetitive and ritualistic acts

A
  • extremely upset when routine altered
  • engage in obsessional play
  • engage in ritualistic body movements
  • become attached to inanimate objects
94
Q

ASD- comorbidity, prevalence, prognosis

A

Comorbidity:

  • IQ> 70 common
    • kids w intellectual disability score poorly on all parts of IQ test, ASD score poorly on subtests related to language, tasks requiring abstract thought, symbolism, sequential logic
  • anxiety
  • specific learning disorder

prevalence

  • 1/110 kids
  • found in all SES, ethnic, racial groups
  • diagnosis of ASD remarkably stable

prognosis

  • kids w higher IQ who learn to speak b4 6 have best outcomes
95
Q

Etiology of ASD- genetic

A
  • heritability: .80
  • twin studies: 47-90% for MZ twins, 0-20% for DZ
  • genetic flaw- deletion of chromosome 16
96
Q

Etiology ASD- Neurobiological factors

A
  • Brain size
    • although normal size at birth, brains of autistic adults/kids are bigger than normal
    • pruning of neurons not occurring
      -“overgrown” areas include frontal, temporal, cerebellar - linked to language, social, emotional func.
      -abnormally sized amygdalae predicted more difficulty in social behavior/communication
97
Q

Treatment of ASD

A
  • Psych treatments more promising than drugs
  • Earlier treatment = better outcomes

Behavioral treatments:

  • Intensive Operant Conditioning (dramatic, encouraging results)
    • using reinforces to teach kids appropriate responses, motor behavior etc.
  • Parent training and education
  • Pivotal Response Treatment
    • focus on increasing motivation and responsiveness rather than on discrete behaviors
  • Joint Attention Intervention and symbolic play used to improve attention and expressive skills
98
Q

treatment for ASD- meds

A

Haloperidol (Haldol)
- antipsychotic
- reduces aggression and motor behavior
- doesn’t improve language and interpersonal relationships
