no medical test - diagnosis based on observation of the individual’s communication, behavior, and developmental levels (autism diagnostic interview, home/school observation, video analysis, genetic studies 15-20 genes)
what is the most effective method of acquiring new behavior in autistic children
discrete trial instruction aka “applied behavior analysis”
what is the most effective method of decreasing problematic behavior in autistic children?
reinforcement-based treatments
which meds are commonly prescribed for assoc. behaviors in autism?
antipsychotic meds and stimulants (MC)
what are the three criteria for diagnosis of intellectual disability?
- subaverage intellectual functioning (IQ less than 70)
- deficits in adaptive functioning (2+: communication, self-care, social skills, self-directions, academics, work, safety, etc)
- onset before 18
mild ID criteria/lifestyle
IQ 50-70 (90% of ID)
similar to non-ID kids for 1st few years of life, achieve about 6th grade academic level
can support self with minimal supervision
moderate ID
IQ 30-50 (10%)
academic skills up to 2nd grade - benefit from extensive social and vocational training
-can perform unskilled or semi-skilled tasks under supervision
severe ID
IQ 20-35ish (3.5%)
-can acquire some basic self-help skills
can learn to count or “read”
-require assistance for most activities/daily life
profound ID
IQ less than 20-25
- may have difficulty with simple tasks even with supervision
- function best in highly structured settings
ID more common in…
males
causes of ID
unknown 30-40% of cases
- 30% chromosome abnormaliy
- 15-20% environment or other mental disorders
- 10% problems in pregnancy
- 5% hereditary (fragile X)
- 5% other medical condition (lead poisoning)
challenging behavior in autism
repetitive behaviors are considered an “essential” feature of autism (flapping)
some display challenging behavior considered “associated” including self-injury, aggression, property destruction, pica, etc
