D development I individual R relationship
Floor time treatment
Insights: Language develops thru comfortable interaction, motor sensory processing differs btw kids, new roadmap: 6 levels
Critical features of interaction
Warmth security engaged pleasurable reciprocal emotionally meaningful
Autism history
Leo kanner 1943
Hans asperger 1944
PDD
autism, Asperger, Rhett, Childhood disintegrative disorder
Ranges mild to severe,
Disinterest in social, impaired communication, narrow interests
Savant?
ONSET before 3
Difficulty w self regulation, motor planning
Uneven learning profile
Visual stronger than aud
Social interaction deficits (must have 2 to qualify)
Deficits in nonverbal
No relationships w peers
No joint reference (seeking to share enjoyment interests or achievements)
Communication deficits (at least one)
No or little development of oral language
Stereotypical repetitive or idiosyncratic (echolalic)
No typical symbolic play
Repetitive behaviors, narrow interests (exhibit one)
Intense preoccupation
Rigid adherence to nonfunctional routines
Motor behaviors that are stereotypical repetitive
Echolalic
Immediate Delayed Mitigated Unmitigated Communicative Non communicative
Autism sensory characteristics
Over or under reaction
Auditions- hyper or non response
Tactile- dislike light touch but firm ok, unusual reaction to pain, love tickling?
Rigidity
Disruption of routine leads to temper tantrum
Ritualistic behavior
Play same scenario
Have same convo
Autism comorbidity
25% develop seizures
2-5% fragile X
1-4% tuberous sclerosis
Asperger syndrome
Mildest form of autism? Most distinctive feature is severe social impairment Speech language not as severe IQ above 70, not DD HAS?
Rhett’s syndrome
Often misdiagnosed autism
Mutation chromosome 28
Neurological disorder almost exclusively affecting females
Normal develop up to 18 mos
Then lose purposeful movt- stimming like hand wringing
Head growth decelerates, gait falters, language disappears
Limited social interaction
Over time looks less like autism and more physical
Childhood disintegrative disorder
Normal devt two years followed by loss of social, self help, motor, language skills
hard to separate from autism bc parents of ASD often report normal devt for first bit
PDD NOS
Heterogeneous group
Too young to fit in a specific categ OR not severe enough symptoms
Prevalence
Before 1985: 4-5 per 10000, 2 classic autism
1993- 16 per ten thou
Late 90s to 2000: 17-40 classic, up to 67 on spectrum
2004: 71
Increase could be due to underreporting before, recent broadening of category
Autism: psychoanalytic theory
Ice box mother- lack of bonding in infancy,
complete lack of controlled evidence yet idea persists
Physical causes: theories
MMR vaccine- administer in developed countries around the same time autism is diagnosed
Mercury based Preservative thimersol blamed
EVIDENCE disproved
Pseudoscience therapy
Auditory integration therapy: controlled studies show no benefit
Sensory integration therapy: no evidence of efficacy specific to SIT
Vitamins, diet, Candida albicans: no controlled studies support
Chelation therapy: IV infusion of chelating agents to inactivate heavy metals, maybe appropriate for lead poisoning, adverse side effects? Advertised Worse before better
Autism: EB theories
Genetic & brain abnormalities
Male:female 3:1 X linked? Rate of autism in siblings 2-8% Monozygotic twins: 60-90% Dizygotic: 10% OCD, comm disorders, phobias in family members NO identified specific genes
Autism: brain abnormality
Autopsy, MRI studies Brainstem, limbic, cerebellum abnormality Patterns if head growth: Smaller head circumference at birth Abn rapid increase at a few months old Slows mid to late childhood Evens out late adolescence What does it mean?
