Autism Flashcards
Autism defined:
Generally evident when?
- Before 3yrs of age
Autism defined:
- Developmental disability sig. affecting verbal and non-verbal communication and social interaction, generally evident <3yrs of age, that adversely affects childs educational performance
Other Characteristics assocd w/ autism:
3:
- Repetitive activities and stereotyped mvmts
- Resistance to environ. change OR change in daily routines
- Unusual responses to sensory exp’s
Autism Spectrum Disorder “ASD”
Defined:
- Term used to indicate behavior cond’s that exist on a continuum
- Mildly→ severely involved
- Social communication, social interaction, sensory integration are affected
3 areas affected w/ ASD:
- Social communication
- Social interaction
- Sensory integration
Genetic link found w/ ASD when?
1980s
ASD
Prevalence
*most important
- FASTEST GROWING DEV. DISORDER
- 1 in 44 children ID w/ ASD
- Parents who have child w/ ASD have 2-18% chance having second affected
- 10% ASD also IDd w/ DS, Fragile X, tuberous sclerosis, genetic/chromosomal disorders
- 5x more common in bots
ASD
Prevalence
*Fastest growing develop. disorder
Contributing factors:
- More likely to properly ID autistic vs intellec. disabled
- Incd awareness/funding
- More broad DX
- Earlier diagnosis
ASD
Etiology
- NO known single cause
- Gen accepted→ abnorms in brain structure/function
ASD Risk Factors
Prenatal
- Gene mutations, environ factors, adv. age either parent
- DM, psychiatric drugs in mother
- Infections→ rubella, CMV
- Teratogenic causes
- Prenatal stress
ASD Risk Factors
Perinatal
- LBW
- Hypoxi
- Prematurity
Dx of ASD
Physicians use what?
Diagnostic and Statistical Manual (DSM) of Mental Disorders to det. whether person has ASD (DSM-5)
Dx of ASD according to DSM-5
- Dx called ASD
- No more sub-diagnoses
- New dx criteria arranged: 2 areas→
- Social communication/interaction**
- Restricted and repetitive behaviors**
2 areas of diagnostic criteria for ASD
- Social comm./interaction
- Restricted and repetitive behaviors
Clinically Diagnosing ASD
All following sx’s describing persistent deficits in social comm/interaction not acctd for by gen develop. delays, must be met:
MUST HAVE ALL OF THESE!!!
All of these are related to first area: Social communication/interaction
- Problems reciprocating emotions or social interaction
- Severe probs maintaining relationships
- Verbal/non-verbal communication probs
Clinically Diagnosing ASD
Two of the four sx’s related to restricted and repetitive behavior need to be present:
All of these are related to second area: Restricted and repetitive behavior
- Stereotyped or repetitive speech, motor mvmts or use of obj’s
- Excess adherence to routines, ritualized patterns of verbal or nonverbal behavior, OR excessive resistance to change
- Highly restricted interests that are abnorm in intensity or focus
- Hyper or hypo reactivity to sensory input or unusual interest in sensory aspects of the environ.
- not understanding environ.
- sensory feedback not working properly
Social Communication/Interaction Criteria
1.Problems reciprocating emotions or social interaction
Ex’s
- diff holding conversations
- unable to initiate interaction
- probs w/ shared attn or sharing emos/interests
Social Communication/Interaction Criteria
2.Severe probs maint. relationships
Ex’s
- lack interest in people
- diff. w/ pretend
- diff w/ age-approp social acts
- probs adjust to diff social expects
Social Communication/Interaction Criteria
3.Verbal/Non-verbal communication probs
Ex’s
- Abnormal eye contact, posture, facial express’s, tone of voice/gestures
ASD
Early warning signs
Lack eye contact, no resp to name, no interest in people, prefer not to be held*
ASD
More early warning signs:
- Trouble adapt to changes, unusual rxns smell, sound, taste, feel
- Unusual/repetitive way play w/ toys
ASD
More early warning signs w/ ages considered:
- No babbling or gesturing by 12 mos
- Inability to speak 1 word by 12-14mos
- Regression in OR loss of lang or social skills********* BIG ONE!!!!
ASD Early Warning Signs
Studies show…
- Parents notice dev. prob before 1st bday
- Vison/hearing concerns more often reported 1st year
- Diffs in Social, comm, fine motor skills evident from 6mos
Assoc’d Clinical Impairments:
BSF
- Failure of lang/comm. dev., sensory processing, sensory abnorms-sensitivity
- motor function, apraxia (motor planning)
- control of voluntary mvmts→ clumsy/uncoord
- restrictive repetitive behaviors
Assocd Clinical Impairs:
BSF cont’d
- over-rxns, intellectual impairs, poor eye contact, eating disorders, sleep, SZ’s, GI impairs
Assocd Activity Limits/Participation Restricts:
- Limtd gross motor skills, dec IND/safety, decd understanding rules,
- Decd efficiency w/ functional mob, assist reqd to sit/attend school t/o day, diff w/ interpersonal relationships/social relationships
ASD video
slide 32*****
PTs play a role for children w/ ASD MOST OFTEN in regards to:
BSF issues that reduce safety during activity or dec participation
PTs play a role for ASD MOST often in regards to BSF issues that reduce safety during activity OR dec participation
SUCH AS:
- Abnorm mm tone→ hypOtonia
- Apraxia/motor planning
- Gait impairs→ toe walking*** (very prevalent)
- Balance defs
- Gross motor delay
- Atyp. motor performance→ motor imitation/coord
- Sensorimotor integration
PT Exam for ASD
Hx → Important things to include:
- Social interactions/activities, support system, dev. hx, phys/psycho/social function,
- Behavioral habits, medical hx, chief complaints (family perceptions), functional status, meds
PT Exam for ASD
Systems Review
- CV/Pulm→ BP, edema, HR, RR
- Integ→ scarring, skin integ, coloring
- MSK→ ROM, strength, symmetry, ht/wt
- **NMSK→ Gross coord’d mvmts—- KNOW THIS ONE!
MOST COMMON MOTOR SX IN ASD
LOW MM TONE (HYPOTONIA)
51%
PT Exam for ASD
HypOtonia → MOST COMMON motor sx
- LOW mm tone
- Most common→ 51%
-
Improves over time w/ incd strength about jts
- wont change it, but can improve thru strength
