week 6 Flashcards
what is autism spectrum disorder
- A group of neurodevelopmental disorders that share common symptoms and functioning across social, cognitive, emotional and language domains.
diagnosis of autism
- Relies on observation of the child’s behaviours
- Checklist and testing of development with diagnostic criteria
- Gathers information from family, child care, other professionals and observations
- *no blood test to confirm
- *no single defining symptom
- *no physical characteristics that are unique.
what’s DSM-C criteria for ASD
A. Persistent deficits in social communication
- Deficits in social emotional reciprocity
- Deficits in non-verbal communicative behaviours
- Deficits in developing, maintain and understanding relationships
B. Restricted repetitive patterns of behaviours, interests or activities
- Stereotyped or repetitive motor movement, use of objects or speech
- Insistence on sameness
- Highly restricted, fixated interests that are abnormal in intensity of focus
- Hyper or hypo reactivity to sensory input or unusual interest in sensory aspect of the environment
- Eg having to lay out toys in a specific way
C. Symptoms must be present in early childhood but may be masked
- May not fully manifest until later when social demands exceed the limited capacities
D. Symptoms together limit and impair daily functioning
- Difficulties in the following are usually seen in the first two years:
- Social interaction
- Non verbal communication
- Relationships and play
- Restricted interests
- Routines
- Repetitive movements
- Sensory sensitivities
other features of autism but not part of diagnostic criteria
- Gross and fine motor skills
- Sleep
- Sensory processing
- Diet fussy eater
- Organisational skills
causes of autism
genetics:
- Not fully identified ye
- May be 3-10 genes that are interacting
- Mode of ineritance is not known
- Siblings have igher risk of ASDNeuro development disorder:
- Cortex: exectuvie functions, movement perception, behvaiours
- Basal ganglia: regulate automatic movememtns
- Cerebellum: fine tubes movements, regulates balance and coordination
- Amygdala: emotional repsonses
comobilities of autism
- Intellectual disability (70%) speech and language disroerds - Anxiety - Depression - Epilepsy - Asthma and allergies - Attention disorders - Developmental coordination disorder - Down syndrome
boys vs girls ratio of autism
Ratio of boys to girls 4:1
what is sensory processing
The ability to process sensory information in the Central Nervous System (CNS) for adaptive behaviours
Includes:
Reception, Modulation, Integration and Organisation
what areas of the brain does sensory processing involve
Frontal lobe: reasoning, emotions, judgemtn and voluntarymovement
Temporal lobe: hearing and memory
Occipital lobe: vision and reading abilty
Parietal lobe: sensory integration centers
whats the purpose of sensory process development
- Children learn about their environment through integrated sensory systems eg visual, auditory
- Children learn about their bodies through integrates sensory systems eg tactile, vestibular
whats the standard process of sensory processing
Aquire sensory information
Process the information
Resond to the information
Feedback on how the information was
whats sensory integrations
the biran can relate all sensory inputs into a coherent percept upon which our interaction with the environment is ultimately based
whats the sesnsory threshold
- The level at which one detects and responds to sensory information
what happens if you are below the sensory threshold
= unaware of sensory input therefore no response
what can the sensory threshold be affected by
- Accumulation of sensory over time
- The sensory system is being activated
- Intensity
- Location of input (where is it coming from)
- Anxiety levels
whats responsively
the range within which sensory input is tolerated and used
whats a wider range of tolerance=
more likely the child maintains regulated and adaptive behaviour
whats narrow range of tolerance =
likely to have limited range of behaviours and only bale to perform in a limited number of sensory environments. Eg only able to write story in quiet and calm controlled environment
if the threshold is high
lots of sensory input needed to meet sensory needs
whats the two types of high thresholds (Dunns model)
active high threshold child
passive high threshold chidl
whats an active high threshold child (duns model)
Active attempt to meet for high levels of sensory input
