Sensory processing abnormalities (SPA):

Challenges in the diagnosis & assessment of children referred for possible social & communication disorders

3


Introduction

•SPAs – what are they▫ Abnormalities in the neurological processing or interpreting of

sensory stimuli

▫ Visual, auditory, fine touch, proprio-reception, smell, taste, pain

•How common are they in ASD▫ Most recent work suggests that at least 80% (and perhaps all)

children on the spectrum will have SPAs

▫ Large and growing academic literature

• This talk▫ A personal view and personal approach to the challenge of SPAs in

autism assessment based on 15 years experience and a lot of thinking


4

Various scenariosa) Children with SPA (with or without other co-morbidity)

who do not have ASD

b) Children whose SPA has shifted them, functionally, along the ASD spectrum (normal to pathological, mild to severe)

c) Children with both conditions in which teasing out which particular neuro-pathology accounts for which symptoms can be challenging

d) Children with multiple co-morbidities

e) Demand avoidance – pathological or adaptive?


5

Children with SPA without ASD.

Have adaptive behaviours which can appear:

▫Odd and socially inappropriate Hypersensitivity e.g.

to smell – either extreme avoidance (crisps and school dinners) or explore the world through smell (ooh your pen has been next to the chewing gum)

to textures - clothes

▫Socially avoidant and withdrawn hoodies, baseball caps, socks on hands, poor eye contact -

all as a result of sensory defensive strategies


6

Children with SPA without ASD - Cont:

Have adaptive behaviours which can appear: ▫Averse to affection

- abnormal seeking of comfort▫Egocentric

exaggerated personal space (won’t share sofa)

▫Repetitive seeking proprio-receptive feedback


7

Case 1: Girl 12 years

•LDs▫co-morbid anxiety disorder and OCD (very strong FH

of both with several family members diagnosed)

• Inappropriate school placement▫Quiet (almost elective mute) and still at school▫Aggressive and unmanageable at home

•Very poor proprio-receptive feedback▫Bizarre arriving home from school “ritual”

SPA shifting children along the spectrum


Autism Autism Cusp Traits “normal”(severe) (mild)

SPA Anxiety

Low mood

Case 2: Boy 14 years▫ Isolated, but severe and missed, SPA

Autism diagnosed aged 12 on very high ADOS score

▫Symptoms misunderstood by school and family Avoidance of physical contact, including as a baby Hidden friends and social network & hidden humour “this computer is mine” – seen as repetitive behaviour Shaved head every 6 – 12 months Hated new clothes Low mood, alienated and defended – lack of smiling mistaken

for lack of facial expression

▫Some Aspergian personality traits


10

Co-morbid ASD and SPAExplaining symptoms and planning intervention•Sleep▫ Poor clock or abnormal proprio-reception?

•Eating ▫ Limited repertoire - driven by sensory problems or repetitive

behaviours?

•Aversion to physical contact▫Driven by sensory defensiveness or autistic aloofness?

•Aggression▫ Sensory defensiveness or arising out of triad problems?

(holding)


11

Multiple co-morbidities

ADHD; ID; DCD; OCD; anxiety; depression; epilepsy; sensory impairment etc. Simply increases▫ the complexity of the child

▫ the need for imaginative assessment

▫ and creative solutions

▫ provided by an experienced and knowledgeable multidisciplinary team who can work together in whatever combination a particular child needs


12

Conclusion• Professionals assessing and managing children with

possible or actual social and communication disorders need to be well versed in SPAs

• They mimic, exacerbate and change autistic symptoms

• OT is a crucial component of any ASD service, both at the level of assessment, and therapeutics

• Assessment requires a team who assess children in more than one setting
