3-yr-old boy• Hyperactivity & aggressive behavior • He does not sit still in his nursery class. • Parents say he says some words and that he responds
depending on his “mood”. • They do not think anything is wrong; but the nursery teacher
insisted they see a doctor.

• Birth History is normal• Examination:
• interested in his surroundings • does not allow you to establish a rapport• frequently putting in and taking out phone
charger from plug-point.• Minimal response to parental requests
• There is no dysmorphology, skin is normal and there are no focal neurological deficits.

Autism Spectrum Disorder
*CDC, Autism and Developmental Disabilities
Monitoring Network. Identified Prevalence of Autism Spectrum
Disorders. 2012.
• Common Neurodevelopmental disorder • Prevalence (India): approx. 1-1.4/100 children• Incidence of ASD*: Males 1:54; Females 1:252• DSM-5 (Diagnostic & Statistical Manual of
Mental Disorders) • Past: autistic disorder/pervasive developmental
disorder

Diagnostic Criteria
A. Persistent deficits in social communication and social interaction
B. Restricted, repetitive patterns of behavior, interests, or activities
C. Present since the early developmental periodD. Significant impairment in current functioningE. Not better explained by ID/GDD

Hearing deficit, ADHD,
Intellectual disability
• Hearing problem: • Follows & uses gestures (good non-verbal
comm.)• Social interaction is as per age
• ADHD• Good interaction and use of speech• Co-morbid ASD may be +nt
• ID vs ID with ASD• Restricted interest or repetitive behaviour • Impairment in social interaction as per
developmental age

Specific Expressive
Verbal Delay
• The child has only Expressive Speech Delay • Follows all oral requests (Receptive Verbal
Communication)• Non Verbal is perfectly age appropriate• Social Behaviour is normal• R/o mild hearing loss by doing objective hearing
tests • Speech therapy
![Page 9: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/9.jpg)
Hearing Impairment
• Neither does the child speak nor does he consistently follow commands given to him orally;
• Responds to oral commands if accompanied by gestures.
• Follow & use gestures (Non verbal communication). • Social Behaviour is as per age.• R/o hearing loss by doing objective tests (BERA)• Counsel: Hearing Aids/speech training/cochlear
implant

Autism Spectrum Disorder:
• Poor Verbal & Non verbal Communication • Poor social behaviour and interaction: poor peer
play• Repetitive actions like spinning/flicking his fingers • Focussed more on a part of object, rather than
whole.• Investigations: Rule out hearing loss,
neurocutaneous lesions, obvious syndromes like Trisomy 21, Fragile X.
• Refer to a Developmental Pediatrician/Team.• Counsel: Increase direct interaction with caregivers.

Red Flags
• Decreased interaction with peers/friends• Does not play with toys appropriately• Fixed patterns of interest/activities• Lines things up• Odd movement patterns and/or repetitive behaviors• Demonstrates echolalia (repeats words)• Is hyperactive

Summary of ASD
• Primary physician/teachers usually suspect first• Impairment in social interaction and
communication with restrictive, repetitive pattern of activity, behaviour
• It is a clinical diagnosis - investigations have limited role
• Use MCHAT-R screening• Earlier you intervene better the outcome• Refer early• DSM-5 is current standard for diagnosis

Definition
• Group of neuro-developmental disorders manifesting as persistent difficulties in learning to efficiently
• Read (dyslexia) (80%)• Write (dysgraphia) or • Perform mathematical calculations
(dyscalculia) • Normal intelligence, hearing and vision• Conventional schooling • Adequate motivation and socio-cultural
opportunity

Anita, a 10-yr-old girl, studying in Grade IV
• C/o avoiding school, poor school performance for past few months & lying to parents about school work.
• She has also become quiet and aloof.• 1-year back: teachers pointed out that
she makes many spelling mistakes and cannot read her grade textbooks.
• Persistent pattern since Grade II – home tuition.
• Parents did not respond as she had done well in Pre Primary and she was otherwise intelligent.
![Page 20: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/20.jpg)
At this stage it is important
to assess how she is in her activities
of daily living!
• O/E: • dull and disinterested, • brightens up when you talk about dancing &
looks anxious again when you ask her about her studies.
• Focused CNS exam is normal.• No hearing or visual deficits on assessment
![Page 21: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/21.jpg)
Activities of Daily Living - Poor
• Rule out Birth Injuries/HIE• Dysmorphic features: R/o Genetic abnormalities• Delayed development: R/o Intellectual Disability• R/o Muscular/neurological disorders • R/o hearing and visual impairment, autism• Malnutrition, Chronic infection• Epilepsy (absence seizures)• Chronic absenteeism from school
![Page 22: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/22.jpg)
Good in her activities of daily living!
• How is her attention span, impulsivity and hyperactivity?
• How is her mood and motivation?• Does she show consistent patterns of
errors in her reading and writing?
![Page 23: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/23.jpg)
Good in her activities of
daily life!
• How is her attention span; what about hyperactivity?
• Children with ADHD are unable to learn due to inattention, inability to finish learning tasks
• With age, this becomes more obvious
• How is her mood?
• Worsening self-esteem & confidence• Isolation & lack of participation • Overtime, withdrawn, sad and depressed
![Page 24: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/24.jpg)
How is her motivation?
• Lack of motivation may be due to familial issues
• May be abuse• Or even in SLD due to constant failures,
criticism, comparison with siblings and peers.
• Accept the child’s weaknesses, de-focus from the weaknesses and focus on the child’s strengths.
![Page 25: Early Detection · •Poor Verbal & Non verbal Communication •Poor social behaviour and interaction: poor peer play •Repetitive actions like spinning/flicking his fingers •Focussed](https://reader033.vdocument.in/reader033/viewer/2022052002/601515bd7493de6e4b587827/html5/thumbnails/25.jpg)
Does she have patterns of errors in reading, writing & math inspite of normal IQ, vision & hearing?
• The child shows difficulty in reading, writing and maths for her grade-level, with a consistent pattern of errors.
• She reads hesitatingly, with errors, guesses (sight reads) words, skips words and entire lines, is very nervous while reading, and makes every excuse to avoid reading.

What is not SpLD?
ûBorderline ID (IQ 71 to 84) – Get an IQ test! ûMental retardation (IQ ≤ 70)ûVisual handicap (>60% disability) – Get an eye
exam!ûHearing handicap (> 60% disability) – Get a
hearing test!ûPhysical handicap (e.g. cerebral palsy)ûLanguage barrier – should be obviousûEmotional problems ûChronic medical problems
