Autism: Oxidative Stress, Inflammation and Immune Abnormalities • Chauhan, Abha et al (2010) Autism: Oxidative Stress,
Inflammation and Immune Abnormalities. NY, CRC Press
• “…oxidative stress occurs in the autistic brain and results in neurodegeneration that in turn contributes to symptoms”
• “…axons of cholinergic neurons in white matter are primary site of oxidative damage”
• “…genetic predispositions to oxidative stress triggers…which alters neurotrophins”
Copyright © 2015 Anita Remig Cross Country Education
12
Autism: Oxidative Stress, Inflammation and Immune Abnormalities (Cont’d) • Environmental exposures to toxins and metals seep into
cells of body and brain
• Cells are altered: produce variant gene products
• Cell changes lead to prolonged oxidative stress
• Oxidative stress gives rise to inflammatory responses
• Methylation occurs---which adds new molecules onto strands of DNA altering gene structure and function
• Methylation causes inhibited methionine and capacity to get rid of toxins
Copyright © 2015 Anita Remig Cross Country Education
13
Childhood Developmental Disorders Causes include environmental toxins
added to susceptibility genes which give rise to:
Faulty environmental inheritance
Oxidative stress
Inflammation
Endocrine changes
Immune system errors (autoimmunity)
Neural tube migration disorders

Research Tool Can Detect Autism at 9 Months of Age • The ability to detect autism in children
as young as 9 months of age is on the horizon
• The Early Autism Study, led by Dr. Melissa Rutherford, (McMaster University), has been using eye tracker technology that measures eye direction while the babies look at faces, eyes, and bouncing balls on a computer screen
• Rutherford presented her peer-reviewed research at the 7th Annual International Meeting for Autism Research in London

15
Research Tool Can Detect Autism at 9 Months of Age (Cont’d)
• Autism is distinguishable at 9 months
• “I can do this in 10 minutes, and it is objective, meaning that the only measure is eye direction; it’s not influenced by a clinician’s report or by intuition. Nobody’s been able to distinguish between these groups at so early an age.“ Dr. Melissa Rutherford

Leo Kanner 1940 • “One of the children spun with great pleasure
everything he could seize upon to spin. Many of the children flapped their hands, flew into unpredictable bouts of rage and aggression, spoke in inexplicable ways if they spoke at all, sometimes referring to themselves as “you” or others as “I”, showed remarkable abilities like keen memory or perfect pitch but abject inability to perform simple tasks, obsessed over objects but ignored human beings.”

DSM-5®: Diagnostic Features
• The stage where the child’s functional impairment becomes obvious varies according to the individual and environment
• Supports may mask symptoms and delay diagnosis
• Manifestations of ASD vary greatly, hence “spectrum”
• Diagnosis most valid when using multiple sources of information: clinician observation, caregiver history, self-report
• Not a degenerative disorder; improves with training
Copyright © 2015 Anita Remig Cross Country Education
26
DSM-5®: Risk Factors
• Environmental risk factors: older parents, low birth weight, exposure to valproate in utero
• Genetic risk factors: some gene copy number variants are involved, but there is no gene or set of genes (ASD is polygenic---multitude of loci)
• Gender: 4 males to 1 female Copyright © 2015 Anita Remig Cross Country Education
27
DSM-5® Differential Diagnosis
• Rett syndrome
• Selective mutism
• Language disorder or Social pragmatic communication disorder
• Intellectual disability
• Stereotypic movement disorder
• Attention-Deficit Hyperactivity Disorder
• Schizophrenia

Autism and Sensory Processing Disorders: Shared White Matter Disruption
• PLoS One. 2014, 30;9(7). Chang YS et al
• Over 90% of children with Autism Spectrum Disorders (ASD) demonstrate atypical sensory behaviors
• Hyper- or Hypo-reactivity to sensory input or unusual interest in sensory aspects of the environment is now included in the DSM-5® diagnostic criteria
• There are children with sensory processing differences who do not meet an ASD diagnosis but do show atypical sensory behaviors to the same or greater degree as ASD children
Copyright © 2015 Anita Remig Cross Country Education
41
Autism and Sensory Processing Disorders: Shared White Matter Disruption (Cont’d)
• Sensory Processing Disorders (SPD) involve impaired white matter microstructure
• White matter microstructural pathology correlates with atypical sensory behavior
• ASD (n = 15), SPD (n = 16), typical children (n = 23)
• Both the SPD and ASD cohorts demonstrate decreased connectivity relative to controls in parieto-occipital tracts involved in sensory perception and multisensory integration
• ASD group alone shows impairment in temporal tracts to social-emotional processing

Eric Hollander, M.D. (2011)
• The Scientist 2011
• Dr. Hollander, in collaboration with a patient’s parent (Immunologist), used whipworm to treat autistic child
• The parent, Steward Johnson, showed Trichuris suis, a parasite found in the intestines of pigs, successfully treated autoimmune disorders
• Autism symptoms were the result of the immune system attacking specific brain cells
• Putting the two together, Mr. Johnson and Dr. Hollander tried the treatment — which has proven successful in curbing the patient's worst behaviors

Infant Start Therapy: Treatment based on Early Start Denver Model • Sally J. Rogers and Sally Ozonoff, Autism treatment in the
first year of life: A pilot study of Infant Start, a parent-implemented intervention for symptomatic infants. Journal of Autism and Developmental Disorders, Sept, 2014
• Intervention in 6-month-olds with autism eliminates symptoms, developmental delay
• 'Infant Start' therapy removes disabling delay before most children are diagnosed
• Treat at the earliest age when ASD appears---as young as 6 months old - significantly reduces symptoms so that, by age 3, most have no symptoms
Copyright © 2015 Anita Remig Cross Country Education
70
Infant Start Therapy
• Early identification crucial: Infant Start, was administered over a six-month period to 6- to 15-month-old infants who exhibited marked autism symptoms
• Delivered by the people who were most in tune with and spent the most time with the babies: their parents.
• Six out of seven children, caught up in all of their learning skills and their language by the time they were 2 to 3
• Taking away deficits and speeding up developmental rates---due to parents’ efforts
Copyright © 2015 Anita Remig Cross Country Education
71
Infant Start Therapy
• The intervention focused on increasing:
Infant attention to parent faces and voices
Parent-child interactions that attract infants' attention, bringing smiles and delight to both
Parent imitation of infant sounds and intentional actions
Parent use of toys to support social attention
• The treatment sessions included:

DSM-5® Diagnostic Criteria: Social (Pragmatic) Communication Disorder
Criterion A. Persistent difficulties in the social use of verbal and nonverbal communication:
1. Deficits in using communication for social purposes
2. Impairment in the ability to change communication to match context or the needs of the listener, such as speaking differently in the classroom as opposed to the playground
3. Difficulties following rules for conversation and storytelling, such as taking turns in conversation
4. Difficulty understanding what is not explicitly stated (making inferences) and nonliteral or ambiguous meanings of language (idioms, humor)
Copyright © 2015 Anita Remig Cross Country Education
74
DSM-5® Diagnostic Criteria: Social (Pragmatic) Communication Disorder (Cont’d) Criterion B: These deficits result in functional limitations in effective communication, social participation, social relationships, academic or occupational achievement (individually or in combination)
Criterion C: The onset of the symptoms is in the early developmental period (but deficits may not become fully manifest until social communication demands exceed limited capacities).
Copyright © 2015 Anita Remig Cross Country Education
75
DSM-5® Diagnostic Criteria: Social (Pragmatic) Communication Disorder (Cont’d)
Criterion D: The symptoms are not attributable to another medical or neurological condition or to low abilities in the domains of word structure and grammar and are not better explained by ASD, intellectual disability, global developmental delay or another mental disorder.
Copyright © 2015 Anita Remig Cross Country Education
76
DSM-5® Diagnostic Criteria: Social (Pragmatic) Communication Disorder (Cont’d)
• Diagnostic Features: Primary difficulties with pragmatics or
the social use of language and communication:
Understanding and following rules of social communication in natural contexts
Changing language according to the needs of the listener or situation
Following rules for conversation and storytelling
Associated feature is language impairment, ADHD, learning disorders, behavior problems

Research Review on SPCD: Norbury (2014) • Courtenay F. Norbury, (2014) Social (pragmatic)
communication disorder conceptualization, evidence and clinical implications. Journal of Child Psychology and Psychiatry 55:3, 204–216
• Thesis: Language impairment is primary and social deficits are secondary
• Social communication and pragmatic language are two separate issues with some overlap
• Pragmatics: understanding words in context, drawing inferences, and resolving ambiguity
Copyright © 2015 Anita Remig Cross Country Education
78
Research Review on SPCD: Norbury (2014) [Cont’d] • Social communication: ability to relate to
people using language
• Strong correlations presented between language test performance and measure of social deficits
• SPCD is conceptualized as a dimensional symptom profile
• SPCD presents across a range of neuro-developmental disorders: ADHD, Conduct Disorder, closed head injury, Williams Syndrome, Spina Bifida
Copyright © 2015 Anita Remig Cross Country Education
79
Research Review on SPCD: Norbury (2014) [Cont’d] • Lack of reliable and culturally valid assessment measures
to make a differential diagnosis between SPCD, ASD and Pragmatic Language Impairment (ICD-10)
• In the DSM-5®, one cannot have rote, repetitive behavior (RRB), yet research shows those subjects diagnosed with SPCD have both verbal and non-verbal RRB
• Sensory issues are not part of DSM-5® diagnosis, yet research confirms that SPCD subjects have sensory problems
• The author shows evidence to suggest that differential diagnosis of ASD and SPCD is not reliable
Copyright © 2015 Anita Remig Cross Country Education
80
Pragmatic Strategies
• Rote verbal monologues are common: use 3 sentence rule to avoid rote monologues
• Teach communicative intent: “when you talk it ought to mean you intend to share ideas”
• Conversational goal is the sharing of cogent and logical content among speakers: emphasize that talk is intended to share ideas Copyright © 2015 Anita Remig Cross Country Education
82
Pragmatic Strategies (Cont’d)
• Intentions are expressed in blunt, direct manner: teach contrast of rude vs. polite
• Eye-to-eye gaze is avoided: teach a system of 10 seconds on eye-to-eye, then 3 seconds for a break
• During conversation: teach child to continue eye gaze pattern (10 on, 3 off)
• Lack of question-asking: directly teach how to ask questions
Copyright © 2015 Anita Remig Cross Country Education
83
Pragmatic Strategies (Cont’d)
• Instrumental and personal need expressed more than descriptive statements: teach child to describe
• Child tends not to ask for clarification: teach the question, “Can you tell me more?”
• “Shared attention” lags behind: teach follow-up talk using one idea from co-speaker’s utterance
• Speech is often aprosodic: use tape recorder of child and adult model
Copyright © 2015 Anita Remig Cross Country Education
84
Pragmatic Strategies (Cont’d)
Early topic maintenance strategy in neuro-typical children is repetition: teach child to repeat word or phrase from co-speaker
Later, children use elaboration: help child to add more words to the repetition
Age 5 children smooth transitions into new topics: teach words such as “So, then, I mean to say”
