  • By the end of the Webinar, participants will be
    able to
  • Recognize the early warning signs of autism
    spectrum disorders (ASD)
  • Describe the recommendations put forth in the 2
    AAP Autism Clinical Reports regarding
    identification and management of ASDs

Developmental Surveillance Screening Policy
Statement Goals
  • Increase identification of children with
    developmental disorders by child health
    professionals
  • Improved surveillance and screening
  • Concrete guidelines (algorithm)
  • Eliminate barriers (e.g. reimbursement, time)
  • Improve medical assessment

5
Definitions (AAP, 2006)
  • Developmental surveillance
  • A flexible, longitudinal, continuous, and
    cumulative process whereby knowledgeable health
    care professionals identify children who may have
    developmental problems
  • Developmental screening
  • The administration of a brief standardized tool
    aiding the identification of children at risk of
    a developmental disorder
  • Not diagnostic!
  • Developmental evaluation
  • Aimed at identifying the specific developmental
    disorder or disorders affecting the child

6
Child Development
  • Its more than height and weight
  • Observing how children play, learn, speak and act
  • Different areas of development
  • Social, communication, cognitive, gross motor,
    fine motor, adaptive
  • Monitoring milestones can offer early signs of
    delay including signs of autism spectrum disorders

7
Autism Spectrum Disorders
  • Problems with socialization
  • Problems with communication
  • Unusual behaviors

8
Parental Concerns (Wiggins, Baio, Rice, 2006)
  • Recent study by CDC indicated most children with
    an ASD diagnosis had signs of a developmental
    problem before the age of 3, but average age of
    diagnosis was 5 years.

9
Early Development
  • Babies start communicating and relating to other
    people at birth
  • Continued social-emotional development is key to
    forming strong relationships and continued
    learning

10
By the end of 3 months
  • Begin to develop a social smile
  • Enjoy playing with other people and may cry when
    playing stops
  • Become more expressive and communicate more with
    face and body
  • Imitate some movements and facial expressions

11
By the end of 7 months
  • Smile back at another person
  • Respond to sound with sounds
  • Enjoy social play
  • Red Flags
  • No big smiles or other warm, joyful expressions
    by six months or thereafter
  • No back-and-forth sharing of sounds, smiles, or
    other facial expressions by nine months or
    thereafter

12
By the end of 12 months
  • Use simple gestures
  • Imitate actions in their play
  • Respond when told no
  • Red Flags
  • No back-and-forth gestures, such as pointing,
    showing, reaching, or waving bye
  • Not answering to ones name when called
  • No babbling mama, dada, baba

13
Joint Attention and Social Engagement
14
By the end of 18 months
  • Do simple pretend play
  • Point to interesting objects
  • Use several single words unprompted
  • Red Flags
  • No single words by 18 months
  • No simple pretend play

15
By the end of 2 years
(24 months)
  • Use 2- to 4-word phrases
  • Follow simple instructions
  • Become more interested in other children
  • Point to object or picture when named
  • Red Flags
  • No two-word meaningful phrases (without imitating
    or repeating)
  • Lack of interest in other children

16
  • Red Flag Any loss of speech or babbling or
    social skills
  • Regression at any age is cause for immediate
    referral

Key Points
  • Medical home center for ongoing management
  • Cornerstone of treatment
  • Educational interventions, developmental and
    behavioral strategies
  • Early, intensive intervention is vital
  • Pediatricians can support families by providing
    information and access to resources

Myers SM, Johnson CP, and the Council on Children
with Disabilities, Pediatrics 20071201162-1182
37
The Autism Toolkit
  • AUTISM Caring for Children With Autism Spectrum
    Disorders A Resource Toolkit for Clinicians was
    developed by the AAP Autism Subcommittee to
    support health care professionals in the
    identification and ongoing management of children
    with ASDs in the medical home

38
Medical Management of Children with ASD Includes
  • Effective treatment of coexisting medical
    problems such as seizures, challenging behaviors,
    and sleep disorders may allow the child to
    benefit more fully from educational interventions
  • Medication management of symptoms of inattention,
    impulsivity, irritability, aggression
  • Pediatricians can help families to understand how
    to evaluate the evidence regarding Complementary
    and Alternative therapies

39
ASD Management
  • Outcomes are variable
  • Behavioral characteristics change over time
  • Most remain on spectrum as adults
  • Ongoing problems with independent living,
    employment, social relationships and mental
    health
  • Predictors of better outcome
  • Earlier age of diagnosis and treatment
  • No cognitive impairment
  • Early language and nonverbal skills
  • Social skills
  • Not presence, degree of autistic symptoms

40
Treatment
  • Goals
  • Minimize core features and associated deficits
  • Maximize functional independence and QOL
  • Alleviate family stress
  • Educational intervention
  • Developmental Therapies
  • Communication
  • Sensory, fine motor, gross motor
  • Behaviorally Based treatments
  • Core and associated symptoms
  • Social skills
  • Medical or biologic treatments
  • Support family in home and community

41
Education
  • Cornerstone of management
  • Curricula should include
  • Academic learning

    modalities
  • Incorporate strong components of family training
    and support
  • Programs differ in philosophy emphasis

Myers Johnson, PED 2007
42
Behavioral Intervention
  • ABA (Applied Behavioral Analysis)
  • General behavioral teaching approach involves
    reinforcement and consequences to shape behavior
  • All of our parents used it!
  • Involves the A, B, Cs
