DSM-5 Field Trial Professional Volunteers .From Darrel A. Regier, M.D.To [email protected] Thank you for participating in the DSM-5 Field Trials in Routine Clinical
Practice Settings! This important part of the DSM-5 Field Trials will test the feasibility and clinical utility of the proposed diagnostic criteria and measures for routine practices.

Autism Spectrum DisorderAutism Spectrum Disorder
They are defined as a group of biologically based neurodevelopment disorders that
share two common areas of concern
in social interactions
Restricted and repetitive interests or
behaviors
Qualitative impairments in
communication &

Diagnosis of ASDDiagnosis of ASD
In DSM-IV-TR and ICD-10 diagnosis has been based on deficits in three core domains: (1)social impairments, (2) communication difficulties, and (3) stereotyped and repetitive behaviours
In DSM-5 (and the proposed ICD-11 criteria) diagnosis is based on deficits in two core dimensions: 1.Social-communication difficulties2.Repetitive behavior

RULES FOR TREATMENT OF ASD
PHARMACOLOGICAL DRUGS HAVE NO ROLE IN TREATING OF ASD BUT OF NON SPECIFIC/ SYMPTOMATIC TREATMENT
INTENSIVE BEHAVIOR MODIFICATION SESSIONS OF AT LEAST 25 HOURS PER WEEK IS THE IDEAL TREATMENT NOWADAYS
![Page 21: Autism and early diagnosis (red flags)](https://reader033.vdocuments.net/reader033/viewer/2022051101/5a64c2087f8b9aa6148b4783/html5/thumbnails/21.jpg)
Autism was considered as disorder without hope, but now it is recognized as treatable for many patients especially who are diagnosed early and receive ,,,,,,
INTENSIVE BEHAVIOR INTERVENTIONS
![Page 22: Autism and early diagnosis (red flags)](https://reader033.vdocuments.net/reader033/viewer/2022051101/5a64c2087f8b9aa6148b4783/html5/thumbnails/22.jpg)
MEDICAL LITERATURE SAYS NO, BUT NOWADAYS WITH
ADEQUATE INTENSIVE REHABILITATION
SESSIONS
THE IMPROVEMENT CAN BE SO GREAT THAT IT COULD
JUSTIFY THE USAGE OF THE WORD
TREATED > CURE

SOMETIMES
WITH ADEQUATE INTENSE REHABILITATION
CHILDREN WITH HIGH RISK FOR DEVELOPING ASD
DON’T DEVELOP IT .

If your patient /child is
at risk for developing

and if you are willing to put effort in helping him,,
attend my presentation thoroughly

Genetics __________
High concordance rate in monozygotic twins
Increased incidence in siblings
Candidate genes : 3-7 genes identified in family studies
![Page 27: Autism and early diagnosis (red flags)](https://reader033.vdocuments.net/reader033/viewer/2022051101/5a64c2087f8b9aa6148b4783/html5/thumbnails/27.jpg)
Is there an increased risk of having another child with autism (recurrence)?
The incidence of autism in the general population is 0.2-1%, but the risk of having a second (or additional) autistic child increases almost 50-fold to approximately 10 to 20%.

Simple test for early screening autism
Infants who don't respond to their name by 1 year of age appear to be more likely to be diagnosed with an autism spectrum disorder or other developmental problem by the age of 2.

Clinically identifying children with autism
Level one
Routine Developmental Surveillance and Screening Specifically for Autism
• Should be performed on all children.
• Involves first identifying those at risk for any type of atypical development, followed by identifying those specifically at risk for autism.
![Page 57: Autism and early diagnosis (red flags)](https://reader033.vdocuments.net/reader033/viewer/2022051101/5a64c2087f8b9aa6148b4783/html5/thumbnails/57.jpg)
Clinically identifying children with autism
Level Two
Professional Diagnosis and Evaluation of Autism
Involves a more in-depth investigation of already identified children and differentiates autism from other developmental disorders.

Pediatrician CHAT Probes
Does the child: Make eye contact? Look at object to which you point excitedly? Pretend together? Point, looking at your face, to object requested? Build a tower of bricks?
![Page 63: Autism and early diagnosis (red flags)](https://reader033.vdocuments.net/reader033/viewer/2022051101/5a64c2087f8b9aa6148b4783/html5/thumbnails/63.jpg)

Lack of pointing per parents and doctors: medium risk

Does your child: Enjoy being bounced on your knee? Have interest in other children? Like climbing? Like playing peek-a-boo? Point to ask for something? Point to show interest? Plays with toys as toys? Brings objects to show you?

When and what laboratory investigations are indicated for the diagnosis of autism? (continued)
Other tests There is insufficient evidence to support the use of other tests such as: hair analysis for trace
elements celiac antibodies allergy testing (particularly
food allergies for gluten, casein, candida, and other molds)
immunologic or neurochemical abnormalities
micronutrients such as vitamin levels
intestinal permeability studies
stool analysis urinary peptides mitochondrial disorders
(including lactate and pyruvate)
