peers. Often they cease their attempts because of the cruel ridicule, and remain extremely socially isolated. Yet, they honestly desire success in interpersonal
relationships, and are often quite puzzled when they do not succeed.

They often have both fine and gross motor deficits, including clumsy and uncoordinated
movements and odd postures.

Recent retrospective review of the original four Asperger cases reported that these children actually meet current DSM-IV
1
criteria for Autistic Disorder.
11
As DSM-IV is now written, if criteria for Autistic Disorder are met, this precludes a diagnosis of Asperger disorder.

2.1.3 Atypical Autism PDD Not Otherwise Specified PDD-NOS
These diagnoses are used when clinically significant autistic symptomatology is present, including deficits in reciprocal social interactions,
verbal or nonverbal communication, or stereotyped behavior, interests, and activities, but full criteria are not met for an alternative specific diagnosis under
the autistic spectrum or pervasive developmental disorder PDD umbrella; for example, in a child who does not meet the required total of 6 of the possible 12
criteria for the diagnosis of Autistic Disorder, or who had symptom onset after age 36 months. Also, children whose symptoms are atypical or not as severe would be
coded under this diagnosis.
1
Atypical autism PDD-NOS is not a distinct clinical entity with a specific definition, although individuals given this diagnosis are
traditionally thought to have milder symptoms. PDD-NOS is a diagnosis by exclusion of the other autistic spectrum disorders.
12
It is often used as a ―default‖ or ―wastebasket‖ diagnosis when either insufficient or unreliable information is
available, or when the practitioner is hesitant to use the term ―autism.‖ Screening and diagnostic procedures for atypical autismPDDNOS is the same as for the
other autistic spectrum disorders,as is management.

2.1.4 The Diagnosis of Autism Spectrum Disorder
In evaluating a child, clinicians rely on behavioral characteristics to make a diagnosis. Some of the characteristic behaviors of ASD may be apparent in the
first few months of a child‘s life, or they may appear at any time during the early years. For the diagnosis, problems in at least one of the areas of communication,
socialization, or restricted behavior must be present before the age of 3. The diagnosis requires a two-stage process. The first stage involves developmental
screening during ‗well child‖ check-ups; the second stage entails a comprehensive evaluation by a multidisciplinary team.
2
Comprehensive Diagnostic Evaluation
The second stage of diagnosis must be comprehensive in order to accurately rule in or rule out an ASD or other developmental problem. This
evaluation may be done by a multidisciplinary team that includes a psychologist, a neurologist, a psychiatrist, a speech therapist, or other professionals who diagnose
children with ASD. Because ASD‘s are complex disorders and may involve other neurological or genetic problems, a comprehensive evaluation should entail
neurologic and genetic assessment, along with in-depth cognitive and language testing.
3
In addition, measures developed specifically for diagnosing autism are often used. These include the Autism Diagnosis Interview-Revised ADI-R
13
and
the Autism Diagnostic Observation Schedule ADOS-G.
14
The ADI-R is a structured interview that contains over 100 items and is conducted with a
caregiver. It consists of four main factors —the child‘s communication, social
interaction, repetitive behaviors, and age-of-onset symptoms. The ADOS-G is an observational measure used to ―press‖ for socio-communicative behaviors that are
often delayed, abnormal, or absent in children with ASD.Another instrument often used by professionals is the Childhood Autism Rating Scale CARS.
15
It aids in evaluating the child‘s body movements, adaptation to change, listening response,
verbal communication, and relationship to people. It is suitable for use with children over 2 years of age. The examiner observes the child and also obtains
relevant information from the parents. The child‘s behavior is rated on a scale based on deviation from the typical behavior of children of the same age.
