Dear all,

as mentioned at Annual Autism conference in Stockport a few months ago the USA has been considering the terminology associated with Autism. The extract below represents a fairly brief summary of planned changes to what autism is described as (ie Autism, aspergers, PDD etc).


Crucially the classic ‘Autism Triad’ of impairments is likley to change. As are the various subgroups we have come to describe different kinds of Autism.  It is unclear whether the UK will follow but it is a debate worth tracking.  



I have been watching the debate unfold and for those on ‘Linked in’ there are some good groups that help you surf the prevailing discussions.

The American Psychiatric Association has updated the proposed draft diagnostic criteria for the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM). Work Group members have proposed a new category of “autism spectrum disorder,” which incorporates the current diagnoses of autistic disorder (autism), Asperger’s disorder, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (PDD-NOS). This category reflects members’ conclusion that “a single spectrum disorder” better describes our current understanding about pathology and clinical presentation of the pervasive developmental disorders.The “autistic triad” will now become two:

1)     Social/communication deficits

2)     Fixated interests and repetitive behaviors

The proposed criteria for Autism Spectrum Disorder are:

Must meet criteria 1, 2, and 3 below:

1. Clinically significant, persistent deficits in social communication and interactions, as manifest by ALL of the following:

a. Marked deficits in nonverbal and verbal communication used for social interaction:

b. Lack of social reciprocity;

c. Failure to develop and maintain peer relationships appropriate to developmental level

2. Restricted, repetitive patterns of behavior, interests, and activities, as manifested by at least TWO of the following:

a. Stereotyped motor or verbal behaviors, or unusual sensory behaviors

b. Excessive adherence to routines and ritualized patterns of behavior

c. Restricted, fixated interests

3. Symptoms must be present in early childhood (but may not become fully manifest until social demands exceed limited capacities)

The rationale for this proposal includes the following.
