Speech may convey a sense of incoherence; the conversational style often includes monologues about topics that bore the listener, fails to provide context for comments, or fails to suppress internal thoughts.
Individuals with AS may fail to detect whether the listener is interested or engaged in the conversation.
Children with ASD often demonstrate enhanced perception of small changes in patterns such as arrangements of objects or well-known images; typically this is domain-specific and involves processing of fine-grained features.
these sensory responses are found in other developmental disorders and are not specific to AS or to ASD.
Of the other four ASD forms, autism is the most similar to AS in signs and likely causes, but its diagnosis requires impaired communication and allows delay in cognitive development; Rett syndrome and childhood disintegrative disorder share several signs with autism but may have unrelated causes; and pervasive developmental disorder not otherwise specified (PDD-NOS) is diagnosed when the criteria for a more specific disorder are unmet.
As a pervasive developmental disorder, Asperger syndrome is distinguished by a pattern of symptoms rather than a single symptom.
There is no evidence that these motor skills problems differentiate AS from other high-functioning ASDs.
Asperger syndrome (AS), also known as Asperger's, is a developmental disorder characterised by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior and interests.
