Autistic spectrum disorder: diagnostic difficulties.

Abstract

Recognition of the autistic spectrum disorders is becoming more widespread amongst basic scientists, clinicians, and the general population. The term does not imply anything about pathology or aetiology, although it has proved to be a useful concept clinically. From Kanner's classical autism the concept has widened in scope to include milder and more subtle impairments. From a clinical perspective, there are many alternative diagnoses in an individual with autistic-like symptoms, and thorough investigation is necessary to exclude these.

Systematic screening for subtelomeric anomalies in a clinical sample of autism.

High-resolution karyotyping detects cytogenetic anomalies in 5-10% of cases of autism. Karyotyping, however, may fail to detect abnormalities of chromosome subtelomeres, which are gene rich regions prone to anomalies. We assessed whether panels of FISH probes targeted for subtelomeres could detect abnormalities beyond those identified by karyotyping in 104 individuals with Pervasive Developmental Disorders (PDDs) drawn from a general clinical population. Four anomalies were detected by karyotyping, while no additional anomalies were detected by subtelomere FISH or by probes targeted for 15q11.2q13 or 22q11.2 in subgroups of our sample. We conclude that while karyotyping may be more broadly indicated for autism than previously supposed, subtelomere FISH appears less likely to be a useful screening tool for unselected PDD populations.

A comparative study of the use and understanding of self-presentational display rules in children with high functioning autism and Asperger's disorder.

The use and understanding of self-presentational display rules (SPDRs) was investigated in 21 children with high-functioning autism (HFA), 18 children with Asperger's disorder (AspD) and 20 typically developing (TD) children (all male, aged 4- to 11-years, matched on mental age). Their behaviour was coded during a deception scenario to assess use of SPDRs; understanding of SPDRs was assessed via three real/apparent emotion-understanding vignettes. The children with HFA and AspD used less effective SPDRs than the TD children, but there were no group differences in understanding SPDRs. The children with HFA and AspD did not differ on their use or understanding of SPDRs, and the results are discussed in relation to the similarities and differences between these diagnostic conditions.

Clarifying the associations between language and social development in autism: a study of non-native phoneme recognition.

Autism spectrum disorders (ASDs) are characterized by correlated deficiencies in social and language development. This study explored a fundamental aspect of auditory information processing (AIP) that is dependent on social experience and critical to early language development: the ability to compartmentalize close-sounding speech sounds into singular phonemes. We examined this ability by assessing whether close-sounding non-native language phonemes were more likely to be perceived as disparate sounds by school-aged children with high-functioning ASD (n = 27), than by unaffected control subjects (n = 35). No significant group differences were observed. Although earlier in autistic development there may exist qualitative deficits in this specific aspect of AIP, they are not an enduring characteristic of verbal school-aged children with ASD.
