Brief report: Comorbid psychiatric disorders of autistic disorder

The behavioral and/or psychiatric symptoms in autistic people as described above have been viewed by many professionals dealing with autistic populations as “associated features of autism” that may result from these individuals' inability to cope with the environmental demands and physical discomfort. Traditionally, in treating individuals with autism, special education intervention including behavioral modifications has been the main emphasis. Such an approach has made some progress in milder and uncomplicated cases of autism. However, if many of these behavioral and/or psychiatric symptoms in those with more severe associated features can be viewed as symptoms of various comorbid psychiatric disorders, there are data suggesting that with an appropriate evaluation, predrug workups, a specific diagnosis, and multiple measures of outcome, pharmacotherapy can be a safe and efficacious adjunct treatment for some symptoms in autistic persons. Nevertheless, the data presented here were obtained mainly from autistic children. A great deal of work remains to be done Future research should put more emphasis on developing agreeable, reliable, and valid diagnostic instruments for identifying comorbid psychiatric disorders in autistic people. Future research should also emphasize employing a randomized double-blind placebo-controlled crossover design, as well as involving multicenters and using uniformed diagnostic criteria to study autistic adolescents and adults.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44613/1/10803_2005_Article_BF02172004.pd

Predictive value of subclinical autistic traits at age 14–15 months for behavioural and cognitive problems at age 3–5 years

It is unclear whether subclinical autistic traits at very young age are transient or stable, and have clinical relevance. This study investigated the relationship between early subclinical autistic traits and the occurrence of later developmental and behavioural problems as well as problems in cognitive and language functioning. Parents of infants aged 14–15 months from the general population completed the Early Screening of Autistic Traits Questionnaire (ESAT). Three groups of children with high, moderate, and low ESAT-scores (total n = 103) were selected. Follow-up assessments included the CBCL 1½–5 at age 3 years, and the SCQ, the ADI-R, the ADOS-G, a non-verbal intelligence test, and language tests for comprehension and production at age 4–5 years. None of the children met criteria for autism spectrum disorder at follow-up. Children with high ESAT-scores at 14–15 months showed significantly more internalizing and externalizing problems at age 3 years and scored significantly lower on language tests at age 4–5 years than children with moderate or low ESAT-scores. Further, significantly more children with high ESAT-scores (14/26, 53.8%) than with moderate and low ESAT-scores (5/36, 13.9% and 1/41, 2.4%, respectively) were in the high-risk/clinical range on one or more outcome domains (autistic symptoms, behavioural problems, cognitive and language abilities). Subclinical autistic traits at 14–15 months predict later behavioural problems and delays in cognitive and language functioning rather than later ASD-diagnoses. The theoretical implications of the findings lie in the pivotal role of early social and communication skills for the development of self-regulation of emotions and impulses. The practical implications bear on the early recognition of children at risk for behavioural problems and for language and cognitive problems
