The term 'semantic pragmatic disorder' has been around for nearly l5 years. Originally it was only used to describe children who were not autistic.
Features it includes are:-
Children with this disorder have problems understanding the meaning of what other people say, and they do not understand how to use speech appropriately themselves.
Soon both research and practical experience yielded two important findings:
For a while some language therapists maintained there was still an important difference between children with semantic pragmatic disorder and children who were truly autistic. They believed the autistic features seen in children with semantic pragmatic disorder were only a result of their difficulty with language.
However, further research has shown that there is probably a single underlying cognitive impairment which produces both the autistic features and the semantic pragmatic disorder . The fact that children with semantic pragmatic disorder have problems understanding the meaning and significance of events, as well the meaning and significance of speech, seems to bear this out.
Eventually the idea of an autistic continuum was used to explain the situation. All the children on the continuum have semantic pragmatic difficulties, but the degree of their other autistic impairments can be severe or moderate or mild. This parallels the autistic continuum relating Asperger syndrome, where all the children have a marked social impairment but those with Asperger syndrome have only a relatively mild and subtle language impairment.
It seems that children who are diagnosed as having a semantic pragmatic disorder might more accurately be described as high-functioning autistic. Clinicians tend to give all autistic children who have good intelligence the label Asperger syndrome, even if a child actually has very limited speech. But there are important differences between bright autistic children with semantic pragmatic difficulties and bright autistic children with Asperger syndrome. Children with semantic pragmatic difficulties have usually learnt to talk late, whereas (according to diagnostic guidelines) children with Asperger syndrome were able to talk in sentences by the age of three. Also children with semantic pragmatic difficulties do better on performance IQ tests than verbal IQ tests, whereas with children with Asperger syndrome the results tend to be the other way round. However, if a child with semantic pragmatic difficulties eventually becomes a fluent talker, the difference between the labels 'high functioning autistic' and ' Asperger syndrome' becomes fairly academic.
There is another aspect to the issue of labelling which is altogether more emotive. Many parents feel much more able to cope with the idea of their child having semantic pragmatic language disorder than with the idea of their child being a high functioning autistic. But many other parents find the label semantic pragmatic disorder frustrating and baffling, as they only begin to really understand their child's behaviour when they realise he or she has a form of autism.
Yet another issue is the provision of resources. It is a sad truth that many high functioning autistic children are denied the kind of educational language provision they desperately need, purely because of the word 'autism'. These children are more likely to be accepted into language units and schools when they have the label of semantic pragmatic language disorder. Perhaps the only real solution is to educate the educators, so they begin to understand the wide spectrum of autistic disorders, and to forget dated stereotypes. Even better, perhaps they could learn to look beyond the label and to see the child.
