The main purpose of this chapter is to present the results of a review of communication interventions for children aged -years with autism spectrum disorders and to formulate recommendations for an evidence-based practice. The study, including reviews and primary studies, specifically focus interventions targeting children with diagnosis within the autism spectrum being on an early communicative level.
. Communication in children with Autism Spectrum Disorders ASD . . Difficulties with communication and language as part of the spectrumMajor advances have been made over the two past decades in understanding the socialcommunication difficulties of children with "SD, resulting in greater emphasis on early socialcommunication features in the diagnostic criteria. Most parents of children with autism first begin to be concerned that something is not quite right in their child s development because of early delays or regressions in the development of speech [ ]. Problems with communication, in terms of both understanding and expression, are often said to be one of the main causes of the severe behaviour problems that are common among persons with severe autism and mental retardation [ ]. The lack of meaningful, spontaneous speech by age five has been associated with poor adult outcomes [ , , , ]. Certainly, communication and communication problems are at the heart of what "SD is all about."lthough all persons diagnosed with autism have problems with communication, their type and degree vary a lot and the work of identifying different subgroups has just begun.

However, more recent research results indicate that the proportion of nonspeaking children with "SD is much smaller, approximately % to %, among those who received very early intervention [ ].Two phenotypes of speaking children with "SD were identified by Tager-Flusberg and Joseph [ ] children with normal linguistic abilities phonological skills, vocabulary, syntax, and morphology and children with impaired language that is similar to the phenotype found in specific language impairment. "nother potential subgroup may experience verbal dyspraxia or dyspraxia of speech [ ]. Voluntary motor control is disturbed in children with dyspraxia, which also affects their ability to imitate. The new research on the role of the mirror neurons in the parietal and frontal lobes may provide some answers on the relationships between motor control and imitation but also on the possible link with the development of intersubjectivity [ ].In spite of the heterogeneity of language abilities in children with "SD, social-communication or pragmatic impairments are universal...
