    Abstract:
    INTRODUCTION: The early development of children who have been diagnosed as suffering from autism and children with specific language disorder (SLD) is still an area of research that receives little attention. There is a need for descriptive patterns of the early stages in the development of the two groups that foster the formation of reliable early diagnoses. Aims. In this study we attempt to determine the incidence of different symptoms in the first two years in the life of children who were later diagnosed as suffering from autism or SLD and to confirm or refute the data that suggests a pattern of onset of the disorder that differs from one group to the other. PATIENTS AND METHODS: We compare the data concerning the development of a sample made up of 42 children with autism and 41 children with SLD, which was carried out by means of a retrospective analysis of the information obtained from the families in the evaluation and diagnosis processes that were conducted in our centre. More specifically, we compare information about the following variables: family history, parents' age at the time of pregnancy, parents' profession, position at birth and incidence by sex, information about prenatal, perinatal and postnatal aspects, eating and sleeping problems, the presence or absence of signs of passivity, traces of alarm during the first year, age of the child when the first suspicions appeared, symptoms or difficulties that are described, data linked to medical neurological explorations carried out and data related to motor development. RESULTS: Although there are numerous similarities in many of the variables studied in both groups, it seems that the earlier onset of symptoms, passivity and the absence of pointing behaviour are more frequent in the group with autism than in children with SLD. The latter present a specific difficulty in language, tantrums and poorer motor competencies. CONCLUSIONS: At present there is no single symptom in early development that is exclusive to any of the disorders described above, although it is possible to determine some significant differences between the two groups. There is also a need to conduct more studies in the same line as this one that take into account the patterns of early development of other the autistic spectrum disorders.
