IntroductionThe Autism Spectrum Disorders are group of conditions characterised by qualitative impairments in social communication; in the interaction and imagination; with a restricted range of interests and stereotyped repetitive behaviours. Frequently, there is a delay in the age of detection, and therefore in starting multidisciplinary evaluations and interventions, which may result in a worst prognosis and an impaired quality of life for both children and parents.Some clinical and epidemiological data are described, including the age of detection and main initial complaints present in children with autism disorders from a paediatric neurology centre.
