Principal aim: the ways of onset of Pervasive Developmental Disorders remain until now less documentated and often limited retrospective anamnestic recostruction. The Authors describe the natural hystory and the onset of Pervasive Developmental Disorders (PDD) by the direct observation and the analysis of home movies (taped by the parents) whiwh report the early life's periods of patients with PDD. Methods: the Authors the home-movies of 26 subjects (18 boys and 8 girls), aged, at first observation, 30-60 months. The diagnosis was of Autistic Disorder in 16 subjects and of Pervasive Developmental Disorders Not Otherwise Specified in 10 subjects. The metodology used in observation of home movies consist of the ERC-A-III scored by a team of 4 expert clinicians in infancy psychopathology. The experts had to reach an agreement about every single item; The score obtained have been elaborated by ANOVA. Results: no significative differences have been found for the items in the range of age 0-12 months. In the range of age of 12-18 months 2 items have significative differences. After the 18 months of life 12 items have significative differences. Eight items have no significance differences in all the range of ages. The data analysis has allowed us the description of three different ways of onset and development: the regressive, fluctuating and pejorative. Conclusions: the 18° months of life represents an important limestone in the development of children with PDD. For having the possibility to indicate the risk indexes that anticipate the evolution of PDD before the 18° months, the analysis of the symptoms have to be integrated with the study of the course of the developmental competences; the period between 12-18 months could be a target period for the programs of prevention in pediatric fields. To recognize the precocious symptoms of autism and for decribing their evolution during the first two yers of life. Authors, by the analysis of data about the coming out and evolution of autistic symptoms, describe 3 kinds of PDD development: pejorative, regressive and floating. At last, the Authors suggest a checklist that could be used for first screening during pediatric observation.
