[Natural history of infantile autism (nosography)].

Natural history of infantile autism goes from its first description to current classifications. Most authors agree upon the perfect character of Kanner's description in 1943. But its situation in the nosography has much developed. The parution of 4th edition of Diagnostic and Statistical Manual of mental disorders (DSM IV) bring us to analyse this evolution and the place of autistic disorders in the pervasive developmental disorders, with this of associated pathologies. The comparison of current classifications (DSM IV, ICD 10, CFTMEA) allows us to do correspondence between each diagnostic category in psychosis or developmental disorders of these classifications. It exists a real concordance between DSM IV and ICD 10. The french classification of child and adolescent mental disorders (CFTMEA) proposes original categories.
