[Continuity and discontinuity of psychopathology: a study of patients examined as children and as adults. I. Antecedents of adult schizophrenic disorders].

The demographical stability of the Canton of Geneva made it possible for us to do a prospective study of all the children who had consulted the Child Psychiatry Service between 1963 and 1967 and who later consulted the public adult psychiatry services. On the basis of the adult diagnoses, wo looked for specific clinical "clusters" in childhood which would allow us to differentiate statistically the groups of children. We present here the results of the group of children who developed schizophrenia in adulthood. We found a specific childhood "cluster" which clearly distinguishes these children from the others. It includes: serious relational disorders, neurodevelopmental impairment, attention deficit and school learning disorders.
