[Epistemologic perspectives for a nosography in child psychiatry]

The author tries to question psychiatric nosography based on references. To do so, after defining nosography as well as psychiatric and medical nosography, he studies two ideas of thought. The first is a causal medical way dealing with child schizophrenia as developed in Eastern European psychiatry, whereas the second deals with the structural psychopathological way which describes the concept of child psychosis, the dominant way of dealing with child psychiatry in France.
