[The problem of structure and psychotherapy of neuroses and psychoses from Lacan's and Mannoni's viewpoints].

The author tries to give you some idea of Lacan's and Mannoni's concept of neurosis and psychosis in a very short form. The French structuralistic school, whose pupils the psychiatrist Lacan and the psychoanalyst Mannoni are, approaches the problem of psychosis by analysing the structure of the language. Mannoni, uses this sometimes very difficult system of terms successfully in the psychotherapy of severely disturbed children (with autistic, psychotic symptoms).
