[Schizophrenias in DSM-IV and ICD-10 and French psychiatry]

DSM-IV and ICD-10 show the convergence of international nomenclatures of psychotic disorders. Their emphasis on antheorism and the definition of operational diagnostic criteria converge with one major trend in traditional French psychiatry which has been illustrated by Chaslin. The principal discrepancy which concerns chronic hallucinatory psychosis has been reduced by the restrictive conception of schizophrenic disorders in DSM-IV and ICD-10. Despite the attempt to define French empirical criteria, chronic hallucinatory psychosis has not been accepted by international classifications and is in pronounced decline in French scientific works. On the other had, the "bouffées délirantes aiguës", taken up by ICD-10, are acknowledged internationally.
