[Contribution to the classification of endogenous psychoses]

The authors intend to describe the main points in endogenous psychoses classification according to H.J. Bochnik's criteria. The chief aspect thereby is the prognosis in terms of orientation of a certain symptomatology--either "phasic" or "process"--forming course. On the other hand phasic schizo-affective psychoses are called atypic-phasic psychoses and are incorporated in the group of phasic psychoses. In all cases a separate consideration is recommended as far as psychiatric research is concerned.
