Prognosis of paranoid states in relation to the clinical features

Abstract

Scandinavian psychiatrists acknowledge endogenous psychoses which are neither schizophrenic nor manic-depressive, i.e., above all the "reactive psychoses" and the "schizophreniform psychoses", both of which differ from schizophrenia in their features as well as in their good prognoses. These Scandinavian diagnoses bear relationships to psychoses, which I separate from schizophrenia. In the present paper, paranoid states are discussed with regard to their clinical pictures and their good prognoses. Among these are the "cycloid psychoses". Patients suffering from these diseases recover from every phase, though most of the German psychiatrists consider them schizophrenic. Among the cycloid psychoses, the "ansiety happiness psychosis" shows ideas of reference on the one hand and ecstatic ideas on the other. In "inhibited confusion psychosis", the patients are suffering from ideas of reference and ideas of significance; in "excited confusion psychosis", from misidentifications of persons. The other symptoms which occur--anxiety, happiness, stupor, incoherent pressure of speech--confirm the cycloid psychoses and disprove schizophrenias. Besides the already mentioned psychoses, there is a monopolar psychosis, "suspicious depression", in which ideas of reference and ideas of guilt mix. It is extremely important, not only for theoretical but also practical reasons, to separate from schizophrenia paranoid states which terminate in complete recovery from every phase.
