The Group of Schizoaffective and Related Psychoses-Critique, Record, Follow-Up, and Family Studies

In current psychopathological research there are at least two major groups of concepts in the field of psychoses with good prognosis: the more traditional concepts of ‘bouffée délirante’, cycloid psychoses and Kasanin’s ‘schizoaffectives’ – on the other hand the modern idea of ‘concurrent schizoaffective psychoses’ like the operational criteria of Kendell, Welner, RDC, DSM-IIIR and ICD-10. Reviewing previous studies, ‘bouffée délirante’ and cycloid psychosis were found to form a homogeneous group which is very well delineated from affective and schizophrenic psychosis – to some extent also from the modern criteria of ‘concurrent schizoaffective psychoses’.

Cycloid Psychoses and Schizoaffective Psychoses – A Comparison of Different Diagnostic Classification Systems and Criteria

Zaudig¹

1990

“…The last point, the prognosis, is disregarded by Angst. Corresponding to Weiner et al [28], he requires that only those psychoses should be called schizo-affective which on the one hand display severe affective symptoms but simultaneously schizophrenic symptoms so that the diagnosis of a purely affective psychosis can be excluded. On the other hand it is supposed that a sufficient number of affective manifestations in the long-term devel opment would question the diagnosis of schizophrenia.…”

Long-Term Prognosis and Course of Schizo-Affective, Schizophreniform, and Cycloid Psychoses

1983

From the Bonn study including 502 patients followed up an average 22.4 years after onset of schizophrenic disease diagnosed according to the criteria of K. Schneider, we selected 113 cases of schizo-affective, schizophreniform, and cycloid psychoses in accordance to the definitions given by Kasanin, Retterstøl, Angst, and Leonhard. These psychoses have a better prognosis than the whole sample: characteristic residues are seen more rarely, complete remissions and noncharacteristic residues more frequently. This group of psychoses differs from the whole sample in the hereditary taint, too: the morbidity risk with affective psychoses and with schizophrenic psychoses in first- and second-degree relatives is higher than in the total sample of the Bonn study. In spite of the better prognosis and other differences described in the paper, we believe that these results do not justify the classification of schizo-affective and related disorders as an independent disease group. Between these different subtypes of schizophrenia only a differential typology and not a differential diagnostic is possible.

“…In a two-part study (Croughan et a l, 1974;Weiner et al 1974) dealing with 'schizo affective and related psychoses', the St. Louis Group initially divided these clinical states into two large groups, depending on whether sufficient affective symptoms ('full' criteria) were present to satisfy their strict research criteria (Feighner et a l, 1972) for depression or mania (Group A) or not (Group B). These two groups were then subdivided on the basis of whether they demonstrated two to five 'qualitatively different severe thought or behavior disorders' (subgroups Al and Bl) or only one such abnormality (subgroups A2 and B2).…”

“…Indeed, in their papers on 'the group of schizo-affective and related psychoses', the St. Louis Group Weiner et al, 1974) spoke of a 'persistent enigma'. They felt that much of the confusion in this area stemmed from the fact that too many terms have been used, at times interchangeably, with the result that the various syndromes 'bear little, if any, resemblance to one another' ( Weiner etal., 1974).…”

Schneider-Negative Schizophrenia and Schizo-Affective Illness

Koehler¹,

Brüske²,

Jacoby³

1978

A slightly modified version of provisional research criteria for so-called ‘schizo-affective and related psychosis’, as recently published by the St. Louis Group, was used to investigate the case records of 116 Schneider-oriented first admissions of schizophrenics without first rank symptoms (Schneider-negative) who were hospitalized in a German center during the years 1962–1971. The sample contained 19.8% (23 cases) of research diagnosable schizo-affective illness as thus defined. ‘Full’ affective research criteria were satisfied by 13 of these schizo-affectives, and 10 were able to fulfill the ‘adjusted’ affective criteria assumed to be indicative of labile mixed mood states. The sample was then further analyzed in terms of ‘schizophreniform’ psychoses and ‘atypical schizophrenia’. The findings seem to support the view that a non-negligible segment (23.3%) of Schneider-negative schizophrenia actually may represent either research diagnosable schizo-affective or affective disorders or satisfy criteria for both diagnoses.
