[Operationalized diagnosis of schizoaffective and cycloid psychoses].

Case histories of 128 patients suffering from functional psychoses were evaluated. The operational definitions for schizoaffective psychoses (SAP) of Kendell, Welner, Spitzer (RDC) and Feighner were applied. Of the 30 cases of SAP based on ICD 8 (295.7), Kendell's criteria were fulfilled in 97% Welner's in 77%, Spitzer's in 70% and Feighner's in 30%. The highly sensitive criteria of Kendell are best qualified for delineating the schizoaffective (sa) syndroms, but have the disadvantage of not requiring a time limitation when examining the longitudinal course of the illness. In this respect, the Welner criteria which also demonstrate high sensitivity were found to be more appropriate for the disease concept of the ICD 8. When using the schizoaffective criteria, a striking overlap was found with catatonic schizophrenia (Kendell and Welner diagnosed 33% as sa), paranoid schizophrenia (Spitzer 39%, Kendell and Welner 28%) and mania (Kendell and Welner 50% sa diagnoses). Of the SAP only 30% satisfied Perris' criteria for cycloid psychoses. Except for catatonic schizophrenia (47% overlap), the cycloid psychoses could be well distinguished from the other psychoses. cycloid psychoses therefore should not form a subgroup of the SAP. Kendell's criteria were found to be best qualified for the determination of the schizoaffective group. A higher specificity of the disease concept SAP may be achieved if we use time limitations such as Welner's. To avoid placing cycloid psychoses in the SAP category, the Perris criteria should be applied. Because of their high specificity, the criteria of Feighner and Spitzer were found to be inappropriate. In DSM-III the definition of "psychotic disorders not elsewhere classified" is weak. It lacks an operational definition for SAP so that DSM-III was not used for this investigation. In order to obtain a more homogeneous population not only in the schizoaffective group, but also in both of the two major psychoses, we find it legitimate to maintain the schizoaffective group and, at the same time, recognize the exceptional position of cycloid psychoses as separate groups.

[The concept of cycloid psychoses. Developments, clinical significance and the state of research].

Karl Leonhard developed the concept of cycloid psychoses by further elaborating previous findings of Carl Wernicke and Karl Kleist. A phasic alternating and recurrent as well as remittent course without residual states and a bipolar and polymorphous symptomatology are main features of cycloid psychoses. The symptom constellations are typical in a manner that, in most cases, allows establishing a diagnosis solely by carefully examining a cross-section of the clinical syndromes. 3 sub-forms are differentiated. Anxiety-happiness psychosis is characterised by extreme affective alterations with paranoid anxiety on the one hand and ecstasy with feelings of elation on the other. Formal thought disorder with incoherence, mainly as "incoherence of thematic choice", on the excited pole and perplexedness on the inhibited pole are the central elements of confusion psychosis. Motility psychosis shows hyperkinesis or akinesis of a purely psychomotor nature affecting predominantly expressive and reactive motions as main features. A description of Leonhard's highly operationalised diagnostic criteria for each sub-form of cycloid psychoses is followed by an account of the clinical significance of the concept of cycloid psychoses. Furthermore, important findings of recent research are summarised. The findings point to the fact that cycloid psychoses represent a nosological entity that can be clearly separated from schizophrenic as well as from affective psychoses. Schizophreniform, schizoaffective or acute transient psychotic disorders are also not identical with cycloid psychoses. According to the criteria of DSM-IV or ICD-10, cycloid psychoses are spread over a broad spectrum of heterogeneous diagnoses, thus hampering the recognition of the clinical and scientific importance of this homogeneous group of psychoses.

Psychogenic psychoses. A retrospective study with special reference to clinical course and prognosis.

The study comprises a retrospective evaluation of case records of 220 patients admitted for the first time with psychogenic psychosis with special reference to clinical course and prognosis within a period of 13--14 years. The reliability of the diagnosis at the time of the first admission is about 60% when the evaluation is based on positive criteria for psychosis. If the psychogenic psychoses are divided into subgroups, the reliability of the diagnosis of psychogenic affective psychoses is about 30%, whereas it is over 90% for psychogenic confusional psychoses and psychogenic paranoid psychoses. If subsequent cases of other functional psychoses (manic-depressive psychosis and schizophrenia) are subtracted, the diagnostic reliability is 50% (111 of 220 cases), which represents the number of retrospectively verified psychogenic psychoses. The frequency of recurrence of psychogenic psychosis was 18% (40), corresponding to 36% of psychogenic psychoses verified by retrospective evaluation (111 of 220 cases). The recurrences were mainly homologous, as heterologous recurrences developed only among the psychogenic affective psychoses (slightly less than half of the recurrences in question). Schizophrenia developed in only 10% (23), and subsequent episodes of manic-depressive psychosis occurred in 8% (18). The stability of psychogenic psychosis on recurrence of functional psychosis was 49% expressed in relation to all subsequent cases of functional psychosis. The over-all prognosis for the psychogenic/reactive psychosis is thus good as regards subsequent mental disease. Chronic functional psychosis (schizophrenia) developed in only 10% (and in less than 20% if the prognosis is assessed on the basis of the reliability of the diagnosis at the time of the first admission (about 60%)). However, in the group of psychogenic/reactive psychoses as a whole an overmortality of 100% was observed in the course of the 14 years, highest in the younger age groups.

Brief and acute psychoses: the development of concepts.

This paper reviews the conceptual history of brief and acute psychoses. As psychotic disorders of usually dramatic symptomatology but nevertheless with a usually benign course, brief and acute psychoses have the air of a paradox. Thus, they have posed specific problems in regard to nosology, diagnostics and aetiology. Despite a strong convergence of the descriptive elements, the historical concepts of brief and acute psychoses have yielded different answers to the questions raised. Kahlbaum and Kraepelin set the stage on which brief and acute psychoses appeared "atypical". The concept of "bouffée délirante" used degeneration theory as a background for nosological and aetiological allocation. Similarly, the concepts of cycloid psychoses, reactive (psychogenic) psychoses, emotional psychoses and atypical psychoses have provided diverging but interrelated ways to delineate brief and acute psychoses, to determine their nosological status and to explain the coexistence of severe disorder and favourable prognosis. Modern classifications, namely the acute and transient psychotic disorder of ICD-10 and the brief psychotic disorder of DSM-IV, reflect the varied history of the concept.

[Psychoses during the puerperium. Review of the literature].

More than half of the psychoses which develop a few weeks after delivery are manic depressive psychoses. A very limited fraction are schizoaffective psychoses. Up to one fourth are difficult to classify on account of dominating symptoms such as disturbances of consciousness and schizophrenic symptoms. No organic etiology has been found for these disturbances of consciousness. In British investigations, the hypothesis has been presented that these psychoses with atypical symptomatology represent a less serious variant of manic depressive psychoses. This question can only be solved by investigations concerning the etiology of manic depressive psychoses. In the present article, the hypothesis is presented that these psychoses may be reactive psychoses. Investigations concerning the etiology of reactive psychoses are necessary.

Reexamination of interictal psychoses based on DSM IV psychosis classification and international epilepsy classification.

We sought to examine interictal psychoses based on the international epilepsy classification and DSM IV criteria, with special attention paid to epilepsy types as well as to subcategories of psychoses. One hundred thirty-two outpatients were studied, each with definite evidence of both epilepsy and interictal psychosis clearly demarcated from postictal psychosis. We compared them with 2,773 other epilepsy outpatients as a control. Risk factors for psychosis were examined within the temporal lobe epilepsy (TLE) group and the more extended group of symptomatic localization-related epilepsy. Further, nuclear schizophrenia and other nonschizophrenic psychotic disorders were compared. We confirmed a close correlation between TLE and interictal psychoses. Within the TLE group, only early epilepsy onset and a history of prolonged febrile convulsions were revealed to be significantly associated with interictal psychosis. Within the symptomatic localization-related epilepsy group, such parameters as complex partial seizures, autonomic aura, and temporal EEG foci were closely associated with psychoses. There was also a significant difference between groups as to ictal fear and secondary generalization. Whereas patients with early psychosis onset and a low intelligence quotient were overrepresented in the nuclear schizophrenia group, drug-induced psychosis and alternative psychosis were underrepresented. TLE proved to be preferentially associated with interictal psychoses. Within the TLE group, medial TLE in particular was found to be more closely associated with psychosis. Our data support the original postulation of Landolt, stating that alternative or drug-induced psychoses constitute a definite subgroup of interictal psychoses, which are different from chronic epileptic psychoses that simulate schizophrenia.

A review of evidence for GABergic predominance/glutamatergic deficit as a common etiological factor in both schizophrenia and affective psychoses: more support for a continuum hypothesis of "functional" psychosis.

Virtually all antidepressant and antipsychotic drugs, including clozapine, rimcazole and lithium ion, are proconvulsants, and convulsive therapy, using metrazol, a known GABA-A antagonist, as well as electro-convulsive therapy, can be effective in treating both schizophrenia and affective psychoses. Many antidepressant and antipsychotic drugs, including clozapine, as well as some of their metabolites, reverse the inhibitory effect of GABA on 35S-TBPS binding, a reliable predictor of GABA-A receptor blockade. A review of relevant literature suggests that 1) "functional" psychoses constitute a continuum of disorders ranging from schizophrenia to affective psychoses with overlap of symptoms, heredity and treatments, 2) a weakening of GABergic inhibitory activity, or potentiation of counterbalancing glutamatergic neurotransmission, in the brain, may be involved in the therapeutic activities of both antidepressant and antipsychotic drugs, and 3) schizophrenia and the affective psychoses may be different expressions of the same underlying defect: GABergic preponderance/glutamatergic deficit. Schizophrenia and affective psychoses share the following: 1) several treatments are effective in both, 2) similar modes of inheritance, 3) congruent seasonal birth excesses, 4) enlarged cerebral ventricles and cerebellar vermian atrophy, 5) dexamethasone non-suppression. Both genetic and environmental factors are involved in both schizophrenia and affective psychoses, and several lines of evidence suggest that important environmental factors are neurotropic pathogens that selectively destroy glutamatergic neurons. One group of genes associated with psychoses may increase vulnerability to attack and destruction, by neurotropic pathogens, of excitatory glutamatergic neurons that counterbalance inhibitory GABergic neurons. A second group of genes may encode subunits of overactive GABA-A receptors, while a third group of genes may encode subunits of hypo-active glutamate receptors. Improved antipsychotic drugs may be found among selective blockers of GABA-A receptor subtypes and/or enhancers of glutamatergic neurotransmission. A mechanism similar to kindling, leading to long-lasting reduction of GABergic inhibition in the brain, may be involved in several treatments of psychoses.

Follow-up and family study of postpartum psychoses. Part I: Overview.

A group of 119 patients suffering from a severe psychiatric postpartum disorder who were admitted for the first time in their life to a psychiatric hospital has been investigated. The onset of illness occurred within 3 months following delivery. The patients represented 92% of the total sample fulfilling the inclusion criteria. A follow-up investigation was performed after a mean of 21 years (range 2-35 years). Of the patients 66% had nonpuerperal psychotic episodes in later life. The diagnosis, taking into account the long-term course, was affective psychosis in 57%, schizoaffective psychosis in 18%, schizophreniform psychosis in 12%, brief reactive psychosis in 4% and schizophrenia in 9%. A bipolar psychosis was found in 31%. The relation of unipolar to bipolar psychoses corresponded to that in a control group of affectively ill women without puerperal onset. The frequency of a manic syndrome in bipolar psychoses at the index episode was the same as in nonpuerperal episodes, which does not suggest a mania-provoking pathoplastic effect of the puerperium. The comparison with female nonpuerperal controls matched for age and diagnosis revealed evidence of a better long-term course in the index patients. The risk of a puerperal relapse for further pregnancies was 35%. The global morbidity risk for functional psychoses in first-degree relatives was 11%, with affective psychoses representing the majority of secondary cases (6.8%). The index patients showed a nonsignificant lower morbidity risk in relatives than a control group of psychotically ill women without puerperal onset. The major aetiological factor found for postpartum psychoses is the relation of these disorders to functional psychoses. There is strong evidence that the postpartum period tends to provoke affective psychoses and other nonschizophrenic psychoses, but not, or only to a lesser degree, narrowly defined schizophrenias. The liability to puerperal decompensations suggests some common pathophysiological mechanism, the nature of which remains unknown.

[Epileptic psychoses and their drug treatment].

This paper is concerned with classification, clinical-electroencephalographic correlation, principles of treatment, and pharmaceutic therapy of epileptic psychoses. Based on the system of the physically founded reversible psychoses, classification of epileptic psychoses is developed, which is easy to apply for clinical and research purposes. Its principles are the criteria of disturbance of consciousness and of connexion to epileptic seizures. Epileptic psychoses without disturbance of consciousness frequently go along with a forced normalization of epileptic EEG-changes. This clinical-electroencephalographic correlation is documented by the cases of a depressive-paranoid and a cenesthetic alternative-psychosis. Epileptic psychoses connected to seizures, going along with disturbances of consciousness, however, show, without any exception, a pathological changed EEG. Also in the cases of the often iatrogenically produced epileptic psychoses with disturbances of consciousness yet not connected to seizures, the EEG-results are of decisive diagnostic importance. Each of these three clinical-electroencephalographically defined groups of psychoses calls for concentration on particular pathogenetical aspects concerning a specific pharmaceutic therapy. The respective principles of treatment are developed in subtly differentiated ways and they are provided with suggestion as to medicamental treatment. Schizophrenia-like epileptic psychoses are a model for idiopathic schizophrenias and so important perspective opens up for research.

Cerebral systems in the pathogenesis of endogenous psychoses. 1974.

Mental process imply a harmonious functioning of psychic systems, assembled into larger units, psychic spheres (Table 1). Their neurophysiological representatives are brain systems of areas and pathways (Figs 1-4). Under functional and/or organic disturbances these systems originate the leading mental symptoms (Table 2) characterizing the diverse endogenous psychoses: hence, the latter's distinctive patterns. Accordingly, understanding and classification of psychoses should rest on the pathogenic dynamisms, not on clinical description. This is why Kleist's and Leonhard's conceptions of the endogenous psychoses surpass any other to exist. Kleist stands among the founders of psychiatry, by describing the "degeneration psychoses" and many single psychoses, as well as redefining, isolating and clarifying the progressive ones, later on renamed as schizophrenias (Table 3). Such pathogenic criterion may also be useful to define mental conditions other than psychoses, as hysteria, neuroses and psychopathic inferiority (Tables 4 and 5). One should consider here, besides the psychic systems and spheres involved, the way they were caught and the corresponding developmental phase. In Kleist's "degeneration psychoses"--cyclic or episodic (Table 6) the systems and spheres are disturbed by functional transient processes due to latent dispositions, while his and Leonhard's schizophrenias (Table 7) show a rather progressive, deteriorating course. The nature of the disorder is itself genetically determined, as is either its confinement to one sphere or its spreading out. The spread out pattern, while exceptional in schizophrenia, represents a rule for the "degeneration psychoses", in discussant's mind. Both groups may have symptoms alike by involvement of the same sphere (Table 8), but proper diagnosis is reached by taking pathogenesis into consideration.

[Epileptic psychoses and aggressiveness].

Aggressive behavior is studied in 60 in-, and outpatients with epileptic psychoses. Such psychoses were split in 2 groups: (a) Clear consciousness, and (b) Clouded consciousness. In turn, clear-consciousness epileptic psychoses were also split in 2 groups, namely episodic, and chronic psychoses. The results show there is a greater aggressivity within the psychotic symptoms period, if compared to the period free of symptoms. If drawn during the psychotic symptoms period, a comparison between these psychoses shows that clouded consciousness epileptic psychoses group features a greater amount of aggressive behavior. Chronic epileptic psychoses rank second. Finally, a lower aggression index is to be found among episodic epileptic psychoses group. No direct relationship between aggressive behavior, and epileptic seizures--such as focal, generalized, or mixed epileptic fits--could be found out.

[Alcohol consumption and alcohol-induced psychoses in Poland in the years 1956-1986].

The dependence between alcohol psychoses morbidity and the average alcohol consumption in Poland in the period of time from 1956 till 1986 was studied. Alcohol consumption in Poland between 1981 and 1986 was different than during all previous post-war period. Therefore, the analysis of dependence between alcohol psychoses morbidity and alcohol consumption was performed in 2 periods of time: 1956-1980 and 1981-1986. The frequency of the first hospitalization of men with alcohol psychoses for 100,000 of population was accepted as an alcohol psychoses morbidity factor. As an indicator of alcohol consumption the average consumption of all kind of alcohol beverages in conversion to pure alcohol per capita per year was accepted. During the years 1956-1980 such dependence was demonstrated as a square function: y = .3 X2, with the correlation coefficient r = .99, where X designates the average alcohol consumption per person per year. and y denotes the morbidity with alcohol psychoses. During the years 1981-1986 the decline of such dependence was observed (r = .65). In 1981 there was rapid decrease of alcohol consumption; such decrease intensified slightly in 1982. This went with deep decline of alcohol psychoses morbidity. In the years 1983-1985 rapid increase of alcohol psychoses morbidity incomparable with a slight increase of alcohol consumption was found. In 1986 small alcohol consumption was accompanied with inconsiderable fall of morbidity.(ABSTRACT TRUNCATED AT 250 WORDS)

Schizo-affective psychoses in childhood: a follow-up study.

A follow-up study of 16 schizo-affectives (part of a group of 57 children originally diagnosed as schizophrenic) is reported. All 57 patients were under 14 years. They were reinvestigated after an average follow-up period of 16 years (range 6 to 40 years). Of the 57 psychoses 28% had a typical schizo-affective character. In contrast to purely schizophrenic psychoses, we found an overrepresentation in the schizo-affective psychoses of affective psychoses and suicides in the ancestry. Further, in the schizo-affective psychoses there were more premorbidly well adjusted, harmonious personalities. In contrast, maladjusted, dishormonious, introverted characters predominated in purely schizophrenic psychoses. The schizo-affective psychoses had mainly an acute-recurrent character and followed a favorable course. The schizo-affective and affective phases were of significantly shorter duration than the schizophrenic episodes.

[Diagnostic shifts of functional psychoses in the transition from ICD-9 to ICD-10].

In order to identify diagnostic changes caused by the transition from ICD-9 to ICD-10, in a sample of 218 first hospitalised patients from the years 1980 and 1981, ICD-9 diagnoses were compared with ICD-10 diagnoses. For this comparison, functional psychoses were classified into five main diagnostic groups. Results showed a decreased frequency of the diagnostic groups schizophrenia, schizoaffective psychoses, and paranoid psychoses and an increased frequency of the diagnostic groups acute psychoses and affective psychoses. With the exception of acute psychoses and schizoaffective psychoses, a high agreement between ICD-9 and ICD-10 diagnoses was found, and the Kappa value was 0.70. With regard to the homogeneity of psychopathological symptoms, ICD-10 diagnoses showed no improvement over ICD-9 diagnoses. Nevertheless, ICD-10 diagnoses have gained in predictive validity because schizophrenia was further narrowed to cases with a more unfavourable outcome.

Cycloid psychoses predominate in severe postpartum psychiatric disorders.

BACKGROUND: The nosological status of postpartum psychoses has remained controversial because of their often 'atypical' symptomatology. A polydiagnostic approach may further clarify this issue. METHODS: In a retrospective study, we applied the ICD-10 and Leonhard's classification to 39 patients with severe postpartum psychiatric disorders. The patients were personally reexamined on average 12.5 years (6-26 years) after the onset of the illness. RESULTS: An acute onset and a polymorphous psychotic symptomatology with rapid changes characterized the majority of our cases. Unipolar depressive disorders (28%) and acute polymorphous psychotic disorders (21%) represented the largest proportions within the ICD-10-classification. Applying Leonhard's classification, over half the patients (54%) suffered from a cycloid psychosis. Among cycloid psychoses, motility psychoses clearly predominated. Schizophrenias occurred rarely (10%) according to both classifications. LIMITATIONS: Due to the unknown prevalence of the various diagnoses among women of child-bearing age, it is impossible to statistically infer a specific association between childbirth and a distinct diagnosis from our data. CONCLUSIONS: Our findings suggest that cycloid psychoses, in particular motility psychoses, account for the majority of postpartum psychoses, and do not support the hypothesis of a nosological independence of postpartum psychoses.

[Psychoses in multiple sclerosis--a reevaluation].

With the aim of reaching a new classification of psychoses with multiple sclerosis we reviewed the twentieth century literature for observations with regard to the subject, as well as 688 medical records of our patients, looking for the occurrence of paranoid and hallucinatory psychoses in the course of multiple sclerosis. Special attention was paid to the occurrence of cycloid psychoses. With multiple sclerosis, psychoses on the whole--but cycloid psychoses in particular--occur more frequently than in the general population. Women are affected just as frequently as men. Cycloid psychoses occur earlier in the course of the multiple sclerosis than the other psychoses; here, hallucinations occur with a higher frequency. Similar as in the case of HIV-infection, multiple sclerosis can act as a trigger of a cycloid psychosis. The results of our study indicate that men and women experience this disease as similarly threatening. A shortcoming of critical faculties based on the organic disease is an additional factor that favours the outbreak of such a psychosis.

Puerperal and cycloid psychoses. Results of a retrospective study.

Puerperal psychoses are traditionally considered to be nosologically unspecific. They are defined exclusively by their occurrence close to delivery. Attempts to further diagnostically subdivide puerperal psychoses have been prevented to date by the influence of Kraepelin's dichotomy. New possibilities of nosological differentiation arose out of Kasanin's (1933) description of schizoaffective psychoses and out of Leonhard's differentiated nosology (1986). The objective of the present, retrospective study was to apply Leonhard's nosology to 42 postpartal psychoses. Five diagnostic groups could be identified: 6 cases of manic-depressive disorder, 7 cases of pure depression, 8 cases of pure melancholia, 2 cases of unsystematic schizophrenia, and 19 cases of cycloid psychoses. For this reason we consider that the concept of the cycloid psychoses is appropriate for the characterization of a large proportion of childbed psychoses.

Three-year outcome of first-episode psychoses in an established community psychiatric service.

BACKGROUND: Changes in service provision, secular trends in substance misuse and changing social structures might affect outcome in psychosis. AIMS: To assess the three-year outcome of an inception cohort of first-episode psychoses treated in a modern, community-oriented service; to compare outcomes with an earlier cohort treated in hospital-based care; and to examine the predictive validity of ICD-10 diagnostic criteria. METHOD: Three-year follow-up (1995-1997) of an inception cohort of first-episode psychoses and comparison with two-year follow-up (1980-1982) of the Determinants of Outcome of Severe Mental Disorders (DOSMED) Nottingham cohort. RESULTS: On most outcome measures, non-affective psychoses had a worse outcome than affective psychoses. Affective psychoses had better outcome than previously reported. Substance-related psychoses had very poor occupational outcome. Similar proportions of the current and DOSMED cohort were in remission but the former were rated as having greater disability. CONCLUSIONS: In a modern community service, 30-60% of patients with first-episode psychoses experience a good three-year outcome. The ICD-10 criteria have good predictive validity.
