“…Nosology As Maj [9] pointed out, the evolution of the concept of schizoaffective disorders is a reflection of the changes of the various concepts of schizophrenia and mood disorders over time. Schizoaffective disorders are considered a special variant of schizophrenia, a variant of mood disorders, an independent nosologic entity, a psychotic continuum between schizophrenia and mood disorders, a result of a comorbidity of schizophrenia with mood disorders, and an inhomogeneous group of psychoses.…”

Schizoaffective disorders are a clinical reality and their concept has a long history, but there are still problems regarding their diagnostic definition and nosologic categorization. The present definitions of the International Classification of Disease and the Diagnostic and Statistical Manual of Mental Disorders are not sufficient enough to define schizoaffective disorders, especially because of deficits on the longitudinal axis. Schizoaffective disorders occupy a position between schizophrenia and pure mood disorders, especially regarding prognosis and premorbid and sociodemographic variables. Schizoaffective disorders are recurrent disorders and, therefore, need prophylactic treatment. Suicidal symptomatology is extremely frequent in patients with schizodepressive episodes. The most severe type of schizoaffective disorders is the schizoaffective mixed type. Schizoaffective patients with mixed episodes retire more frequently and at younger ages than other patients with bipolar disorder.

“…In addition to this diagnostic dichotomy, many authors have described other groups of non-organic psychiatric patients and have claimed them as independent nosological groups. Thus, the concept of cycloid psychosis (1) has been used by many psychiatrists (2,3 ) to denote a specific group of syndromes that often are difficult to distinguish from the 2 major psychoses in that the clinical profile is polymorphous with a combination of manic-depressive and schizophrenic features. The psychotic manifestation, which often is preceded by a period of sleep disturbances, is characterized by an acute onset, with a rapid change from a state of health to a full-blown psychosis, often within a few hours or a few days.…”

Cycloid psychosis: regional cerebral blood flow correlates of a psychotic episode

Eight patients meeting Leonhard's criteria for cycloid psychosis were investigated on repeated occasions during a psychotic episode, with regional cerebral blood flow measurements and clinical ratings. The results showed that, at admission to the hospital, when the patients were clinically exacerbated, the mean hemispheric blood flow was significantly elevated compared with values from a normal control group. The hemispheric blood flow level covaried significantly with the degree of clinical symptoms, such that the more elevated the cortical blood flow was, the more behaviorally disturbed was the patient. At discharge from the hospital, the patients had no residual symptoms and the cortical blood flow was normal. These findings differ distinctly from those commonly made in other psychoses, such as schizophrenia.

“…This condition, at the extreme psychotic boundary of the bipolar spectrum, continues to challenge nosologists [38]. It overlaps with the French concept of 'bouffée délirante' [39] and the Scandinavian rubric of 'reactive psychosis' [40][41][42][43][44].…”

In reviewing recent findings on affective conditions in the interface of unipolar and bipolar disorders, we find evidence favoring a partial return to Kraepelin’s broad concept of manic-depressive illness, which included many recurrent depressives and temperamental variants. This review addresses methodologic, clinical, and familial considerations in the definition and characterization of a proposed spectrum of bipolar disorders which subsumes episodic and chronic forms. Episodic bipolar disorders are subclassified into bipolar schizoaffective, and bipolar I and II, and bipolar III or pseudo-unipolar forms. Chronic bipolar disorders could be either intermittent or persistent, and are subclassified into chronic mania, protracted mixed states, and rapid-cycling forms, as well as the classical temperaments (cyclothymic, hyperthymic, irritable and dysthymic).
