“…These features are acute onset, shifting symptomatology, emotional turmoil, perplexity, and changes in the psychomotor activity. This has led some authors to erroneously equate the concept of cycloid psychosis with the ATPD from the ICD-10 [18,19].…”

The diagnosis of cycloid psychosis has a long tradition in European psychiatry. However, it has been poorly assimilated within the DSM IV and ICD-10 diagnostic systems. Leonhard set the basis for the current conceptualization of the disorder, and Perris and Brockington developed the first operational diagnostic criteria. However, the two conceptualizations of the disorder are not the same and differ across a number of meaningful variables. Cycloid psychosis is a useful concept in that it possesses both clinical and predictive validity. Despite the high prevalence of mood symptoms and syndromes, cycloid psychosis does not equal schizoaffective disorder. Although a substantial body of evidence suggests that cycloid psychosis differs meaningfully from typical schizophrenia, it is less clear whether it differs from major mood disorders or represents an independent nosological entity. The existence of putative subtypes is also likely, and the differentiation between affective and nonaffective subtypes has received some support.

“…Examples are the 'bouffée délirante' of French psychiatry [18,19], the psychogenic psychoses mainly diagnosed in Scandinavian countries [20], the acute psychotic disorders often seen in developing countries [21], the atypical psychoses of Japanese psychiatry [22] and 'good prognosis schizophrenia' [23].…”

Objective: We prospectively investigated a sample of 42 patients with acute and transient psychotic disorder (ATPD) as defined by the 10th revision of the International Classification of Diseases (ICD-10; F23) to determine the clinical and demographic features of this entity and its relationship to cycloid psychoses. Methods: During a 5-year period, all in-patients with ATPD were identified. We systematically evaluated demographic and clinical features and carried out follow-up investigations on average 2 years after the index episode, using standardised instruments. Results: We found 42 cases of ATPD (4.1%) among 1,036 patients treated for psychotic disorders or a major affective episode. There was a marked female preponderance in ATPD (79%). Fifty-five percent of cases concurrently met the criteria of cycloid psychosis according to Perris and Brockington [in Perris C, Struwe G, Jansson B (eds): Biological Psychiatry. Amsterdam, Elsevier, 1981, pp 447–450]. There was no difference in gender distribution between cycloid and non-cycloid ATPD. As expected, abrupt onset and polymorphic features were significantly more common in cycloid than in non- cycloid ATPD. At follow-up, patients with cycloid ATPD showed less persistent alterations and better social functioning. Conclusion: ATPD as defined by ICD-10 is a heterogeneous category. A diagnosis of cycloid psychosis is made in half of the cases of ATPD, and in these cases, the prognosis is more favourable.

“…Female preponderance in acute psychoses has been observed as a consistent finding across different studies conducted over the past four decades, and even in recent studies using the ICD-10 diagnostic criteria [35,[37][38][39]. This is in stark contrast to schizophrenia, which is observed to have an equal prevalence across genders.…”

“…Although treatment response could be a potential confounder in the study, the findings suggest the probability of two different diagnostic entities-one with a better prognosis and the other with a poor prognosis [37].…”

Section: Duration Of Illnessmentioning

“…If the duration criteria of the current ICD-10 system to diagnose acute and transient psychotic disorder are used, there is a greater likelihood of excluding a large proportion of the conditions for which the grouping of acute and transient psychotic disorder is intended. There is a need to modify the duration of illness criteria for the acute and transient psychotic disorder (at least for some subcategories) in ICD-10, and expand them to approximately 6 months [37,47,56].…”

Concept and nosologic status of acute and transient psychotic disorders, as they appear in the tenth edition of the International Classification of Disease, have seen review from the standpoint of validation and delineation from schizophrenia and affective disorders. Current research, particularly on the epidemiology, course, and outcome, and family genetic studies indicate that these disorders are common among women in developing countries, as well as among lower socioeconomic status and rural subjects. These patients have greater frequency of exposure to stress before childbirth, a family history of acute and transient psychotic disorder (and not of schizophrenia), and a course and outcome that is different from that of schizophrenia. The findings so far support the argument that acute and transient psychotic disorders are different from schizophrenia.

Delineation of Acute and Transient Psychotic Disorders in a Developing Country Setting

Abstract: Acute transient psychoses conform neither with schizophrenia of brief duration nor with atypical affective psychosis, and thus require separate classification as proposed in the ICD-10.
