“…Although symptoms seem to be less severe in BPD than in schizophrenia and/or schizophreniform disorder [62], cognitive impairment is common to psychotic disorders [63,76]. BPD patients, however, improved more rapidly, particularly in processing speed, than those with schizophrenia, schizophreniform disorder and/or unspecified psychotic disorder over six months [77].…”

Since the early 20th century, a group of non-affective psychoses with acute onset and brief duration have been described in different countries and under various names, including cycloid psychosis, bouffée délirante, and reactive psychosis. These psychoses share a number of characteristics, including benign course, greater prevalence in women than men and in developing countries than industrialized countries, and high prevalence of premorbid psychological and physiological stressors. However, the variations in names and minute details of symptomatology have overshadowed the basic similarities across these various descriptions. Confusion in classification persists in the two contemporary diagnostic systems, the DSM-IV and the ICD-10. We believe that most cases of these psychoses could be captured under a broad, unified category of non-affective psychosis with acute onset and brief duration, and urge the authors of the upcoming revisions of the DSM and ICD to create such a category. A unified diagnostic category for these disorders would reduce unnecessary fragmentation in the diagnostic systems and assist in the progress of research on these rare conditions.

“…In low- and middle-income countries (countries with a gross national income of less than $5101 https://data.worldbank.org/income-level/low-and-middle-income ) there is a growing literature on neuropsychological measures for psychotic disorders ( Araújo et al, 2015 ; Ayres et al, 2007 ; Nakasujja et al, 2012b ; Ngoma et al, 2010 ). Such work has been useful in demonstrating the large burden of impairment and its association with poor outcomes ( Ayres et al, 2007 ).…”

Introduction Several studies of neuropsychological measures have been undertaken in patients with psychotic disorders from low- and middle-income countries (LMICs). It is, however, unclear if the measures used in these studies are appropriate for cognitive screening in clinical settings. We undertook a systematic review to determine if measures investigated in research on psychotic disorders in LMICs meet the clinical utility criteria proposed by The Working Group on Screening and Assessment. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses were employed. We determined if tests had been validated against a comprehensive test battery, the duration and scope of the tests, the personnel administering the tests, and the means of administration. Results A total of 31 articles were included in the review, of which 11 were from Africa. The studies included 3254 participants with psychosis and 1331 controls. 3 studies reported on the validation of the test against a comprehensive cognitive battery. Assessments took 1 h or less to administer in 6/31 studies. The average number of cognitive domains assessed was four. Nonspecialized staff were used in only 3/31 studies, and most studies used pen and paper tests (17/31). Conclusion Neuropsychological measures used in research on psychotic disorders in LMICs typically do not meet the Working Group on Screening and Assessment clinical utility criteria for cognitive screening. Measures that have been validated in high-income countries but not in LMICs that do meet these criteria, such as the Brief Assessment of Cognition in Schizophrenia, therefore deserve further study in LMIC settings.
