“…These psychoses share schizophrenic, affective and delirious features in various combinations and constitute a largely unexplored area of psychiatry [5,[16][17][18][19][20][21][22][23]. This is also reflected in the ICD-10 criteria for the acute and transient psychotic disorders (F23), where it is stated that the nosological status of these disorders remains uncertain [3].…”

“…The nosological status of these disorders is controversial, and many researchers claim that they should be included in the existing classifications. In this line of thought, these syndromes have been assigned to various divergent diagnostic categories in the ICD-10 [3,18,21].…”

“…These syndromes are primarily encountered in the traditional societies of developing countries of Asia, Africa and Latin America, but are met in developed countries as well, where they have usually been referred to as 'oneiroid states', 'bouffées délirantes' or brief schizophreniform psychoses [16][17][18][19][20]. The nosological status of these disorders is controversial, and many researchers claim that they should be included in the existing classifications.…”

Functional Psychosis in Middle-Aged People Presenting as a Long-Lasting Confusion State: A Report of Two Cases

et al. 2001

Two cases of functional psychosis in middle-aged people are reported. These patients manifested a long-lasting confusion, which eventually resolved. Attention is drawn to the fact that the clinical presentation of psychosis with predominant confusion symptoms is much more frequently encountered than usually believed. This particular clinical feature has been rather underestimated and only vaguely described in the current diagnostic classification systems. This often results in diagnostic perplexity in everyday psychiatric practice and delays the initiation of appropriate treatment. Finally, these reports are briefly discussed in the context of various proposed nosological entities, and the need for more systematic clinical information that would provide guidance on the classification of such psychotic disorders is suggested.

“…It has also been suggested that certain SPD features sharing a closer genetic relationship to schizophrenia appear more than others and may reflect in an individual's social, cognitive, and attentional deficits (O'Flynn et al 2003). Other impairments appear to be manifested in working memory and verbal learning in those with SPD, rather than generalized intellectual deficits that are observed in schizophrenia (Pull et al 2003).…”

Schizotypal personality disorder (SPD) is characterized by eccentric behavior and perceptual distortions that closely resemble the patterns observed in those with schizophrenia. Schizophrenia and related personality disorders (i.e., SPD) are associated with deficits in sustained attention, slower than normal reaction times, and manifestations of working memory deficits and erratic cognitive tasks. The present study used the schizotypal personality scale (STA) to compare cognitive abilities of self-reported low schizotypic tendency subjects with high schizotypic tendency subjects. The group scores on the STA differed significantly. Those with high STA scores also tended to have higher state and trait anxiety scores based on the State-Trait Anxiety Inventory (STAI). The groups did not significantly differ on any of the demographic variables tested, including age, education, self-rated health status, and medication. Along with an executive function test, two computerized tasks tested subjects on reaction time and memory. Even when covariates (i.e., state, trait anxiety scores) were analyzed, there were no significant differences between the groups and tasks, although the gathered data showed trends in the expected direction.
