Acute and transient psychotic disordrs disordeers : demographic and clinical attribute

Abstract EN

Background: The ICD-10's Acute and Transient Psychotic Disorders (ATPD) include all psychotic conditions of acute onset and short duration (less than one month), not attributable to organic or substance-related problems and not meeting the diagnostic criteria of a mood disorder.

The present study aims to estimate the treated prevalence of ATPD among psychiatric inpatients and to identify its distinguishing clinico-demographic features.

Method: AH consecutive ATPD patients admitted to the psychiatric ward of King Fahd Hospital at the University, Al-Khobar, Saudi Arabia over 14 years (1988-2002) constituted the study group.

A control group of an equal size, matched for sex and age, was randomly drawn from all the other psychiatric patients admitted during the same period.

The sociodemographic and clinical features of the two groups were compared.

Results: ATPD was diagnosed in 148 (7.3 percent) of a total of 2024 patients, and in 14.1 percent of the 1047 patients presenting with psychotic symptoms.

Compared to the matched control group, the ATPD patients were significantly more frequently Asian expatriates, unskilled workers recently immigrating, unaccompanied by their families, living with work-mates or employers.

In the overwhelming majority (89.2 percent) of cases ATPD arose following identifiable stressful life events.

In most cases the presenting symptoms completely disappeared within the first week of admission.

Conclusions: The bulk of ATPD cases seem to be psychogenic reactions to upsetting psychosocial stressors in a background of inadequate social support.

The diagnostic, therapeutic and preventive implications of these findings are discussed
