Abstract
OBJECTIVES
Although early and rapid recognition of a psychotic trend in patients with epilepsy certainly pay dividends, there is no handy assessment instrument for screening because of multiple intrinsic difficulties such as lack of a standard screener as well as a reliability gap for screeners between help-seeking and general populations. On the other hand, the predominance of positive symptoms at the initial stage of psychosis is a promising aspect of this specific group. The following specific questions were examined. Is there a measurable difference between the assessment of the treating doctor and the real feelings of the patient? How well does the attained score correspond to the clinical diagnosis?
METHODS
The self-reported Emotions with Persecutory Delusions Scale (EPDS) questionnaire, previously validated in a general population, was used as the assessment tool for psychotic trend in 79 outpatients with epilepsy. Independent from scoring by the patients, the treating doctors also expressed their impressions about the same patients using the same scoring tool.
RESULTS
Stepwise multiple regression analysis of the EPDS scores of both doctors and patients revealed that a clinical diagnosis of psychosis was the only independent variable significantly related to EPDS score. Also, there was a significant difference between the EPDS scores of the patients and those of the doctors, in favor of the former.
SIGNIFICANCE
Clinical diagnosis of psychosis proved to be the most powerful determinant of EPDS score independent from other clinical factors. The awareness gap between doctors and patients based on EPDS score revealed that treating doctors often clearly underestimate the psychotic trend of their patients. Our findings suggest that such simple tests as EPDS, with a narrow focus on attenuated delusional symptoms, may help screen for an early psychotic episode in patients with epilepsy that may otherwise not be diagnosed by their physicians.
