This study aimed to describe the disease course of psychogenic nonepileptic seizures (PNES) over a prolonged period of time and identify distinguishing features among participants. The findings showed a decrease in seizure frequency over time, but participants still faced significant limitations in their functional level and health-related quality of life. Improved treatment approaches are needed to address these issues.
Background: The disease course of psychogenic nonepileptic seizures (PNES) over a prolonged period of time remains unclear. The aims of the study were: 1. to describe the course of illness with a median follow-up time of 4 years and a range of 2-15 years; and 2. to identify distinguishing features between participants regarding seizure cessation, functional level and health-related quality of life. Methods: Formerly, inpatients of an epileptic ward diagnosed with PNES between 2000 and 2013 were contacted via mail. They were asked by questionnaire about illness characteristics, i.e., age at onset, PNES status at onset and in the course, treatments, psychosocial situation, and quality of life status.Results: Two-thirds of the N = 63 formerly inpatients were female, their age at onset was 26.7 years. Seizure frequency decreased significantly over time, 31.7% were currently seizure-free, but still only 37% were regularly employed. Only 48% had a satisfying health-related quality of life. The remitted participants had a shorter duration of illness and higher health-related quality of life. Participants with a good level of functioning were more likely to be male, took fewer medications, and had a higher health-related quality of life. Those participants with higher quality of life were more frequently employed and had fewer seizures.Conclusions: As participants continue to be severely limited in their functional level and quality of life over the period under review, enhanced treatment approaches that address experiential avoidance seem to be needed.(c) 2023 The Author(s).
