Differences in self-reported depressive symptoms between patients with epileptic and psychogenic nonepileptic seizures

Abstract Depression is a multidimensional condition encompassing affective, physiological, and cognitive symptoms. Although depression's high comorbidity with both epileptic and psychogenic nonepileptic seizures (ES and PNES) has been established, few studies have addressed whether the types of depressive symptoms experienced differ by seizure type (ES and PNES). This study compared the self-reported depressive symptomatology of patients ( n = 60 ES and 59 PNES) who underwent video-EEG monitoring and completed self-reported objective measures of psychopathology (PAI and BDI-II). Differences in depressive symptoms were also compared by gender and among several subgroups with ES. Results revealed the PNES group, particularly PNES females, endorsed a significantly higher level of physiological symptoms of depression as measured by the PAI DEP-P subscale than the ES group; the BDI-II did not differ between groups. These findings have potential clinical implications for the identification and management of depressive symptoms among these patient groups.
