About this Research Topic
Functional Dissociative Seizures (FDS) are categorized by the DSM-5 as a subtype of Functional Neurological Disorder. Rooted in Pierre Janet's concept of dissociation, they have recently re-emerged in the scientific literature to replace the term psychogenic non-epileptic seizures (PNES), a clinical construct used for the past 30 years to define patients experiencing seizures that were determined to be non-epileptic via VEEG (Video-Electroencephalogram) and with a psychogenic origin. These patients are extensively observed and described in most epilepsy centers that apply VEEG monitoring, however as they are not caused by the same electrical mechanisms that underlie epileptic seizures, there is a need to further examine functional dissociative seizures to understand their pathophysiology and treatment options.
According to most studies, a high prevalence of trauma and post-traumatic stress is frequently present in patients with FDS, as well as underlying psychiatric conditions. This has been considered a main etiopathogenic factor of dissociative conditions. FDS are probably underestimated and underdiagnosed in different geographic areas, however the implementation of psychological and psychiatric assessment of patients presenting with FDS in epilepsy centers has allowed us to better study these patients and to characterize the mental health aspects underlying their FDS. This better directs treatment options for the patient.
This Research Topic aims to offer a comprehensive review of this topic, contributing to a deeper understanding of FDS by not only enhancing knowledge among neurologists, but also among psychiatrists and psychologists who ultimately treat these patients.
