Functional Neurological Disorders and Functional Dissociative Seizures: Bridging Neurological Insights and Psychiatric Care

Functional Neurological Disorders (FND) and Functional Dissociative Seizures (FDS) represent a complex intersection between the fields of neurology and psychiatry. Historically, FDS were referred to as psychogenic non-epileptic seizures (PNES), a term that has been used for the past three decades to describe seizures with a psychogenic origin, confirmed as non-epileptic through Video-Electroencephalogram (VEEG) monitoring. Despite their prevalence in epilepsy centers, FDS are not caused by the electrical disturbances typical of epileptic seizures, highlighting a significant gap in understanding their pathophysiology and treatment. Recent studies have identified a strong correlation between FDS and trauma, post-traumatic stress, and other psychiatric conditions, suggesting these as key etiopathogenic factors. However, FDS remain underdiagnosed and underestimated in various regions, underscoring the need for improved diagnostic and therapeutic strategies. The integration of psychological and psychiatric assessments in epilepsy centers has begun to shed light on the mental health aspects of FDS, yet there remains a pressing need for further research to refine treatment approaches and improve patient outcomes.

This Research Topic aims to provide a comprehensive review of Functional Dissociative Seizures, fostering a deeper understanding among neurologists, psychiatrists, and psychologists. By bridging neurological insights with psychiatric care, this Research Topic seeks to address the multifaceted nature of FDS. Key objectives include exploring the pathophysiology of FDS, examining the role of trauma and psychiatric conditions in their development, and evaluating current and potential treatment strategies. The Research Topic will also aim to answer critical questions regarding the under diagnosis of FDS and the effectiveness of integrated care models.

To gather further insights into the complex interplay between neurological and psychiatric factors in FDS, we welcome articles addressing, but not limited to, the following themes:

- The historical evolution and current classification of Functional Dissociative Seizures.
- The role of trauma and post-traumatic stress in the development of FDS.
- Advances in diagnostic techniques, including the use of VEEG in epilepsy centers.
- The impact of psychiatric comorbidities on the presentation and management of FDS.
- Integrated treatment approaches combining neurological and psychiatric care.
- Regional disparities in the diagnosis and treatment of FDS.
- Case studies highlighting successful management strategies for FDS patients.
