Clinical Profile and Induction Protocol of Video Electroencephalography in Children with Functional Neurological Symptom Disorder
摘要
To describe the clinical features and a structure, non-invasive induction protocol performed during video electroencephalography (V-EEG) of children with functional neurological symptom disorder (FNSD).
MethodsThis observational study conducted over 1 year (November 2024–November 2025) enrolled children aged 6–14 years with clinically suspected FNSD. The children underwent V-EEG followed by a stepwise, non-invasive induction protocol. The study assessed the success of event induction, distress during induction, time taken to induce events, and dissociative symptoms using the Childhood Dissociative Checklist (CDC).
ResultsA total of 58 children (39 girls) with FNSD were included. Motor symptoms were the most common presentation (n = 20, 34.5%). Twenty-nine out of 35 children who underwent the induction protocol showed reproducible events during testing. Verbal suggestion focused on psychosocial stressors was the most effective technique in 22 (62.9%) children. CDC scores and distress scores were comparable across the different induction techniques (verbal suggestion, temporal compression, and moist swab application). No adverse effects related to the induction procedure were reported.
ConclusionsThe non-invasive induction protocol used along with V-EEG was safe and useful supportive tool for diagnosing FNSD in children.
