A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This cross‑sectional, case‑control study compares SCT/CDS symptoms in adults with Functional Neurological Symptom Disorder to healthy controls. Researchers will relate SCT/CDS symptoms to clinical features within the FNSD group. The design aims to identify whether SCT/CDS is more prevalent in FNSD/CD and how it correlates with functional impairment or other clinical variables. The study is observational and does not involve an intervention. Participants are adults aged 18–65, with specific exclusion criteria to reduce confounding.
