Cognitive Disengagement Syndrome in Functional Neurological Symptom Disorder

This cross-sectional observational case-control study aims to investigate symptoms of sluggish cognitive tempo (SCT), also known as cognitive disengagement syndrome (CDS), in adults diagnosed with Functional Neurological Symptom Disorder/Conversion Disorder (FNSD/CD). The study compares SCT/CDS symptoms between patients with FNSD/CD and healthy controls and evaluates their relationship with clinical variables. It is hypothesized that individuals diagnosed with FNSD/CD will exhibit higher levels of SCT/CDS symptoms compared to healthy controls.
