About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Meeting the diagnostic criteria for FNSD/CD according to DSM-5-TR at the time of admission
Being between 18-65 years of age
Absence of additional psychiatric disorders
Absence of alcohol/substance use disorder
Disqualifiers
Being under 18 or over 65 years of age
Not meeting the diagnostic criteria for FNSD/CD according to DSM-5-TR
Active alcohol/substance use
Having neurological diseases affecting cognitive functions (such as Alzheimer's disease, delirium, Parkinson's disease)
Trial population
The study population will consist of adult participants aged 18-65 years. The Functional Neurological Symptom Disorder (FNSD) group will include consecutive subjects diagnosed with FNSD according to DSM-5-TR criteria who will be admitted to the psychiatry clinic of Elazığ Mental Health and Diseases Hospital (Turkey). The healthy control (HC) group will consist of individuals from the general population who will apply to the hospital medical board and will have no current or past psychiatric or significant medical disorders. All participants will provide informed consent prior to enrollment.

Barkley's Adult Sluggish Cognitive Tempo Ratings Scale -Turkish Version (SCT)
Adult Sluggish Cognitive Tempo Ratings Scale (SCT) was developed by choosing the symptom sets used in prior studies of SCT in children and adolescents. It is a self-report scale and included the following nine items: "1. Prone to daydreaming when I should be concen trating"; "2. I have trouble staying alert or awake in boring situations"; "3. I am easily confused"; "4. I am easily bored"; "5. My mind is spacey or in a fog"; "6. I am lethargic, more tired than others"; "7. I am underactive or have less energy than others"; "8. I am a slow- moving"; "9. I don't seem to process information as quickly or as accurately as others.".Barkley suggested using the number of SCT symptoms answered often or very often as a total score and 5 or higher total score as a cutoff point for having elevated SCT.

Somatoform Dissociation Questionnaire (SDQ-20)
The Somatoform Dissociation Questionnaire is a self-assessment scale which is administered to psychiatric patients, individuals with traumatic experiences, and non-clinical populations for screening purposes. The self-administered scale contains 20 questions, each answered with a scale of 1 to 5 options. Studies in Turkey have reported that individuals with a total score of 40 or higher have a high probability of having a dissociative disorder.

Adult ADHD Self-Report Scale (ASRS)
The Adult Attention-Deficit/Hyperactivity Disorder (ADHD) Self-Report Scale is a 5-point Likert-type scale (0-4 = never, rarely, sometimes, often, very often) to identify current ADHD symptoms. The scale consists 18 items: nine for attention deficit (Items 1,2,3,4,7,8,9,10,11) and nine for hyperactivity/impulsivity (Items 5,6,12,13,14,15,16,17,18). Stepwise regression analysis demonstrated that 6 items of the scale could predict the diagnosis of ADHD better, and these 6 items were listed under section A. Higher scores are associated with higher ADHD severity.
