This study compared the condition of Functional Neurological Disorder (FND) patients with psychosomatic (PSM) patients and post-stroke patients. The results showed that FND and PSM patients scored highly in biopsychosocial complexity and had lower mental and somatic quality of life. These findings emphasize the importance of evaluating FND from a biopsychosocial perspective.
Background: Functional Neurological Disorder (FND) is considered a biopsychosocial disorder nowadays, with chronicity in >50% of cases. The INTERMED Self -Assessment Questionnaire (IMSA) assesses the various domains and indicates biopsychosocial complexity.Objective: FND patients were compared with a sample of psychosomatic (PSM) patients as well as post-stroke patients.Methods: The three samples (N = 287 altogether) were largely in inpatient and day clinic psychotherapeutic treatment or inpatient neurological rehabilitation. The IMSA covers all three biopsychosocial domains as well as health care utilisation in the time frame of the past, the present and the future. In addition, affective burden (GAD-7, PHQ-9), somatoform symptoms (PHQ-15), dissociation (FDS) and quality of life (SF-12) were evaluated.Results: FND and PSM patients scored highly in the IMSA, with & GE;70% regarded as complex, compared to 15% of post-stroke patients. Affective, somatoform and dissociation scores were high in FND and PSM patients. Mental and somatic quality of life were lower in these groups compared to post-stroke patients.Discussion: FND patients showed high biopsychosocial strain, similar to a typical sample of inpatient and day clinic, i.e. severely affected, PSM patients, and they were more affected than post-stroke patients. These data emphasize that FND should be evaluated with a biopsychosocial perspective. The IMSA likely represents a valuable tool, which has to be assessed by further longitudinal studies.
