Functional neurological disorder: a comparative analysis of experience of Czech, Slovak, and Italian neurologists.

Abstract

Aim of study: We aimed to compare knowledge, opinions, and clinical experiences among Czech, Slovak, and Italian neurologists to identify potential educational gaps and unify understanding.

Clinical rationale for study: Functional neurological disorder (FND) is a disabling condition characterised by motor, sensory, or cognitive symptoms which are incompatible with other neurological disorders. Novel diagnostic and treatment approaches have improved FND management. However, the extent of their adoption, and any differences or similarities across European communities, remain to be established.

Material and methods: Members of the Czech and Slovak Neurological Societies were invited via e-mail to participate in a 14- -item web-based survey investigating their approach to FND. This data was compared to results from a previous study involving 492 Italian neurologists.

Results: 232 questionnaires were completed by Czech and Slovak neurologists (CZ-SK). Similarities were found between CZ- -SK and Italian neurologists in their preference for the term 'FND' over other psychological-related terms and in explaining symptoms as due to abnormal functioning of the nervous system rather than attributing them to mental illness. However, only fewer than 5% in both groups thought that simulation was highly unlikely. Both groups reported relying on positive signs (e.g. inconsistency, distractibility) according to the current diagnostic criteria, but also a tendency to perform additional tests to exclude other causes. However, some differences were observed: Italian neurologists placed a greater emphasis on psychological factors including litigation. CZ-SK neurologists were more likely to suggest physiotherapy as a treatment option and to provide educational intervention for patients and their relatives.

Conclusions: Overall, our findings suggest that although Czech, Slovak, and Italian neurologists have adopted some new developments in the field of FND, significant gaps still exist in their understanding and common practices regarding conceptualisation, diagnosis, and treatment.

Clinical implications: Our results suggest that promoting knowledge through postgraduate curricula and teaching courses for neurologists is necessary to optimise patient management in various European countries.
