The Complexity of the Diagnostic Pathway of Children With a Functional Neurological Symptomatology Disorder

Conversion Disorder (CD) or Functional Neurological Symptomatology Disorder (FNSD) is a pathology characterized by the occurrence of non-simulated physical symptoms of neurological appearance in the absence of underlying organic pathology. The hyperspecialization of medicine makes the therapeutic approach to FNSD very complex for several reasons: * Pediatric health professionals are trained to diagnose and treat physical disorders and are at a loss when it comes to psychological disorders * Physicians often increase the number of complementary tests before making a diagnosis of FNSD, for fear of missing a serious or urgent pathology * Psychiatric diagnosis is a diagnosis of exclusion, and TSNF is therefore often evoked at the end of the treatment, which leads to wandering in the patient's care This delay in diagnosis does not allow patients to receive appropriate care and the consequences can be serious. The objective of this mixed qualitative and quantitative study is to study the complexity of the care pathway of patients aged 6 to 18 years with a diagnosis of TSNF, as well as their parents and the health professionals who have taken care of them. The collection of their experience will be done by means of semi-structured interviews which will then be analyzed according to the Interpretative Phenomenological Analysis.
