Serum Neurofilaments and GFAP in Atypical Multiple Sclerosis

Serum Neurofilaments Light Chain and GFAP (Glial Fibrillary Acidic Protein) in Atypical Idiopathic Inflammatory Demyelinating Disorders

Idiopathic inflammatory disorders of the central nervous system include various disorders of which multiple sclerosis is the most common. Besides multiple sclerosis, other distinct disorders including for example anti-AQP4 (aquaporine-4) and anti-MOG (Myelin oligodendrocyte glycoprotein) NMOSD (Neuromyelitis optica spectrum disorder) have been well characterized and are now known to be distinct from MS. some patient belonging to MS spectrum have recently being characterized but unusual MRI findings have mimicking inherited leukoencephalopathies and leukodystrophies. Whether these patients with atypical phenotype represent a separate disease distinct from MS or belong to MS spectrum is not clear. The objectives are to evaluate a series of 15 patients with atypical forms of MS using non-conventional MRI techniques and biological biomarkers (serum neurofilaments light chain) and to compare them with classical MS patients (15 relapsing remitting patients and 15 progressive patients) and 15 controls. the hypothesize is that these patients with atypical MS have a more severe neurodegenerative process.
