Risk Factors in Cause and Course of Multiple Sclerosis

Multiple sclerosis (MS) is a leading non-traumatic cause of disability in young adults. It is a chronic neurological disorder characterized primarily by central nervous system (CNS) inflammation, myelin loss, and axonal pathology, resulting in progressive neurological dysfunction. Initially, inflammation is transient and partial remyelination occurs. MS is presumed to be an autoimmune disorder arising from complex interactions of both environmental and genetic factors

Fatigue after a first attack of suspected multiple sclerosis

Background: Fatigue is reported by more than 75% of multiple sclerosis (MS) patients. In an earlier study, we showed that fatigue is not only a common symptom in patien

High neurofilament levels are associated with clinically definite multiple sclerosis in children and adults with clinically isolated syndrome

__Background:__ A promising biomarker for axonal damage early in the disease course of multiple sclerosis (MS) is neurofilament light chain (NfL). It is unknown whether NfL has the same predictive value for MS diagnosis in children as in adults. __Objective:__ To explore the predictive value of NfL levels in cerebrospinal fluid (CSF) for MS diagnosis in paediatric and adult clinically isolated syndrome (CIS) patients. Methods: A total of 88 adult and 65 paediatric patients with a first attack of demyelination were included and followed (mean follow up-time in adults: 62.8 months (standard deviation (SD) ±38.7 months) and 43.8 months (SD ±27.1 months) in children). Thirty control patients were also included. Lumbar puncture was done within 6 months after onset of symptoms. NfL was determined in CSF using enzyme-linked immunosorbent assay (ELISA). COX regression analyses were used to calculate hazard ratios (HR) for clinically definite multiple sclerosis (CDMS) diagnosis. __Results:__ After adjustments for age, oligoclonal bands (OCB), and asymptomatic T2 lesions on baseline magnetic resonance imaging (MRI), increased NfL levels in both paediatric and adult CIS patients were associated with a sh
