Acute multiple sclerosis lesion pathology does not predict subsequent clinical course —a biopsy study

ConclusionUniform white matter subacute demyelination is associated with a diverse clinical course ranging from a monophasic illness to progressive MS, suggesting that extraneous factors distinct from the basic pathology significantly influence the clinical course in MS.

However, inconsistent results have been reported regarding the correlation of CSCA and clinical disability in multiple sclerosis (MS). The aim of this meta-analysis was to synthesize the available data obtained from 3.0-Tesla (3T) MRI scanner...

ConclusionThis is the first Egyptian study to show that infratentorial lesions, confluent brain lesions and T1 hypointense lesions are conventional MRI parameters that correlate with the degree of disability in Egyptian MS patients.

ConclusionWe found no indication of a prognostic value of WML shrinking in early MS patients. WML shrinking seems to be related to waning of acute inflammation.

AbstractChronic active and slowly expanding lesions with smouldering inflammation are neuropathological correlates of progressive multiple sclerosis pathology. T1 hypointense volume and signal intensity on T1-weighted MRI reflect brain tissue damage that may develop within newly formed acute focal inflammatory lesions or in chronic pre-existing lesions without signs of acute inflammation. Using a recently developed method to identify slowly expanding/evolving lesionsin vivo from longitudinal conventional T2- and T1-weighted brain MRI scans, we measured the relative amount of chronic lesion activity as measured by change in...

The objective of this study was to compare the efficacy of fingolimod and teriflunomide in reducing disease activity in RRMS.MethodsThis multicenter, retrospective observational study was carried out with prospectively collected data from 15 centers. All consecutive RRMS patients treated with teriflunomide or fingolimod were included. Data for relapses, Expanded Disability Status Scale (EDSS) scores and brain magnetic resonance imaging (MRI) scans were collected. Patients were matched using propensity scores.Annualized relapse rates (ARR), disability accumulation, percentage of patients with active MRI and treatment discon...

AbstractStudies comparing the effects of natalizumab and fingolimod in relapsing –remitting multiple sclerosis (RRMS) are limited. We aimed to compare natalizumab and fingolimod effects on clinical, neuropsychological, and MRI measures in RRMS patients after 2 years of treatment. RRMS patients starting natalizumab (n = 30) or fingolimod (n = 25) underwent neurologic, neuropsychological, and brain MRI assessments at baseline, month (M) 6, M12, and M24. Volumes of lesions, brain, gray matter (GM), white matter (WM), and deep GM were measured. Fifteen healthy controls (HC) were also scan...

Multiple Sclerosis (MS) can be prevented by undergoing routine magnetic resonance imaging (MRI) tests, according to researchers from the Institute of Neurology in London. MS progression is difficult to predict as the disease manifests itself differently in every patient. In their study recently published in  Brain, the researchers ventured out to define the predictors of long-term disability outcomes by using clinically isolated syndrome (CIS), a first episode of neurological symptoms that can evolve into MS, as a baseline. They used MRI exams after a CIS diagnosis to anticipate the future of a patient ’s h...

CONCLUSIONS: Previous linear, but not macrocyclic, gadolinium-based contrast agent administration is associated with higher relaxation rates in a dose-dependent manner. Higher relaxation in some regions is associated with cognitive impairment but not physical disability or fatigue in MS. The findings should be interpreted with care but encourage studies into gadolinium retention and cognition.

AbstractThe clinical course of relapse-onset multiple sclerosis is highly variable. Demographic factors, clinical features and global brain T2 lesion load have limited value in counselling individual patients. We investigated early MRI predictors of key long-term outcomes including secondary progressive multiple sclerosis, physical disability and cognitive performance, 15 years after a clinically isolated syndrome. A cohort of patients with clinically isolated syndrome (n =178) was prospectively recruited within 3 months of clinical disease onset and studied with MRI scans of the brain and spinal cord at study entry (basel...
