Demyelinating diseases alter myelin or the coating surrounding most nerve fibers in central and peripheral nervous systems. The grouping of human system demyelinating disorders today includes multiple sclerosis (MS) neuromyelitis optica spectrum (NMOSD) as distinct disease categories. Each is caused by a complex combination genetic environmental variables, many involving an autoimmune response....

to understand the mechanism of multiple sclerosis (ms), an autoimmune demyelinating disease, the researchers developed an experimental animal model for ms, which is called eae (experimental allergic encephalomyelitis). there are several methods for inducing this animal model. in this research the active eae, which is developed by injecting bovine myelin antigens into genetically susceptible ani...

Forty one moderately impaired patients with clinically confirmed multiple sclerosis (MS) and a relapsing-remitting course were submitted to a neuropsychological battery and magnetic resonance imaging (MRI) to correlate the neuropsychological performances with the degree of cerebral demyelination. The neuropsychological results were indicative of a very mild overall impairment. The patients were...

conclusions our findings indicate that fatigue and disability may affect a patient’s quality of life. although mobility may affect the overall quality of life in patients with multiple sclerosis, it may also affect the physical health of ms patients. therefore, the identification of factors affecting the quality of life in ms patients may help in predicting the quality of life, and designing a ...

A 20-year-old man presented with vertigo followed by hourly episodes of dysarthria and incoordination lasting 5–20 seconds (video 1). Neurologic examination was normal between episodes. The only brain/spine MRI lesion in the right superior cerebellar peduncle (figure, A). CSF analysis revealed elevated white blood cells (6/?L [normal, 0–5]) oligoclonal bands (?4). Paroxysmal dysarthria–ataxia a...

Multiple sclerosis, the clinical features and pathological correlate for which were first described by Charcot, is a chronic neuroinflammatory disease with unknown etiology and variable clinical evolution. Although neuroinflammation is a descriptive denominator in multiple sclerosis based on histopathological observations, namely the penetration of leukocytes into the central nervous system, th...

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) which causes demyelination of the nerve fibers. The etiology of this disease is not well understood but it is believed that T helpers play a central role in MS. Numerous findings support the view that Th17 cells play an essential role in pathogenesis of MS and IL-17 secreting T (Th17) cells have a role in infla...

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) characterized by inflammatory and neurodegenerative processes. One of its pathophysiological hallmarks is demyelination, a consequence of oligodendroglial cell death leading supply shortfall and missing electrical insulation to axons. Demyelination induced consequences on neuronal network activity and subsequen...

AIMS To examine the vascular changes occurring in three archival cases of acute multiple sclerosis, and to provide immunohistochemical evidence of early endothelial cell activation and vascular occlusion in this condition. METHODS Central nervous system tissues from three cases of acute active multiple sclerosis and six non-inflammatory controls were stained using the following methods: haema...

Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system. Different trigger pathologies have been suggested by the primary cytodegenerative "inside-out" and primary inflammation-driven "outside-in" hypotheses. Recent data indicate that mitochondrial injury and subsequent energy failure are key factors in the induction of demyelination and neurodegeneratio...
