The etiology of multiple sclerosis is an elusive field due to the lack of the usual cause-effect relationship model to explain a disease. In fact, with all the current evidence we start thinking in multiple sclerosis as a multi-factorial disease, where an infective agent on a genetically permissive host can lead to inflammation, demyelination and ultimately to neurological damage with dire cons...

Analyzing lipid composition and distribution within the brain is important to study white matter pathologies that present focal demyelination lesions, such as multiple sclerosis. Some lesions can endogenously re-form myelin sheaths. Therapies aim to enhance this repair process in order to reduce neurodegeneration and disability progression in patients. In this context, a lipidomic analysis prov...

MRI examination of 41 patients with clinical definite multiple sclerosis showed white matter lesions of high proton T2 signal consistent with demyelination in 76% and CSF abnormalities present in 76%. Of patients with CSF abnormalities, 26% had normal MRI scans; conversely 26% of patients with MRI abnormalities had negative CSF studies. Thus a significant number of multiple sclerosis patients h...

Introduction: Consumption of vitamin D3 is effective to reduce intensity of autoimmune diseases such as multiple sclerosis. Neurons of the central nervous system are constantly exposed to reactive oxygen species and these factors play a key role in the destruction of myelin and damage of axons. The hippocampus is a vital center for learning and memory in central nervous system. This area is ...

BACKGROUND Radiation of the central nervous system in patients with demyelinating disease may have deleterious effects. OBJECTIVE To describe a 30-year-old woman with multiple sclerosis who developed an attack of demyelination 2 months following radiotherapy for a parotid malignancy. RESULTS Magnetic resonance imaging demonstrated new hyperintense lesions that corresponded to both the local...

BACKGROUND Primary central nervous system lymphoma (PCNSL) may rarely be preceded by "sentinel demyelination," a pathologic entity characterized by histologically confirmed demyelinating inflammatory brain lesions that mimic multiple sclerosis (MS) or acute disseminated encephalomyelitis (ADEM). Interpreting the overlapping radiologic and clinical characteristics associated with each of these c...

A patient with multiple sclerosis developed a useless, deafferented left hand, as described previously by Oppenheim. Magnetic resonance imaging demonstrates that this is caused by an ipsilateral plaque of demyelination in the posterior columns of the cervical cord.

Myelin basic protein (MBP) is a major component of the myelin sheath of both the central and peripheral nervous systems. A number of neurological diseases in humans are associated with demyelination of the central and/or peripheral nervous systems, including multiple sclerosis and its variants such as acute disseminated encephalomyelitis (AD), acute hemorrhagic leukoencephalopathy, and idiopath...

We have identified a novel serine protease, myelencephalon-specific protease (MSP), which is preferentially expressed in the adult CNS, and therein, is abundant in both neurones and oligodendroglia. To determine the potential activity of MSP in CNS demyelination, we examined its expression in multiple sclerosis lesions and in two animal models of multiple sclerosis: Theiler's murine encephalomy...
