Diffusivity in multiple sclerosis lesions: At the cutting edge?☆
BACKGROUND Radial Diffusivity (RD) has been suggested as a promising biomarker associated with the level of myelination in MS lesions. However, the level of RD within the lesion is affected not only by loss of myelin sheaths, but also by the degree of tissue destruction. This may lead to exaggeration of diffusivity measures, potentially masking the effect of remyelination. OBJECTIVE To test t...
متن کاملNeurogenesis in the chronic lesions of multiple sclerosis
Subcortical white matter in the adult human brain contains a population of interneurons that helps regulate cerebral blood flow. We investigated the fate of these neurons following subcortical white matter demyelination. Immunohistochemistry was used to examine neurons in normal-appearing subcortical white matter and seven acute and 59 chronic demyelinated lesions in brains from nine patients w...
متن کاملIncreased diffusivity in acute multiple sclerosis lesions predicts risk of black hole.
OBJECTIVE Diffusion tensor imaging (DTI) quantifies Brownian motion of water within tissue. Inflammation leads to tissue injury, resulting in increased diffusivity and decreased directionality. We hypothesize that DTI can quantify the damage within acute multiple sclerosis (MS) white matter lesions to predict gadolinium (Gd)-enhancing lesions that will persist 12 months later as T1 hypointensit...
متن کاملThe Effect of Core Stability Exercise Program on the Balance of Patients with Multiple Sclerosis
Background: Multiple sclerosis (MS) is a chronic disease characterized by degradation of the central nervous system myelin which may impair the balance of patients. Core Stability Exercises have been the focus of attention for repairing the stability of some patients. Objectives: To assess the effect of core stability exercise on the balance of patients with multiple sclerosis. ...
متن کاملHypothalamic lesions in multiple sclerosis.
Demyelinating lesions of fiber bundles in and adjacent to the hypothalamus (i.e. the fornix. anterior commissure, internal capsule, and optic system) may be the basis for autonomic and endocrine alterations in multiple sclerosis (MS) patients. Therefore we investigated the presence and immunological activity of lesions in hypothalamic fiber bundles of 17 MS patients and 14 controls. In the MS g...
