OBJECTIVES: I. Determine by quantitative magnetic resonance imaging measurements the change in the total volume of brain parenchyma as well as its gray and white matter, T2 and enhanced T1 lesion volume, and the magnetization transfer ratio histogram parameters, and correlate these measurements with clinical measures of disability in patients with multiple sclerosis.
II. Measure the quantity of whole brain N-acetylaspartate in patients with multiple sclerosis and compare these values to those from age matched controls.
III. Determine the correlation between specific neuropsychological tests which assess global cognitive functioning and the quantitative measurements taken in these patients in this study.
Patients undergo magnetic resonance imaging and spectroscopy with standard gadolinium contrast followed by neuropsychological testing every 6 months for 5 years. An equal number of age and sex matched healthy patients act as a control group and undergo magnetic resonance imaging and spectroscopy without standard gadolinium contrast every 6 months for 5 years.

Several recent studies have shown an increase in the signal intensity of the unenhanced T1-weighted magnetic resonance images in the brain of patients with normal renal functions and a bre...
Gadolinium contrast agents are frequently administered for MRI imaging. Very little is known of its toxicity outside of patients with reduced renal function.
Background: - Contrast agents help things show up better on magnetic resonance imaging (MRI) scans. Researchers want to see if the drug ferumoxytol is a good contrast agent. They want to ...
This study will examine the safety and effectiveness of Zenapax (a laboratory-manufactured antibody) in treating multiple sclerosis. Multiple sclerosis may be caused by an abnormal immune...
The study is being conducted to gain knowledge about a new dose of a diagnostic drug that is used for contrast-enhanced Magnetic Resonance Imaging (MRI) of the human central nervous system...
Gadolinium is a contrast agent that is used in MRI. There is new evidence that gadolinium accumulates in a patient's body and the effects of this accumulation is unknown. This has resulted in differen...
Assessment of health literacy among patients with multiple sclerosis can be used in education planning, disease management, compliance, and quality of life. In addition, health literacy can be assesse...
Multiple sclerosis is a disorder of the central and peripheral nervous system of young and old adults that is characterized by muscle, coordination and vision abnormalities. Multiple sclerosis is like...
A phase II baseline versus treatment study to determine the efficacy of raltegravir (Isentress) in preventing progression of relapsing remitting multiple sclerosis as determined by gadolinium-enhanced MRI: The INSPIRE study.
Although the aetiology of multiple sclerosis (MS) remains elusive, it is clear that Epstein Barr virus (EBV) and possibly other viruses play a role in the pathogenesis of MS. Laboratory evidence sugge...
To investigate, if and how omitting gadolinium-based contrast agents (GBCA) and dynamic contrast-enhanced imaging (DCE) influences diagnostic accuracy and tumor detection rates of prostate MRI.
A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form.

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.
An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)
Gadolinium. An element of the rare earth family of metals. It has the atomic symbol Gd, atomic number 64, and atomic weight 157.25. Its oxide is used in the control rods of some nuclear reactors.
The most common clinical variant of MULTIPLE SCLEROSIS, characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. Common clinical manifestations include loss of visual (see OPTIC NEURITIS), motor, sensory, or bladder function. Acute episodes of demyelination may occur at any site in the central nervous system, and commonly involve the optic nerves, spinal cord, brain stem, and cerebellum. (Adams et al., Principles of Neurology, 6th ed, pp903-914)
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
