Brain atrophy as determined by quantitative MRI can be used to characterize disease progression in multiple sclerosis. Many studies have addressed white matter (WM) alterations leading to atrophy, while changes of the cerebral cortex have been studied to a lesser extent. In vivo, the cerebral cortex has been difficult to study due to its complex structure(More)
The differentiation of multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) from idiopathic Parkinson's disease (IPD) is difficult. Magnetization transfer imaging (MTI), a measure that correlates with myelination and axonal density, was employed in this study in the attempt to distinguish between these disorders. Measurements were carried(More)
BACKGROUND In patients with isolated syndromes that are clinically suggestive of multiple sclerosis, such as optic neuritis or brain-stem or spinal cord syndromes, the presence of lesions as determined by T2-weighted magnetic resonance imaging (MRI) of the brain increases the likelihood that multiple sclerosis will develop. We sought to determine the(More)
Recent clinical studies in multiple sclerosis (MS) provide new data on the treatment of clinically isolated syndromes, on secondary progression, on direct comparison of immunomodulatory treatments and on dosing issues. All these studies have important implications for the optimized care of MS patients. The multiple sclerosis therapy consensus group (MSTCG)(More)
A cross-sectional cost-of-care study was performed to assess the economic burden of multiple sclerosis (MS) in France, Germany and the UK. Patients were stratified into 3 groups according to the Expanded Disability Severity Scale (EDSS): stages I, II and III, corresponding to mild (EDSS 1.0 to 3.5), moderate (EDSS 4.0 to 6.0) and severe (EDSS 6.5 to 8.0)(More)
OBJECTIVE To assess the quality of life (QoL) of patients with multiple sclerosis in France, Germany, and the United Kingdom with a cross sectional study. METHODS Patients were classified into three severity groups according to the expanded disability severity scale (EDSS); stage I, II, and III, corresponding to mild (EDSS 1.0-3.5), moderate (EDSS(More)
Abnormalities of the sarcotubular system presenting as tubular aggregates (TAs) have been described in a variety of neuromuscular disorders. Here, we report on immunohistochemical and biochemical findings in 7 patients (2 familial and 5 sporadic cases) suffering from myopathies with TAs. In muscle biopsy specimens from 5 of the 7 patients, TAs were(More)
Mitochondrial pathology is an early observation in motor neurons and skeletal muscle of patients with amyotrophic lateral sclerosis (ALS). To clarify the relevance of this finding, we determined the effects of a 1-month oral administration of creatine on (1)H NMR-visible metabolites in the motor cortices of 15 controls and 15 patients with sporadic ALS,(More)
The aim of this study was to use neuropsychological data to characterize two subtypes of multiple sclerosis (MS) patients in a large patient sample. We studied patients with primary-progressive MS (PPMS) and secondary-progressive MS (SPMS). A group of 121 MS patients (36 PPS, 85 SPMS) and 40 healthy controls were administered a brief battery of cognitive(More)
In patients with relapsing-remitting multiple sclerosis (MS), IVIG was shown to reduce the relapse rate and progression of disability. In patients with chronic progressive MS, a beneficial effect of IVIG was not documented in placebo controlled studies. This trial investigated the influence of IVIG in primary (PPMS) and secondary (SPMS) chronic progressive(More)
