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)
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)
Neurocognitive involvement in multiple sclerosis (MS) is heterogeneous with some authors suggesting a frontal pattern in patients with predominantly frontal lesions. To assess the relationship between the distribution of lesions and two cognitive components (visual N2, auditory P3a) of the event-related brain potential (ERP) receiving contributions from(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)
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)
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)
BACKGROUND Detecting malingering or exaggeration of impairments in brain function after traumatic brain injury is of increasing importance in neuropsychological assessment. Lawyers involved in brain injury litigation cases routinely coach their clients how to approach neuropsychological testing to their advantage. Thus, it is important to know how robust(More)
BACKGROUND AND PURPOSE The trend towards a shorter stay in rehabilitation clinic has implications for future language therapy. Constraint-induced aphasia therapy (CIAT) is administered 3 h per day for a total of 30 h of treatment. It was evaluated for patients with chronic aphasia. In the present study we investigated the efficacy of a modified CIAT(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)
