Filter by:Progressive-onset multiple sclerosis (PPMS) occurs in about 15% of all people living with MS. PPMS remains understudied, and most disease-modifying treatments are ineffective for PPMS. To date, it is unknown why some people progress immediately from MS onset. The present study will assess the role of gray matter in PPMS by characterizing it with ultra-high field magnetic resonance imaging (MRI). While both white and gray matter are affected in relapsing MS, in PPMS tissue damage is primarily in the cortex. Cortical gray matter consists largely of neuronal cell bodies, which send electrical signals to create a functional response, such as arm or leg movement. While white matter damage slows the signal response, cortical damage inhibits the initial creation of electrical signals. There is a great need to research and develop scientific biomarkers to identify and monitor progression and repair in PPMS. In this project, 7 Tesla MRI is used to investigate the cortical gray matter in people with PPMS. 7 Tesla MRI is the safest and most detailed way to study the brain. Because the cortex is only a few millimeters thick, it has been traditionally difficult to investigate. At 7 Tesla, different layers and lesions within the cortex can be seen. In addition, this project will use myelin-sensitive MRI to determine the biological underpinnings of both cortical lesions and the 'normal appearing' cortical damage in PPMS. This will answer relevant questions about the brain's capacity for repair, the extent of demyelination and the occurrence of inherent cortical remyelination and provides an avenue for the development of novel clinical MR biomarkers tailored to PPMS.
The study seeks to investigate whether 24 weeks of power training has neuroprotective effects in older PwMS. Additional purposes are to examine the effects of 24 weeks power training on physical function, cognitive function and neuromuscular function. Further, it is investigated whether the potential effects of power training are maintained after 24 weeks of follow-up.
To evaluate the safety and tolerability of OCS-05 compared to placebo in patients with acute optic neuritis (AON) receiving the standard of care
Our overall objective is to obtain an initial assessment of the potential value of using [18F]3F4AP for imaging demyelinating diseases such as multiple sclerosis: - Aim 1) Assess the safety of [18F]3F4AP in healthy volunteers and subjects with multiple sclerosis (MS). Hypothesis 1: Administration of [18F]3F4AP will result in no changes in vitals or other adverse events. - Aim 2) Assess the pharmacokinetics of a bolus infusion of [18F]3F4AP in humans including healthy volunteers and MS patients. Hypothesis 2: the pharmacokinetics of [18F]3F4AP at the whole brain level will be similar in controls and MS subjects. The kinetics in demyelinated lesions will be slower than in healthy control areas. - Aim 3) Assess the reproducibility of [18F]3F4AP in humans. Hypothesis 3: the test/retest variability of [18F]3F4AP within the same subject will be lower than 10%. - Aim 4) Correlate MR brain images with [18F]3F4AP PET brain images. Hypothesis 4A: all the lesions seen on the MRI will show increased signal (VT or SUV) on the PET images. Hypothesis 4B: some of the lesions on the MRI will show increased signal (VT or SUV) on the PET but not all. - Aim 5) Correlate [18F]3F4AP PET signal with neuropsychological testing in people with MS. Hypothesis 5: increased PET signal (VT or SUV) will correlate with impaired Single Digit Modality Test (SDMT) scores. - Aim 6) Correlate [18F]3F4AP PET signal with EDSS score in people with MS. Hypothesis 6: increased PET signal (VT or SUV) will correlate with higher EDSS scores.
To compare between intermittent bolus and traditional continuous drip of 3%NaCl in patients with severe symptomatic hyponatremia in Rajavithi Hospital.
This is a clinical trial to determine the feasibility of a stationary aerobic cycling intervention and explore if aerobic exercise independently promotes remyelination in people with multiple sclerosis (MS).
This study will provide further insights into the natural course of Inflammatory demyelination disease including clinical features，progression, related antibody spectrum and drug treatment effect
This is a longitudinal single blind randomized trial to test the effects of high compared to low dose vitamin D3 supplementation on cognitive performance at 6 and 12 months, and MRI measures of 12 months duration. A cognitive assessment battery will be administered at baseline, 6 and 12 months. Related clinical data and information on depression and anxiety, lifestyle, and food sources of vitamin D and sun exposure among other variables will also be collected.
The purpose of this study is to determine whether intravenous immunoglobulin (IVIg) is an effective intervention for patients with diabetes, peripheral neuropathy, and demyelination on nerve conduction studies. All patients will receive both IVIg and placebo for 3 months each, with a 3 month washout period in between.
This is a prospective, non-randomised, non-blinded, single center study of children and adolescents with multiple sclerosis and clinically isolated syndrome to detect differences or early changes in diffusion-weighted imaging (DTI) by magnetic resonance imaging (MRI).
