Filter by:Patients with multiple sclerosis (MS) may show chronic signs of optic neuropathy (CON) that may follow acute optic neuritis (secondary form of CON, S-CON) or occur independently of any acute demyelinating lesion of the optic nerve (primary form of CON, P-CON). In both S-CON and P-CON, a long term progressive ganglion cell axonal loss occurs. This axonal damage could be secondary to retrograde atrophy of axons within plaques of demyelination or a primary progressive degeneration of ganglion cells, but the underlying physiopathology has not been fully questioned in the different profile types of CON. In this project, investigators aim at understanding the pathophysiology of S-CON and P-CON, i.e. secondary to demyelination or primary degeneration, in patients complaining of persistent visual complaints. In a first cross sectional study, 30 MS patients with mild to moderate P-CPON or S-CON and 30 age-matched control subjects will perform an extensive neuro-ophthalmological assessment including clinical examination, visual evoked potentials (pattern and low contrast), electroretinogram (pattern and multifocal ERG), OCT (peripapillary and macular volume scan segmentation protocols) and MRI of the optic nerve. In these patients with mild to moderate CON, investigators aim at differentiating patients showing predominant demyelination from those showing pure or predominant axonal degeneration. Visual function assessment and degree of axonal degeneration will be compared and correlated in the two types of underlying pathophysiology and in the group of control subject. In a following longitudinal study, the patients will be re-assessed a year later in order to evaluate the progression of CON in both profile types. Our hypothesis would be that visual function and progression is worse in the degeneration group as compared to the demyelination group. This study should help to find reliable measures of the pathophysiology of CON and correlate it with the long-term visual prognostic of the disease.
Phase II a Proof of concept study in Multiple Sclerosis (MS) patients with spasticity.
This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities in individuals with multiple sclerosis (MS) or encephalitis. Participants will be asked to come in daily for two full weeks during which time participants will undergo cognitive testing and Magnetic Resonance Imaging (MRI) brain scans. In this research, a very weak electrical current is administered to the surface of the scalp while participants complete cognitive tasks. The investigators' aim is to find out whether tDCS will improve task performance in adults with multiple sclerosis or encephalitis.
This study will examine the effectiveness of two types of group exercise classes on the health and functional status in inactive adults age 18-65 with neurological conditions including Multiple Sclerosis, stroke, and spinal cord injury (SCI). Participants will be randomly assigned to one of three groups; Movement to Music, Adapted Yoga, or a waitlist group who will complete a home-based exercise intervention of either Movement to Music or Adapted Yoga.
The primary objective of the study is to evaluate the effect of BG00012 on lymphocyte subset counts during the first year of treatment in subjects with relapsing-remitting multiple sclerosis (RRMS). A secondary objective is to evaluate the pharmacodynamic effect on absolute lymphocyte counts (ALCs) and immunoglobulins (Igs) during the first year of treatment.
Outcomes from the investigators' recent investigation suggested that a high dosage of challenging physical therapy exercises can result in clinically improvements in the postural balance and walking speed of individuals with MS. This investigation will evaluate mobility and postural balance improvements in individuals with MS who participate in a therapeutic protocol consisting of activity based exercises, and in individuals with MS that participate in challenging physical therapy protocol.
Depression and anxiety are common in MS and often go untreated. Even symptoms which do not meet the threshold for a psychiatric diagnosis can have a significant impact on quality of life. Positive Mental Training (PosMT) is a 12 week programme which aims to help people overcome the negative thinking and feelings that come with worry and low mood and become more positive, confident and resilient. To find out if Positive Mental Training is helpful in MS the investigators are running a randomised controlled trial. The initial study is a pilot tiral, the primary function being examination of the feasibility and acceptability of this treatment in MS. Though sample size is small and consequently it may not be powered to detect a significant change in symptoms in association with the treatment, this will also be examined.
Multiple sclerosis (MS) is an inflammatory disease of the central nervous system, beginning most often in subjects aged 20-40 years. In France, thanks to recent studies reported during general states of MS in 2006, the prevalence is estimated at 65.5 / 100,000 population (96.3 / 100,000 women and 41.9 / 100,000 men) and incidence at 7.91 per 100,000. In Lower Normandy, the incidence of MS is estimated to 4.45 / 100,000 inhabitants or 60 new cases per year. The primary objective of this pilot study is to assess the levels of glutamate and aspartate (excitotoxicity markers) and their repercussions on the clinical and radiological outcome in 40 patients experiencing an event demyelinating central nervous system.
The primary objective of the study is to assess the pharmacokinetic (PK) profile of BIIB061 in the new oral formulation in the fasted state in healthy male and female volunteers. The secondary objective of this study is to evaluate the safety and tolerability of BIIB061 in the new formulation in this study population.
The primary objective of the study is to retrospectively investigate changes in lymphocyte counts and lymphocyte subtypes, with a focus on CD4+ and CD8+ T cells, in participants on Tecfidera therapy for at least 6 months. The secondary objective is to investigate changes in lymphocyte subtypes other than CD4+ and CD8+ T cells.
