Active clinical trials for "Sclerosis"

The purpose of this database study is to assess if Arepanrix™ vaccination during the 2009 pandemic was associated with an increased risk of multiple sclerosis (MS) in Manitoba, Canada.

The purpose of this study is to look for abnormal genes and gene expression profiles that help determine why a person develops amyotrophic lateral sclerosis (ALS) and related motor neuron diseases (MND) and why their symptoms present and progress with a particular pattern.

Background: - Magnetic resonance imaging (MRI) has been used for decades to help diagnose and monitor neurological disorders like multiple sclerosis (MS). Researchers want to improve how MRI pictures are taken. They also want to learn more about using newer MRIs with stronger magnets to get better pictures than standard MRIs provide. Objectives: - To collect data that will help researchers better understand MS and related diseases. Eligibility: Adults 18 and older with MS or MRI findings that appear similar to MS, or with other neurological diseases that may look or act like MS. Healthy adult volunteers. Design: Participants will be screened with a review of their medical records. Participants will have a baseline visit. It will include a physical exam, medical history, and neurological exam. They may have blood tests. The study will last indefinitely. Participants may have MRIs. Some MRIs may include a contrast dye. For this, a needle will be used to guide a thin plastic tube into an arm vein. Participants may have up to 2 lumbar punctures per year. Skin will be numbed and a needle inserted between back bones will remove fluid. Participants may give saliva samples and have an eye exam. Participants may have evoked potential tests. These measure how the nervous system responds to different types of stimulation. Participants may sit in front of a TV and watch pictures on the screen. Or they may wear earphones that make a clicking noise or static. Or they may get a small electrical shock that may tingle and cause a hand or foot twitch. Participants may have tests of strength, spasticity, sensations, balance, and/or walking.

MicroRNAs regulate gene expression. The abnormal expression of microRNAs has been reported in many human diseases. The purpose of this pilot study is to determine if microRNA expression is changed in untreated and interferon-beta-treated patients with multiple sclerosis.

The objective is to establish the impact of current disease modifying therapies (DMTs) and associated support services on Patient Reported Experience Measures and Patient Reported Outcomes in relation to the treatment and management of Relapsing Multiple Sclerosis in the United Kingdom (UK).

To explore whether treatment with glatiramer acetate (GA) may decrease iron deposition in subcortical deep GM, as detected by SWI-filtered phase imaging, in patients with RRMS over 24 months and compared to a reference population of healthy controls.

The purpose of this study is to collect biofluid samples for the banking and usage in ALS research. Through comparison of these samples, the researchers hope to learn more about the underlying cause of ALS, as well as find unique biological markers, which could be used to develop new therapies.

Study assessing cognitive function and physical activity in people with relapsing remitting multiple sclerosis.

The primary objective of the study is to determine which baseline and yearly response factors (clinical and para clinical) predict overall disease-free status at Month 12 and Month 24, and clinical disease-free status in subsequent Months 36 and 48. The secondary objectives are: To identify prognostic factors at Baseline that predict overall disease-free status at Month 12, and to assess if yearly overall disease-free response factors predict overall disease-free status at Month 24; To evaluate clinical disease-free status (relapse, Expanded Disability Status Scale [EDSS]) at each analysis time point of Months 12, 24, 36, and 48; To identify prognostic factors at Baseline that predict clinical disease-free status at Month 12, and to assess yearly clinical disease-free response factors that predict clinical disease-free status (relapse, EDSS) in subsequent years at Months 24, 36, and 48; To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: annualized relapse rate (ARR), sustained EDSS progression and improvement (24-week sustained); To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: magnetic resonance image (MRI) measures: T2, T1, T1 with Gadolinium (Gd), brain atrophy; To evaluate the impact of Tysabri at Month 24 and Month 48 on the following: optical coherence tomography (OCT), Low and High Contrast Visual Acuity Assessment; To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: cognitive impairment (Symbol Digit Modalities Test [SDMT]), capacity for work (Work Productivity and Activity Impairment Questionnaire [WPAI]), quality of life (QoL) (Multiple Sclerosis Impact Scale [MSIS-29])

The purpose is to collect data for ALS research. The data will be used to learn more about the origin of ALS and to improve quality of care for people with ALS. The information you provide in the ALS registry will be used to evaluate variations in patient care, adherence to standards of care and also to help foster ALS research.
