Clinical trials Below are current clinical trials.94 studies in Neurology (open studies only). Filter this list of studies by location, status and more. A Study to Evaluate Sleep for Stroke Management and Recovery Rochester, Minn. The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke. Pre-operative Vs. Post-operative Radiosurgery For Metastatic Brain Tumors Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to determine whether there is an increase in the time of a first occurrence of either: local recurrence, leptomeningeal disease, or symptomatic radiation brain necrosis in patients with brain metastases who receive SRS prior to surgery as compared to patients who receive surgery prior to SRS. A Phase 3 Efficacy and Safety Study of Pitolisant in Patients with Prader-Willi Syndrome Rochester, Minn. The purpose of this study is to evaluate the impact of pitolisant on Excessive daytime sleepiness in patients with Prader-Willi syndrome. A Study to Evaluate Rozanolixizumab to Treat Patients with Generalized Myasthenia Gravis Rochester, Minn. The purpose of this study is to assess the safety, tolerability, and effectiveness of additional 6-week treatment cycles with Rozanolixizumab in study participants with generalized myasthenia gravis. A Study of Multicenter Outcomes in Pediatric Status Epilepticus Rochester, Minn. The purpose of this study is to develop a prospective status epilepticus registry among twelve tertiary care pediatric hospitals in the United States focused on standardizing status epilepticus outcome assessments. Detection of Vascular and Inflammatory Plasma Biomarkers in Patients Diagnosed with Obstructive Sleep Apnea and MRI-defined Cerebral Small Vessel Disease Jacksonville, Fla. The purpose of this study is to evaluate plasma biomarkers of vascular function and inflammation in patients with newly-diagnosed Obstructive Sleep Apnea (OSA) and pre-existing imaging evidence of Cerebral Small Vessel Disease (CSVD). ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) Rochester, Minn., Jacksonville, Fla. The purpose of this study is to evaluate sporadic (s-) and familial (f-) frontotemporal lobar degeneration (FTLD) patients and asymptomatic family members of f-FTLD patients, characterizing the cohorts longitudinally and informing clinical trial design. FTLD is a neurodegenerative disorder of the nervous system which there are no approved treatments or cures. The study has two arms: a “longitudinal arm” involving a comprehensive assessment of clinical, functional, imaging, and biofluid data collection, and a “biofluid-focused arm” involving limited clinical data to accompany biospecimen collection. Image-based Mapping of Brain Tumors Scottsdale/Phoenix, Ariz., Rochester, Minn. The purpose of this study is to combine MRI images with histologic and genetic analysis of cancer (from blood and tissue samples) to improve the overall accuracy of diagnosis and effectiveness of cancer treatment. A Study of Early-onset Alzheimer's Disease Rochester, Minn., Jacksonville, Fla. The purpose of this Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is designed to look at disease progression in individuals with early onset cognitive impairment . Clinical/cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EO-nonAD) participants,and (3) cognitively normal (CN) control participants. A Registry Called Every Child for Collecting Data and Biology Specimens on Younger Patients with Cancer Rochester, Minn. The purpose of this registry called Every Child, is to collect data and biospecimens from multiple body sources for younger patients with cancer over time. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
