Clinical trials Below are current clinical trials.104 studies in Neurology (open studies only). Filter this list of studies by location, status and more. Blood and Spinal Fluid Collection for Research Studies in Motor Neuron Disease and Motor Neuropathy Rochester, Minn. The purpose of this study is so that blood (plasma and blood cells) and/or extra spinal fluid (which was taken for clinical purposes) can be obtained and stored for later research on a large cohort of patients with progressive motor neuronopathies and neuropathies, many of which will be determined to suffer from Amyotrophic Lateral Sclerosis (ALS). Cerebrospinal Fluid Biomarkers For Brain Tumors Rochester, Minn. The purpose of this study is to help generate a repository of Cerebrospinal Fluid (CSF) samples relevant to neuro-oncology research that may facilitate the identification of biomarkers that are predictive of disease burden, therapeutic susceptibility or response to therapy. This protocol will also provide a vehicle for CSF access for patients or providers wishing to generate or evaluate individualized biomarkers as part of other research or individualized therapy protocols. Dominantly Inherited Alzheimer Network (DIAN) Jacksonville, Fla. The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation. Magnetic Resonance Elastography of Traumatic Brain Injury Rochester, Minn. This purpose of this pilot study is to determine if there are changes in mild TBI detectible with MRE. This is the first time this novel technology has been applied to mild TBI and the anticipated results are theoretical. Acute Modulation of Stereotyped High-Frequency Oscillations Rochester, Minn. The purpose of this study is to do data collection of EEG findings to determine whether new types analysis of intracranial EEG can add different and possibly useful information to standard types of analysis of intracranial EEG. Intracranial EEG data will be collected intraoperatively and postoperatively during routine clinical monitoring, and will be analyzed by researchers for functional brain mapping and the investigation of high frequency oscillations (HFO's), for the purpose of identifying functional and epileptogenic brain areas. A Registry of Biospecimens for Patients with Central Nervous Systems Inflammatory Disease Rochester, Minn. The purpose of the study is to learn more about inflammatory diseases of the central nervous system (CNS) by collecting patient information, blood sample (which contain a person’s genes, DNA) and other available tissue samples. A Study to Evaluate Biomarker Target Stimulation Rochester, Minn. The purpose of this study is to understand how electrical stimulation of the brain can modulate and suppress interictal epileptiform activity as a step on the path to developing new therapies for epilepsy. Resting State Connectivity in Adolescents with Postural Orthostatic Tachycardia Syndrome and Chronic Pain Rochester, Minn. The purposes of this study are to compare the functional connectivity in adolescent patients with Postural Orthostatic Tachycardia Syndrome (POTS) both with and without chronic pain, to those with chronic pain alone, to that of healthy controls; to evaluate whether there is a change in functional connectivity following participation in an intensive rehabilitation-oriented program previously demonstrated to have excellent outcomes with regard to functional recovery and symptom control; and to correlate outcomes using standardized symptom and function rating scales to imaging findings. A Study Of Vagus Nerve Stimulation (VNS) With Mobility Training For Gait Recovery After Chronic Ischemic Stroke Rochester, Minn. The purpose of this study is to evaluate the safety, feasibility, and efficacy of vagus nerve stimulation (VNS) paired with mobility training to improve lower extremity function and gait in individuals with chronic ischemic stroke. Sex-Specific Effects Of Endocrine Disruption On Aging And Alzheimer's Disease Jacksonville, Fla., Rochester, Minn. The researchers are trying to determine whether ovarian hormones are associated with aging processes and with the risk of developing Alzheimer's disease in women.

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.
