Clinical trials Below are current clinical trials.99 studies in Neurology (open studies only). Filter this list of studies by location, status and more. HEALEY ALS Platform Trial Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz. The purpose of this study is to evaluate the safety and effectiveness of investigational products for the treatment of ALS. The Neurobiology of Two Distinct Types of Progressive Apraxia of Speech Rochester, Minn. The purpose of this study is to identify and distinguish two different types of Progressive Apraxia of Speech through clinical imaging and testing. Posterior Fossa Decompression with or without Duraplasty for Chiari Type I Malformation with Syringomyelia Rochester, Minn. The purpose of this study is to determine whether a posterior fossa decompression or a posterior fossa decompression with duraplasty results in better patient outcomes with fewer complications and improved quality of life in those who have Chiari malformation type I and syringomyelia. A Study to Evaluate fMRI of Active Deep Brain Stimulation in Epilepsy Jacksonville, Fla. The purpose of this study is to to use functional imaging to study the mechanisms of anterior thalamic nucleus (ANT) Deep Brain Stimulation (DBS). A Study to Evaluate Caregiver Connections via Technology for Patients with Alzheimer's and Other Types of Dementia Rochester, Minn. The purpose of this study is to optimize profile questionnaire and matching algorithm developed in Phase I and implement in final website design, and to determine if algorithmically matched participants have statistically significant increase in match satisfaction and self-reported sense of resiliency and quality of life over randomly matched caregivers. Breast Cancer, Reasoning, And Activity Intervention Scottsdale/Phoenix, Ariz. This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer. A Study of Molecular Anatomic Imaging Analysis of Tau, the Primary Pathological Protein in Progressive Supranuclear Palsy Rochester, Minn. The purpose of this study is to learn more about the distribution of the pathological protein tau in the living brains of patients with Progressive Supranuclear Palsy (PSP). A Study of Nervous System Involvement of Coccidioidomycosis at Mayo Clinic Hospital in Arizona Scottsdale/Phoenix, Ariz. The purpose of this study is to gain a better understanding of the presentation, diagnostics, disease course and treatment variations, as well as the factors that may influence features of neuro-invasive Coccidioidomycosis. A Study of Pyridostigmine in Postural Tachycardia Syndrome Rochester, Minn. This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure. A Study to Evaluate Sex Differences in Multiple Sclerosis Spectrum of Demyelinating Disorders Rochester, Minn. The purposes of this study are to explore the association between female sex, reproductive history and clinical phenotypic variability in multiple sclerosis (MS), to explore the association between female sex, reproductive history and radiologic phenotypic variability in MS, and to explore the association between female sex, genetic and environmental interactions in MS.

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.
