Multi-Site Registry study

The purpose of the study is to test new biomarkers of amyotrophic lateral sclerosis (ALS) and primary lateral sclerosis (PLS) using MRI scans at 3 tesla (3T). Identifying biomarkers of a disease can lead to a better understanding of the disease as well as improved treatments.

This research is being completed to examine the cells, brain imaging, and speech in individuals with REM Sleep Behavior Disorder who are taking serotonergic medications such as Citalopram, Escitalopram, Fluoxetine, Fluvoxamine, Paroxetine and Sertraline. The purpose of examining these is to try and see if we can predict signs of Dementia with Lewy bodies (a progressive form of dementia with an increase in decline of thinking, reasoning, and other functions). This may benefit others by enabling us to diagnose Dementia with Lewy Bodies sooner rather than later.

This study will be measuring brain activity using EEG and assessing motor skills and speech in children following cancerous brain tumor resection. No direct cancer treatments or objectives are being targeted.

The overall objective of this study is to determine the feasibility of identifying transdiagnostic biomarkers of cognitive function mediated by neuromodulation of the dorsolateral prefrontal cortex that are translatable across disease groups in order to more accurately phenotype clusters of cognitive dysfunction. Completing behavioral paradigms with electrophysiology and TMS is a challenging frontier. This study focuses on the feasibility of such an endeavor for those with chronic pain or depression as well as healthy controls.

We are studying the effects of stimulating the vagus nerve. The vagus nerve connects the brain to many organs in the body. Vagus nerve stimulation (VNS) is already approved by the United States Food and Drug Administration (FDA) to treat depression and epilepsy. We want to learn more about how it affects other parts of our bodies, such as the heart, metabolism, the immune system, and the nervous system. We hope that by understanding how VNS affects the body as a whole, we can develop new treatments for other conditions, or help to improve its use for depression and epilepsy.

This study identifies the bio-behavioral predictors and correlation of responses to Comprehensive Behavioral Intervention to Tics (CBIT) in young people with tic disorder.

We are exploring ways to promote healthy lifestyles during stroke rehabilitation using a web-based rehabilitation program. The purpose of this study is to compare two intervention approaches: teleABLE and Healthy Lifestyles Education. Both interventions are delivered using video visits, so participants can complete all study activities from home

The purpose of this research study is to test the efficacy of the study drug, Brivaracetam, to reduce nerve pain in SCI. We also want to determine whether Brivaracetam impacts mood, brain, and genes to help us design more research with this study drug in the future. We will assign you randomly to one of 2 groups: the group that receives the active study drug (Brivaracetam) or the group that receives a placebo (sugar pill). There is a 50-50 chance that you will be assigned to one group or the other, similar to flipping a coin. Participation in this study will last approximately 11 weeks and will include 3 study visits to the study site; however, participation in the study can also be entirely virtual which would require no visits to the study site.

Through this research, the study staff hopes to better understand how DBS works and to define the optimal site in the brain for DBS treatment for Parkinson’s Disease. You will be asked to come for one study visit where you will perform some physical and mental tasks while on and temporarily off your medications and DBS treatment. Participation in this research study will take 7-8 hours.

This protocol will characterize the effects of deep brain stimulation (DBS) location (both adverse and beneficial) on motor signs in people with Parkinson’s disease (PD). This information can be used to inform future DBS protocols to tailor stimulation to the specific needs of a patient. If targeted dorsal GP stimulation is shown to significantly improve motor features that are typically resistant to dopamine replacement therapy, these experiments will likely have major impact on clinical practice by providing a potential strategy to treat medically intractable symptoms.

Study objectives: -To characterize spontaneous and movement-related LFP changes in STN and GP in externalized patients under conditions that modulates the severity of tremor, bradykinesia and rigidity (off meds/off stim; on meds/off stim; off meds/on stim, on meds/on stim). -To characterize and compare the relative effect of different forms of closed loop stimulation (e.g., triggered at specific thresholds of low beta/HFO PAC or beta band activity) to standard isochronal high frequency DBS on motor signs and performance during movement.

We are looking at adding lomustine to temozolomide and radiation therapy when compared to temozolomide and radiation therapy alone (usual care). We will compare the effect (shrinking or stabilizing) and side effects when treating newly diagnosed MGMT methylated glioblastoma. Each of the drugs and radiation work in a different way to stop the growth of tumor cells.

1.1 Purpose: This protocol will carry out Aim 2 (Experiments 1 and 3) of Udall Project 2, leveraging the novel (on-label, FDA-approved) local field potential measuring capability of the Medtronic Percept™ PC DBS system to study the effects of globus pallidus internus and globus pallidus externus (GPi, GPe) DBS on: the wash-out and wash-in dynamics of motor behavior and local field potentials (LFPs) and correlations between fluctuations in gait and LFPs during activities of daily living (recorded over 4 weeks).

The goal of this study is to provide comprehensive longitudinal assessments of a cohort of PD patients before, during, and after DBS surgery, including neurological, neurophysiological, and neuropsychological data.

We are researching the benefits of physical therapy guided exoskeleton gait training in people with a spinal cord injury. We want to describe the benefits to overall function and how the brain changes after gait training.

This study aims to investigate whether there is difference in ankle position sense acuity between people with Parkinson's with freezing of gait and without freezing of gait. It also examines the relationship between position sense acuity and severity of freezing of gait, and gait measurements.

The purpose of this study is to compare the effects of 2 different levels of exercise intensity and to learn more about effects of aerobic exercise for people with Parkinson’s disease (PD). This study will help us better understand what exercise guidelines should be used in the future.

This study will compare the effects of apixaban to aspirin in patients who have atrial fibrillation and a recent brain hemorrhage to see which is better in preventing strokes and death.

This study is about a genetic condition called Adrenoleukodystrophy (ALD). The first goal of this study is to understand more about how ALD affects a child’s brain and development in childhood as they take part in medical care and monitoring. This is important to identify the optimal ways to detect and treat manifestations of ALD such as cerebral ALD. The second goal is to learn about how ALD affects caregivers, so that clinicians can offer better support to families in the future. We will also have healthy comparisons to help to learn more about the condition (ALD) being studied, by comparing the information collected to a child without the condition.

This project is a data and specimen repository for developmental disorders. Participants provide biological samples and permission to store their health-related data. The purpose is collect and manage these materials for use in biomedical research related to developmental disorders.

We are exploring ways to help people with stroke and their caregivers be more physically active in their daily lives. The purpose of this study is to determine whether delivering the web-based Activating Behavior for Lasting Engagement (ABLE) program to duos is a feasible and acceptable approach.

Study to examine the physiological responses that occur during a hot flush in postmenopausal women

The objective of this study is to describe how activation of distinct pathways in and around the subthalamic nucleus (STN) and internal segment of the globus pallidus (GPi) correlate to changes in sleep outcomes in movement disorders patients after deep brain stimulation (DBS) surgery targeting these structures.

REM sleep behavior disorder may predict the eventual symptom development of Parkinson’s disease, dementia with Lewy bodies, or multiple system atrophy. This occurs over years to decades and the sleep disorder may hide other typical symptoms and result in a delay in diagnosis. We are studying the changes in the brain over two years. We will do high field MRI’s (7T) and other tests of neurological function of people who have REM sleep disorder and people who don’t have this disorder (matched for age and sex).

The goal of this proposal is to develop fully automated, high performance, motion-corrected MRS sequences for the brain and spinal cord, that are also easy to share (no additional external hardware needed) with other institutions and easy to use.

The purpose of this study is to look at symptoms, thoughts, and behaviors related to the way a person sees the world. This is called visual perception. This study will also look at brain function. We will study these things in people with and without psychosis. People with psychosis see the world differently than others. For example, they may experience hallucinations. We are interested in understanding how differences in the way people see the world relate to brain circuits. This project will use visual and behavioral experiments, EEG, and Magnetic Resonance Imaging (MRI) to look at how visual perception is different in people with and without psychosis. This research study has three visits lasting 2-4 hours each. We expect that these visits will take place over 2-3 months, depending on your availability and preferences.

We are exploring ways to increase physical activity after stroke using a web-based rehabilitation program. The purpose of this study is to adapt the Activating Behavior for Lasting Engagement (ABLE) program using video visits so people with stroke can participate from home.
