This study will examine the brain activation associated with the transition between movements in Parkinson’s disease, and if these changes are related to the development of problems with moving (like freezing of gait) and thinking. We will look at brain activity associated with the vestibular (inner ear) and cortical (surface of the brain) systems. People with Parkinson’s disease (especially people with freezing of gait) sometimes have difficulty initiating changes in movement types, such as going from standing to walking, turning, or switching between slow and fast repetitive movements. The difficulty in movement transitions may be associated with an overactive vestibular system (inner ear) or cortical system. In each experiment in this study, we expect about 20-25 participants with Parkinson’s disease and freezing of gait, 20-25 participants with Parkinson’s without freezing of gait, and 20-25 control participants

The purpose of this study is to determine how different bladder management methods affect the quality of life for young people with spina bifida. We hope to find out if certain bladder management methods are associated with a better quality of life. This information could help doctors make better treatment decisions and counsel young people living with spina bifida.

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 research will use neuroimaging to study the brain systems involved in prioritizing goals effectively, as well as testing whether variation in those systems is associated with the personality trait conscientiousness, which reflects organization, self-discipline, and industriousness and predicts important health and other life outcomes.

This study is for people who have essential tremor and will be receiving the Boston Scientific Vercise Genus deep brain stimulation (DBS) system. We are studying the possibility that a kind of deep brain stimulation called "coordinated reset" stimulation (CR-DBS) will be more effective than current DBS treatment for essential tremor. We expect that participants will be in this research study for about 9 to 11 months.

Participants play games designed to train visual attention towards natural, non-drug-related scenarios. A biofeedback loop between gameplay and an electroencephalogram (EEG) system monitors game performance and guides game difficulty.

The Brain Health Registry and Biospecimen Repository will create a research framework aiming to help us understand the causes of memory loss in Alzheimer's disease and other neurodegenerative disorders. We would like to recruit research participants 45+ years and up without any memory complaints, participants subjectively reporting memory complaints, and participants suffering from mild cognitive impairment or dementia symptoms due to neurodegenerative diseases. We will ask study participants about their medical history, their demographics, their social determinants of health, do a sleep quality assessment, and do neuropsychometric assessments. We will also create a biospecimen repository of blood, tissue and cerebral spinal fluid samples from the above participants.

The purpose of the study is to establish and maintain a biorepository of tissue and biospecimen samples relevant to Amyotrophic Lateral Sclerosis (ALS) research. We will obtain, store, and catalogue peripheral blood mononuclear cells (PBMCs), blood and blood components, skin punch biopsy samples, and cerebral spinal fluid (CSF) from people living with ALS, linked to clinical datasets, to advance ALS research.

This is a small, Phase 0, window of opportunity study to provide human experience to support our pre-clinical data and gain preliminary information regarding the safety and tolerability of mirdametinib and vorinostat when given in combination.

The purpose of this research study is to compare surgical tumor removal followed by stereotactic radiotherapy (SRT) to surgical tumor removal followed by radiation therapy delivered by surgically implanted GammaTilesTM (GT). A GammaTile (GT) is an FDA cleared device used to provide radiation therapy following the removal of a brain tumor. GT are small (2cm x 2cm x 0.4cm) collagen squares/tiles that contain sources of radiation that look like grains of rice. If assigned to the GT study group, the doctor will place tiles containing the radiation sources in the cavity left after surgically removing the brain tumor. They do not need to be removed as the collagen tiles will be absorbed and the radiation sources can be left in place. If assigned to the SRT study group, SRT will take place 3-4 weeks after surgery and uses external beams to deliver radiation to the cavity left after surgically removing the brain tumor.

We are conducting this research to try to find a better way of treating Parkinson's disease, specifically postural instability and gait disturbances (PIGD) by looking at certain brain characteristics using 3T magnetic resonance imaging (MRI.) We think we could discover how to make DBS more effective for such things as postural gait instability and other symptoms of PD. Participants will be asked to come to our research location, walk on a treadmill, and have a 3T MRI.

The purpose of this research is to better understand how deep brain stimulation settings can affect the electrical activity in the brain and the frequency of seizures. There are a number of different ways in which the deep brain stimulation electrodes can be programmed to stimulate the brain. This research study uses the implanted battery in the chest to record electrical activity from the brain at different stimulation settings. We then use this electrical activity to determine stimulation settings that are “personalized” to your brain.

The purpose of the study is to test new biomarkers of ALS using MRI scans at 3 Tesla (3T). A biomarker is a measurable characteristic that can be used as an indicator of a particular disease state. Identifying biomarkers in ALS will help test new treatments and may help us make diagnoses earlier.

We are doing this study to see if we can improve the standard treatment for OCD, Exposure with Response Prevention, by pairing it with Transcranial Magnetic Stimulation to the parts of the brain that cause OCD symptoms.

The purpose of this study is to test the effects of an in person or home-based exergame intervention on improving cognition and fitness in community-dwelling older adults with memory complaints. The exergame refers to a new low-cost virtual reality cognitive game with cycling. We expect that participants will be in this research study for 4 months. Intervention sessions will require approximately 1 hour, 3 days per week for 3 months.

Humanitarian use devices are medical devices approved by the FDA for the treatment of medical conditions affecting fewer than 4,000 patients per year. The FDA reviewed the safety of the device and determined that the probable health benefits outweigh the risks of injury or illness from its use. Effective treatment of symptoms, however, has not been studied in formal clinical trials. Medtronic DBS Therapy delivers electrical stimulation to areas in the brain to help control symptoms of various movement disorders. You may be a candidate for Medtronic DBS Therapy for Dystonia if you have been diagnosed with chronic, intractable (drug refractory) primary dystonia. You or your third party payer (health insurance, Medicare, Medicaid or other) must provide payment for hospital, office and other medical costs related to this therapy.

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.
