12 Clinical Trials for Various Conditions
The purpose of this protocol is to (1) Determine whether a one-on-one mindfulness meditation intervention or audio training improves performance on an adaptive communication system that utilizes brain-computer interface (BCI); and (2) Determine whether the intervention reduces stress in subjects with severe speech and physical impairments (SSPI). Hypothesis: The group of subjects randomized to the mindfulness meditation training will improve BCI performance and stress levels more than the audio control group.
The primary aim is to show balance training improves DCD individual's ability to compensate for their activity limitations, but does not impact disease progression. The second aim is to demonstrate aerobic exercise improves balance and gait in DCD persons by affecting brain processes and slowing cerebellar atrophy.
Friedreich's ataxia is characterized by progressive alterations in the function of the cerebellum accompanied by an atrophy of the spinal cord. Although the genetic defect responsible for the disease has been identified more than 15 years ago, objective markers of the pathologic process (i.e., biomarkers) that would allow measuring the effects of potential therapies are still lacking. Moreover, it is still unclear how the malfunction of the cerebellum affects the rest of the brain, and understanding the connectivity and neurochemistry of the central nervous system might yield new insights in the understanding of the disease, in addition to providing potential markers. To address these needs, the investigators aim at utilizing the capabilities of Magnetic Resonance Imaging (MRI) and Spectroscopy (MRS). Using techniques called Diffusion Imaging, resting-state functional MRI, and Proton Spectroscopy (1H MRS), the investigators propose to determine the differences in the connectivity and neurochemistry of the spinal cord and the brain between patients affected by Friedreich's ataxia and healthy controls. The investigators plan on imaging both patients and control subjects using a 3T magnet, a system that although not yet available in all medical facilities, is becoming standard in most hospitals and clinics. The first aim is to scan patients already scanned last year (12-month follow-up). The second aim is to scan patients at an early stage of the disease.
This is a natural history study prospectively investigating neuroimaging markers of disease progression in children and adults with Friedreich ataxia (FA). There will be three assessment periods (baseline, 12 and 24 months). The study will include approximately 200 individuals with FA and 100 matched controls recruited across the six international academic sites. Other assessments will include secondary clinical and cognitive markers, as well as exploratory blood markers.
Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) affecting roughly 900,000 people in the United States that frequently results in impaired mobility. The majority of people with MS express that impaired mobility the most difficult aspect of living with the disease. Ataxia is one aspect of impaired mobility experienced by approximately 80% of persons with MS. Despite $9 billion in drug costs to patients with MS in the U.S., in 2012 alone, standard pharmacological treatment for MS is ineffective in restoring mobility and decreasing ataxia. The PI designed a targeted ballet program requiring motor learning of complex movements that mitigated ataxia and improved balance in patients with MS in a pilot study. The improvements obtained were approximately five times larger than those reported by other physical rehabilitation interventions. However, understanding these changes requires determining whether there are underlying changes in the brain after participation in the targeted ballet program. This project involves persons with mild-to-moderate MS that present ataxia in their movement. We will compare the brain connectivity of participants in the targeted ballet program before and after the 16-week, twice per week, hourly participation intervention. Brain images will be obtained with magnetic resonance imaging while each participant rests with the eyes open. As a secondary outcome, measures of movement quality, ataxia, and balance will be taken to better understand the effects of the targeted ballet program on motor function, wellness, and the brains of persons with mild to moderate MS. Test on movement will include a 10 meter walk with motion tracking, a balance test using a force plate, and clinical tests of ataxia, balance, and walking speed. We will also assess changes in wellness with standard questionnaires.
The proposed study aims to characterize ataxia occurring in essential tremor and essential tremor with DBS.
This study will test an investigational drug called AZD1390 in combination with radiation therapy for the treatment of brain tumors. This is the first time AZD1390 is being given to patients. This study will test safety, tolerability and PK (how the drug is absorbed, distributed and eliminated) of ascending doses of AZD1390 in combination with distinct regimens of radiation therapy
Positron Emission Tomography (PET) is a technique used to investigate activity in areas of the brain. The PET technique allows researchers to study the normal processes in the brain (central nervous system) of normal individuals and patients with neurologic illnesses without physical / structural damage to the brain. When a region of the brain is active, it uses more fuel in the form of oxygen and sugar (glucose). As the brain uses more fuel it produces more waste products, carbon dioxide and water. Blood carries fuel to the brain and waste products away from the brain. As brain activity increases, blood flow to and from the area of activity also increases. This is known as regional cerebral blood flow (rCBF). Knowing these facts, researchers can use radioactive water (H215O) and PET scans to observe what areas of the brain are receiving more blood flow. In this study researchers plan to investigate the changes in regional cerebral blood flow (rCBF) as patients participate in different activities. The activities are designed to stimulate the areas of the brain responsible for voluntary motor activity and sensation. By comparing the results of PET scans performed in different conditions, researchers can locate regions of the brain responsible for specific tasks. This study should provide new information about voluntary movements in humans and the preparation involved in controlling them.
The primary goal of this study is to address the need for targeted therapeutic interventions for impairments that impact walking in related neurodegenerative diseases.
To assess the impact of a 12-week virtual seated physical intervention on cardiovascular health and wellness in people with chronic neurological impairments (CNI).
Patient Power is a patient research network and database (registry) to collect prospective information about demographics, self-reported diagnoses and medications, and willingness to participate in research from participants with rheumatoid arthritis (RA), spondyloarthritis (SpA), other musculoskeletal conditions, chronic neurological conditions like migraine, chronic pulmonary conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, autoimmune dermatological conditions such as psoriasis, and other chronic inflammatory or immune-mediated conditions. In addition, since patients with chronic conditions often have other co-morbidities like cardiovascular health and obesity-related metabolic disorders, these conditions will also be included. Participants will provide information from their smartphones or personal computers. The information will be used by researchers and clinicians to help patients and their providers make better, more informed decisions about treatment of chronic conditions.
To evaluate the safety and efficacy of transplantation of human induced pluripotent stem cell-derived dopaminergic progenitors, CT1-DAP001, into the corpus striatum in patients with Parkinson's disease
