Filter by:In previous clinical studies, PS128 has been reported to ameliorate motor deficits in Parkinson's disease (PD). PS23 has been reported to delay some age-related disorders. On the basis of previous animal and clinical studies which hope that this study can support the theory of the gut-brain axis, and have the opportunity to realize the relationship between peripheral inflammation and neurodegeneration.
Development of a new mass spectrometry-based biomarker for the ear-ly and sensitive diagnosis of the Creatine Deficiency Syndromes from dry-blood-spot sample
Background: - Some people with movement disorders are in another NIH protocol. They will have electrodes placed in deep brain areas. They may do tasks before, during, and after surgery. Researchers want to learn more about how brain cells and networks work while people learn and remember. They want to use the data from the other NIH study to do this. Objective: - To share data from before and during deep brain stimulation surgery. The data will be used in a study of how the brain learns and remembers. Eligibility: - People at least 18 years old who are in protocol 11-N-0211 and have certain movement disorders. Design: - As part of protocol 11-N-0211, data on participants brainwave activity is collected. In this protocol, they will have that data stored and shared. - Researchers will access imaging data from deep brain stimulation surgery. - Researchers will access other medical records.
Movement disorders such as dystonia, hypertonia, and spasticity interfere with or prevent voluntary movement. Studies have suggested that using biofeedback to increase awareness of muscle activation can improve motor function in patients with motor deficits. The investigators hypothesize that the daily use of a surface electromyographic (SEMG) biofeedback device for one month will improve motor function in children and young adults with dystonia, hypertonia, and/or spasticity. The SEMG biofeedback device is worn over the muscle(s) the subject has difficulty in controlling and provides vibratory feedback about muscle activation. Groups of children and young adults (ages 3-21), with dystonia, hypertonia, and/or spasticity will be asked to wear a small (approx 1 square inch) sensory feedback device on their affected muscle(s) for 5 hours a day for one month. The device will vibrate and emit a blue light when the muscle is activated. At the start of the experiment, subjects will be tested on the Goal Attainment Scale (GAS), the Pediatric/Adolescent Outcomes Data Collections Instruments (PODCI), and the Barry Albright Dystonia Scale (BAD). For one month, subjects will practice goals without device. After a month, subject will be assessed again and be given device to practice goals for a month. After one month, the subjects will be tested on the outcome measures again and return device.
Objective The objective of this pilot study is to characterize the abnormal neuronal firing patterns of basal ganglia neurons and those in the premotor cortex in patients with treatment-resistant movement disorders undergoing deep brain stimulation (DBS) surgery. Study population Fifteen adult patients with treatment-resistant movement disorders who are undergoing deep brain stimulation surgery at Suburban Hospital, Bethesda, Maryland, will be studied. Design This is a physiology study of treatment-resistant movement disorder patients who have been scheduled for implantation of a deep brain stimulation device into the Nucleus accumbens. Prior to surgery, patients will learn a rewarded visual-motor task and undergo magnetoencephalography. The task will be repeated during DBS surgery, with collection of information on electrical activity including single neuronal unit and local field potentials. The task and MEG will be repeated 3-4 months after surgery. The collected data will be analyzed for coherence patterns during rest and rewarded movements. Outcome measures We plan to characterize and quantify the oscillatory activity present in motor circuits of treatment-resistant movement disorder patients during rewarded visually guided movements. We hypothesize that during visually guided movements, neuronal coherence will be significantly increased relative to resting periods. Thus, by better understanding the alteration in oscillatory patterns in these patients, we hope to develop better DBS stimulation paradigms in order to better treat this disease in the future.
