Active clinical trials for "Stroke"

To investigation the association of thrombosis and inflammation genes with sub-clinical cardiovascular disease and with incident myocardial infarction and stroke in older adults.

No universally successful therapy exists that promotes recovery of motor function after a stroke, the main cause of long-term disability among adults. The purpose of this study is to develop strategies to improve recovery of lost motor function. It will combine motor skills training with a brain-stimulating technique called transcranial direct current stimulation (tDCS). Healthy adult volunteers and adult stroke patients will be enrolled in this study. Participants will come to NIH for a clinical and neurological exam, and, if necessary, an MRI [magnetic resonance imaging] examination. Participants will return for 4 sessions; each lasting approximately 3 hours. The first will be a practice session during which participants will become familiar with the motor skills required of them in this study, such as performing finger movements on a keyboard, pinching, tapping, making wrist movements, and lifting small items. In sessions 2 and 3, participants will perform the motor skills they practiced in session 1 while receiving tDCS. During session 4, they will receive tDCS only, with no performance of motor skills. During tDCS, investigators will place electrodes with a gel on participants' heads and pass the tDCS current between these two electrodes. tDCS is a painless procedure. Participants will receive up to $420 in compensation for their involvement in this study. ...

To examine associations between various dietary elements and the risk of coronary heart disease and stroke.

To examine markers of underlying chronic inflammation and infection as potential risk factors for future myocardial infarction (MI), stroke (CVA), and venous thromboembolism (VTE) in plasma samples collected at baseline from healthy participants in the Physicians' Health Study (PHS).

Background: - People can learn to use feedback about brain activity to change that activity. Researchers want to see if people who have had a stroke can change their brain activity by practice and thought with feedback, and if that improves motor control. They will study brain activity in people who have and have not had strokes. Objectives: - To see if people with stroke can change their brain activity and improve motor control by practice and thought. Eligibility: Adults 18 80 years old who have had a stroke. Healthy volunteers 18 80 years old. Design: Participants will be screened with a medical history, MRI, and physical exam. For MRI, a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides in and out of a cylinder. They will be in the scanner less than 2 hours, lying still for up to 15 minutes at a time. The scanner makes loud noises. Participants will get earplugs. Participants will have up to 3 scanning visits and up to 3 follow-up visits within 24 weeks. Visits may include screening, MRI, functional MRI (fMRI), questionnaires, and simple motor tests. Stroke participants may take additional motor tests, including transcranial magnetic stimulation (TMS). fMRI: During this MRI, small metal disks may be taped to the skin or a fabric glove with small wires in it may be used to monitor hand movements. Heart rate and breathing may also be monitored. Participants may be monitored by video and asked to perform tasks. TMS: A brief electrical current goes through a coil on the scalp. It creates a magnetic pulse that stimulates the brain. Participants may be asked to perform simple actions. Finger or hand movements may be recorded.

Through 5 years continuous observation of acute ischemic stroke patients in Neurology Department of Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, clinical data about emergency treatment (neurological score, examination and treatment), medical data after admission (neurological score, inspection, examination and treatment) and long-term prognosis (neurological score) was collected. The outcomes were set as the score scale, all blood test index and examination index of the research objects at specific period after illness. Through statistical analysis and comparison of different in-hospital clinical data in predicting the outcome of the patients, our study will provide more evidence-based solutions for the treatment and prediction of acute ischemic stroke.

Impaired motor function is common after stroke. Individuals with stroke often exhibit synergic pattern that disturb daily function. It is crucial to identify the movement impairment in the clinical settings. Upright Motor Control Test (UMCT) is one of the tests developed to assess the selective movement control and functional strength in people with central nervous disorders. It can be used to reflect the impairment of motor function and evaluate changes of performance after treatment. Yet is little to know the clinimetrics of the UMCT on clinical utility. To date, only few researches explore that UMCT has some construct and criterion validity. Therefore, this study aims to 1) establish the inter-rater reliability to administer the UMCT. 2) explore the correlation between the Fugl-Meyer Assessment of Motor Recovery after Stroke (FMA) and UMCT. 3). investigate whether the UMCT is able to predict the walking ability in patients with stroke.

This study is a French multicenter prospective study including 5 stroke units with available MRI and F-MISO PET for patients with acute ischemic stroke. Background and Purpose: 18F-Fluoromisonidazole (FMISO) PET has been used to identify hypoxic tissues in animals and stroke patients. While MRI has become the gold standard acute stroke imaging, no published study has compared FMISO PET and MRI. The aim of this prospective study is to identify hypoxic tissues in 40 patients with acute ischemic stroke with F-MISO PET and to compare the location and the outcome of these hypoxic cells with MRI datas (weighted diffusion and FLAIR) and to clinical outcome.

Pilot study of continuing aspirin versus switching to clopidogrel after stroke or transient ischemic attack.

In hemiplegic, there is very little data on the impact of neurological deficit on the microarchitecture independent of bone mineral density and composition of the bone marrow. Rare studies have shown the relationship between some micro-architectural parameters and severity of neurological deficit. There is no study in humans on the evolution of the parameters of the microarchitecture assessed by 3D micro-tomography in the early phase of the installation of neurological deficits after stroke, in terms of a bearing bone, tibia, that a non-load bearing bones, radius.
