Filter by:This study evaluates the safety, feasibility and usability of a SaeboGlove rehabilitation device in the treatment of patients who have reduced ability to open their hand due to weakness after an acute stroke.
In this study, the researchers will investigate whether the E-effect is present in stroke subjects both on the subjective visual and postural vertical test. In addition, researchers will investigate the impact of the loss of different sensory information sources on the sensory reweighting strategies and perception of verticality by measuring the effect of somatosensory loss on the E-effect.
To compare the effects of various combinations between 6 hertz(Hz) rTMS & LFrTMS on the limb motor dysfunction due to cerebral vascular disease.
This is a multicenter, prospective registry clinical study to evaluate the real-world efficacy and safety of intra-arterial treatment for acute ischemic stroke using Revive SE device on the basis of standardised medical treatment.
This study encompasses the maintenance and utilization of a repository of samples from patients with cerebrovascular disease and stroke. The types of tissue taken are blood, cerebrospinal fluid (CSF), tissue, and microdialysis samples. Future analysis of these samples can potentially help investigators to better categorize groups of patients, understand the underlying etiology of these pathologies, identify markers that are associated with favorable or poor outcomes, and track changes that occur during the natural course of the disease or with treatment. This is a prospective observational study which will use samples from such patients to create this library which can be used to explore these questions in the future.
The registry is the main objective exhaustive list of cases validated stroke brain on a geographical area defined to calculate an incidence.
Cervicocerebral artery dissection is a major cause for stroke in young adults. While knowledge of cervical artery dissection (CeAD) has increased thanks to a number of high quality studies, knowledge on intracranial artery dissection (IAD) is limited. Due to treatment and publication bias little is known about the natural history of IAD. Overall, IAD is assumed to have a more severe course than CeAD, with a more ominous outcome in patients with subarachnoid hemorrhage (SAH). Furthermore, little information is available on the risk of recurrent IAD as well as on the risk of recurrent ischemic and haemorrhagic events in non-Asian patients. Radiological diagnosis of IAD can be challenging given the small size of intracranial arteries, and the subtle and non-specific radiological signs which tend to evolve over time. The optimal treatment of IAD is unknown. There are no randomised trials and only observational studies with relatively small sample sizes are available, thus providing a very low level of evidence. Finding the factors that are decisive for outcome and recurrence after intracranial artery dissection is key to an improved management of this potentially severe disease predominantly affecting young patients. By using standardised protocols for diagnosis, imaging and follow-up, the investigators intend to obtain large representative patient samples in order to fill the gap of evidence.
Introduction: Cerebral small vessel disease (SVD) is associated with age-related disabilities including dementia, depression, physical and functional impairment. Chinese are more prone to developing SVD than Caucasians. Physical exercise may improve multiple negative consequences associated with SVD. Objective and hypothesis to be tested: To examine the effects of a 24-week structured aerobic dance training on cognition, mood, physical and daily functions in stroke and dementia free older adults with SVD, and whether such effects are mediated through improved cerebral vasomotor reactivity (CVR), a marker of cerebral autoregulation which is impaired in SVD. Design and subjects: Rater-blind RCT comparing the effects of 24-week of structured aerobic dance training upon cognition, mood, physical and daily functions on 110 community dwelling, stroke- and dementia-free persons aged ≥65 with MRI evidence of significant SVD, defined as the presence of multiple (≥2) lacunes and/or early confluent or confluent WML. Interventions: Participants are randomized in a 1:1 ratio into a 24-week of structured therapist-led group aerobic dance training with home practice or simple stretching plus health education control group. Main outcome measures: Cognition, mood, physical and daily functions and CVR measured using Transcranial Doppler at baseline, weeks 12, 24 and 36. Data analysis: Intent-to-treat with multiple imputations with treatment efficacy analyzed using mixed effects models. Mediation effects of CVR between aerobic dance training and treatment outcomes tested using mediation models. Expected results: In persons with significant SVD, aerobic dance training improves cognitive, mood, physical and daily functions and such effects are mediated by changes in CVR.
To explore the prevalence of genetic polymorphism on RNF213 rs112735431 gene in non-cardioembolic ischemic cerebrovascular disease in Thai patients.
This study focuses on implementing Yellow 560 for the direct intraoperative visualization of Fluorescein Sodium stained intracranial lesions to facilitate extend of surgery, develop better treatment protocols, and improve the prognosis of a wide array of neurosurgical diseases. More specifically, for the patients who are undergoing surgical intervention for the treatment of their brain aneurysm, tumor, arteriovenous malformation or fistula, the investigators will inject the dye intraoperatively to assess for residual aneurysm, tumor or in general residual lesion which must be corrected.
