Filter by:The purpose of this study is to investigate how visual orientation discrimination and metacognition (i.e., perceptual confidence) are affected by occipital stroke that causes hemianopia and quadrantanopia in adults. This research will provide insight as to how the residual visual system, which not directly damaged by the occipital stroke, processes orientation (assayed in terms of orientation discrimination) and metacognition (by measuring perceptual confidence for orientation discrimination). These measures will be used to refine computational models that attempt to explain how the brain copes with loss of primary visual cortex (V1) as a result of stroke. This knowledge is essential to devise more effective visual rehabilitation therapies for patients suffering from occipital strokes.
The CONNECT: "Developing a learning COmmunity to increase eNgagemeNt and Enrollment in cardiovascular Clinical Trials" is comprehensive, participant-centered learning community that provides tailored education on cardiovascular (CV) health and research participation; connects community members to CV-related research; and disseminates CV-related study findings. The overreaching goal of CONNECT is to improve participation of underrepresented communities in CV research, including as women, Black adults, and Latino adults, through increasing participants' clinical trial awareness, trust in biomedical research, and willingness to participate in clinical trials. CONNECT will use digital and community-engaged approaches to identify and recruit 1000 adults with cardiovascular disease or a cardiovascular disease risk factor to join CONNECT. Participants who join CONNECT will receive tailored educational information on CV health and research participation via text message. Participants will also have the opportunity to be matched to ongoing CV research studies based on basic demographic information and areas of interest. The educational information will be sent to participants for 12 months. The investigators hypothesize that CONNECT will increase participants' clinical trial awareness, trust, and willingness to participate in clinical trials and that the proportion of Black and Latin adults and women enrolled in trials that partner with CONNECT will be higher following the use of CONNECT for recruitment.
The aim of this comparative and reliability study is to highlight a deficit in the use of vibrotactile sensory feedback (haptic effect) in the planning and execution of fine manual dexterity movements after stroke. The investigators will include 3 groups of subjects, 1 group of young healthy subjects, 1 of older subjects matched in age and sex to the group of chronic stroke patients. Participants will take part in clinical tests of fine motor skills and sensitivity and will use a device to assess the key components of manual dexterity, to which vibrotactile sensors will be added. If they so wish, participants will be able to take part in a transcranial magnetic stimulation (TMS) study to assess the facilitation of cortical excitability due to the haptic effect.
Background: Stroke is a leading cause of mortality and disability globally, with acute ischemic strokes(AIS) due to Large Vessel Occlusion (LVO) presenting significant treatment challenges. Mechanical thrombectomy (MT) has emerged as an effective intervention for AIS within an 8-hour window from symptom onset. However, the potential to extend this window up to 24 hours for select patients could revolutionize outcomes for those arriving late at comprehensive stroke centers. This study investigates the efficacy and safety of Cerebrolysin as an adjunct therapy to MT in extended time window and improving patient recovery. Methods: We conducted a multi-center, prospective, randomized study within the Chang Gung Memorial Hospital system in Taiwan, targeting 100 AIS patients eligible for MT beyond the traditional 8-hour window. Participants were randomized to receive either standard care or Cerebrolysin post-MT, initiated within 24 hours of stroke onset and continued for 14 days. The study assessed neurological, neuropsychological, and biomarker outcomes at multiple time points post-stroke to evaluate the effects of Cerebrolysin on recovery. Results: The primary outcome will measure the proportion of patients achieving favorable functional outcomes (modified Rankin Scale 0-2) at 90 days. Secondary outcomes include the impact of Cerebrolysin on secondary hemorrhagic transformation, brain edema, mortality rates, and quality of life. The study aims to provide comprehensive data on the benefits of adding Cerebrolysin to the standard post-MT care, focusing on its potential to protect against reperfusion injuries and maintain blood-brain barrier integrity. Conclusion: By evaluating the role of Cerebrolysin in conjunction with MT, this study aims to extend the therapeutic window for AIS treatment, offering hope for improved outcomes for patients who would otherwise be ineligible for current reperfusion therapies. The findings may pave the way for new guidelines in stroke management, emphasizing the importance of integrated care approaches in enhancing patient recovery.
This is an investigator-initiated, prospective, open-label, single-arm, non-randomized study to assess the safety and feasibility of external active conductive head cooling during endovascular thrombectomy procedures.
The goal of this study is to learn about the acute pupil response to transcutaneous vagus nerve stimulation (tVNS) in stroke survivors and healthy adults. The main question it aims to answer is whether pupil size response is greater with bilateral tVNS compared to unilateral tVNS. Participants will receive tVNS and sham at the outer ear unilaterally and bilaterally in resting condition. The pupil size of the participants will be recorded during tVNS.
Ischemic stroke with high incidence, mortality, disability and recurrence rate, has become the leading threat to the health worldwide. Intracranial atherosclerotic stenosis (ICAS) is commonly associated with ischemic stroke, especially in Chinese residents. Patients with severe ICAS are subject to a very high risk of recurrent stroke events, despite best medical therapy available. Unstable or complex atherosclerotic plaques can lead to plaque ruptures and distal embolisms, thereby increasing the risk of ischemic stroke recurrence. Studies have shown that activation of inflammatory states may play a driving role in the formation and development of atherosclerosis. So far, it remains unclear which are the best treatments for this condition, especially for high-risk patients. Dl-3-n-butylphthalide (NBP) is a Class I novel drug independently developed in China and was officially approved for use in acute ischemic stroke. Preclinical data showed that NBP can act multiple effects of anti-inflammation, antioxidation and anti-apoptosis by suppressing pro-inflammatory factors and upregulating the expression of anti-inflammatory factors. It is still undetermined whether combined therapy with NBP could enhance the curative effect of intracranial atherosclerosis. The primary purpose of this trial is to evaluate the efficacy of butylphthalide in reducing the degree of arterial stenosis and stabilizing plaques in patients with severe symptomatic middle cerebral artery stenosis.
This study intends to construct the goal-oriented integrated intervention model for AIS in-hospital procedure through the spatiotemporal positioning and the P-D-C-A cycle for continuous improvement (FAST model). Then a multicenter, evaluator-blind, cluster-randomized controlled study aims to verify the validity and safety of this FAST model.
The study is a double-blind randomized controlled trial, lasting for 15 days for each participant. Patients with post-stroke dysphagia who receive treatment at the Rehabilitation Department are selected as the study subjects. The patients are randomly assigned to either the experimental group or the placebo group. All patients receive routine rehabilitation therapy and swallowing rehabilitation training, along with enteral nutrition support using Intermittent Oro-esophageal Tube. In addition to these interventions, patients in the experimental group receive transcranial direct current stimulation, while the instruments used for patients in the placebo group only illuminate an indicator light without any actual effect.
The goal of this clinical trial is to compare the differences in feeding amount and nutritional status between ischemic stroke patients using Intermittent Oro-esophageal Tube and Nasogastric Tube. Patients will be randomly divided into an observation group and a control group, all receiving routine rehabilitation treatment. On this basis, the observation group will use Intermittent Oro esophageal Tube for enteral nutrition support, while the control group will use Nasogastric Tube. Researchers will compare changes in daily intake and nutritional status of two groups of patients before and after the study to see if Intermittent Oro-esophageal Tube can improve the feeding amount and nutritional status between ischemic stroke patients compared to Nasogastric Tube
