Active clinical trials for "Brain Ischemia"

This observational study focus on a new parameter of cerebral perfusion derived form digital substraction angiography.

The goal of this study is to develop a large longitudinal cohort of individuals diagnosed with or at high risk for brain diseases (both neurological and psychiatric in nature), in order to identify risk factors that contribute to neurological and psychiatric diseases over time. The investigators seek to capture relevant information from medical records, electronically administered questionnaires and follow up phone-based interviews. The investigators expect to eventually have sufficient power from our dataset to examine risk factors for a variety of brain disorders, both individually and in aggregate. Our ultimate goal is to offer scientifically validated ways to preserve and promote brain health by working with our patients' needs and tracking their progress over time.

The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.

This will be a five year study that will be a prospective, randomized, controlled trial (RCT) to assess the effect of a virtual early intervention care delivery model in the provision of therapy to enhance the neurodevelopmental trajectory of infants with brain injury. In addition, the investigators will enhance understanding of the social and parental contributors to outcomes and the early health economic impact of a virtual clinic. The results of this study will help inform the design of a larger, multi-center randomized controlled trial.

The investigators will test the central hypothesis that DFO treatment after SAH may improve cerebrovascular regulation, mitigate ischemic neural injury, and serve as an effective neuroprotectant against delayed ischemic injury after SAH.

The aim of the study is to determine if 2-week repetitive transcranial magnetic stimulation at the subacute phase of stroke (between day 7 and day 14) improves significantly arm motility at 3 months with remaining effect at one year, without significant adverse effect.

The purpose of this study is to test the feasibility of a trial on induced hypertension to improve neurological outcome in patients with subarachnoid haemorrhage that developed the serious complication "delayed cerebral ischemia", and to assess whether induced hypertension results in improved cerebral blood flow (CBF) as measured by means of perfusion-CT.

Cardiac surgery is associated with risk of perioperative inflammation and ischemia leading to cerebral and myocardial morbidity and mortality. Ischemic preconditioning by repetitive ischemic episodes at an organ can reduce damage resulting from consecutive prolonged ischemia in that organ. Remote ischemic preconditioning is defined as ischemic preconditioning by repetitive ischemic episodes of an organ remote from the organ to be protected, e.g. ischemic episodes of a limb can reduce ischemic damage of the heart. Animal studies as well as human studies have shown that ischemic preconditioning can protect the heart from intraoperative ischemia. Remote preconditioning by repetitive limb ischemia has been applied in humans in some studies.12-14 However, the published data is not yet sufficient to support evidence based recommendations for clinical practice. In particular, available data regarding the influence of remote preconditioning on inflammatory and ischemic damage of brain and heart in children following surgery of congenital heart disease are limited. Hence, this prospective, controlled and randomized study was designed to perform remote ischemic preconditioning in children after induction of anesthesia for pediatric heart surgery and to investigate the effect on postoperative organ function in comparison to a control group.

The Optimizing Cooling trial will compare four whole-body cooling treatments for infants born at 36 weeks gestational age or later with hypoxic-ischemic encephalopathy: (1) cooling for 72 hours to 33.5°C; (2) cooling for 120 hours to 33.5°C; (3) cooling for 72 hours to 32.0°C; and (4) cooling for 120 hours to 32.0°C. The objective of this study is to evaluate whether whole-body cooling initiated at less than 6 hours of age and continued for 120 hours and/or a depth at 32.0°C in will reduce death and disability at 18-22 months corrected age.

The primary purpose of this study is to determine whether a brief intravenous infusion of ancrod started within 6 hours of stroke onset improves functional outcome at 3 months.
