Brain ischemia

This trial compares two medications, ephedrine and phenylephrine, used to treat sudden low blood pressure during carotid surgery. The main question is whether one drug better preserves oxygen levels in the brain during the procedure. The study involves adults undergoing planned c…

This study tested whether the drug rivaroxaban works as well as warfarin to prevent further brain damage in people who have had a stroke due to antiphospholipid syndrome (APS), a condition that causes abnormal blood clotting. About 40 participants took either rivaroxaban or warfa…

This completed study tested a new device called the Supernova stent retriever in 55 people with severe stroke caused by a large blood clot in the brain. The device is threaded through blood vessels to grab and remove the clot, restoring blood flow. Researchers measured how often …

This study tested a clot-dissolving medicine called alteplase in 58 people who had a stroke caused by a blocked artery. The goal was to see how well it reopened blocked brain arteries and improved patients' ability to function three months later. The results were compared to exis…

This study tested a lower dose (0.6 mg/kg) of the clot-busting drug alteplase in 103 Japanese patients who had a stroke within the previous 3 hours. The goal was to see if this dose was both safe and effective for this population. Results focused on how many patients had little t…

This study tested whether adding Mexidol to standard stroke care helps people recover better after a first ischemic stroke. 304 adults who had a stroke within 48 hours were given either Mexidol or a placebo for about 10 weeks. Researchers measured disability, neurological symptom…

This study tested whether tiopronin, a drug used for liver disease, can lower a harmful chemical in the brain and improve recovery after a bleeding stroke from a burst aneurysm. Sixty patients received either tiopronin or a placebo for up to 14 days. The goal was to see if the dr…

This study tested whether the drug Mexidol (given first as injections, then as pills) can improve thinking and memory in people with chronic cerebral ischemia, a condition where the brain doesn't get enough blood flow. 318 adults aged 40-90 with mild to moderate cognitive impairm…

This study tested a 6-month program for 92 stroke survivors in Vietnam. The program included regular health checks, personalized rehabilitation exercises, and motivational interviewing to support mental health. Participants were compared to those receiving standard care. The goal…

This study aims to understand if COVID-19 vaccines have any impact on brain health in healthy people. Researchers will use MRI scans to look for changes in the brain's blood vessels and structure. The study will follow 500 adults from Hong Kong who have already had a baseline bra…

This study followed 67 children with sickle cell disease who had a high risk of stroke. Researchers compared those who received a bone marrow transplant to those who got standard care, checking brain scans and thinking skills 9-10 years later. The goal was to see which approach b…

This study looked at whether using best-practice physical therapy and giving stroke survivors an activity monitor can help them walk better. About 306 people who had a stroke and were in rehab took part. The main goal was to see if they could walk farther in 6 minutes after the p…

This completed study looked at 192 adults with acute ischemic stroke to see if large swings in blood sugar (glycemic variability) are linked to worse outcomes, including death and disability. Participants wore a continuous glucose monitor for 96 hours. The goal was to understand …

This study followed 82 people with blocked arteries supplying the back of the brain to see if low blood flow raises the risk of stroke or mini-stroke. Participants had already experienced a stroke or transient ischemic attack (TIA) and had at least 50% blockage in those arteries.…

This study used artificial intelligence to learn the patterns of reduced blood flow to the brain during planned surgeries. 60 patients having carotid artery surgery or stroke clot removal were monitored with non-invasive devices. The goal was to teach AI to recognize these patter…

This study aimed to better understand why some people develop delayed brain damage after a brain aneurysm rupture. Researchers measured platelet activation over time in 90 patients, comparing those with aneurysm bleeds to those with other types of brain bleeds. The goal was to cl…

This completed study followed 229 stroke survivors over time to understand what factors might lead to dementia or cognitive problems after a stroke. Researchers looked at medical history, brain scans, and medications. The goal was to identify clues that could help predict and pos…

This study looked at 366 people who had a brain bleed from a burst aneurysm. Researchers measured hemoglobin in the fluid around the brain and spine to see if it could predict secondary brain injury, like artery spasms or lack of blood flow. The goal is to find a better way to mo…
