Subarachnoid hemorrhage

Researchers compare two approaches for adults with small unruptured brain aneurysms found by chance: regular imaging surveillance without initial treatment, or immediate endovascular or surgical repair. The trial enrolls 600 adults aged 35 to 75 with aneurysms measuring 2 to 7.9 …

Researchers are testing whether adding tirofiban to standard antiplatelet therapy improves recovery for people whose ruptured brain aneurysm is repaired with a stent. The trial enrolls adults with acute subarachnoid hemorrhage who receive stent-assisted coiling within 72 hours of…

This trial tests whether a simple, non-invasive technique called remote ischemic preconditioning (RIPC) can reduce brain damage after an aneurysmal subarachnoid hemorrhage, a severe type of stroke. The procedure involves briefly inflating a blood pressure cuff on the leg to restr…

This study tests whether a stellate ganglion block (a nerve block injection) can improve neurological outcomes in people who have had a bleeding stroke from a ruptured aneurysm. The procedure is done before surgery to reduce brain artery spasms and improve blood flow. Researchers…

This study tests whether giving aspirin early after repairing a ruptured brain aneurysm helps patients recover better. About 388 adults who had a bleeding aneurysm will receive either aspirin or a placebo for 10–14 days. The goal is to see if aspirin reduces brain complications a…

This study tests a drug called tirofiban (Aggrastat) in 82 people who have had bleeding from a brain aneurysm. The drug is given through a vein to prevent blood clots that can cause delayed brain damage. The main goal is to find the safest dose, while also checking if it reduces …

This study looks at whether giving extra oxygen through a facemask can help people who have had a brain aneurysm bleed and are breathing too fast, causing low carbon dioxide levels. About 80 adults with this condition will receive the oxygen treatment to see if it reduces the ris…

This study tests whether giving magnesium sulfate early through an IV can reduce dangerous narrowing of brain arteries after a traumatic brain bleed. About 50 adults with head injuries will receive the treatment within 24 hours. The goal is to see if it lowers the risk of delayed…

This study tests whether the drug cilostazol can prevent delayed brain injury in people who have had a bleeding stroke from a burst aneurysm. About 316 adults will receive either cilostazol or a placebo for 14 days. The goal is to see if the drug reduces the risk of delayed brain…

This study tests whether adding cilostazol, a drug that improves blood flow, to standard nimodipine treatment helps people recover better after a brain aneurysm rupture. Researchers will enroll 630 adults in France within 96 hours of the bleed and follow them for 6 months. The go…

This study tests whether raising or lowering blood pressure after aneurysm repair improves outcomes in people with a brain bleed. 750 adults who had surgery within 72 hours will be randomly assigned to different blood pressure targets. Their recovery will be tracked for 6 months …

This trial tests whether two non-invasive tools can help paramedics detect dangerously high pressure inside the skull in patients with sudden brain injury, such as stroke or head trauma, before they reach the hospital. The tools are a wearable sensor placed on the head and an ult…

This trial tests whether ticagrelor, an antiplatelet drug, can prevent stroke and delayed brain ischemia in people who have had a low-grade aneurysmal subarachnoid hemorrhage. Participants receive either ticagrelor or a placebo for 14 days, starting just before endovascular treat…

This study tests whether giving a calcium channel blocker (nicardipine) through a lumbar drain can prevent dangerous artery spasms and delayed brain damage in people who have had a brain bleed from a ruptured aneurysm. About 214 adults with mild to moderate bleeds will receive th…

This study tests a new approach to prevent delirium (sudden confusion) in patients with a type of stroke called subarachnoid hemorrhage who are in the intensive care unit. The program combines standard medical care with basic body awareness therapy and video-based communication. …

Researchers test whether infusing lidocaine into the middle meningeal artery reduces headache severity in adults who have had a bleeding brain aneurysm. Participants receive either lidocaine or a saline placebo during their endovascular aneurysm repair. The trial measures headach…

After a severe brain injury, some patients survive but cannot communicate, and it is difficult to predict who will recover consciousness. This observational study in Cyprus is testing whether a brain-wave monitoring technique called the bispectral index (BIS) can improve predicti…

This study investigates why some people develop long-term thinking and memory problems after surgery to repair a ruptured brain aneurysm. Researchers will review past medical records and then bring in 150 adult survivors for brain scans and cognitive tests. The goal is to identif…

This study uses a non-invasive forehead sensor to continuously monitor brain oxygen levels in 120 patients with subarachnoid hemorrhage (a type of stroke caused by bleeding around the brain). The goal is to see how the brain's ability to regulate blood flow changes over time and …

This study tests two strategies for removing an external ventricular drain (a tube that drains fluid from the brain) in 170 adults who had a brain bleed. One method clamps the drain shut as soon as it's safe, while the other gradually raises the drain over time. The goal is to se…

This study tests if a non-invasive device called Electrical Impedance Tomography (EIT) can safely monitor brain blood flow in 100 ICU patients with conditions like stroke or brain bleeding. Currently, doctors must insert a probe into the skull to check this, which can cause infec…

This study will observe 300 adults in the intensive care unit with serious brain conditions like bleeding, stroke, or injury. Researchers will use noninvasive monitors to track brain activity and blood flow, linking this data to patients' recovery. The goal is to better understan…

This study looks at 300 adults with a brain bleed from a ruptured aneurysm. It tests a non-invasive headband to monitor brain blood flow and two nerve treatments (a neck injection and ear stimulation) to see if they improve brain function. The goal is to find better ways to preve…

This study will look at medical records of 170 patients aged 70 and older who were in the ICU for a bleeding stroke called aneurysmal subarachnoid hemorrhage. Researchers want to find out which factors are linked to poor recovery or death six months later. The goal is to help doc…

This study looks at blood markers related to inflammation and clotting in people who have had a stroke or a brain bleed. Researchers want to see how these markers change over time and differ between patients with complications. About 499 adults will give blood samples at five tim…

This study will check how common thinking and memory problems are in people who have had their first stroke. Researchers will evaluate 400 adults aged 18 to 60 within three months of their stroke. The goal is to better understand the impact of stroke on the brain, not to test a n…
