Time is brain — every minute a stroke is untreated, about 1.9 million brain cells die. Clot-removal procedures (thrombectomy) now help patients up to 24 hours after symptoms start in carefully selected cases, and research is pushing that window further while testing new ways to protect the brain and rebuild function.
What's actually going on in research
Studies are testing improved clot-busting drugs, neuroprotective treatments to limit damage in the first hours, and rehabilitation tools including brain stimulation, robotics, and intensive therapy programs. Research also focuses on preventing second strokes, treating brain bleeds, and on mobile stroke units that bring CT scanners and treatment to the patient.
Better clot removal
Mechanical clot-removal is being tested in more patients, including those with smaller strokes and those who arrive later. Devices are also getting safer and faster.
Recovery and rehab
Trials are testing brain stimulation, robotic devices, and intensive therapy to help survivors regain movement, speech, and independence even months or years after a stroke.
Prevention
Research is comparing newer blood thinners, atrial fibrillation screening with wearables, and treatments for narrowed arteries to lower the chance of a second stroke.
What to know before you search
Eligibility usually depends on stroke type (clot or bleed), how long ago it happened, brain imaging results, and current level of disability.
What types of trials are currently open
- Treatment trials — Testing new drugs or procedures during the acute stroke to limit damage and improve recovery.
- Device trials — Studies of new clot-removal devices, brain stimulators, or rehabilitation robotics.
- Rehabilitation trials — Testing therapy programs designed to improve movement, speech, swallowing, or thinking after a stroke.
- Prevention trials — Testing medications, monitoring, or procedures meant to lower the chance of a first or second stroke.
- Observational studies — Following stroke survivors over time to understand long-term recovery and risk factors.

Hemorrhage Stroke Decision Making Model Based Deep Learning (BrainHemoAI System)
Although hemorrhagic stroke also has the characteristics of high mortality and disability rates, and constitutes a major public health problem worldwide, there is a relative lack of in-depth research teams for hemorrhagic stroke in China. The current preoperative imaging evaluation of spontaneous cerebral hemorrhage is still limited to the traditional Tada formula, and there are subjective differences in diagnosis among different doctors, making it difficult to achieve homogenization in clinical decision-making. Hemorrhagic stroke is a common and frequently occurring disease in Jiangxi Province. Therefore, establishing a new diagnosis and treatment system focused on hemorrhagic stroke can not only fill the research gap in this field in China, improve the accuracy and homogeneity of hemorrhagic stroke diagnosis and treatment, but also promote related research progress to reduce the mortality and disability rates of this disease and improve the clinical prognosis of patients.
LEXURE for Post-Stroke Aphasia: A Randomized, Evaluator-Blinded, Confirmatory Trial
This study evaluates the efficacy of digital language rehabilitation using LEXURE for the treatment of post-stroke aphasia. Half of participants will receive structured language training using the LEXURE application, while the other half will receive workbook-based language training as an active comparator.
