New research has shed light on why restoring blood flow after an ischaemic stroke does not always lead to neurological recovery. The study suggests that the brain’s own protective response can contribute to the formation of tiny blood clots in smaller vessels, potentially causing continued tissue damage even after the main clot has been removed….

New European stroke action plan urges immediate national action
European governments are being urged to take rapid and decisive action on stroke care following publication of the updated Stroke Action Plan for Europe in the European Stroke Journal. The plan calls for the implementation and proper funding of comprehensive national stroke strategies aligned with its evidence-based recommendations, warning that further delays will cost lives…
Stem cell therapy study reveals how transplanted neurons navigate the injured brain after stroke
A new study has provided insight into how stem cell derived neurons can survive, integrate and restore function in the brain following stroke, addressing a major challenge in regenerative neurology. Researchers from Sanford Burnham Prebys Medical Discovery Institute and Duke-NUS Medical School report that transplanted human stem cell derived neurons possess intrinsic molecular codes that…
Global Stroke Action Coalition calls for urgent action to address stroke crisis
The world’s first multisector advocacy movement dedicated to stroke – the Global Stroke Action Coalition – has issued an urgent call to action to address growing inequities in stroke. Already a leading cause of death and disability, without intervention, the global burden of stroke is projected to rise by a further 50% over the next…
Detecting large vessel occlusion (LVO) using AI
Recent data from a large-scale comparative study indicate that RapidAI’s artificial intelligence (AI) platform demonstrates higher sensitivity in detecting large vessel occlusion (LVO) compared to Viz.ai’s software. The study, DUEL (Detection of LVO Using AI), represents the largest head-to-head evaluation to date, including 1,591 consecutive patients presenting with suspected stroke. Findings from this study, along…
Study likely to change standard of care for vertebrobasilar stroke
14 January 2025: Endovascular therapy, or EVT – a minimally invasive surgery performed inside the blood vessels – is 2 ½ times more likely than standard medical management to achieve a positive outcome after vertebrobasilar stroke that affects the back of the brain, including the brain stem. A meta-analysis of four randomised clinical trials, published…
New AI stroke brain scan readings are twice as accurate as current method
New AI software can read the brain scans of patients who have had a stroke, to more accurately pinpoint when it happened and help doctors work out whether it can be successfully treated. The software, devised by researchers from Imperial College London, Technical University of Munich, and Edinburgh University, addresses two of the most difficult…
New mechanism for blood flow regulation in the brain
19 December, 2024: A study led by Mark Nelson, PhD, from the Larner College of Medicine at the University of Vermont, has identified a new mechanism, Electro-Calcium (E-Ca) Coupling, that integrates electrical and calcium signalling to regulate blood flow in the brain. Published in PNAS, the research redefines how capillaries ensure precise oxygen and nutrient…
‘Access to Health’ to improve stroke care in Africa
New initiative from Merz Therapeutics and World Stroke Organization October 24th, 2024: at the annual World Stroke Congress in Abu Dhabi, the President of the World Stroke Organization (WSO), Dr. Sheila Martins, officially announced a partnership with Merz Therapeutics to launch the ‘Access to Health’ initiative. This project, focusing on addressing healthcare disparities in low-…
Position of stroke patient’s head before surgery may improve neurological function
Research Highlights: from American Stroke Association International Stroke Conference, February 2024 Positioning patients with large vessel ischaemic (clot-caused) stroke with their heads flat (0-degrees) before surgery to remove the blood clot resulted in significant improvements in neurological function, compared to patients whose heads were elevated (at a 30-degree angle), according to science presented on February…
