The tell-tale signs of a person’s susceptibility to a stroke may appear up to 10 years before the event, suggests research published online in the Journal of Neurology Neurosurgery & Psychiatry. Stroke patients experienced much steeper declines in cognitive abilities and routine daily functioning, starting around a decade before their first stroke, than people who didn’t have a stroke,…
A study involving virtual rather than real patients was as effective in evaluating a medical device used to treat brain aneurysms, according to new research. The findings are proof of concept for what are called in-silico trials, where instead of recruiting people to a real-life clinical trial, researchers build digital simulations of patient groups, loosely akin to the way virtual…
After a stroke, doctors can try to remove clots in blood vessels to keep blood flowing freely to the brain. But even though most of these procedures are successful, less than half of people have a successful recovery from the stroke. A new study published in the medical journal Neurology sheds light on why that may be. The study found that trying more than once during a procedure to retrieve a…
A new positron emission tomography (PET) radiotracer can detect abdominal aortic aneurysms (AAAs) and potentially predict when they will rupture, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. Targeting a novel biomarker associated with AAA, the radiotracer is effective both in diagnosis and in providing information to assist in the…
