<ul><li>A team of scientists in America have created a non-invasive headset to track changes in blood flow and assess a patient's stroke risk.</li><li>The device could detect early signs of a stroke.</li><li>The most common cause of stroke is a blood clot blocking an artery to the brain.</li><li>Physicians use a questionnaire to estimate a patient's risk of a stroke, although these methods have limitations.</li><li>The need remains for tools that can proactively monitor and quantify stroke risk before an event occurs.</li><li>In a new study, a headset device was developed to monitor changes in the brain's blood flow and volume while a patient holds their breath.</li><li>The device is portable and cost-effective and measures changes in blood volume by reflecting infrared light through the skull and brain.</li><li>The researchers tested the device on 50 patients, dividing them into low- and high-risk groups based on their stroke-risk calculator.</li><li>The team plans to expand the studies to a broader population.</li><li>The researchers believe their technology could also be applied to other neurological diseases.</li></ul>
