A team of researchers has developed a promising new method for measuring stroke risk. This non-invasive device, which uses speckle contrast optical spectroscopy for early stroke detection, akin to a cardiac stress test, could revolutionize stroke care by enabling early detection and prevention.
Strokes, a leading cause of neurological disability, occur when blood flow to the brain is disrupted. Currently, there are limited options for screening patients for physical signs of increased stroke risk. Healthcare providers rely primarily on indirect markers such as lifestyle and family history.
The new device, worn like a headband, utilizes speckle contrast optical spectroscopy (SCOS). This technique uses lasers and cameras to measure blood flow and volume in the brain. In a proof-of-concept study, researchers found that the SCOS device could differentiate individuals with high stroke risk from those with low risk based on changes in blood flow during a breath-holding stress test.
This affordable and portable device could significantly impact stroke prevention if validated through further research. It could help healthcare providers assess a patient’s risk, tailor treatment plans, and potentially prevent strokes before they occur. The researchers envision the device becoming a standard part of annual physical exams.
While more research is needed, the potential of this new technology is promising. Providing a simple and effective way to assess stroke risk could save countless lives and improve the quality of life for millions of people.
