Noninvasive Device Offers New Method for Detecting Stroke Risk

When it comes to measuring an individual’s risk of stroke, current assessment for the general population relies on markers such as demographics, blood tests, and comorbidities. Now, a team of engineers and scientists from Caltech and the Keck School of Medicine of USC have developed a headset-based device that can be used to assess a patient's stroke risk, offering a minimally invasive, clinically scalable, and cost-effective option.

The device works by monitoring changes in blood flow and volume while a participant holds their breath. It incorporates a laser-based system and has shown promising results in terms of differentiating between individuals at low and high risk of stroke.
