Every year, thousands of patients arrive at emergency departments with symptoms of head injury or stroke. Doctors must make rapid decisions about imaging and transfer based only on symptoms, which often look the same whether the issue is serious or not. Most patients appear stable and turn out to be fine, but the few that aren’t can deteriorate quickly, and there is no fast, objective way to identify them early. Cerebra Sensing is building a wearable device that gives clinicians real-time insight into what’s happening in the brain, helping them detect patients at risk of a brain bleed and make better decisions, sooner.
