Stroke is the 2nd leading cause of death and disability worldwide. When it happens, 2 million neurons die every minute. However, even non-specialized caregivers do not know how to recognize a stroke, so lots of time is lost at diagnosis. Even in the US, 40%+ of ischemic stroke patients arrive too late for effective treatments. AI-Stroke is leveraging advanced AI and ML to enable earlier and easier stroke diagnostics for EMS first responders. AI-Stroke has created the world’s largest dataset of stroke patient videos, with over 23,000 videos and 4.5 million images, to train its AI. Embedded in a tablet or smartphone, it is a tool designed for EMS first responders (e.g., ambulances, 911 operators & emergency rooms) to identify strokes and large vessel occlusion in seconds. Patients perform exercises while being filmed, and the AI gives stroke diagnostics, specifies its kind, and selects the best hospital for treatment, significantly shortening the time to treatment and saving the lives of stroke patients.
