Abstract
System and Method to detect an abnormal medical event based on an asymmetrical change to blood flow. The system includes right-side and left-side head-mounted devices to measure signals indicative of photoplethysmographic signals (PPG signals) on the right and left sides of a user's head, and a computer that detects the abnormal medical event based on an asymmetrical change to blood flow recognizable in the PPG signals. Optionally, the asymmetrical change to the blood flow corresponds to a deviation of the PPG signals compared to a baseline that is based on previous measurements of PPG signals of the user, taken before the abnormal medical event.
