This document discusses, among other things, systems and methods for detecting stroke. A system may comprise a sensor circuit for sensing a physiological signal, and a second sensor to detect a physical state change. The physical state change may include a transition in physical activity, posture, or sleep state. A stroke risk circuit may detect, from the sensed physiological signal, a signal indicative of blood pressure surge (BPS) in response to one or more physical state changes. The system may generate a stroke risk indicator indicating a risk of developing an impending stroke event using the detected BPS. The system includes an output unit that outputs the stroke risk indicator to a user or a process. |
