Abstract
A method for determining changes in brain blood circulation, including: recording signals from a single side of a neck; processing the recorded signals; determining hemodynamic changes in brain blood circulation indicating abnormal blood circulation at a contralateral side, based on results of the processing.

A system for determining changes in brain blood circulation, comprising:
- at least one sensing unit configured to be positioned at a side of a neck, comprising at least one pulse wave detector for measuring pulse waves;
- a control unit functionally coupled to said at least one sensing unit, comprising:
- a memory circuitry;
- a control circuitry configured to receive said pulse wave measurement, to process said pulse wave measurements, and to determine hemodynamic changes in brain blood circulation indicating abnormal blood circulation at a contralateral side based on said processing results.

A device for detecting an ischemic event in a subject, comprising:
- a memory circuitry, wherein said memory circuitry stores pulse waves measurements;
- a control circuitry, wherein said control circuitry is configured to extract features comprising morphological features and/or time based features, from said pulse waves measurements, and to identify changes in brain blood circulation indicating a pending ischemic event based on said extracted features.
