They believe the device, currently just a prototype, will allow them to detect future strokes in patients who have recently experienced one and are thought vulnerable to another attack.

The device is fitted on to a patient's head and monitors their brain waves.

Its creators say it provides medical personnel with real-time information, allowing them to diagnose and treat high-risk patients in time to prevent or minimize potential brain damage.

Israel company neurokeeper says the device uses an algorithm to identify and locate the stroke.

"Our device detects automatically a stroke event and alerts either in the home environment the patient himself or his family, or in the hospital environment the medical staff, of a potential ischemic attack and allows the patients to get to the hospital early and get treated early," Shay Bar-Haim, a neurokeeper, said.
