- Scientists in Hong Kong have developed the world's first nasal spray designed to protect brain cells immediately following a stroke.
- The "Nanopowder" spray delivers brain-protective drugs directly to the brain by bypassing the blood-brain barrier via the nose-to-brain pathway.
- Administering the spray within 30 minutes of stroke onset can reduce brain tissue death by over 80 per cent and protect neurological and body movement functions.
- This innovation aims to provide early protection en route to the hospital, significantly slowing cell death and extending the crucial therapeutic window for stroke treatment.
- Researchers believe this could be a breakthrough solution for prehospital emergency stroke treatment, shifting intervention from an in-hospital to an earlier stage.
