New Helmet Saves Time in Stroke Diagnosis
Scientists from Chalmers University of Technology, Sahlgrenska Academy, and Sahlgrenska University Hospital in Sweden have presented clinical evidence that a helmet able to generate and analyze microwaves can quickly distinguish the type of stroke. A stroke resulting from a ruptured blood vessel can be differentiated from a stroke caused by a blood vessel blocked by a loose clot. Since clots can be dissolved by therapeutic drugs, treatment of this class of strokes (85% of all strokes) can begin as soon as the diagnosis is made. The helmet has no effect on the other class of strokes. Time is important. Stroke-caused deaths and disabilities are fewer with earlier treatment. The clinical studies on the helmet were done in a hospital, but the helmet is designed for use in the ambulance. (Full story)
