El estudio consistió en entrevistar telefónicamente a más de 61.000 adultos estadounidenses. Sólo el 17% identificó correctamente todos los signos del ictus y explicó lo que se debe hacer cuando existe sospecha de que una persona experimenta un accidente cerebrovascular.
También revela que los fumadores demuestran tener mayor desconocimiento al respecto que los no fumadores. Tampoco conocen bien los signos del ictus las minorías étnicas, las personas más jóvenes y las de edad más avanzada.
