Prevalence of stroke symptom awareness, National Health Interview Survey, 2009 and 2014. Stroke symptom awareness was assessed with the question, “Which of the following would you say are the symptoms that someone may be having a stroke?” Response options were numbness of face, arm, leg, or side; confusion or trouble speaking; sudden trouble seeing; trouble walking; and sudden severe headache. Analyses were conducted using t test for difference in prevalence from 2009 to 2014 and adjusted for sex, age, race/ethnicity, and education.
