Objectives:
Stroke symptom recognition is critical in reducing time to treatment, but it is not known whether the increased support for stroke education programs during the last several years has led to an improvement in regional stroke symptom recognition levels since they were last assessed in the mid-2010s.
Methods:
We used the most current estimates of recognition from the 2017 National Health Interview Survey to examine regional recognition levels for individual stroke symptoms and correct identification of all five stroke symptoms.
Results:
Recognition of individual stroke symptoms was ≥76% in all regions, but correct identification of all stroke symptoms was lower ranging from 68.8 to 70.2%. Recognition of sudden numbness or weakness of face, arm, or leg, especially on one side (Northeast: 94.9%, Midwest: 95.8%, South: 93.8%, West: 94.5%) was the highest and recognition of sudden headache with no known cause (Northeast: 77.6%, Midwest: 76.4%, South: 77.7%, West: 76.5%) was the lowest for all regions.
Discussion:
We observed similar stroke symptom recognition levels in each US region with little improvement since the mid-2010s. Additional effort should be made to increase recognition of sudden headache with no known cause in US regions with current high prevalence of stroke risk factors.
