Objectives: Stroke knowledge is poor in the general population worldwide. Yet, data from Spanish-Speaking populations, particularly in Latin America, are scant. We aim to evaluate stroke awareness using personal interviews in a population-based study. Materials and Methods: A questionnaire of stroke awareness was administered to a randomly selected sample of households. “Good stroke knowledge for action” was defined as recognition of impaired strength, sensation and language plus intention to seek urgent medical attention in a hypothetical stroke situation. Demographics, the term to name stroke, recognition of warning signs and attitude towards seeking medical attention were compared between individuals with and without “good stroke knowledge for action”. Results: From 1986 respondents (87%, median age 59 years [IQR 23], 50.7% female), most recognized stroke as ACV (cerebrovascular accident, [63%]). Weakness/decreased sensation were recognized as stroke warning signs by 83.5% of respondents, followed by aphasia (77.9%), incoordination (71.6%) and headache (70.5%). Chest pain was misclassified as stroke warning sign by 25% of subjects. In a hypothetical stroke situation, most respondents would go to the hospital (52.3%), or activate the EMS (39%). Individuals with a good stroke knowledge for action (63.5%) recognized visual symptoms (60.4% vs 43.8, p<0.0001), incoordination (78.8% vs 34.4%, p<0.0001) and headache (70.5% vs. 57.8%, p<0.0001) more frequently, and were less likely to misrecognize chest pain as stroke warning sign (23.8% vs. 28.9%, p=0.015). Neither, age (OR 1 CI 0.99–1.00, p=0.94), gender (OR 0.95, CI 0.79–1.16, p=0.61) or race (OR 1.17, CI 0.97–1.42, p=0.097) predicted good stroke knowledge for action. Conclusions: Most people recognize stroke as ACV. The recognition of stroke warning signs and the attitude towards seeking emergent medical attention appears acceptable. Yet, most respondents would go directly to the hospital avoiding the EMS.
