Education and Literacy as Risk Factors of Dementia after Stroke and Transient Ischemic Attack: NEDICES Study.

The differential role of literacy and education on dementia after stroke remains unexplored. Objective:This research addresses the role of education and literacy in dementia incidence after stroke and transient ischemic attack (TIA). Methods:131 participants with stroke or TIA were identified within the population-based NEDICES study (N = 5,278 persons). Participants were fully assessed at baseline (1994–1995) and incident dementia diagnosis was made by expert neurologists (DSM-IV criteria) after a mean follow-up of 3.4 years. Adjusted Cox regression analyses were applied to test the association between education, literacy, and dementia risk. Results:Within the 131 subjects with stroke or TIA, 19 (14%) developed dementia at follow-up. The Cox’s regression model (age and sex adjusted) showed that low education (HR = 3.48, 95% CI = 1.28, 9.42, p = 0.014) and literacy (HR = 3.16, 95% CI = 1.08, 9.22, p = 0.035) were significantly associated with a higher dementia risk. Low education was also associated with dementia when main confounders (i.e., cognitive/functional performance) were considered in the Cox’s model. However, after including stroke recurrence, only low/null literacy (versus education) remained as significant predictor of dementia. Finally, low/null literacy showed an effect over-and-above education on dementia risk when both factors were introduced in the adjusted Cox’s regression. Conclusion:These findings underline the importance of literacy to estimate cognitive decline after stroke in low-educated populations. 2024-01-12T10:41:12Z 2024-01-12T10:41:12Z 2024-01-12T10:41:12Z 2022-06-28 info:eu-repo/semantics/article Contador, I., Alzola, P., Bermejo-Pareja, F., Del Ser, T., Llamas-Velasco, S., Fernández-Calvo, B., & Benito-León, J.
