Background And Purpose: In a geographically defined population, we assessed incidence and determinants of aphasia attributable to first-ever ischemic stroke (FEIS).
Methods: A 1-year prospective, population-based study among the permanent residents of the canton Basle City, Switzerland, was performed using multiple overlapping sources of information.
Results: Among 188,015 inhabitants, 269 patients had FEIS, of whom 80 (30%; 95% CI, 24 to 36) had aphasia.
