Depression is a known stroke risk factor, but its influence on stroke course depending on gender and age is not clearly defined. The purpose of this study was to determine the impact of previously diagnosed depression on early and one-year mortality in patients with acute ischemic stroke (IS) in relation to gender, age, and concomitant diseases. This study was based on the registry created from the public health insurer in Poland (2009-2020).
