With the aging of the population, the incidence of stroke is increasing year by year. More than 50% of stroke patients have post-stroke dysphagia, which not only increases the risk of complications such as aspiration pneumonia, malnutrition and dehydration, but also is associated with poor prognosis and increasing mortality. Due to its high morbidity and high risk of complications, the European Stroke Organization and the European Society for Dysphagia have launched the guideline for the diagnosis and treatment of post-stroke dysphagia (2021 Edition). This guideline mainly raises questions about the screening, assessment, and treatment of post-stroke dysphagia, and answers them based on evidence-based medical evidences. This article mainly interprets this in order to better guide clinical practice.
