Abstract Pneumonia is a significant complication of ischemic stroke that increases mortality. Post-stroke pneumonia is defined as newly developed pneumonia following stroke onset. Clinically and chronologically, post-stroke pneumonia is divided into two types of aspiration pneumonia. First, acute-onset post-stroke pneumonia occurs within 1 month after stroke. Second, insidious or chronic-onset post-stroke pneumonia occurs 1 month after the stroke. The mechanisms of pneumonia are apparent aspiration and dysphagia-associated microaspiration. Stroke and the post-stroke state are the most significant risk factors for aspiration pneumonia. The preventive and therapeutic strategies have been developed thoroughly and appropriate antibiotic use, and both pharmacological and nonpharmacological approaches for the treatment of post-stroke pneumonia have been studied rigorously. Increases in substance P levels, oral care, and swallowing rehabilitation are necessary to improve swallowing function in post-stroke patients, resulting in a reduction in the incidence of post-stroke pneumonia in a chronic stage. The stroke must be a cause of aspiration pneumonia.
