Stroke is a leading cause of mortality, disability and there are substantial economic costs for post-stroke care. Stroke-associated pneumonia (SAP) is an important cause of post-stroke morbidity and mortality. It is a common post-stroke complication, affecting approximately 14% of patients with stroke. Stroke patients suffer from many risk factors for pneumonia such as dysphagia, aspiration, stroke-induced immunodepression syndrome, immobility due to paralysis, impaired consciousness ...

The diagnosis of SAP faced many difficulties due to the characteristics of stroke patients: fever, decreased cough, altered mental status, leukocytosis with a left shift ...
