Predictors of Residual Dysphagia After Acute Stroke

Clinical Context and Natural History

Between 11% to 50% of patients continue to experience dysphagia 6 months after stroke, with the initial incidence ranging from 40% to 78% in acute stroke patients, according to the American Heart Association 1, 3

Aspiration due to dysphagia can be "silent" and may go undetected until pulmonary complications manifest, as noted by the American College of Physicians 2
Bedside evaluation alone is insufficient for detecting persistent dysphagia; instrumental assessment is more sensitive, as recommended by the American Academy of Neurology 2
Dysphagia after extubation requires special attention, as older age and duration of intubation are associated with post-extubation dysphagia, which can worsen pre-existing stroke-related swallowing difficulties, according to the American Thoracic Society 1, 2

Persistent dysphagia leads to stroke-associated pneumonia, malnutrition, dehydration, increased mortality, and impacts discharge location and quality of life, as reported by the American Stroke Association 1, 3, 2
