Lesion Location Predicts Transient and Extended Risk of Aspiration After Supratentorial Ischemic Stroke

Abstract

Lesions of the insular cortex and the internal capsule are significantly associated with acute risk of aspiration after stroke. Combined ischemic infarctions of the frontal operculum and the insular cortex are likely to cause extended risk of aspiration in stroke patients, whereas risk of aspiration tends to be transient in subcortical stroke.
