Language Functional Changes after Ischemic Stroke.

Language function after ischemic stroke remains controversial. Lesion location was thought to be the main determinant of aphasia. However,some studies have shown inconsistencies between clinical manifestations and imaging findings,thus challenging the classic anatomy of aphasia. In addition,language reorganization after ischemic stroke is poorly understood,especially the role of the non-dominant hemispheric homologous language area plays in the rehabilitation of aphasia. In this review,by focusing on the localization of language functional area and the role of non-dominant hemispheric homologous language area in the rehabilitation of aphasia,we try to elucidate the functional changes after ischemic stroke and provide theoretical basis for its rehabilitation.
