Dynamic functional reorganization in post-stroke aphasia: a state-of-the-art fMRI review from disease evolution to intervention

Post-stroke aphasia (PSA) is a common and disabling consequence of stroke, characterized by substantial heterogeneity in language impairment and recovery trajectories. In recent years, functional magnetic resonance imaging (fMRI) has markedly advanced our understanding of the neural mechanisms underlying PSA recovery by revealing dynamic changes in regional activation, functional connectivity, and large-scale network coordination. This review provides a state-of-the-art synthesis of fMRI studies
