Identifying risk factors, understanding the pathogenesis (especially reperfusion injury), and implementing early intervention are crucial. However, the complex etiology and limited efficacy of drug treatments make early detection and management challenging. Recent studies have identified factors such as age, NIHSS score, pre-stroke cognition, and post-reperfusion inflammation, along with biomarkers, as predictors of delirium. Family involvement and environmental optimization may also reduce risk. This review summarizes current evidence on risk factors, pathogenesis, biomarkers, and interventions to improve early identification, reduce disability, and improve prognosis.
