Multimodal Neuroprotection in Ischemic Stroke: Emerging Non-Pharmacological Interventions from Bench to Bedside

Currently, the effective therapeutic strategies for acute ischemic stroke (AIS) remain revascularization therapies, including intravenous thrombolysis and endovascular thrombectomy. However, the narrow time window and reperfusion injury associated with reperfusion therapy limit favorable outcomes in some patients. As adjuncts to revascularization, certain neuroprotective agents have demonstrated robust preclinical results, but only a few have achieved successful clinical translation due to challenges in dosing and safety concerns. In recent years, convenient and relatively safe non-pharmacological neuroprotective interventions—such as hypothermia, remote ischemic conditioning (RIC), and normobaric hyperoxia (NBO)—have gained increasing research attention. These approaches offer advantages including high safety profiles, excellent tolerability, low cost, and the potential to synergize with reperfusion therapy, underscoring their broad clinical applicability. Numerous clinical trials have validated their potential to improve neurological functional outcomes, and this review explores the mechanisms and clinical applications of non-pharmacological neuroprotective therapies in ischemic stroke.
