A bibliometric and meta-analysis in Frontiers in Neuroscience reviewed 241 studies (2000-June 2025) on cannabinoids in ischemic stroke, showing rising research interest and broad neuroprotective effects. Meta-analysis of 26 animal models confirmed cannabinoids significantly reduce brain infarct volume, improve neurological scores, enhance cerebral blood flow, decrease blood-brain barrier permeability, and lower edema. They also mitigate oxidative stress, inflammation, excitotoxicity, and apoptosis. Subgroup results favored intraperitoneal administration and full-course cannabidiol for consistency; isoflurane proved suitable as anesthetic. Key bioactive components like cannabidiol were highlighted. Cannabinoids provide multi-target protection by addressing multiple stroke damage pathways simultaneously. The study, from Chinese institutions, urges high-quality clinical trials to translate these preclinical benefits to human patients, potentially offering new therapies for acute brain injury from stroke. While promising, findings remain preclinical, requiring further validation for safety and efficacy in humans. This underscores cannabinoids' therapeutic potential beyond symptom management, targeting core mechanisms of ischemic damage. Overall, the research supports continued exploration of medical cannabinoids as neuroprotective agents in stroke treatment.
