The growth of brain health initiatives in the United States and worldwide has led to a movement to protect the brain from avoidable injury across the lifespan. With the advancement of our armamentarium of neurologic treatments and preventives during the past several decades, the field of preventive neurology has spawned. Under the umbrella of preventive neurology is perioperative brain health, an under-addressed but important topic in the field of neurology. Perioperative brain health is important because perioperative mortality may be relatively high, and morbidity as quantified by brain injury biomarkers (e.g., MRI brain) and clinical phenotypic manifestations related to stroke can be common. In this perspective, in relation to periprocedural stroke, we review the stroke mechanisms, epidemiology and risk factors, risk stratification measures and long-term outcomes, and potential mitigation and treatment opportunities. As perioperative brain health crosses many medical disciplines, multidisciplinary action is needed to bridge the knowledge gaps and reduce brain injury and attendant neurologic complications. Anesthesiologists and other healthcare professionals working in the surgical and procedural field are well-positioned to make important contributions to this growing discipline of the prevention of brain injury in the perioperative period.
Qureshi et al. (2026) studied this question. Periprocedural stroke and perioperative brain injury represent common sources of morbidity and mortality that require multidisciplinary mitigation and treatment strategies.
