Postoperative cognitive dysfunction (POCD) is one of the common postoperative complications that often affects elderly patients and includes a range of domains, may involve oxidative stress and neuroinflammation. The etiology of POCD has not been known till now, but it was shown that the type of surgery and type of anaesthesia (intravenous vs. volatile anesthetics) don&rsquo;t have significant effect on the incidence of POCD, and as a multifactorial disorder it&rsquo;s better to consider factors such as surgery, anaesthesia, in general, also the consequence of them, and patient-related predisposing factors. Also it was shown that the consequent long-term cognitive deficits, as a potentially harmful factor to the human brain, should be avoided. The detailed molecular mechanisms of POSD is also still largely unknown, while the neuroinflammation has been increasingly denoted as one of the core mechanisms for the pathogenesis of POCD. The mast cells-neurovascular unit communication and the inductive effluence of extracellular RNAs on neuroinflammation are some of possible mechanisms. Even though anaesthesia is an essential and generally safe preoperative clinical approach, because the adverse findings on the relation of it with POCD and neuroinflamation, the person that introduces the anaesthetics should be more aware. Because the exact mechanism and the reason of POCD still has not been significantly proved, more research is needed to regulate neuroinflammation and its relationship to cognitive performance.</div> Postoperative Cognitive, Neuroinflammation, Anaesthesia 131 131 http://shefayekhatam.ir/browse.php?a_code=A-10-24-1077&slc_lang=en&sid=1 Hojjat Shadman Zahroodi Hojjat Shadman Zahroodi shademanzh951@mums.ac.ir 100319475328460015851 100319475328460015851 Yes Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Mohammad Mirzaei Mohammad Mirzaei 100319475328460015852 100319475328460015852 No Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Motahareh Mirdoosti Seyedeh Motahareh Mirdoosti 100319475328460015853 100319475328460015853 No Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Sara Abbassi Sara Abbassi 100319475328460015854 100319475328460015854 No Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran Faculty of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran
