Abstract
Perioperative neurocognitive disorder (PND) is a cognitive dysfunction that often occurs after surgery, particularly in elderly patients. The cerebral lymphatic system, which acts as an immune scavenger for the nervous system, may play a crucial role in the development of PND. Recent studies suggest that microglia, by sensing metabolites of ATP (adenosine triphosphate), inhibit neuronal electrical activity. This inhibition may impact the driving force of the cerebral lymphatic system and impair its scavenging function. Investigating the role of microglia in regulating the cerebral lymphatic system through the ATP-AMP (adenosine monophosphate)-ADO (adenosine) pathway could provide new insights into the pathogenesis of PND and identify novel targets and strategies for its prevention and treatment.
