Perioperative neurocognitive disorders: the importance of global systemic interactions

Listen to this summary

This review article addresses the question of how perioperative neurocognitive disorders (PNDs) develop, particularly in older adults, and highlights the need for a deeper understanding of the systemic interactions that contribute to these cognitive impairments following anesthesia and surgery. The authors emphasize the potential role of extrasynaptic GABA<sub>A</sub> receptors in PNDs and advocate for a more integrated approach to studying the various factors influencing cognitive function, which may lead to more effective prevention and treatment strategies.
