Abstract

Perioperative neurocognitive disorders (PNDs) affect a significant number of elderly patients post-surgery, manifesting as memory loss and attention deficits.

  • PNDs involve complex interactions between neuroinflammation, neurotransmitter imbalance, and changes in gene expression.
  • Microglial activation and interleukin imbalance are noted to play critical roles in the development of PNDs.
  • Surgery and anesthesia may disrupt neurotransmitter systems, particularly affecting GABA and NMDA receptors, leading to impaired synaptic plasticity.
  • Gut microbiota imbalances are associated with sustained neuroinflammation and cognitive deficits in the context of PNDs.
  • Potential therapeutic strategies include the use of bioactive compounds and neuroprotective agents to prevent or treat PNDs.
