The link between gut bacteria and delirium: A systematic review

Updated

Abstract

Postoperative delirium (POD) is associated with prolonged hospitalization, mortality, and long-term functional decline.

  • Gut microbiota may play a role in the development of POD.

  • Current evidence linking gut microbiota to POD is heterogeneous and not fully conclusive.
