Perioperační neurokognitivní porucha - advanced narrative review.

Term postoperative cognitive disorder stands for deterioration of cognitive function after surgery in postoperative period. Evaluation and diagnostics of cognitive disorders in perioperative period were highlighted by the increasing number of geriatric patients undergoing a surgery with general anaesthesia, with the goal of fast recovery and preservation of the quality of life. Deterioration in cognitive function after surgery was originally called postoperative cognitive dysfunction. The definitions of postoperative cognitive dysfunction varied. In order to unite them, in 2018 there were published new recommendations during which the postoperative cognitive dysfunction was replaced by the term perioperative neurocognitive disorder. This was divided based on different time frames of onset to pre-existing neurocognitive disorder, postoperative delirium, delayed neurocognitive disorder and (postoperative) neurocognitive disorder. Main goals of this advanced narrative review were description of terminology, identification of risk factors, prevention, and therapy of perioperative neurocognitive disorder. [ABSTRACT FROM AUTHOR]
