Although it may seem obvious that the key goals of health care are to preserve health and prolong life, elderly patients often value preservation of function. Undergoing a surgical procedure can be a physiologically demanding endeavor. Previous chapters have explored how physical conditioning in prehabilitation may improve physical functioning and recovery after surgery. Protecting mental faculties and cognition is equally (if not more) important, particularly for older patients who seek to maximize their dignity and functional independence.Although preoperative cognitive screening has been suggested for years, there is growing understanding of how best to a preoperative cognition and strategies to improve and protect brain function perioperatively. 1 Like other medical conditions, the purpose of screening is to identify at-risk patients, which triggers a series of care management tactics to preserve, and potentially improve, cognition after surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
