ABSTRACT
Changes in mental function after operation occurs in patients of all
ages. POCD (postoperative cognitive dysfunction) is defined as a
postoperative memory or thinking impairment that has been corroborated
by neuropsychological postoperative testing and is increasingly
recognized as an important complication. The incidence of
POCD varies depending on surgical procedure and age. POCD
may be as high as 20-90% in aged patients and occurs most often in
patients undergoing cardiovascular surgery. The etiology is multifactorial
and is a result of a complex interaction between surgery
and anesthesia. It has been associated with increased morbidity and
mortality, risk of leaving the job and dependency. An assessment
of cognitive function should be completed as a routine in older
patients before and after surgery. The aim of this paper is to describe
the incidence, risk factors, pathophysiology, treatment, preventive
measures and long term consequences of cognitive dysfunction
after surgery.
