Key result
Postoperative cognitive dysfunction is a recognized complication after surgery and anesthesia, with risk factors including older age, lower education, and postoperative delirium, though current studies lack standardized methodology.
This review highlights that while correlates and risk factors for postoperative cognitive dysfunction are known, its true incidence, etiology, prevention, and treatment remain to be fully elucidated.
Risk factors warrant perioperative awareness in older patients; leaves open standardized assessment of incidence, etiology, and prevention.
Postoperative cognitive dysfunction (POCD) refers to a deterioration in cognition noted to occur after surgery and anesthesia. Recent studies have demonstrated a number of correlates and risk factors for this condition, although much remains to be elucidated in terms of the true incidence, etiology, prevention, and treatment.
