POSTOPERATIVE COGNITIVE DYSFUNCTION

This study looked at whether certain substances in the blood can signal if someone will have memory or thinking problems after heart surgery. Researchers measured levels of D-amino acid oxidase, D-serine, and serine in 82 adults before and after surgery. They also tested thinking…

This study tested whether giving the sedative dexmedetomidine during open heart surgery can help protect patients' thinking and memory afterward. Researchers measured brain function with a simple test and checked a blood marker of brain injury. The trial included 32 adults having…

This study looked at how two different anesthesia methods—intravenous propofol versus inhaled sevoflurane gas—affect the brain's protective barrier and the risk of confusion after surgery in 154 older adults (age 60+). Researchers measured a protein in the blood that indicates br…

This study looked at 180 older adults (65+) having major abdominal cancer surgery to see if giving fluids based on real-time body signals (goal-directed fluid therapy) helps prevent short-term memory and thinking problems after surgery. Patients received either this personalized …

This study looked at whether a protein called S100B in the blood can help predict memory problems or confusion after surgery. Researchers followed 137 adults having elective surgery, testing their blood and thinking skills before and after the operation. The goal was to see if S1…

This study looked at 90 older adults (ages 65-85) having surgery under minimal-flow anesthesia. Researchers measured changes in thinking and memory using a simple test before and after surgery. The goal was to see if shorter surgery and this type of anesthesia might lower the ris…

This study looked at whether monitoring brain waves during general anesthesia can help predict if older adults (over 60) will experience memory or thinking problems after surgery. Researchers tracked 31 patients having elective, non-cardiac surgery and compared their brain activi…

This study looked at 50 adults having laparoscopic abdominal surgery to see if changes in the optic nerve sheath (the lining around the nerve connecting the eye to the brain) and brain oxygen levels could predict short-term memory or thinking problems after surgery. Researchers m…
