First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
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 activity to cognitive changes three months later. The goal is to find early warning signs of postoperative cognitive dysfunction.
