Post Surgery Brain Fog: New Evidence Questions Long-Term Safety of Anesthesia

Post Surgery Brain Fog: New Evidence Questions Long-Term Safety of Anesthesia Introduction Post-surgicalbrain fog represents a significant and under-recognized complication of anesthesia and surgery, affecting a substantial proportion of patients. Perioperative neurocognitive disorders (PND), which encompass postoperative delirium and longer-term cognitive decline, are reported in 11.7% to 63% of individuals following surgical procedures under general anesthesia. This wide range reflects both differences in study methodology and the heterogeneous nature of patient populations, but it underscores the fact that cognitive complications are far from rare. Importantly, these deficits can extend well beyond the immediate postoperative recovery period and may persist
