New research from the Perelman School of Medicine adds to the growing evidence that anesthesia and surgery may be associated with the progression of chronic brain diseases, particularly Alzheimer’s disease. “We have long sought a clearer picture of the true impact of anesthesia and surgery on the central nervous system,” study author Roderic Eckenhoff, MD, the Austin Lamont Professor of Anesthesia, said in a HealthDay article. “Although not definitive, this human biomarker study gives some credibility to the notion that anesthesia and surgery produce an inflammatory insult on the brain and accelerate chronic neurodegenerative diseases like Alzheimer’s,” Eckenhoff added.
