This study included 136 patients, so it is a small study. The patients being examined were older and about to undergo knee or hip replacement surgery.
Some of the patients did perform worse on cognitive test after their operation. The current hypothesis is that more Abeta is being accumulated in the brain.

New Study Finds Key Proteins of Alzheimer’s In The Cerebrospinal Fluid of Older Patients Post Surgery
New research examining levels of the hallmark proteins linked to Alzheimer’s disease found in patients suffering from post-operative cognitive changes (POCC) may lead to safer surgery care and better post-operative outcomes for senior adults.
“With these results, we can continue to work toward improving our surgery care and outcomes for these senior adults,” said Xie. “This is an important finding as we continue to learn about the long-term effects of anesthesia and surgery can have on senior adults and their post-operative thinking.”About Cure Alzheimer’s Fund
