Testing brain changes after major surgery in older adults
Treatments studied
Part of Mental health clinical trials.
This study looks at how memory and thinking change after major surgery in people age 70 and older. It may help doctors understand who is at risk and how to reduce problems with thinking after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 70 or older
- You are scheduled for major surgery of the abdomen, gynecology, urinary tract, chest, or bones
- The surgery will use general anesthesia and is expected to last more than 60 minutes
- Your surgery is planned (not an emergency) and you will be seen at the pre-op clinic by internal medicine and/or anesthesia
- You can take part in thinking tests (you do not have major hearing or vision problems that stop testing)
- You can communicate in French or English

Other trials that look related to this one.
This study looks at how well older adults think and remember after surgery. It wants to see if there is a link between anesthesia, surgery, and thinking problems later on.
This trial studies whether older adults experience thinking or memory changes after major abdominal surgery. It aims to understand these changes so doctors can better support recovery.
This study tests whether using special brain monitors during and after surgery can help older adults recover better after major abdominal surgery. It looks at how these monitors might reduce confusion or other problems after an operation.
This study looks at how surgery and anesthesia affect memory and thinking in older adults who already have mild memory problems. It compares patients having elective non-cardiac surgery with a similar group who are not having surgery, to see if the surgery itself causes more confusion or memory decline.
This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.
This study looks back at information already collected around elective surgery to understand how anesthesia and surgery may affect thinking and memory (sometimes called POCD). It mainly uses records and questionnaires rather than adding a new treatment.
