Smell therapy to prevent confusion after surgery
Part of Brain & nervous system clinical trials.
This study tests whether a simple smell-based activity before and after surgery can help prevent confusion and memory problems in older adults. It is for people 65 and older who are having a long surgery under general anesthesia.

This trial tests if a brain-training technique called neurofeedback can help older adults avoid confusion or memory problems after major surgery. It's for people 65 or older having planned abdominal or chest surgeries under general anesthesia.
This study looks at older patients (65 and older) who have had surgery and anesthesia. It aims to find who is at risk for confusion (delirium) and memory problems afterward. The goal is to help doctors prevent these issues.
This study tests whether smelling certain oils can help prevent confusion (delirium) in older adults who have had surgery for a broken bone and are in the intensive care unit. It is only for adults age 60 and older who can speak Turkish and do not have breathing problems or memory issues.
This study tests if a special thinking exercise before and after surgery can help prevent confusion (delirium) in older adults. It is for people 65+ having certain long surgeries with general anesthesia.
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 tests whether avoiding opioid pain medicines during anesthesia can help prevent confusion after surgery in older adults having stomach or bowel surgery. You would receive opioid-free anesthesia instead of standard opioids.
