Brain fog after surgery in older adults: a sleep study
Part of Mental health clinical trials.
This study looks at why some older adults have trouble thinking clearly after surgery. It tests if sleep problems and a natural chemical called melanin concentrating hormone are linked to this brain fog.
Summary written for real people, not researchers, by Clin2.

- You are 65 years or older.

Other trials that look related to this one.
This study looks at how older adults' thinking and memory may change after a common prostate surgery, and whether some patients become confused or delirious afterward. It may help doctors understand who is at risk for these problems.
This study measures whether women experience changes in thinking and memory after having gynecologic surgery (removal of uterus and/or ovaries). Researchers want to understand how anesthesia and surgery affect the brain and identify who might be at risk.
This trial looks at how well the brain controls its own blood flow during non-cardiac surgeries. It aims to see if problems with this regulation are linked to confusion after surgery (delirium).
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 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 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.
