Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study looks at why some older adults experience delirium, a state of confusion, after brain tumor surgery. Researchers will monitor blood pressure and brain wave activity during surgery in 164 patients to see if these factors are linked to postoperative delirium. The goal is to understand the mechanisms behind this condition and find ways to prevent it.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Intraoperative monitoring of blood pressure and electroencephalogram (EEG) during brain tumor surgery
What this could lead to
If it works, this could lead to better ways to prevent and treat postoperative delirium in older adults after brain surgery, potentially reducing hospital stays and improving recovery.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The findings may not apply to all patients, and the monitoring techniques may not fully capture the complex causes of delirium.
