New brain monitoring tech could predict stroke after brain bleed
NCT ID NCT07577739
First seen May 15, 2026 · Last updated Jun 22, 2026 · Updated 7 times
Summary
This study looks at 300 adults with a type of brain bleed called aneurysmal subarachnoid hemorrhage. Researchers want to see if a non-invasive headband can accurately monitor brain pressure and blood flow, replacing the need for invasive probes. They will also test two nerve stimulation techniques—a neck injection and a mild ear nerve stimulator—to see if they improve brain blood flow regulation. The goal is to find better ways to prevent delayed brain injury and improve recovery.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ropivacaine (for cervical sympathetic block) and transcutaneous auricular vagal nerve stimulation (taVNS)
What this could lead to
If successful, this could lead to better, non-invasive ways to monitor brain health after a brain bleed and help prevent delayed complications like stroke.
What could go wrong
This is an early-stage study focused on validating monitoring tools and exploring nerve stimulation effects. It is not designed to prove a treatment works, and the nerve stimulation procedures carry risks like temporary Horner syndrome or discomfort.
