Headband could spot deadly brain vessel spasms before they strike

NCT ID NCT04042571

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a non-invasive device placed on the forehead (NIRS) can detect blood vessel spasms in the brain after a severe aneurysm rupture. Fifty patients were monitored continuously from day 4 to day 12 after their bleed. The goal was to see if this oxygen-measuring device could spot spasms earlier than standard tools like ultrasound or CT scans.

What this could mean

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

Active substance

Near-infrared spectroscopy (NIRS) monitoring device

What this could lead to

If successful, this could lead to earlier detection of vasospasm after brain hemorrhage, potentially preventing strokes and improving recovery.

What could go wrong

This is a small, early-stage study with only 50 participants. The device may not prove more accurate than current methods, and results may not apply to all patients.
