Nerve block for pain may offer clues to healing the brain

NCT ID NCT06797752

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study will test whether a stellate ganglion nerve block—a procedure used for chronic pain—can improve blood flow in the tiny vessels of the eye. Researchers will use a special camera (OCTA) to scan the retinas of 50 adults before and after the block. The goal is to see if calming the sympathetic nervous system helps protect the brain after a stroke or hemorrhage.

What this could mean

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

Active substance

stellate ganglion nerve block

What this could lead to

If successful, this could reveal a new way to monitor and treat brain injuries by calming overactive nerves.

What could go wrong

This is a very small, early pilot study (50 people) that only looks at eye blood flow, not direct brain outcomes. It may not lead to any treatment change.
