Summary

This pilot study tests whether a non-invasive device that gently stimulates the vagus nerve through the ear can improve letter learning in 100 adolescents with dyslexia. Participants will learn new letter-sound relationships during six 30-minute sessions while receiving either active or sham stimulation. The study also uses brain scans to see if the stimulation changes how the brain responds to letters. However, the trial is currently suspended, and the main goal is to see if the approach is feasible and tolerable.

What this could mean

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

Active substance: transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to: If it works, this could point toward a new way to help children with dyslexia learn letters more easily.
What could go wrong: This is a very early pilot study focused on feasibility, not proof of effectiveness. The trial is currently suspended, and results may not show clear benefits.
