Summary

This study tests whether a 60-second ultrasound pulse to the brain can improve thinking and memory in people with long COVID brain fog. Forty participants will receive either real or fake (sham) stimulation, and their cognitive performance will be measured before and after. The goal is to see if this safe, non-invasive technique can help clear the mental fog that lingers after COVID-19.

What this could mean

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

Active substance: transcranial ultrasound stimulation
What this could lead to: If it works, this could point toward a safe, non-invasive way to ease brain fog after COVID-19.
What could go wrong: This is a very early, small study (40 people) testing only a single 60-second stimulation. The results may not apply to everyone, and the effect may be small or temporary.
