NCT ID NCT07154199
First seen Jun 26, 2026 · Last updated Jun 26, 2026
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.
