Magnetic pulses to the brain may lift long COVID fog
NCT ID NCT07278206
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a gentle brain stimulation technique called rTMS to see if it can reduce severe fatigue and concentration problems in people with long COVID. Researchers will give 66 adults either real or fake (placebo) stimulation over six weeks. The goal is to find a safe, non-drug treatment for these common long COVID symptoms.
