Can brain training zap long COVID brain fog?
NCT ID NCT07005921
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This study explores whether a non-invasive brain training technique called qEEG-neurofeedback can help adults with long COVID who struggle with attention, memory, and self-reflection. Participants will undergo 10 sessions of neurofeedback aimed at normalizing brain wave patterns. The trial also surveys how cognitive failures relate to quality of life and self-awareness in this group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- qEEG-neurofeedback training
- What this could lead to
- If it works, this could offer a non-invasive, drug-free way to improve attention and memory in people with long COVID brain fog.
- What could go wrong
- This is a small, early-stage trial with only 41 participants. The intervention requires multiple sessions and may not produce lasting benefits. Results may not generalize to all long COVID patients.
