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.
