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.
