Attention, Memory and Quality of Life in Post-COVID-19 Adults

The participants will be submitted to a qEEG-neurofeedback intervention in order to verifify its feasibility to enhance cognition. The theta/beta ratio reduction protocol at electrodes Fp1, Fp2, Fz, F3, F4, Cz, C3, C4 will be performed, with 10 sessions of qEEG-neurofeedback training, 2 sessions for pre and post test, and 1 session for follow-up after 30 days of intervention. Each session will last approximately 1 hour. The Psychological Battery of Attention 2 (BPA-2) and Digit Span Test will be employed to measure attention and working memory levels. The Montreal Cognitive Assessment (Moca) will be used for neurological and cognitive assessment. Participants will receive feedback based on their theta/beta ratio in the frontal and central cortical areas (electrodes Fp1, Fp2, Fz, F3, F4, Cz, C3, C4).

The participant will be submitted to an inactive qEEG-neurofeedback that appears to be the same as a functional procedure or device. Participants will not receive feedback based on their theta/beta ratio in the frontal and central cortical areas (electrodes Fp1, Fp2, Fz, F3, F4, Cz, C3, C4).
