Abstract: (1798 Views)
Objectives: Aphasia is a language disorder caused by damage to a specific region of the brain that regulates the expression and comprehension of language. For many years, attempts to rehabilitate aphasic patients have been made. In this study, the efficacy of low-resolution electromagnetic tomography analysis (LORETA) z-score neurofeedback (LZNFB) training for enhancing language, working memory, and attention in a group of 13 non-fluent aphasic patients was investigated.
Methods: The quantitative electroencephalography (QEEG)/LORETA and behavioral tests were administered at baseline and after 15 LZNFB treatment sessions. Using the NeuroGuide software, version 3.0.9, the LORETA analysis was conducted
Results: The LORETA metrics revealed an increased high beta at the orbital frontal, beta at the medial frontal, and Alpha at the superior frontal, as well as decreased delta and theta at the cingulate gyrus. The behavioral tests revealed improved scores for language, working memory, and attention.
Discussion: These results are extremely encouraging, as they suggest that LZNFB training could provide a range of improvements and offer new hopes to individuals with aphasia who were unable to achieve satisfactory improvements with conventional therapies.

• Low-resolution electromagnetic tomography analysis (LORETA) Z-score neurofeedback is effective in aphasia recovery.
• LORETA Z-score neurofeedback can increase fast brain waves (high beta, beta, alpha) and decrease slow brain waves (theta, delta) at specific brain regions to improve aphasia symptoms.
• LORETA Z-score neurofeedback can improve language, working memory, and attention performances.
Plain Language Summary
In this original study, we estimated the effectiveness of Low-resolution electromagnetic tomography analysis (LORETA) Z-score neurofeedback on aphasia patients. According to literature, in aphasia brain waves alter to decreased fast brain waves and increased slow brain waves. Moreover, neuromodulation represented by Neurofeedback has been reported in past studies to be useful in normalizing brain waves. Therefore, we hypothesized that Loreta Z score neurofeedback (LZNFB) can improve aphasia symptoms by normalizing brain waves. Our findings of LORETA analysis showed increased fast brain waves and decreased slow brain waves over the 15 sessions of LZNFB. Moreover, language, working memory, and attention improved after treatment. We concluded that this method is effective in aphasia rehabilitation and can be used in the treatment of aphasia.
