Investigating the effectiveness of neuro-feedback on alpha and beta frequency bands in the elderly with mild cognitive impairment

Introduction: Aging is a process in which physiological and psychological changes, especially cognitive changes, are observed. The aim of the present study was to determine the effectiveness of neuro-feedback on the alpha frequency band and beta frequency band at points (F3, F4) in the elderly with mild cognitive impairment. Methods: For this purpose, in this semi-experimental research, 30 people as an available sample from the statistical population of elderly people with mild cognitive impairment in 1400 of Tabriz city were included in the research and were placed in two control and experimental groups, the treatment plan for the experimental group included There were 15 sessions of 20 minutes of neuro-feedback and then the collected data of the experimental group and the control group from F3 and F4 areas and alpha and beta values were analyzed using multivariate covariance analysis (MANCOVA). Results: The research findings showed that neuro-feedback has a positive effect on alpha and beta frequency bands with symptoms of mild cognitive impairment (p<0.005). Considering the square of eta, it can be said that 50% of the changes caused by neuro-feedback in the alpha band were 40% of the changes caused by neuro-feedback in the beta band. Conclusion: The results of the present study showed that neuro-feedback leads to changes in alpha and beta brain waves in the elderly. Neuro-feedback can be used as a new treatment method to help brain wave changes in the elderly with mild cognitive impairment.
