Effects of Cognicise-Neurofeedback on Health Locus of Control, Depression, and Quantitative Electroencephalography Alpha Asymmetry in Elderly Women

Abstract

Background: With an increase in the aged population, there is a growing concern regarding the care of the elderly. This study aims to identify effects of cognicise-neurofeedback on health locus of control, depression, and quantitative electroencephalography (QEEG) alpha asymmetry in elderly women. Methods: A quasi-experimental control group pre-test–post-test design was used. Korean women aged 65 years or over at a senior welfare center were randomly allocated to the control (n = 12) or experimental (n = 19) groups from July to October 2019. The intervention consisted of cognicise (exercise with intensified cognitive activity) and neurofeedback twice a week for 10 weeks. The locus of control and depression were measured via self-reported questionnaires. QEEG alpha asymmetry was measured using BrainMaster. Results: Depression significantly decreased in the experimental group (t = 4.113, p = 0.001), while internality in the locus of control significantly decreased in the control group (t = 3.023, p = 0.012). On the other hand, QEEG alpha asymmetry index differences in F3-F4 between the pre-test and post-test were not significant in the experimental group (t = 0.491, p = 0.629) or control group (t = 0.413, p = 0.678). Conclusions: Due to the coronavirus disease (COVID-19) pandemic, contact between the elderly and healthcare workers in the clinical practice field has become more restricted. These findings can help decrease negative emotions among elderly women in the community based on an integrated neuroscientific approach.

Probing fMRI brain connectivity and activity changes during emotion regulation by EEG neurofeedback

“…Several applications of EEG frontal asymmetry are listed in Coan and Allen (2004). As mentioned in several previous studies (Coan and Allen, 2004;Peeters et al, 2014a;Allen and Reznik, 2015;Mennella et al, 2017;Allen et al, 2018;Meyer et al, 2018;Xu et al, 2018;López-Castro et al, 2021;Trambaiolli et al, 2021;Weon et al, 2021), EEG frontal asymmetry can be used as an indication of different emotional states and a biomarker for PTSD, anxiety, and depression.…”

“…Therefore, QEEG can also be used in diagnosing and treating patients who develop neurological disorders due to SARS-CoV-2 virus infection (Pastor et al, 2020;Campanella et al, 2021). Information obtained from QEEG can provide the basis for functional assessment of the brain, diagnose disorders, and differentiate their effects (Weon et al, 2021). It is necessary to choose the most individualized therapeutic protocol corresponding to the patient's current state to detect disorders (Kesebir and Yosmaoglu, 2018;Kopańska et al, 2021).…”
