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.
Morbidity, mortality, mental health and problem behavior appears to be high in adolescence, but there is no proper intervention. This quasi-experimental study examined the effects of the neurofeedback training on the general health status, mental health and problem behavior, and the brain function quotient through structured questionnaires and brainwaves of 11 high school students (experimental group 5, control group 6). The study was conducted at I high school in Seoul from September to December, 2012. The subjects participated in the neurofeedback training twice a week for a total of 20 sessions by trained researcher. The data was analyzed using paired t-test or Wilcoxon signed rank test depending on the normality using SPSS 20.0. Significant improvement was observed in the emotion quotient and stress resistance quotient (left, right) among the brain function quotient, but not in the general health status, mental health and problem behavior.
Background:The heart continuously transmits information to the cerebrum during each pulse, and influences information processing such as perception, cognition, and emotion, which are processed in the cerebrum. This is the basis for the theory of oriental medicine widely used in psychiatric medicine and clinical practice, so-called Simjushinji (heart and brain) theory, that the heart controls the mind. The present study aims to analyze the correlation between heart and brain function by 24-hour active electrocardiogram and quantitative electroencephalogram (EEG) measurement under meditation.Methods:This randomized, controlled, assessor-blinded, 2-armed, parallel, multicenter clinical trial will analyze a total of 50 subjects, including 25 each for the test group and the active control group. Subjects will be randomly allocated to the test group (performing resource mindfulness) and the control group (performing stress mindfulness) in a 1:1 ratio. The clinical trial consists of 3 stages. The first and third stages are stable states. The second stage is divided into the test and active comparator groups. Quantitative EEG (qEEG) measurements at stages 1 and 3 will be recorded for 10 minutes; measurements at stage 2 will be recorded for 20 minutes with the eyes closed. The 24-hour Holter Monitoring and heart rate variability will be evaluated at each stage. Before the beginning of stage 3, subjects will complete the questionnaires. The primary outcome will be analyzed by independent t tests of both groups.Discussion:Scientific studies based on clinical epistemology are expected to serve as a basis for sustainable medical services in the field of psychiatric medicine in Korea. HRV, blood pressure index, and biometric index in qEEG, as determined by 24-hour Holter monitoring, will complement quantitative biomarkers and be useful in various fields.
