“…Primary variables measured included simple electroencephalography (EEG) data, specifically β (13.5–30 Hz) and α (8–13 Hz) waves, obtained using the Brain Pro FM-939 electroencephalograph (FUTEC Electronics Co., Ltd.; Yokohama, Japan). Using a simple EEG, two FUTEK Sensor Pro SEN-PRO sensors are attached symmetrically to the left and right sides of the parietal region’s midline with conductive paste and measured for three minutes [ 15 ]. Brain waves are recorded to assess the state of relaxation.…”

This study examines the impact of reminiscence therapy on cognitive and emotional well-being in institutionalized older patients with dementia. Conducted at the Long-Term Care Health Facility for the Elderly, the research involved 34 participants who underwent therapy sessions that included personalized discussions of past experiences. Using physiological markers such as electroencephalography alpha and beta waves, along with psychological measures such as the Hasegawa Dementia Scale—Revised, the study aimed to quantify the effects of the therapy. Although the results indicated positive correlations between alpha and beta waves, suggesting enhanced relaxation and cognitive engagement, improvements in Hasegawa Dementia Scale—Revised scores were not statistically significant, pointing to variability in therapeutic effectiveness among patients. Despite these mixed outcomes, the findings support the potential of reminiscence therapy as a non-pharmacological intervention to improve the quality of life of dementia patients, though they also underscore the necessity for further research to refine therapy protocols and enhance applicability.

Purpose: Dental treatment is a stressful event. The aim of this study was to evaluate the feasibility of electroencephalography (EEG) for the measurement of stress the stress of the patient's ongoing dental treatment. Materials and Methods: Real-time brain activity was measured for five healthy subjects (three males and two females) under contentious opening mouth conditions and compared with the relaxed conditions for 18 minutes. Brain activities were measured under the conditions that subjects were sited on the dental chair in horizontal situation. Electroencephalograph (EEG) were used to measure the five type of brain waves: θ, α 1 , α 2 , α 3 , and β. Results: In θ wave, α 3 wave and β wave, widening gap between opening mouth condition and closing mouth conditions were observed with over the time course. This tendency was confirmed by autoregressive moving average (ARMA) model and mixed effect modeling. All of the coefficients of opening mouths were statistically significant, when closing mouth used as reference. EEG may be useful tool to measure the stress during dental treatment. Stress by sitting on dental chair in horizontal situation was depended on personality traits. Conclusion: Contentious opening mouth may be stressful; however, the amount of stress may be small. The changes can be seen within 18 min. Prolonged chair time for the dental treatment may not be recommended.

“…The brain waves were measured using a BrainPro FM-929 (Futek Electronics Co., Ltd. Yokohama, Japan), and the HRV was measured by a TAS9VIEW (YKC Corporation, Tokyo, Japan) for 30 min. Electroencephalography is a medical imaging technique used to reflect brain state or activity [18]. HRV reflects the function of the autonomic nervous system (ANS) as heart rates are regulated by the ANS.…”

The relationship between adverse health effects, including sensory irritation and decline in cognitive performance, and the exposure to indoor air pollutants has been considered inconclusive. This is possibly because the occurrence of relevant symptoms seems to largely depend on individual sensitivity and mental state. Therefore, further evaluation of the relationship between indoor environment and its related adverse health effects using subjective and objective data is required. In 2017, two new laboratory houses (LHs) were built on the campus of Chiba University (Japan) as part of a new project called the Chemiless Town Project, phase 3. This project aims to investigate the impact of the indoor environment on physical and mental health and to construct a healthy indoor environment. The interior and exterior appearances of the two LHs appear the same; however, the concentrations of chemicals inside them differ due to the differences in their construction and interior materials. The project commenced in November 2017 and will continue until 2021. In the project, approximately 400 participants will be recruited who will evaluate indoor air using sensory perception. The evaluation will be performed using objective methods, including monitoring brain waves and heart rate variability, and subjective methods, including completing self-reported questionnaires, while staying in each LH. Simultaneously, the indoor air samples of each laboratory will be collected and analysed. In 2017, 17 healthy female and 26 healthy male volunteers participated in the experiment. The median of sum concentrations of volatile organic compounds in the indoor air of each LH were 314 and 1674 μg/m 3 , respectively. No significant differences were found in terms of degrees of performance and relaxation of participants between the LHs. Additional research and analysis will be conducted with more participants to further examine the relationship between the indoor environment and related health effects.
