Brain Exercising Games With Consumer-Grade Single-Channel Electroencephalogram Neurofeedback: Pre-Post Intervention...

Area of Science:

• Gerontology
• Neuroscience
• Cognitive Psychology

Background:

• The global aging population presents challenges, including increased age-related illnesses like dementia.
• Preventive care strategies are crucial for managing cognitive decline in the elderly.
• Developing accessible and scalable cognitive enhancement tools is a priority.

Purpose of the Study:

• To evaluate the efficacy of neurofeedback-based brain training games for improving cognitive performance in the elderly.
• To assess the feasibility of using low-cost, single-channel electroencephalogram (EEG) headsets for scalable cognitive training.
• To explore the potential for home-based adoption of these brain training games.

Main Methods:

• A neurofeedback system with five brain exercise games was implemented in five Thai hospitals.
• Participants underwent cognitive screening (Thai Mental State Examination, Montreal Cognitive Assessment) and detailed assessment (CANTAB, 16-channel EEG).
• Cognitive performance and EEG data were compared before and after 20 training sessions.

Main Results:

• Significant improvements were observed in visual memory (delayed matching to sample), attention (median latency), and visual recognition (spatial working memory).
• Electroencephalogram (EEG) data indicated enhanced upper alpha activity in the occipital area during a resting state, correlating with improved attention.
• Thirty-five participants completed the training, demonstrating positive outcomes.

Conclusions:

• Practical neurofeedback-based training games show potential for enhancing cognitive performance in the elderly.
• The use of low-cost EEG technology supports the scalability and accessibility of cognitive training interventions.
• These findings suggest a viable approach for home-based brain exercise to support cognitive health in aging populations.
