Development of a training program to activate brain functions of the elderly

With Japan’s rapidly aging population, cognitive decline among the elderly has become a major public health concern. This study aims to develop a brain training program using 3D tasks set in nostalgic Showa-era and modern living rooms. The program evaluates cognitive function through task performance, questionnaire responses, and brain activity measured by Near-Infrared Spectroscopy (NIRS), a low-cost, non-invasive tool that tracks changes in brain oxygen levels. By stimulating memory through familiar, nostalgic environments, the training encourages neuroplasticity, helping to maintain or improve learning and memory. A questionnaire revealed that Showa-era settings effectively triggered memory recall in older adults. Based on these findings, we designed a reminiscence-based training program and first tested it on younger participants to validate its effectiveness. This approach aims to enhance motivation and cognitive engagement, ultimately contributing to early diagnosis and prevention of cognitive decline in the elderly.
