Effects and Mechanism of the Fully Immersive Virtual Reality Cognitive Training Based on Leisure Activities

The aim of this study is to identify the effects of the immersive leisure-based VR cognitive training, and compare the intervention effects for elderly with MCI and SCD. The investigators anticipate the VR training can facilitate cognitive function, daily function, quality of life. The investigators anticipated the metabolic biomarkers, mechanism, and brain activities will be found. The significance of this study is identifying the effect of immersive leisure-based VR cognitive training, and confirming the metabolic biomarkers and brain activities. It could improve the accuracy of identification, prevent the progression to dementia, and lead the field of technological assistance to new opportunities for training.
