Effects of the Fully Immersive VR Cognitive Training Based on Leisure Activities for the Elderly With MCI and SCD.

Mild cognitive impairment (MCI) and subjective cognitive decline (SCD) are risk groups for dementia, and thus appropriate interventions are required. Cognitive training is a common intervention applied to the elderly with cognitive decline. Cognitive training integrated into leisure activities can increase the training motivation of the elderly, while improving cognitive performance and daily functions. Virtual reality (VR) can simulate daily living situations, and it can be an effective intervention with cognitive training. Although a few studies have found immersive VR cognitive training can improve the cognitive function of the elderly with cognitive decline, these studies have shown inconsistent results. In addition, it is yet not clear the long-term effect of fully immersive VR cognitive training and its impact on daily function. Furthermore, for immersive VR cognitive training, there is still a lack of training programs that integrate into the context of leisure activities. This type of VR cognitive training could help the effectiveness of cognitive training to be transferred into daily functions.
