Improvements in Cognition and Promoting Relaxation: A Preliminary Study of Immersive Virtual Reality for Institutionalized Elderly

This study investigates the effects of immersive virtual reality (VR) on cognitive function and well-being in elderly individuals residing in institutional settings. Based on cognitive rehabilitation theory and multisensory stimulation, 33 participants were randomly assigned to either a VR intervention group or a control group. The intervention group experienced VR environments (beach, field, city), while the control group maintained their institutional routine activities. Cognitive function was assessed using the MoCA, RAVLT, PBA, and Digit Span tests. Emotional health was assessed using the GDS-30 and SF-36. Physiological measures included blood pressure, oxygen saturation, and heart rate. Results showed significant cognitive improvements, especially in attention, memory recall, and learning, in the VR group. Emotional health remained stable, while the reduction in heart rate indicated a relaxation response associated with VR immersion. This study highlights VR as a promising, non-invasive tool for cognitive enhancement in elderly care. Given global aging trends and cognitive decline, these findings may have potential for broader application in institutional settings.
