VR训练对轻度认知障碍老年人认知功能的影响及神经机制

Elderly people with mild cognitive impairment (MCI) is a high-risk group for dementia. However, their brains retain structural and functional plasticity. Virtual reality (VR) based training can help delay the progression of MCI towards dementia. VR training can improve the overall cognitive function, especially memory, attention, and executive function?of MCI elderly people.?The intervention effect is influenced by factors such as immersion level, training form, and task content. VR training improves the efficiency of neural activity in elderly MCI patients, which is manifested by changes in the activation level of relevant brain regions and an increase connectivity between brain regions. VR training is expected to become a supplementary method for cognitive improvement in elderly MCI patients. Future research should clarify the dose-effect relationship of VR intervention, focus on its long-term effects, and further explore the potential mechanisms of VR training to improve cognitive function in elderly MCI patients.
