Abstract Virtual reality technology can intuitively provide patients of neuropsychological diseases with an almost real environment for cognitive rehabilitation training . In this paper, virtual reality technology is used to construct specific scenes that are universal and related to MCI patients to restore and train patients’ scene memory cognitive ability to help patients strengthen or gradually restore scene memory cognitive ability. The construction of virtual reality scenes with different contents such as life, environment, transportation and tourism, real-time detection is carried out in combination with EEG signals of patients in different scenes. The experimental results of the analysis of EEG signals of patients shows that memory rehabilitation training is strengthened by using specific stimulation scenes. Keywords: MCI, Rehabilitation training, VR, EEG Introduction At present, VR has been proposed to treat some neuropsychological diseases, such as anxiety and fear. Virtual reality technology can intuitively provide patients with an almost real environment, so that patients can be placed in the middle, and get better treatment effect. In this regard, we have carried out some research before [1–4]. At the same time, VR can also be used in surgical training, providing a recyclable and ecologically efficient way for physicians to gain more training experience. VR can also be used for other medical purposes such as poststroke intervention and treatment. Carlos et al. Proposed a novel P300 Brain-Computer Interface (BCI) paradigm based on VR technology [5] , which uses soc7izial clues to guide the focus of attention and combines VR technology with the characteristics of P300 signals into a training tool, which can be used to train social attention disorders. Alexander optimizes the current BCI [6, 7]; Ioannis et al. Proposed a computer intervention based on virtual reality, which can be used for cognitive stimulation and can evaluate the condition *Correspondence: [email protected] 2 Cyberspace Institute of Advanced Technology, Guangzhou University, Guangzhou 510006, China Full list of author information is available at the end of the article © Springer Nature Switzerland AG 2020.
of cognitive diseases such as MCI [8]. Dong Wen et al. Proposed a research on evaluation and rehabilitation of cognitive impairment at different stages based on virtual reality and EEG [9]. Yang and Tan et al. Pointed out that although some achievements have been made in VRbased EAR for MCI and AD patients, VR-based EAR for SCD patients has not yet begun. SCD patients are preclinical states of MCI and AD, and the evaluation of SCD patients is mainly limited to cerebrospinal fluid and EEG methods [10, 11]. Innes proposed that SCD rehabilitation is limited to meditation, music therapy [12], and mindf
