Digital Health Technologies in Cognitive Rehabilitation for Cognitive Impairment: Research status and Emerging Trends

Abstract: Objective: To analyze the relevant literature on the application of digital health interventions in cognitive rehabilitation for patients with cognitive impairment, and to explore the feasibility of using digital health intervention therapies to improve the symptoms of the cognitive impairment population. Methods: Based on the research method combining bibliometric analysis and scoping review, relevant studies were retrieved from multiple English databases, with the search period ending on January 18, 2026. The included literature was then analyzed in depth. Results: A total of 556 articles were included for bibliometric analysis, and 34 articles were included for scoping review. The digital health technologies used for cognitive rehabilitation intervention mainly include computerized cognitive training, virtual reality technology (VR, MR, etc.), serious games, and mobile applications. The intervention frequency is mostly three times a week, lasting 8-12 weeks, with each session lasting 30-60 minutes. The intervention scenarios are mostly chosen to be at home or in the hospital. The feasibility of using digital health technologies to assist cognitive rehabilitation is relatively high, and patients have a good acceptance rate. To a certain extent, it has improved the cognitive function, physical function, mental health, and quality of life of elderly people with cognitive impairment. Conclusion: Overall, the application of digital health technologies in the cognitive impairment population is feasible and has a positive effect. Future research should explore multiple technical intervention methods, expand the intervention population, and further enhance the application effect of digital health technologies.
