Dementia is a clinical syndrome caused by pathological changes in the brain. It is primarily characterized by cognitive decline, behavioral disturbances, and personality changes, all of which severely impair patients’ quality of life. As global populations age and the prevalence of dementia rises, the demand for long-term care has intensified. This situation places a significant physical and psychological burden on families and creates substantial socioeconomic pressure, establishing dementia as an urgent public health priority. In response, video games have emerged as a valuable non-pharmacological tool in dementia health management. Recognized for their low cost and non-invasiveness, they demonstrate considerable potential in improving cognitive function, early screening, alleviating behavioral symptoms, and health education.  This article systematically reviews the existing evidence for video games in dementia health management, examines challenges such as clinical standardization, senior adaptability, and technology integration, and proposes future directions. These include establishing standardized frameworks, optimizing game design, and expanding application scenarios. The aim is to provide a reference for integrating video games into the holistic and standardized management of dementia.
