As the aging of the population intensifies, the incidence of dementia continues to increase year by year. However, the general public's lack of awareness about dementia, combined with the complexity of the cognitive assessment process, often results in many dementia patients being diagnosed in the moderate to late stages of the disease, missing the crucial window for therapeutic intervention. This significantly affects the mental and physical health and quality of life of the elderly. With the continuous advancements in medical and information technology, the application of electronic tools in cognitive assessment is gradually increasing. This study summarizes the current application of electronic cognitive assessment tools to provide references for the development of electronic cognitive assessment tools suitable for the elderly in China.
