Impact of the Digital Multi-domain Cognitive Intervention in High-risk Populations for Dementia

Impact of the Digital Multi-domain Cognitive Intervention in High-risk Populations for Dementia

Dementia is a chronic, progressive neurodegenerative disease characterized by acquired cognitive impairment as its core manifestation. The most common type of dementia is Alzheimer's Disease (AD), also known as "Senile Dementia," accounting for 60-80% of all dementia cases. Currently, there are approximately 10 million AD patients in China, with the number showing an increasing trend year by year, imposing a heavy economic and caregiving burden on families and society. Studies have shown that AD has a clinically silent period of 15 to 20 years (SCD\MCI), where the risk of developing dementia is ten times higher than that of healthy elderly individuals. Nearly 50% of MCI patients progress to dementia within 5 years, and about 14.1% of SCD patients develop dementia within the same timeframe. Early detection, diagnosis, and intervention are currently the most effective strategies for preventing and treating AD. Therefore, this study aims to verify the intervention effect of integrated cognitive intervention in high-risk populations for senile dementia (SCD, MCI) based on the cognitive rehabilitation model through randomized controlled trials, and to analyze attrition rates, participation rates, etc., which have good research and application value.

Based on the cognitive rehabilitation model, this study aims to develop a digital multimodal cognitive intervention program, and conduct feasibility studies and randomized controlled trials. The intervention includes health knowledge education, exercise intervention, art intervention, and cognitive training, etc. The feasibility, effectiveness, and safety of this intervention approach will be evaluated.
