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

Condition(s) studied

Investigational drug(s) / intervention(s)

Multi-domain Cognitive Intervention: * Cognitive rehabilitation includes home-based exercise, three times per week, for 30 minutes each session. * Cognitive stimulation involves art therapy, once a week, for 90 minutes per session. * Cognitive training encompasses memory, attention, executive function, and visuospatial training, conducted three times per week, with each session lasting 30 minutes. * Health education, once a week, covering the prevention and treatment of chronic diseases in the elderly, as well as healthy lifestyles for the elderly.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Global cognitive function — Baseline (pre-intervention), six-month follow-up (post-intervention)
  The Chinese version of Montreal Cognitive Assessment will be used to assess the global cognitive function.The scale has a total score of 30 points, encompassing eight assessment sections: visual-spatial and executive function, naming, memory, attention, language, abstraction, delayed recall, and orientation. It involves multiple cognitive domains. A higher score indicates better cognitive functioning.
