- Conditions
- Mild Cognitive Impairment (MCI)
- Registration Number
- NCT06942780
- Lead Sponsor
- Xuanwu Hospital, Beijing
- Brief Summary
This clinical study aims to evaluate the feasibility and preliminary effectiveness of a comprehensive lifestyle intervention program for patients with mild cognitive impairment. The intervention consists of four components: cognitive training, physical exercise, MIND diet, and group social activities.
The hypothesis is that this integrated healthy lifestyle intervention may slow cognitive decline, improve daily functional abilities, and enhance the quality of life in MCI patients. Feasibility will be assessed based on participation rates, program completion rates, and participant satisfaction. Effectiveness will be evaluated using scales such as MoCA, MMSE.
The study participants will be clinically diagnosed mild cognitive impairment patients. If feasibility is confirmed, the results will provide a basis for larger-scale clinical trials and offer insights into non-pharmacological intervention strategies for brain health in high-risk populations.
- Detailed Description
Research Background
1. MCI Status and Impact Mild Cognitive Impairment (MCI) is an intermediate state between normal aging and dementia, characterized by cognitive decline. Globally, the prevalence of MCI among individuals aged 65 and older is approximately 15%-20%, while in China, the prevalence among those aged 60 and older is 15.5%, affecting approximately 38.77 million people.
MCI patients experience cognitive decline, reduced quality of life, and increased economic burden on families (approximately 20%-30% higher than healthy elderly individuals). The prevalence of depressive symptoms in MCI patients is significantly higher than in healthy elderly individuals.
MCI patients have a high risk of progressing to dementia, with an annual conversion rate of 10%-15%, and up to 50% progressing within five years. However, early intervention can reverse or delay the progression to dementia.
2. Importance of Healthy Lifestyle Interventions. A healthy lifestyle, including observable behaviors (e.g., diet, exercise) and indirect behaviors (e.g., psychological state, cognitive ability), plays a significant role in preventing and intervening in MCI.
Exercise Intervention: Regular exercise (e.g., brisk walking, resistance training, Tai Chi) improves cognitive function. It is recommended that older adults with cognitive decline engage in 150-300 minutes of moderate-intensity activity per week.
Social Intervention: Active social participation (e.g., interest groups, health education) reduces the risk of cognitive decline. It is recommended that MCI patients participate in social activities at least twice a week.
Dietary Intervention: The MIND diet (a combination of the Mediterranean and DASH diets) emphasizes antioxidant and anti-inflammatory foods, reducing MCI risk and slowing age-related cognitive decline.
Cognitive Intervention: Cognitive training (e.g., digital cognitive therapy) is effective in improving intervention outcomes. It is recommended that MCI patients undergo at least 3 sessions per week, each lasting 30 minutes, with a total training time of no less than 20 hours.
3. Research Status and Significance Current research on healthy lifestyle interventions for MCI patients is limited, with most studies focusing on single interventions rather than comprehensive approaches.
This study combines exercise, social activities, diet, and cognitive training to systematically evaluate the comprehensive effects of multidimensional healthy lifestyle interventions. The findings will provide evidence for developing personalized and precise intervention strategies, helping to reduce the risk of dementia conversion, alleviate family and societal burdens, and promote healthy aging.
Statistical Methods The SPSS 23.0 statistical software was used to build the database and conduct statistical analyses. Descriptive statistics were applied to describe the basic characteristics of the study subjects and the outcome indicators of the feasibility analysis. For measurement data, the Shapiro-Wilk test was used to test for normality. Normally distributed data were described using means and standard deviations, while non-normally distributed data were described using medians and interquartile ranges. Categorical data were described using frequencies and percentages.
For the outcome indicators of the effectiveness validation of the study subjects, between-group differences were analyzed. Normally distributed data were analyzed using the independent samples t-test, while non-normally distributed data were analyzed using the Mann-Whitney U test. A two-tailed p-value ≤0.05 was considered statistically significant.
Innovations
1. Perspective Innovation Starting from an overall healthy lifestyle and focusing on MCI patients, this study integrates multi-factorial interventions (exercise, diet, social interaction, and cognitive training), breaking the limitations of traditional single-factor research. Meanwhile, the intervention effects are evaluated from multiple dimensions to comprehensively measure the impact of lifestyle interventions on MCI patients.
2. Methodological Innovation Combining multi-modal interventions (cognitive training, exercise, MIND diet, group social activities) with digital technology (cognitive digital therapy, fitness trackers for heart rate monitoring), this study enables real-time multi-dimensional monitoring and data collection, enhancing intervention compliance and engagement.
3. Application Innovation Focusing on modifiable factors in the lives of MCI patients, this study designs practical interventions that can be implemented in both family and community settings. Based on the research findings, an integrated promotion model of "hospital-community-family" can be established to effectively improve the accessibility and sustainability of the interventions.
4. Research Framework Innovation This study constructs a comprehensive intervention framework that integrates diet, exercise, cognition, and social interaction, providing a reference for future research.

Name Time Method Participation rate Baseline Recruitment success rate : number of people who agree to participate/total number of people eligible and invited
Study Measures Completion 4 weeks and 8weeks Number of participants with full protocol compliance, including: attending interventions as scheduled, verifying target exercise intensity via fitness trackers, and recording MIND diet adherence in the WeChat group.
Montreal Cognitive Assessment Baseline and 8 weeks Seven sub-dimensions, including visuospatial/executive function, naming, attention, language, abstract ability, delayed recall and orientation, were scored out of 30, with higher scores indicating better cognitive ability. The sensitivity and specificity of the Beijing version of MoCA scale were 0.92, 0.84, 0.86, and 0.82 Cronbach'sa coefficient of internal consistency.
Mini-Mental State Examination Baseline and 8 weeks The scale includes the assessment of orientation, attention and computing ability, immediate recall, delayed recall, language function and visuospatial ability. The total score is 30 points, the higher the score is, the better the cognitive function, \>27 is normal, \<27 is cognitive dysfunction. The Chinese MMSE retest reliability is 0.90.
- Secondary Outcome Measures
Name Time Method 12-item Short-Form Health Survey Baseline and 8 weeks The total score of the scale ranges from 12 to 65 points. The higher the scale score, the better the quality of life. When the 12-item Short-Form Health Survey was applied to the elderly population in China, the Cronbach'sa coefficient of the scale was 0.775, indicating good reliability and validity.
Social Support Rating Scale Baseline and 8 weeks The scale consisted of 10 items and 3 dimensions (subjective support, objective support and utilization of social support), with a total score of 12 to 66 points, and the higher the score, the better the social support. The retest reliability of the scale was 0.92, and the prediction validity was good.
Geriatric Depression Scale Baseline and 8 weeks Geriatric Depression Scale is adapted by Sheikh and other scholars on the basis of the standard edition, with a total of 15 items, each item is 1 point. The scale scores range from 0 to 15 points. The higher the score, the more likely it is to have depressive symptoms. The Chinese version of GDS-15 scale has good applicability in the elderly population in China, with a one-week retest reliability of 0.728 and a Cronbach'sa coefficient of 0.793.
General information questionnaire Baseline demographic information (age, sex, education, marital status, etc.), health status (medical history, drug use, smoking and alcohol use), lifestyle (physical activity, eating habits, social activities).
Satisfaction Questionnaire 8weeks The satisfaction questionnaire covers four aspects (cognitive training, exercise, MIND diet and social activities), and gives the scores of acceptability (interest/difficulty), time commitment and overall satisfaction (5-point Likert scale), with a total score ranging from 13 to 65 points. The higher the score is, the more satisfied one will be. Open-ended questions will collect suggestions for improvement.
