详细说明
With the rapid aging of the global population, mild cognitive impairment (MCI) has become a critical stage for dementia prevention and early intervention. Cognitive training is recognized as one of the most effective non-pharmacological interventions for individuals with MCI. Among various approaches, adaptive computerized cognitive training (CCT) can dynamically adjust task difficulty according to an individual's performance, thereby improving training personalization, engagement, and adherence. However, evidence regarding the optimal maintenance training frequency and the long-term sustainability of cognitive benefits remains limited.
This study adopts a quasi-experimental design and will recruit community-dwelling adults aged 60 years and older with MCI from three communities in Shenyang, Liaoning Province, China. All participants will complete a 12-week adaptive computerized cognitive training program using the Heling Brain Planet WeChat mini-program, with training sessions lasting 30 minutes, three times per week. After the initial intervention, participants will be assigned to either a high-frequency maintenance training group, which will continue training three times per week, or a training discontinuation group, which will receive routine community health management only. Follow-up cognitive assessments will be conducted after the intervention and during the follow-up period.
The primary outcome will be global cognitive function assessed by the Montreal Cognitive Assessment (MoCA). Secondary outcomes will include memory (Auditory Verbal Learning Test, AVLT), attention (Trail Making Test Part A, TMT-A), executive function (Stroop Color-Word Test), language (Boston Naming Test, BNT), visuospatial ability (Clock Drawing Test, CDT), and activities of daily living (ADL). The effects of different maintenance training frequencies on cognitive improvement and the persistence of intervention benefits will be compared.
This study is expected to evaluate the effectiveness of adaptive computerized cognitive training for improving cognitive function in community-dwelling older adults with MCI and to determine whether continued maintenance training can prolong cognitive benefits. The findings will provide evidence for optimizing community-based digital cognitive training programs and developing sustainable intervention strategies for the long-term management of older adults with MCI.

实验性的：High-Frequency Maintenance Training
Participants will receive adaptive computerized cognitive training using the Heling Brain Planet WeChat mini-program.
During the initial intervention phase, participants will complete training sessions three times per week for 30 minutes per session over 12 weeks.
After the initial intervention, participants will continue maintenance training three times per week until the end of the follow-up period.
The training program automatically adjusts task difficulty according to individual performance and includes exercises targeting attention, memory, executive function, language, visuospatial ability, and other cognitive domains.

Participants receive adaptive computerized cognitive training delivered through the Heling Brain Planet WeChat mini- program.
The intervention consists of individualized cognitive exercises targeting multiple cognitive domains, including attention, memory, executive function, language, visuospatial ability, perceptual-motor function, and social cognition.
The training difficulty is automatically adjusted according to each participant's performance to provide personalized cognitive stimulation.
During the initial intervention phase, all participants complete 30-minute training sessions three times per week for 3 months.
After the initial intervention, participants choose to continue training receive maintenance adaptive computerized cognitive training.
