Memory training by Chinese Classics recitation: At least five minutes memory training per day, for six months
Study summary
Subjective cognitive decline (SCD) is considered a preclinical condition associated with an increased risk of dementia and Alzheimer's disease. Effective early behavioral interventions remain limited, and the neurobiological mechanisms underlying cognitive training effects are not fully understood, particularly in culturally specific educational contexts.
This randomized, assessor-blinded, controlled clinical trial will enroll 60 individuals with SCD to evaluate the effects of a six-month structured Chinese Classics recitation training program. Participants will be randomly assigned to either an intervention group or a non-active control group. Assessments will be conducted at baseline, immediately post-intervention, and during annual follow-up.
Multimodal evaluations will include neuropsychological testing, functional magnetic resonance imaging (fMRI), electroencephalography (EEG), blood biomarker profiling, gut microbiota analysis, and fecal metabolomics. The study aims to examine clinical outcomes and explore potential neurobiological and systemic correlates associated with culturally adapted cognitive training.

Primary outcome measure(s)
Change in task-related brain activation measured by functional MRI — Baseline and 6 months Unit of measure:
Whole-brain blood-oxygen-level-dependent (BOLD) signal change (%)
Detail Functional magnetic resonance imaging (fMRI) will be used to evaluate changes in task-related brain activation associated with the intervention. Whole-brain blood-oxygen-level-dependent (BOLD) signals will be analyzed using voxel-wise general linear modeling to identify activation patterns during task performance compared with resting baseline. First-level analyses will generate subject-specific contrast maps reflecting task-related neural activation. Group-level random-effects analyses will then be conducted to compare activation patterns between study groups and across time points. Statistical significance will be determined using a voxel-level threshold corrected for multiple comparisons using the false discovery rate (FDR). Effect sizes extracted from significant brain regions will be used for group-level comparisons.
