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.
