Mild cognitive impairment (MCI) may increase the risk of dementia. This study will evaluate an 8-week community-family mutual support intervention for adults aged 60 years or older with MCI. Participants will be randomly assigned to an intervention group or a control group. The control group will receive routine community care, while the intervention group will additionally receive cognitive training, health education, family support, mutual support activities, and individualized feedback. Cognitive function, daily functioning, emotional status, and social support will be assessed before and after the intervention.
