The purpose of this study was to systematically review the effects of cognitive-based interventions on the cognitive function of older adults with mild cognitive impairment and conduct a meta-analysis to present basic data based on objective evidence.
This study analyzed the effects on older adults' cognitive function based on 21 studies using randomized controlled trials of cognitive-based interventions from 2000 to 2017.
The results demonstrated that the cognitive-based interventions showed statistically significant effects on language, global cognitive function, executive function, memory, visuospatial ability, and attention. All of them showed a medium effect size.
A cognitive-based intervention for older adults with mild cognitive impairment needs to be systematically and continuously applied to improve cognitive function. Such interventions can delay and prevent the progress of dementia, which will help in reducing the socioeconomic burden associated with it. In the future, it is necessary to study further, the various variables involved in continuous cognitive training programs.
