Conclusion
Neuro-World, depression, MCI, HB-CCT failure
In this study, we introduced a home-based cognitive treatment method, namely the Neuro-World, for community-dwelling adults with MCI. We have empirically demonstrated the efficacy of HB-CCT through various evaluations, including language, memory, executive function, and depression. This study proved that HB-CCT is a useful cognitive training tool for community-dwelling adults with MCI and a helpful remote feedback tool for therapists and professionals in hospitals. We also suggested ways of reducing HB-CCT failure in older adults. As the next step of this study, a larger randomized controlled trial comparing HB-CCT with other CCT programs would be necessary.
