Previous studies about cognitive intervention targeting older adults revealed that cognitive
training had effects on the improvement of cognitive function.However, researches are rare
that investigated direct changes of brain structures after cognitive training.
The advanced scientific technique allowed us to develop service robots designed to assist
human work, which can be important with an increase in the aging population and high costs of
elderly care. In this regard, the investigators considered robots for elderly's cognitive
training and developed 17 cognitive programs in collaboration with Center for Intelligent
Robotics at Korea Institute of Science and Technology.
The purposes of this study were to demonstrate the effects of the investigators newly
developed robot assisted group cognitive training programs on the brain in older adults and
to identify whether they can help to improve cognitive function or mood in the elderly
compared to the conventional cognitive training or control group that were not involved in
any cognitive training.
