- Interventions
- Other: group cognitive interventionOther: Home-based cognitive intervention
- Registration Number
- NCT01358955

- Inha University Hospital
- Brief Summary
* There will be a significant difference in cognitive function between cognitive intervention group (group therapy) and a wait list control group.
* There will be a significant difference in cognitive function between a home-based cognitive intervention group and a wait list control group.
- Detailed Description
The change of Modified ADAS-cog score from the baseline to post-intervention will be compared between the cognitive intervention group and wait list control group.
