1. Brain training and evaluation_In terms of brain training, as the effectiveness of the dual-task method where the subject calculates while walking, have not been widely reported in the prior research, we combined dual-task and learning therapy. This evaluation used the MCI screening "MoCA test". 2. Aerobic instruction and evaluation_This is a concept showing a correlation between a reduction in walking speed and cognitive function. In order to prevent Motoric Cognitive Risk syndrome, they were instructed to walk at a fast speed for 20 minutes or more, three times a week, and increase their usual stride by 5 centimeters._This evaluation uses the "2 step test", in which walking function is evaluated from size of stride. 3. Emotional evaluation and relationship between cognition and emotion: Most of non-drug treatments for cognitive functions of elderly are methods to promote pleasant mood, such as music therapy and horticultural therapy. Until now, emotional effects based on memory have been reported, yet, it is not clear how much emotion has effects on memory. Therefore, I evaluated emotion of subjects and further analyzed the relationship between emotion and cognition.
