Brief Summary:
This randomized controlled trial is for investigating the effects of multidisciplinary intervention program on cognition and activity of daily living ability in community dwelling healthy elderly. The intervention consists of cognitive group training every month, daily home cognitive training using cognitive training smartphone application, record of weekly physical activity and body weight and feedback program, and alcohol and smoking cessation monitoring and feedback program. Among these interventions, app-based cognitive training at home is the major intervention in this study. The total duration of intervention is 1 year, and the tablet-based cognitive screening test and the patient-reported questionnaires to evaluate subjective memory decline, quality of life, depression, and activity of daily living are used for outcome measures.
