Dual-Task Training for People With Mild Cognitive Impairment and Mild Dementia

Evidence shows that people with dementia have a higher prevalence of sleep disturbance, cognitive decline, behavioral disturbance, and experience motor dysfunction. These symptoms are interrelated. However, few randomized controlled trial (RCT) studies implement dual-task training for mild cognitive impairment and mild dementia, especially for those who experience sleep problems and behavioral disturbances. Therefore, this study aims to analyze the effect of dual-task training in improving global cognitive function, executive function, working memory, sleep, behavioral disturbances, balance, and flexibility among people with mild cognitive impairment and mild dementia. The main questions it aims to answer are: 1. . Does dual-task training affect primary outcomes (global cognitive function, executive function, and working memory) 2. . Does dual-task training affect secondary outcomes (including sleep quality, behavioral disturbances, balance, and flexibility) for people with mild cognitive impairment and mild dementia?\" The length of dual-task training is 12 weeks; sessions are 3 times per week, each session lasts 45 minutes, and total sessions are 36. There are three groups of intervention (dual-task training, cognitive training, and motor training). While the control group receives the usual care. Researchers will compare the experiment and control groups to see the effect of the dual-task training.
