Overview
Brief Summary
The present study aims to investigate the effects of combined physical-cognitive training on cognitive function as well as peripheral BDNF level and mitochondrial function of individuals with MCI. It is hypothesized that: 1) the combined physical-cognitive training program will be superior to the physical and cognitive training program alone; and 2) the degree of cognitive improvement will be positively correlated with the improvement of plasma BDNF and mitochondrial function.
Detailed Description
Recent research suggests that the benefits of combined physical-cognitive training may be greater than either physical or cognitive training alone. Nevertheless, this synergistic effect has been demonstrated mainly in cognitively intact older adults. Studies examining the effects of combined physical-cognitive training in older adults with MCI are scarce and show mixed results. Moreover, few studies have determined the effects of the combined training on peripheral brain-derived neurotrophic factor (BDNF) and mitochondrial function. Thus, the present study aims to investigate the effects of combined physical-cognitive training on cognitive function as well as peripheral BDNF level and mitochondrial function of individuals with MCI. The present study will provide insight into the interplay among the training program, peripheral BDNF concentration, mitochondrial function, and cognitive function. Importantly, the findings will have clinical implication regarding the training program that is feasible and effective in improving cognitive function of older adults with MCI which ultimately will have great impact on public health as this population is at high risk of progression to AD.

Outcomes
Primary Outcomes
change from baseline Alzheimer's Disease Assessment- cognitive subscale at 3 months
Time Frame: 3 months
Alzheimer's Disease Assessment-cognitive subscale will be assessed at baseline and 3 months. The total scores range from 0-70, with higher scores (≥ 18) indicating greater cognitive impairment.
change from baseline Rey auditory verbal learning score at 3 months
Time Frame: 3 months
Memory will be assessed using Rey auditory verbal learning test.
change from baseline brain-derived neurotrophic factor level at 3 months
Time Frame: 3 months
Level of plasma brain-derived neurotrophic factor (BDNF) will be determined.
change from baseline Trail Making B-A score at 3 months
Time Frame: 3 months
Executive function will be assessed using Trail Making Test part B-A.
Secondary Outcomes
- change from baseline stepping response time at 3 months(3 months)
- change from baseline time to complete Timed Up and Go at 3 months(3 months)
- change from baseline physiological profile assessment score at 3 months(3 months)
- change from baseline Digit Span score at 3 months(3 months)
- change from baseline cellular oxidative stress level at 3 months(3 months)
