Objectives:
Individuals with mild cognitive impairment (MCI) are at high risk for developing dementia. Physical exercise is a promising intervention for cognitive decline. Systematic reviews regarding the effects of physical exercise on cognitive and psychological outcomes among MCI patients are limited and a systematic review exploring the effects of exercise modalities on the results has not been conducted. Therefore, this review article has been conducted.
Do individuals with mild cognitive impairment benefit from physical exercise?
Study design:
This review article included 11 studies. The exercise interventions can be classified into 3 types: (a) aerobic exercise, (b) resistance exercise and (c) multi-modal exercise.
Results and conclusions:
The investigators found that physical exercise had beneficial effects for global cognition [SMD = 0.30, 95% CI = 0.10-0.49, p = 0.002].
The investigators found subgroup analysis demonstrated that aerobic exercise programmes were consistently associated with medium effect size [SMD = 0.54-0.58].
The investigators found, however, the effects of physical exercise on domain-specific cognitive function and psychological outcomes in mild cognitive impairment patients remained inconclusive.
The investigators found sensitivity analysis showed that types of control exerted influence on the outcomes.
The investigators concluded that physical exercise, aerobic exercise in particular, benefits global cognition in mild cognitive impairment patients. The evidence of physical exercise on domain-specific cognitive function and psychological outcomes remains unclear, more trials with rigorous study design are necessary to provide the evidence.
