A systematic review of the effect and mechanism of Daoyin therapy on improving mild cognitive impairment in older adults

Abstract

Background

Age-related cognitive decline is a pervasive problem in the aging population. Daoyin therapy is a mind-body movement characteristic of traditional Chinese medicine (TCM). Increasing evidence has reported its usefulness in improving cognitive function among different populations. However, there is no systematic review to assess the effect and mechanism of Daoyin therapy on mild cognitive dysfunction (MCI) in older adults.

Objective

To systematically review the evidence on the effect and mechanism of Daoyin therapy on MCI in older adults.

Results

Taichi, Baduanjin, and Yijinjing can improve cognitive function. Qigong and Wuqinxi can enhance the physical and cognitive functions related to balance, muscle strength, physical endurance, postural control, and flexibility. Taichi, Baduanjin, and Wuqinxi can improve the cognitive function of older adults and alleviate the symptoms associated with MCI through multiple mechanisms. The underlying mechanisms include activating the expression of signals and changing their connections in different brain regions, increasing brain capacity, and regulating brain-derived neurotropic and inflammatory factors.

Conclusion

In summary, the existing evidence from RCTs suggests that traditional Daoyin therapy, such as Taichi, Baduanjin, and Wuqinxi, is a promising strategy that can improve cognitive function and delay the onset of dementia in older adults with MCI by altering structural and neural activities and modulating other factors.
