Effects of tai chi on cognition and instrumental activities of daily living in community dwelling older people with mild cognitive impairment

This study assessed the effects of Tai Chi on cognitive functions and daily living activities in 160 older adults with mild cognitive impairment (MCI) in Hong Kong. Participants practicing Tai Chi twice weekly for 16 weeks showed significant improvement in cognitive performance (measured by the Mini-Mental State Examination) and their ability to perform daily tasks (instrumental activities of daily living, IADL), compared to a control group with no intervention. However, while these gains were statistically significant, they were modest and within the range of potential measurement error. The findings suggest Tai Chi as a potential, accessible intervention for enhancing cognitive health and maintaining independence among older adults with MCI.

Older adults with mild cognitive impairment should consider practicing Tai Chi twice weekly for at least 16 weeks to improve cognitive functions and daily living abilities. While evidence supports Tai Chi’s benefits, the modest gains observed in this study warrant additional large-scale research. Tai Chi is safe, culturally relevant, and promotes mental and physical well-being, making it a valuable option for enhancing brain health in aging populations.
