Effects and mechanisms of Tai Chi on mild cognitive impairment and early-stage dementia: a scoping review

This scoping review evaluated 14 studies on Tai Chi's effects on mild cognitive impairment (MCI) and early-stage dementia. Findings suggest Tai Chi may enhance global cognitive function, memory, and executive skills, while improving balance and reducing arthritis pain. However, results on depressive symptoms and perceptual-motor skills were inconsistent. Mechanistic studies in healthy adults showed increased brain connectivity and gray matter volume with Tai Chi practice, potentially explaining its cognitive benefits. Despite promising results, variations in study quality and methodology limit conclusions. Tai Chi appears to be a safe, non-pharmacological intervention to slow cognitive decline in at-risk populations.

Engage in Tai Chi for 30–60 minutes, 2–3 times per week, to potentially improve memory, balance, and executive function. Suitable for older adults, Tai Chi offers a low-intensity, accessible approach to maintaining brain health and physical function. While benefits are supported by some studies, the evidence remains inconclusive due to methodological inconsistencies. Further research is needed to confirm its effectiveness in diverse populations.
