A secondary search strategy consisting of a manual search in the reference lists of selected articles was also used.Results: A total of nine studies were reviewed including six randomized controlled trials, two non-randomized controlled trials, and one non-randomized prospective study. The studies suggest Tai Chi has impacts on global cognitive functions, visuospatial skills, semantic memory, verbal learning/memory, and self-perception of memory. The effects of Tai Chi on overall cognition for people with mild cognitive impairment are comparable to those in control groups which engaged in exercise.Conclusion: The studies reviewed affirm the potential of Tai Chi to improve short-term cognitive function in the elderly at the onset of dementia.Keywords: behavioral intervention, cognition, dementia, older adult, Tai chi, systematic review
