The effectiveness of Tai Chi for short-term cognitive function improvement in the early stages of dementia in the elderly: a systematic literature review

Clin Interv Aging. 2019 May 8;14:827-839. doi: 10.2147/CIA.S202055. eCollection 2019.

Abstract

Purpose: This systematic review examines intervention studies using Tai Chi in the early stages of dementia to determine the effectiveness of Tai Chi for the short-term improvement of cognitive functions for elderly persons with the disease. Methods: A keyword search was done in PubMed/MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), and Cochrane Library databases using keywords such as Tai Chi, Dementia*, and cognition. 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: Tai chi; behavioral intervention; cognition; dementia; older adult; systematic review.
