ABSTRACT:

Background

Tai Chi integrates multisensory stimuli, including olfactory cues, to enhance cognitive functions such as working memory. This study evaluated the effects of eight-form Tai Chi combined with olfactory stimulation on working memory in older adults with mild cognitive impairment (MCI).
