Background Mild cognitive impairment is an age-related cognitive disorder which is associated with frequent memory lapses, impaired judgement, and progressive functional decline. If untreated early, 39.2% of people with mild cognitive impairment could progress to develop dementia. However, there are currently no approved pharmacological interventions to treat the condition, which lead researchers to explore non-pharmacological options, such as dance therapy. Objectives This systematic review aimed to examine the effectiveness of dance interventions on cognition, neuroplasticity, physical function, depression, and quality of life in older adults with mild cognitive impairment. Methods Seven databases were systematically searched from their respective inception dates to 31 March 2020. Relevant randomized controlled trials (RCTs) were screened and assessed for risk of bias. Eight RCTs evaluating dance interventions were included. Results Results showed that dance interventions had a significant moderate effect on global cognition (SMD=0.54, Z = 3.55, p<0.001), significantly improved memory (SMD=0.33, Z = 3.97, p<0.001), visuospatial function (SMD=0.42, Z = 2.41, p = 0.02), and language (SMD=0.39, Z = 2.69, p = 0.007). We found that dance interventions produced a significant moderate effect on physical function (SMD=0.55, Z = 3.43, p<0.001), and a significant effect on quality of life (SMD=0.93, Z = 5.04, p<0.0.001). Conclusion Dance is a non-pharmacological and inexpensive intervention that can be implemented for older adults on a large scale. It can slow down the cognitive deterioration of older adults with mild cognitive impairment. However, the findings should be interpreted with caution due to the heterogeneity in intervention designs. Rigorous design studies with long-term follow-ups, neuroimaging, biological markers, and comprehensive neuropsychological assessment are required to understand the mechanism of dance interventions and demonstrate its efficacy for older adults with mild cognitive impairment. The protocol was registered on PROSPERO (CRD42020173659).
