Key Points
Question
Are multidomain interventions associated with better cognitive outcomes than single interventions in older adults with mild cognitive impairment (MCI)?
Findings
This meta-analysis of 28 studies with 2711 participants examined global cognition, attention, executive function, memory, processing speed, and verbal fluency effects. After intervention, significant improvements favoring multidomain interventions were observed in global cognition, executive function, memory, and verbal fluency compared with the single-intervention, active control.
Meaning
In this study, multidomain interventions were more strongly associated with improving global cognition, memory, executive function, and verbal fluency in older adults with MCI than single interventions, but evidence is needed to determine the optimal length of multidomain interventions.
