Multidomain interventions are increasingly used, but their cognitive benefits and the influence of intervention dose and component mix in MCI remain uncertain.  \nObjective  \nThis study aimed to first compare the cognitive outcomes of single-domain and multidomain interventions in older adults with MCI, and second, to examine the influence of intervention parameters such as intensity, density, and component composition on cognitive improvements.  \nMethods  \nSix international databases, including PubMed, Embase, Cochrane CENTRAL, Web of Science, PsycINFO, and CINAHL, were searched from inception to November 2025. Two reviewers independently screened, extracted, and critically appraised the studies. Random-effects meta-analyses pooled standardized mean differences (Hedges' g) for post-intervention global cognition and cognitive domains. Meta-regression and subgroup analyses explored design and implementation factors. One-stage robust error meta-regression modeled the dose–response relationship between intervention intensity, sessions, intervention density, and component composition with cognitive outcomes.  \nResults  \nA total of 28 trials (3,377 participants) were included. Pooled analyses showed that multidomain interventions were associated with statistically significant improvements in global cognition, memory, executive function, verbal fluency, and attention (Hedges' g = 0 .31–0. 50) . A larger but less precise benefit was observed for visuospatial ability (Hedges' g = 0 .80), whereas the pooled estimate for processing speed did not reach statistical significance [Hedges' g = 0 .48, 95% CI (-0 . 12, 1 .08)] . Dose–response models suggested the optimal intervention density was found to be approximately 36.8 minutes/session, with greater cognitive benefits. Notably, the optimal percentage of the total intervention time for physical activity was approximately 43 . 6%, beyond which further increases offered no additional cognitive gains.  \nConclusions  \nMultidomain interventions were linked to modest to moderate improvements in both global and domain-specific cognition in older adults with MCI. Multidomain programs may be more successful and feasible if session density is optimized and the proportionate contribution of physical activity is balanced. To maximize cognitive benefits, the ideal intervention intensity, density, and percentage of physical activity are essential. The creation of multidomain intervention protocols to stop cognitive decline and postpone the onset of dementia in older adults is supported by these findings. To improve their clinical applicability, future studies should investigate long-term effects and fine-tune these intervention parameters.  \nTrial registration  \nThe protocol was registered on PROSPERO (registration number: CRD420261283039, date created: 13 January 2026) .  \n1.
