研究问题
Meta-analyses report possible cognitive benefits in mild cognitive impairment (MCI), but dementia prevention has not been established ( Chen et al., 2024 ; Shao et al., 2024 ).；The aim is to define where Tai Chi may complement established care and what methodological standards are required for credible trials.；Because these reviews combine interventions and mostly small studies, they provide indirect, hypothesis-generating support for Tai Chi rather than evidence of a Tai Chi-specific neural mechanism.
方法
Eligible designs included systematic reviews, meta-analyses, randomised trials, pragmatic trials, cohort studies, clinical guidelines, consensus statements, and major methodological or public health reports.；Timing and trajectory may modify the association ( Lee et al., 2021 ), and a large Danish cohort found associations across early-, mid-, and late-life depression ( Elser et al., 2023 ).；Irish longitudinal data linked sub-recommended activity to fewer depressive symptoms and lower odds of major depression ( Laird et al., 2023 ), and another population cohort found lower depression risk across activity intensities and frequencies ( Lima et al., 2024 ).
核心结论
（原文未给出可直接抽取的对应表述）
局限
Exercise is supported for depression, and benefits may occur below conventional activity targets ( Noetel et al., 2024 ; Pearce et al., 2022 ); however, frailty, pain, fear of falling, low motivation, and cognitive impairment can make standard aerobic or resistance programmes difficult to start or sustain.；It should be evaluated as a multicomponent behavioral intervention—not as a stand-alone or curative alternative to evidence-based mental-health care ( Wayne and Kaptchuk, 2008b ).
