This meta-analysis reviewed nine randomized controlled trials involving 614 participants to evaluate the effects of electroacupuncture on senescence-associated cognitive impairment (SACI). The findings indicated that electroacupuncture led to short-term improvements in cognitive scores (MoCA and MMSE) and reduced IL-6 levels, with larger effects observed in mild cognitive impairment subgroups. However, significant methodological heterogeneity was noted across studies.
Key findings
- Electroacupuncture was associated with short-term improvements in MoCA and MMSE scores.
- A reduction in peripheral pro-inflammatory cytokine IL-6 was observed following electroacupuncture.
- Pooled effect sizes were moderately larger in MCI subgroups compared to early Alzheimer's disease patients.
- Substantial methodological heterogeneity across trials limits cross-study comparability.
Why it matters
Understanding the potential of electroacupuncture to mitigate neuroinflammation and improve cognitive function in aging populations is crucial, especially as the prevalence of age-related cognitive decline increases. This research highlights a promising intervention that may enhance patient outcomes.
What to keep in mind
Severe methodological heterogeneity across trials, including inconsistent acupoint prescriptions and variable treatment cycles, limits the comparability and reproducibility of results.
