Meta-Analysis of Zingiberaceae Effects on Memory and Cognition in Adults

Eighteen randomized controlled trials form the basis of this systematic review and meta-analysis on the cognitive effects of compounds like curcumin and ginger. The analysis found a statistically significant improvement in memory-related outcomes, but no significant effects on other cognitive domains. The work was authored by Desirée Victoria-Montesinos and published on figshare in May 2026.

Use Cases

• Evaluating the efficacy of Zingiberaceae-derived interventions on memory based on the primary meta-analysis outcome
• Assessing the domain-specificity of cognitive effects from nutraceuticals based on the grouped outcome measures
• Informing the design of future clinical trials based on identified limitations like heterogeneity and small study numbers

Strengths

• Includes 18 randomized, double-blind, placebo-controlled clinical trials
• Reports a statistically significant pooled effect size for memory-related outcomes (SMD=0.57)
• Uses a systematic search across four major databases (MEDLINE, Cochrane, Web of Science, Scopus)

Limitations

• The evidence is described as 'very uncertain' due to substantial heterogeneity and a small number of studies
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
