Dietary Interventions for Dementia Cognition: Systematic Review Results

A systematic review analyzes the influence of diet on cognitive function in patients with dementia. Maria Fernanda Feltrin de Oliveira conducted the review, which included five double-blind, placebo-controlled randomized clinical trials. The review found Souvenaid, Spirulina maxima extract, and blueberry powder showed effectiveness in improving cognition.

Use Cases

• Meta-analysis of clinical trial outcomes based on reported P-values and effect sizes
• Evaluating the efficacy of specific dietary supplements (Souvenaid, Spirulina maxima, blueberry powder) for dementia
• Studying the relationship between nutrition and cognitive domains like memory and visual learning
• Assessing methodological rigor in dementia research based on the inclusion of double-blind, placebo-controlled trials

Strengths

• The review follows PRISMA 2020 guidelines and is registered under PROSPERO (CRD42025623108)
• It includes five double-blind, placebo-controlled randomized clinical trials, a rigorous study design
• Specific quantitative results are reported, such as a 35% reduction in CDR-SB worsening with Souvenaid

Limitations

• The dataset is very small (64.4 KB), indicating limited scope or summary-level data
• Row count and column-level documentation are unknown, which limits suitability assessment
• The sample sizes in the included studies are noted to have great variability, which may affect generalizability
