Blood micronutrients modified associations between blood heavy metals and cognitive decline in a nationally representative cross-sectional study

Key Points

• Cognitive decline is significantly impacted by the levels of heavy metals, revealing critical connections.
• The analysis found higher concentrations of certain micronutrients correlated with less cognitive decline in individuals exposed to heavy metals.
• A cross-sectional assessment examined associations between heavy metals and cognitive decline while factoring in blood micronutrient levels.
• Findings suggest that enhancing micronutrient intake may be crucial for mitigating cognitive decline linked to heavy metal exposure.
