Hypothesis

There is a positive association between severe periodontitis and the risk of cognitive decline, mediated by inflammatory biomarkers.

Conclusion

Lower cognitive performance correlates with a higher likelihood of severe periodontitis, and alkaline phosphatase enhances this association.

Supporting Evidence

  • Each one-point increase in cognitive function score was associated with a 2% decrease in the odds of severe periodontitis.
  • ALP was a significant effect modifier in the relationship between severe periodontitis and cognitive decline.
  • Individuals with severe periodontitis had lower mean cognitive function scores compared to those without.

Takeaway

If older people have bad gum disease, it might make their memory worse. A special enzyme in the blood can make this connection stronger.

Methodology

Cross-sectional analysis of NHANES data from 2013-2014 using logistic regression to assess the association between severe periodontitis and cognitive decline.

Potential Biases

Potential misclassification bias due to reliance on non-clinical cognitive assessments.

Limitations

The study's cross-sectional design limits causal interpretation, and there was no clinical assessment data for cognitive impairment.

Participant Demographics

Participants were aged 65 and older, with a mix of males and females.
