Hypothesis
This study investigates how multidimensional early-life circumstances contribute to dementia risk in later life, particularly through the role of DNA methylation age acceleration.
Conclusion
The study found that early-life circumstances significantly impact dementia risk, with DNA methylation age acceleration acting as a key mediator.
Supporting Evidence
- Adverse family education environments were linked to increased dementia risk.
- Positive school experiences were found to be protective against dementia.
- DNA methylation age acceleration mediated a significant portion of the association between maternal education and dementia risk.
Takeaway
The way we grow up can affect our brain health when we get older, and some biological changes in our DNA can help explain this.
Methodology
The study used multivariate regression analyses to assess the relationship between early-life circumstances and dementia risk in a sample of American adults aged 50 and older.
Participant Demographics
