Hypothesis
Does inflammation mediate the relationship between chronic stress and cognitive function, with sex and age as moderating factors?
Conclusion
Chronic social isolation stress significantly impacts cognitive function, with inflammation playing a mediating role, particularly influenced by sex.
Supporting Evidence
- Long-term stress is linked to worse cognitive outcomes and higher dementia risk, especially in women.
- Chronic stress leads to inflammation, which is known to affect cognitive function.
- Social isolation stress was found to significantly predict cognitive function measures after correction.
Takeaway
When people feel lonely and stressed, it can hurt their thinking skills, and inflammation in the body might be a reason why, especially for women.
Methodology
The study analyzed the impact of social isolation stress on cognitive function using Poisson and linear regressions.
Participant Demographics
Participants were from the MIDUS Refresher 1 cohort, with a focus on sex and age differences.
