Author Information

Hypothesis
How does exposure to chronic stressors during mid-life affect cognitive function through physiological dysregulation?
Conclusion
Chronic stressors in mid-life negatively impact cognitive function through physiological changes.
Supporting Evidence
- Cognitive function decreased over time while physiological dysregulation increased.
- Financial strain was linked to cognitive decline through physiological changes.
- Everyday discrimination affected cognitive decline via baseline physiological dysregulation.
Takeaway
If you have a lot of stress in your life when you're middle-aged, it can make it harder for your brain to work well later on.
Methodology
A longitudinal mediation analysis was conducted using data from the Health and Retirement Study.
Potential Biases
Adjustments for age, gender, race/ethnicity, and education may not fully eliminate bias.
Limitations
The study only assessed stressors at baseline and did not account for all potential confounding factors.
Participant Demographics
Adults ages 51-64, with a focus on experiences of discrimination and financial strain.
