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.
