Why the study?
Are higher diurnal salivary cortisol levels associated with smaller prefrontal cortex surface area in elderly men and women?
Are higher diurnal salivary cortisol levels associated with smaller prefrontal cortex surface area in elderly men and women?
Higher diurnal salivary cortisol levels are associated with smaller medial prefrontal cortex surface area in older adults.
Hypothesis-generating in cross-sectional data; prospective studies needed before any clinical implications for older adults.
This study suggests that the structure of the medial PFC is related to cortisol levels in both elderly women and men.
