Hormonal
Normal human aging is characterized by a significant increase in mean daily serum cortisol levels and a decrease in DHEA, leading to an elevated cortisol-to-DHEA ratio that impairs stress recovery and accelerates neurodegeneration.
As you age, your body naturally produces more cortisol (stress hormone) and less DHEA (anti-aging hormone). This imbalance impairs your ability to recover from stress and increases the risk of cognitive decline, muscle loss, and metabolic issues. Managing stress and maintaining physical activity are critical to mitigating these hormonal shifts.
Most notable is the general increase in mean daily serum cortisol levels in the elderly... In contrast to the increase in glucocorticoid levels, other adrenocortical hormones, particularly serum aldosterone and DHEA... show significant decreases in the elderly.
Why this rating
The paper is a comprehensive review citing multiple studies, though it notes some conflicting evidence regarding cortisol levels in specific subgroups.

- Chronic elevation of glucocorticoids (cortisol) in the elderly impairs the ability to recover from stressful stimuli and contributes to structural brain changes, including hippocampal atrophy and amygdala dysfunction.Good
- The age-related decline in DHEA and DHEAS, combined with stable or elevated cortisol, creates a high cortisol-to-DHEA ratio that contributes to immunosenescence, frailty, and increased mortality risk.Good
