The autonomic nervous system undergoes change with aging
Physiology
- with physical or emotional stress, greater & more prolonged activation of the
- sympathetic nervous system
- greater & prolonged increase in plasma norepinephrine
- hypothalamic-pituitary-adrenal axis
- greater & prolonged increase in plasma cortisol
- sympathetic nervous system
- higher resting heart rate & lower heart rate variability result from age-associated changes in autonomic function
- common in the elderly
- associated with functional decline[2]
- age-associated changes in baroreceptor sensitivity[3]
