Why does hypertension commonly develop in elderly individuals with arteriosclerosis?

💡 Explanation

Hypertension develops due to impaired baroreceptor signalling because increased arterial stiffness reduces the vessel wall's ability to distend in response to pressure changes, desensitizing baroreceptors. Therefore, blood pressure isn't effectively regulated, rather than the sensitivity increasing or hormonal responses compensating.
