Primary hypertension, also known as essential hypertension, is the result of a consistent elevation of the force of blood being pumped throughout the body, whereas secondary hypertension is the result of high blood pressure due to another medical condition.> Diseases that can cause secondary hypertension include diabetic nephropathy, glomerular disease, polycystic kidney disease, cushing ...

Get your blood pressure checked regularly. Hypertension is a leading cause of stroke and heart disease, so checking your numbers is important. (A healthy blood pressure reading is less than 120/80 ...
Baroreceptors respond very quickly to maintain a stable blood pressure, but their responses diminish with time and thus are most effective for conveying short term changes in blood pressure. In people with essential hypertension the baroreceptors and their reflexes change and function to maintain the elevated blood pressure as if normal. The ...
Baroreceptors are active even at normal blood pressures so their activity informs the brain about both increases and decreases in blood pressure. The body contains two other, slower-acting systems to regulate blood pressure: the heart releases atrial natriuretic peptide when blood pressure is too high, and the kidneys sense and correct low ...
“High blood pressure can damage blood vessels in the brain, leading to vascular issues that increase dementia risk,” says Smita Patel, D.O., FAASM, a board-certified neurologist with Endeavor ...
The impairment of cerebral blood flow that underlies hypertensive encephalopathy is still controversial. Normally, cerebral blood flow is maintained by an autoregulation mechanism that dilates arterioles in response to blood pressure decreases and constricts arterioles in response to blood pressure increases. This autoregulation falters when ...
