Do you remember the threads on antihypertension drugs slowing PD and AD?
Gary Smith says,
"If we could halt AT1 with an existing type of drug known as an angiotensin receptor blocker, we can not only switch off the inflammation, but also allow the body to recognise the disease".
Anti hypertension (high blood pressure) drugs such as Angiotensin receptor blockers have already been shown to have a very beneficial effect.

Angiotensin II receptor antagonists, also known as angiotensin receptor blockers (ARBs), AT1-receptor antagonists or sartans, are a group of pharmaceuticals which modulate the renin-angiotensin-aldosterone system. Their main use is in hypertension (high blood pressure), diabetic nephropathy (kidney damage due to diabetes) and congestive heart failure.

In 2008 they were reported to have a remarkable negative association with Alzheimer's Disease. A retrospective analysis of five million patient records with the US Department of Veterans Affairs system found that different types of commonly used anti-hypertensive medications had very different AD outcomes. Those patients taking angiotensin receptor blockers (ARBs) were 35—40% less likely to develop AD than those using other anti-hypertensives. (Preliminary unpublished data)[1][2]
