High blood pressure, or what doctors refer to as hypertension, has long been known to increase the risk of developing Alzheimer's Disease and other forms of dementia. To some degree, this is due to the fact that high blood pressure increases the risk of developing heart disease, which is a major risk factor for dementia. However, high blood pressure itself is known to cause subtle damage to the fine network of blood vessels in the brain. Over time this results in inflammation, hardening of the arteries, poor blood flow, and secondary damage to the brain tissue that depends on these blood vessels for a steady supply of oxygen, fuel and nutrients. These insults to the brain increase the risk of Alzheimer's Disease. 
Reducing blood pressure, by diet, exercise, and weight loss, is known to improve the chances of avoiding Alzheimer's Disease. A variety of antihypertensive medications that lower blood pressure have also been found to reduce the risk of dementia. Although treatment of high blood pressure itself reduces the risk of Alzheimer's Disease, recent evidence suggests that certain antihypertensive medications are more effective than others in helping prevent this disease. The mechanisms by which these blood pressure medications act in the brain may determine the degree to which they are able to help prevent dementia. To get more: http://www.huffingtonpost.com
