High Blood Pressure and Alzheimer’s Risk: What’s the Connection?

Chronic hypertension may speed the arrival of Alzheimer’s disease and dementia! Studies show that controlling blood pressure can help lower Alzheimer’s risk. Now Johns Hopkins researchers find that certain medication may be the key. That is because it is found that people who took commonly prescribed blood pressure medications were half as likely to develop Alzheimer’s as those who didin’t.

Researchers have known about the link between blood pressure and Alzheimer’s for years. There is significant evidence to show that chronic high blood pressure will speed the arrival of health problems with aging, such as Alzheimer’s and dementia. However, there is no cure for Alzheimer’s.

Human’s body is a whole system. Heart diseases have connections with brain diseases. Another study shows that the more blood pressure varied over an eight-year period, the greater the risk of dementia. Vascular dementia is the second most common form of dementia after Alzheimer’s disease. It is caused by reduced blood flow to the brain. Blood vessels that supply the brain can weaken just like the heart. In a 2009 Clinic in Geriatric Medicine article, Dr. Thomas Obisesan wrote, “hypertension is recognized as the most consistent risk factor for stroke and Alzheimer’s disease.” So, what’s the connection between these two diseases? High blood pressure can damage small blood vessels in the brain, affecting parts of the brain responsible for thinking and memory. So, can controlling blood pressure through medication also lower Alzheimer’s risk? Actually, it is found that the use of potassium-sparing diuretics reduced the risk of Alzheimer’s nearly 75 percent, while people who took any type of antihypertensive medication lowered their risk by about a third. In other words, if you don’t have Alzheimer’s and you are taking blood pressure medication, you are somewhat less likely to develop dementia. And if you has dementia from Alzheimer’s disease and you took certain antihypertensive medicines, the disease is less likely to progress.

By definition, Alzheimer’s disease is a progressive disease that destroys memory and other important mental functions. In the early stage, people with Alzheimer’s may have difficulty in remembering. The symptoms of Alzheimer’s disease often come on slowly. It might start when someone has trouble recalling things that just happened or putting thoughts into words. It will get worse over time. People in the later stages of the disease usually can’t live along or care for themselves. Nowadays, Alzheimer’s is one of the most common diseases in the world.

High blood pressure may speed the arrival of Alzheimer’s. High blood pressure in people with a genetic risk for Alzheimer’s disease may spur development of brain plaque, a hallmark of the age-related brain disorder. Keeping good vascular health may limit or delay the brain changes associated with Alzheimer’s disease and other aging-related neurological deterioration. Good vascular health by avoiding or controlling diseases like hypertension has important benefits beyond keeping your heart health, thus promoting good brain health. In brief, controlling high blood pressure can prevent the advert of some related diseases. Genetic risk of Alzheimer’s can be reduced by high blood pressure control.

Anyway, high blood pressure is very responsive to lifestyle changes and medical treatment. So, maybe it can a future target for how to prevent Alzheimer’s disease. More importantly, it is important to bring down your blood pressure as soon as possible although it’s not clear if the connection comes from managing the blood pressure better or if the particular drugs might have properties that interfere with other processes relating to Alzheimer’s. But, it is already known that high blood pressure will affect the brain. All in all, high blood pressure is kind of the original causes of other diseases. Lowering hypertension is vital to treating them.
