Hypertension puts You at Risk of Dementia

Studies show that having hypertension (high blood pressure) increases a person's risk of developing forms of dementia such as Alzheimer's disease and vascular dementia.

Dementia is a progressive brain disorder characterized by worsening cognitive deficit like memory loss. What makes this disease terrifying is the fact that currently, there is still no known cure for it.

It is imperative to find better ways to manage this incurable disease and one good way to do so is to explore ways to prevent dementia from forming in the first place. The discovery that high blood pressure can lead to dementia gives us a good insight. High blood pressure is a growing burden globally. According to the Centers for Disease Control and Prevention, 1 in every 3 Americans suffer from high blood pressure.


A BP of 130 mmHg is a risk

Blood pressure of 130 mmHg is previously considered as prehypertensive, but a recent study reveals that maintaining this blood pressure can still put you at risk.

A study consisting of 8639 people reveals that having a sustained systolic blood pressure of equal to or more than 130 mmHg by age 50 years old increases the risk of dementia.

When a person has high blood pressure, risks of blod clots and blood vessel weakening increases, which can compromise the oxygen and nutrient supply of the brain. High blood pressure is linked to stroke (brain attack) which can lead to a significant mental and physical deficit. While the incidence of dementia is higher among people who've had stroke than those who have not, high blood pressure still increases a person's risk of developing dementia even without having a brain attack.


The fight is tough

Controlling high blood pressure is a significant intervention to reduce risk of developing dementia.

According to the World Health Organization (WHO) 1.1 billion adults have high blood pressure, but less than 1 in every 5 people have it under control.

Awareness is a crucial step so don't hesitate to get in touch with your health care provider to explore options to help you manage hypertension before it's too late.
