13. Hypertension – The Unseen Enemy
Hypertension, otherwise known as high blood pressure, is an insidious health condition that impacts countless individuals worldwide. It’s often termed as the ‘silent killer’ because it shows no apparent symptoms until it’s significantly advanced and causing other health problems. Beyond its detrimental effects on the cardiovascular system, this condition can also have severe implications for our cognitive health, heightening the risk of dementia.
The connection between hypertension and dementia arises from the fact that our brain’s health is heavily dependent on a robust network of blood vessels. These vessels continuously supply oxygen and nutrients to the brain, ensuring its optimal functioning.
Hypertension can damage these vessels, impairing the necessary blood flow to the brain. This lack of blood flow can then lead to cognitive decline and potentially result in vascular dementia, a form of dementia triggered by reduced or blocked blood flow to the brain.
There’s also another way hypertension can lead to dementia. The condition is one of the most significant risk factors for stroke, a medical emergency where blood flow to a part of the brain is cut off. When a stroke occurs, it can leave behind permanent damage in the brain, leading to a range of cognitive issues, including memory loss and confusion – hallmarks of vascular dementia.
It’s clear that managing blood pressure is a vital component of dementia prevention. Frequent health check-ups, a balanced diet low in sodium and high in fruits and vegetables, regular physical activity, moderate alcohol consumption, and steering clear of smoking can all contribute to keeping blood pressure within a healthy range. If hypertension has already been diagnosed, medication and ongoing medical supervision become critical components of health management. (13)
