Hypertension's Silent Threat: Brain Health at Risk
High blood pressure, or hypertension, is a common problem where blood pushes too hard against the walls of your blood vessels.
It can silently damage your brain over time.
It can make it hard to think and remember things and can lead to serious problems like strokes and dementia.
This is because high blood pressure can harm the brain's blood vessels, making it hard for the brain to get the blood and nutrients it needs.
The good news is that if you find and treat high blood pressure early, you can protect your brain and stay sharp as you get older.
Keeping blood pressure under control is crucial for keeping your brain healthy!
Hypertension affects 1.28 billion adults globally, and is expected to rise.
Uncontrolled hypertension is a major public health issue, affecting less than 20% of those with the condition.
Hypertension is a leading cause of stroke and cognitive decline due to damage to the brain's blood vessels.
Chronic high blood pressure can weaken the blood-brain barrier, increasing the risk of dementia.
Early detection and effective management of hypertension can reduce the risk of cognitive decline.
