High blood pressure
The effect of high blood pressure on brain health.
Share this article
High blood pressure is one of the most underestimated risk factors for brain health. Many people don't feel anything, but damage can occur over the years. Not only to the heart, but also to the brain. Therefore, high blood pressure plays an important role in the LIBRA score.
Research shows that particularly elevated blood pressure in middle age is associated with a higher risk of memory problems and dementia later on. It's not only about strokes, but also about small, silent changes in the brain that slowly accumulate.
What do we mean by high blood pressure?
Blood pressure is the pressure at which blood flows through your vessels. It is expressed in two values:
Systolic: the pressure when the heart contracts
Diastolic: the pressure when the heart relaxes
Generally:
Normal: lower than 120 over 80
Elevated: 120 to 129 over lower than 80
High blood pressure: 130 over 80 or higher
Even slightly elevated values can, if they persist for years, cause damage to the small blood vessels in the brain.
Why is high blood pressure bad for your brain?
Damage to Small Blood Vessels
The brain is full of very fine blood vessels. Prolonged high pressure damages these vessels, which can lead to small infarcts and white matter damage. You often see this type of damage only on a scan, but it does affect thinking, planning, and memory.
Reduced Blood Flow
Due to stiffer and narrower vessels, the blood flow becomes less flexible. Brain areas then receive less oxygen and nutrients, especially during exertion or stress.
Interaction with Other Risk Factors
High blood pressure often occurs together with diabetes, overweight, and high cholesterol. This combination increases the risk of cognitive decline more strongly than any factor alone.
Common Misunderstandings
“I don't notice anything, so my blood pressure must be okay”
High blood pressure usually does not give clear symptoms. That's why it is often called a silent risk factor. Damage can occur before you feel anything.
“Only the systolic pressure is important”
Both values matter. An elevated diastolic pressure or an unfavorable combination can equally pose risks for the brain and blood vessels.
“Higher blood pressure is normal at an older age”
As you age, blood pressure often rises, but that doesn't mean it's harmless. Lowering blood pressure also has benefits for brain health in older age.
“Medication is worse than slightly high blood pressure”
Well-adjusted medication reduces the risk of damage to the heart and brain. The risks of untreated high blood pressure are usually greater than the side effects of medication.
What can you do yourself?
High blood pressure is one of the most modifiable risk factors. Small improvements can make a difference.
Exercise regularly
Daily physical activity helps lower blood pressure. Consider brisk walking, cycling, or swimming. Shorter periods spread throughout the day also count.
Watch your salt intake
Many people unknowingly consume too much salt, especially through processed foods. Eating fewer ready-made meals and reducing sauces and snacks can help quickly.
Eat a varied and high-fiber diet
Vegetables, fruits, whole grains, and legumes provide potassium and fibers that positively influence blood pressure.
Limit alcohol
Alcohol can raise blood pressure, especially with daily consumption. Drinking less often has measurable effects.
Ensure enough relaxation and sleep
Chronic stress and poor sleep keep blood pressure elevated. Rest periods, breathing exercises, and a regular sleep routine help reduce it.
Medication and monitoring
If lifestyle changes are not sufficient, medication may be necessary. This is not a failure, but a way to prevent damage. It is important to:
Measure blood pressure regularly
Follow appointments with the general practitioner
Take medication consistently
Discuss side effects instead of stopping by yourself
Home measurements, spread over several days, often provide a better picture than a single measurement at the clinic.
When should I be extra alert?
Extra attention is important if you:
Have diabetes
Have had a heart or vascular disease
Have kidney problems
Have many heart and vascular diseases in the family
In those cases, it pays to closely monitor blood pressure and make timely adjustments.
In short
High blood pressure often works quietly, but it has significant effects on your brain. By measuring regularly, maintaining healthy habits, and using medication when necessary, you can significantly reduce the risk of brain damage and cognitive decline. Every step down in blood pressure is a win for your brain.
