High blood pressure
The effect of high blood pressure on brain health.
High blood pressure is one of the most underestimated risk factors for brain health. Many people do not feel it, but damage can occur over the years. Not only to the heart, but also to the brain. That is why high blood pressure plays an important role in the LIBRA score.
Research shows that especially increased blood pressure in middle age is associated with a higher chance of memory problems and dementia later on. It is 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 with which blood flows through your vessels. It is expressed in two values:
- Systolic pressure: the pressure when the heart contracts
- Diastolic pressure: the pressure when the heart relaxes
Generally applicable:
- Normal: lower than 120 over 80
- Elevated: 120 to 129 over less than 80
- High blood pressure: 130 over 80 or higher
Even slightly elevated values, if they persist for years, can 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 strokes and white matter damage. This kind of damage often only shows up on a scan, but it does affect thinking, planning, and memory.
Poor Circulation With stiffer and narrower vessels, circulation becomes less flexible. Brain regions then receive less oxygen and nutrients, especially during exertion or stress.
Collaboration 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 than each factor individually.
Common Misunderstandings
“I don’t notice anything, so my blood pressure will be fine” High blood pressure usually does not give clear symptoms. This is 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 to the brain and blood vessels.
“Higher blood pressure is normal at an older age” Blood pressure often increases with age, but that does not mean it is harmless. Even at an older age, lowering blood pressure has benefits for brain health.
“Medication is worse than slightly high blood pressure” Properly 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 controllable risk factors. Small improvements can already make a difference.
Exercise regularly Daily physical activity helps lower blood pressure. Think of brisk walking, cycling, or swimming. Shorter moments spread throughout the day also count.
Watch your salt intake Many people unknowingly consume too much salt, especially through processed foods. Eating less ready-made meals and fewer sauces and snacks helps quickly.
Eat a varied and fiber-rich diet Vegetables, fruits, whole grain products, and legumes provide potassium and fibers that favorably influence blood pressure.
Limit alcohol Alcohol can raise blood pressure, especially with daily use. Drinking less often already has a measurable effect.
Ensure sufficient relaxation and sleep Chronic stress and poor sleep keep blood pressure higher. Rest moments, breathing exercises, and a regular sleep pattern contribute to reduction.
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:
- Regularly measure blood pressure
- Follow appointments with the general practitioner
- Consistently take medication
- Discuss side effects instead of stopping on your own
Measurements taken at home, 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 experienced a cardiovascular disease
- Have kidney problems
- Have a lot of cardiovascular diseases in the family
In those cases, it pays off to closely monitor blood pressure and adjust timely.
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.

Frequently asked questions
How does Remind help me recognise changes in my brain in time?
Remind monitors multiple aspects of your brain health over time, such as thinking, memory, speech and daily functioning. By combining these signals you get a clear picture of what is normal for you and which changes deserve attention. This provides peace of mind and prevents you from reacting too late to subtle shifts.
Is Remind the same as a medical examination or diagnosis?
No. Remind is a wellbeing product and not a medical device. The app provides insight into patterns and changes but does not replace a doctor or a diagnosis. If you have concerns about your memory or functioning, always discuss your results with your GP.
How reliable are the measurement methods Remind uses?
Remind uses methods based on validated questionnaires and digital tests that are also applied in research and clinical settings. We combine multiple sources, such as speech, memory, behaviour and lifestyle, so that you do not get a single snapshot but a complete and reliable picture that grows as you use the app.
What happens to my data? Is anyone listening or reading along?
No. Remind never stores conversations or the content of messages. All data is processed with encryption, and we only use patterns such as pace, rhythm or accuracy, not content. You always decide which data you share and with whom.
What does my Remind brain age give me?
Your Remind brain age shows how your brain is functioning compared with what is normal for your age. You receive practical advice to strengthen your brain health and can see over time whether your actions have an effect. This helps you make informed choices and stay in control.
