Cardiovascular diseases
The impact of cardiovascular diseases on brain health.
Cardiovascular diseases are often seen as a heart problem, but they also have significant effects on the brain. The blood vessels of your heart and those of your brain are part of the same system. If that system is damaged, it almost always affects both.
Research shows that people with cardiovascular diseases have a higher risk of cognitive decline and dementia. Therefore, these conditions are included as important risk factors in the LIBRA score for brain health.
What do we mean by cardiovascular diseases?
Cardiovascular diseases include conditions where the blood vessels or heart are damaged, such as:
- narrowing of the coronary arteries
- a previous heart attack
- angina pectoris, chest pain due to lack of oxygen
- treatments such as angioplasty or stent placement
These conditions indicate that the vascular system is vulnerable, not only in the heart, but also towards the brain.
Why are cardiovascular diseases unfavorable for your brain?
Shared Vulnerability of Blood Vessels The processes that cause narrowing and stiffening of the vessels in the heart also occur in the blood vessels that supply the brain with blood. Atherosclerosis is not a local problem but a systemic issue.
Reduced Blood Flow Damaged vessels are less able to respond to the brain’s needs. This can lead to temporary or permanent shortages of oxygen and nutrients, affecting memory and attention.
Increased Risk of Strokes Cardiovascular diseases increase the risk of cerebral infarctions and hemorrhages. These can directly lead to cognitive problems, but small, silent infarctions also contribute to gradual decline.
Correlation with Other Risk Factors Cardiovascular diseases often occur alongside high blood pressure, diabetes, and high cholesterol. This combination increases the risk of cognitive decline.
Common Misunderstandings
“My heart problem is separate from my brain” The heart and brain are directly connected through the vascular system. What harms the blood vessels affects both organs.
“Once the heart is treated, the risk is gone” Treatment reduces risks, but the underlying vascular vulnerability often remains. Continued focus on lifestyle and monitoring is important.
“After a heart problem, I should mainly rest” Rest is sometimes necessary, but prolonged inactivity is unfavorable. Tailored exercise is actually part of recovery and brain health protection.
“Stress after a heart problem is normal” Anxiety and stress are common after a heart problem, but prolonged stress burdens the brain and vascular system. Attention to this is important.
What can you do yourself?
Follow medical advice carefully Medications such as blood thinners, cholesterol-lowering drugs, or blood pressure medication are designed to prevent further damage. Regular use and monitoring are important.
Keep moving within your limits Exercise improves the condition of blood vessels and supports recovery. This can be under supervision, for example through cardiac rehabilitation or a tailored exercise program.
Pay attention to diet and lifestyle A diet rich in plant-based products, low in saturated fat, and minimally processed foods supports both heart and brain health.
Focus on stress and recovery Relaxation, sleep, and coping with uncertainty after a heart issue contribute to bodily stability and brain health.
When additional guidance is helpful
When additional help is beneficial
Extra support can help if:
- anxiety or uncertainty continues to dominate daily life
- exercise feels difficult without guidance
- multiple risk factors converge
The general practitioner or specialist can help think about appropriate support.
In short
Cardiovascular diseases are a clear signal that the blood vessels in the brain are also vulnerable. By combining medical treatment with lifestyle changes, exercise, and a focus on recovery, you not only protect your heart but also safeguard your brain health in the long run.

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.
