High blood pressure is a risk factor for Alzheimer’s disease. Controlling blood pressure through lifestyle changes or medication can help reduce this risk.
Blood pressure is the force of blood pushing against the walls of the arteries, which carry blood from the heart to the rest of the body. Blood pressure can vary depending on various factors, such as age, activity, stress, diet, or medication. Blood pressure can be measured by using a device called a sphygmomanometer, which shows two numbers: systolic and diastolic. Systolic is the pressure when the heart beats and pumps blood, and diastolic is the pressure when the heart rests between beats. Blood pressure can be categorized as normal, elevated, or high (hypertension), depending on the values of these numbers. Blood pressure can have a significant impact on our health, such as:
Affecting the function and structure of the heart, which pumps blood to the brain and other organs
Influencing the elasticity and integrity of the blood vessels, which transport oxygen and nutrients to the brain and other tissues
Modifying the expression of genes and molecules that are involved in the development and progression of Alzheimer’s disease
Altering the levels of hormones and inflammatory markers that regulate mood, memory, and cognition
These effects may also affect the risk of developing Alzheimer’s disease or worsen its symptoms. According to some studies, people who have high blood pressure have a higher risk of developing Alzheimer’s or a related dementia than those who have normal or low blood pressure . The exact mechanism of how blood pressure affects Alzheimer’s is not fully understood, but some possible explanations are:
High blood pressure damages the blood-brain barrier, which protects the brain from harmful substances and pathogens
High blood pressure reduces the blood flow and oxygen supply to the brain, which may cause vascular damage and cognitive impairment
High blood pressure increases the production of amyloid beta, a protein that accumulates in the brain and forms amyloid plaques, which are the hallmarks of Alzheimer’s disease
High blood pressure impairs the clearance of amyloid beta from the brain by reducing the activity of glymphatic system, a network of vessels that drains waste products from the brain
Therefore, controlling your blood pressure may be a simple and effective way to prevent or delay Alzheimer’s disease. There are many ways to control your blood pressure, such as:
Following a balanced and nutritious diet that is low in salt, fat, and sugar, and high in fruits, vegetables, whole grains, lean proteins, healthy fats, and antioxidants
Engaging in regular physical activity that is moderate to vigorous and includes both aerobic and strength training exercises
Avoiding smoking, alcohol, caffeine, and drugs that may increase your blood pressure
Managing stress by practicing relaxation techniques or meditation
Monitoring your blood pressure regularly and consulting your doctor if you have any concerns
The key is to find a blood pressure level that suits your age, gender, health status, and goals. You can also combine blood pressure control with other healthy habits, such as diet, exercise, sleep, mental activity, or social interaction, to maximize your brain health and well-being.
