Key Takeaways – High Blood Pressure & Alzheimer’s Risk
-
High blood pressure (hypertension) is linked to an increased risk of dementia and Alzheimer’s disease.
-
Hypertension damages blood vessels, reducing efficiency and increasing brain plaque and tangle formation.
-
Low blood pressure can also impair memory and cognition in elderly individuals.
-
Maintaining blood pressure in the healthy “Goldilocks zone” is key for brain health.
-
Risk factors for high BP include excess salt, inactivity, smoking, and excessive alcohol consumption.
-
Healthy lifestyle habits—balanced diet, regular exercise, no smoking, and limited alcohol—support optimal blood pressure.
-
Age, family history, and head injuries also contribute to Alzheimer’s risk.
-
Managing blood pressure can help reduce risks for heart disease, stroke, and cognitive decline.
-
Understanding first aid equips you to assist those affected by dementia-related conditions.
-
CPR First Aid’s Liverpool first aid courses provide lifesaving skills and practical emergency response training.
Scientists are still unable to pinpoint the exact cause of Alzheimer’s disease. Despite that, several risk factors have been mapped. One that we’ll look at today is high blood pressure.
Does this factor contribute to the development of memory conditions like Alzheimer’s? Let’s find out.
Is High Blood Pressure a Risk Factor for Alzheimer’s?
Increased blood pressure, also known as hypertension, occurs when the force of blood against the walls of arteries is too high. This happens when there is too much salt in the diet, not enough physical activity, smoking, or drinking too much alcohol.
This type of blood pressure is a significant risk factor for heart disease and stroke, which are two of the leading causes of death in the world.
According to a study done in 2015, higher blood pressure may also be a risk factor. The study found that people with increased blood pressure were more likely to develop dementia than those without.
What Does Hypertension Do to the Mind?
The strong flow of blood makes it into blood vessels. This damages these vessels, requiring them to work harder to pump blood throughout the body. The damage ultimately takes away efficiency.
If left unchecked, it will eventually damage and narrow the arteries. It will then lead to heart problems and strokes.
A study done by Neurology looked into the brains of the elderly who had hypertension. Upon checking their brains, they found an increased number of tangles and plaques due to strokes.
While this doesn’t exactly prove a causal link between the two, it does prove that hypertension increases the likelihood of these tangles and plaques from invading the brain and affecting the person.
A Warning Against Low Blood Pressure
While higher blood pressures seem to lead to, or at least increase the risk, of these mental conditions, going lower isn’t the answer.
A study a few years back showed that elderly people with lower-than-usual blood pressure were also at risk of having their brains’ memory and cognition affected.
Thus, low blood pressure is also dangerous and can have negative effects on the brain. Both high and low blood pressure carry their own risks.
The goal is always to maintain a balance in the Goldilocks zone: not too high or too low.
How to Control Blood Pressure?
Since both high and low blood pressure are risk factors, taking steps to control them is essential.
Eat a Healthy Diet
This means eating plenty of fruits, vegetables, and whole grains and limiting salt, saturated fat, and sugar.
Get Regular Exercise
Exercise helps lower blood pressure by strengthening the heart. The CDC recommends at least 150 minutes of moderate-intensity or 75 minutes of high-intensity aerobic activity per week.
Don’t smoke
Smoking damages the lining of blood vessels and makes them less flexible, which can lead to increased blood pressure.
Limit Alcohol Intake
Drinking too much alcohol can also increase blood pressure. The American Heart Association (AHA) recommends that men consume no more than two drinks per day and women consume no more than one drink per day.
Be Aware of the Risk Factors
Apart from blood pressure, diet, smoking, and alcohol intake, many other risk factors can contribute to these conditions. It is important to be aware of them and use this knowledge to circumvent them and the memory problems down the line.
Age
Our risk of developing these conditions within our brains increases as we age. This is because the longer we live, the more time we have to create these conditions.
Family History
If you have a family member experiencing these conditions, you may be at an increased risk of developing these conditions yourself. This is especially true if the affected family member develops the condition at a young age.
Head Injuries
While the link between head injuries and this condition is not fully understood, research has shown that there may be a connection between the two. One theory is that head injuries can cause a build-up of tau protein in the brain, which is one of the hallmark characteristics that cause memory loss and loss of coordination, to name a few.
Hold On
Again, memories are precious. While memory loss will come sooner or later, it is important to do everything we can to hold on as long as possible. Preventing high blood pressure from developing Alzheimer’s will also help with many physical, mental, and social problems that are brought about.
Despite that, these conditions affect more people than we know. Be of service to those with these conditions by understanding first aid principles. These are easily learned through CPRFA’s various courses that include a first aid course, a CPR refresher course, and an advance first aid course among others. This puts you in a position to help them if the need arises.
