Dementia is a neurodegenerative disorder that causes memory loss, difficulty in thinking, language, and problem-solving skills.

It is estimated that around 50 million people in the world suffer from dementia, and this number is expected to triple by 2050. With such a widespread increase, researchers across the world are trying to find the underlying causes and possible treatments for dementia.

In recent years, studies have suggested that arterial stiffness could be linked to an increased risk of dementia. Arteries are blood vessels that carry oxygenated blood from the heart to different parts of the body.

Arterial stiffness is a condition where the walls of the arteries become less elastic. This can result in decreased blood flow to different parts of the body, including the brain, leading to cognitive impairments and an increased risk of developing dementia.

What Causes Arterial Stiffness?

Several factors can lead to arterial stiffness, including age, high blood pressure, smoking, and high levels of LDL cholesterol. As people age, their arteries lose elasticity, making them more prone to stiffness.

This condition can also be caused by the buildup of plaque, which narrows the arteries and reduces blood flow.

How is Arterial Stiffness Linked to Dementia?

Studies have shown that people with arterial stiffness have a higher risk of developing cognitive impairments and dementia.

Arterial stiffness affects blood flow to the brain, which deprives the brain cells of oxygen and nutrients, leading to brain damage.

Moreover, arterial stiffness can also cause microbleeds in the brain, leading to inflammation and a buildup of amyloid plaques.

Amyloid plaques are sticky deposits of a protein called amyloid-beta that accumulate in the brain and disrupt the normal functioning of brain cells, leading to cognitive impairments and dementia.

What Can You Do to Prevent Arterial Stiffness?

While arterial stiffness is a natural process that occurs with age, there are several ways to prevent or reduce its effects. The following lifestyle changes can help to prevent or slow down arterial stiffness:.

Quit smoking: Smoking is a major contributor to arterial stiffness, and quitting smoking can be an excellent way to reduce your risk.
Eat a healthy diet: Aim to consume whole foods like fruits, vegetables, lean proteins, and whole grains. Avoid processed foods and foods high in saturated and trans fats.
Exercise regularly: Exercise is an excellent way to maintain healthy arteries. Aim to do at least 150 minutes of moderate-intensity exercise like brisk walking or cycling per week.
Maintain a healthy weight: Being overweight or obese can increase the risk of arterial stiffness. Losing weight can help to reduce this risk.
Manage stress: High levels of stress can contribute to arterial stiffness. Managing stress through activities like meditation, yoga, or deep breathing can be beneficial.
Monitor your blood pressure and cholesterol levels: High blood pressure and cholesterol can contribute to arterial stiffness. Regular monitoring and treatment can be an excellent way to reduce this risk.

The Bottom Line

Arterial stiffness is a common condition that occurs with age and is linked to an increased risk of cognitive impairments and dementia.

While it may not be possible to completely prevent arterial stiffness, taking steps to reduce your risk can be beneficial, including exercise, eating a healthy diet, quitting smoking, and regular monitoring of blood pressure and cholesterol levels.
