High blood pressure causes dementia proves research

London: A new study in Cardiovascular Research, published by Oxford University Press, indicates that patients with high blood pressure are at a higher risk of developing dementia. This research also shows (for the first time) that an MRI can be used to detect very early signs of neurological damage in people with high blood pressure before any symptoms of dementia occur.

What is dementia?

Dementia is a term used to describe symptoms such as memory loss, confusion, and problems with speaking and understanding. Dementia is usually progressive, meaning that symptoms get worse over time.

Vascular dementia is the second most common cause of dementia after Alzheimer’s disease. Many people with Alzheimer’s disease are also thought to have some degree of vascular dementia.

What are the effects of vascular dementia?

The effects of vascular dementia depend on which parts of the brain are affected. Most commonly, people will have difficulty with concentrating or remembering things. Others will have difficulty with speaking or communication.

People with vascular dementia can also have difficulties moving around. Some people may be physically disabled or have problems with coordination.

Can vascular dementia be treated?

There is no cure for vascular dementia, but treatment can slow the speed with which symptoms progress. This is usually done by treating the original cause of the damage to the brain. For example, if the damage was caused by a stroke due to high blood pressure, then treatment will focus on preventing any further strokes.

There is some evidence to suggest that drugs used to treat Alzheimer’s disease can help some people with vascular dementia. However, this may be because many people with vascular dementia also have Alzheimer’s disease.

What can cause vascular dementia?

Since vascular dementia is caused by problems with the blood system that supplies the brain, any condition or lifestyle choice that weakens or blocks our blood vessels can cause it. For example, diabetes, high cholesterol and heart problems (such as irregular heart beats) can all cause vascular dementia.

How you can best avoid developing vascular dementia

Adopting a healthy lifestyle will help to slow the build up of damage to your blood vessels and will reduce your risk of developing vascular dementia. Also, if you have a condition that may damage your blood vessels (such as diabetes, high cholesterol and heart problems) it is important to get them under control.

How can one lower the risk of vascular dementia?

Having high blood pressure is a risk factor for vascular dementia. If you can lower your blood pressure through lifestyle changes and medicines, you can reduce your risk.

Vascular dementia is most commonly caused by the effects of a stroke. You can lower your risk of a stroke by keeping your blood pressure and cholesterol levels down.

If you smoke, if you have an unhealthy diet, or if you are overweight or not very active, you should think about changing to a more healthy lifestyle. This will help lower your blood pressure and lower your risk of developing dementia.
