What is a silent stroke?

A silent stroke, also known as a silent cerebral infarction, is a stroke that occurs without any noticeable symptoms.

How common are silent strokes?

Silent strokes are actually quite common. It is estimated that up to 1 in 5 people will have a silent stroke at some point in their lives. However, because they do not cause any noticeable symptoms, many people are not aware that they have had a silent stroke.

What are the risk factors for silent stroke?

The risk factors for silent stroke are the same as the risk factors for stroke in general. These include:

* High blood pressure

* High cholesterol

How are silent strokes diagnosed?

Silent strokes are often diagnosed incidentally, such as when a person has a brain scan for another reason. However, if a person is experiencing any of the symptoms listed above, their doctor may order a brain scan to rule out a silent stroke.

How are silent strokes treated?

There is no specific treatment for silent strokes. However, treating the underlying risk factors for stroke, such as high blood pressure, high cholesterol, and diabetes, can help to reduce the risk of future strokes.

What is the prognosis for silent stroke?

The prognosis for silent stroke depends on the severity of the stroke and the underlying risk factors for stroke. Most people who have silent strokes recover fully. However, some people may experience long-term problems, such as dementia, depression, and difficulty with memory and thinking.
