Herpes zoster, commonly known as shingles, is a viral infection caused by the varicella-zoster virus, which is also responsible for causing chickenpox.

Shingles typically affects adults over the age of 50 and manifests as a painful rash that usually appears on one side of the body. In addition to causing physical discomfort, researchers have now found that herpes zoster is associated with a higher incidence of stroke.

Understanding the link between herpes zoster and stroke

According to a study published in the Annals of Neurology in 2018, individuals who develop shingles have a 30% higher risk of stroke within the first six months after their diagnosis compared to those who have not had shingles.

The study was conducted using data from over 6.3 million individuals, making it one of the largest studies to explore the link between herpes zoster and stroke. The researchers found that the increased risk of stroke was most prominent in individuals under the age of 40 and those with pre-existing risk factors for stroke such as diabetes, hypertension, and high cholesterol.

One possible explanation for the link between herpes zoster and stroke is inflammation. Herpes zoster causes inflammation in the body, which can affect blood vessels and lead to the development of blood clots that can cause a stroke.

Additionally, the pain and discomfort associated with shingles may lead to decreased physical activity and an increased risk of developing other health issues, such as obesity and hypertension, which are also risk factors for stroke.

Preventing the risk of stroke associated with herpes zoster

There are several strategies that individuals with herpes zoster can take to reduce their risk of stroke.

First and foremost, it is important to follow the treatment plan recommended by your healthcare provider to manage the symptoms of shingles and prevent complications. This may include antiviral medications, pain relievers, and topical creams.

Individuals with shingles should also take steps to stay physically active, manage their stress levels, and maintain a healthy diet to reduce their risk of developing other health issues that could increase the risk of stroke.

It is also important for individuals with herpes zoster to work closely with their healthcare provider to manage any pre-existing risk factors for stroke. This may include taking medications to manage hypertension, diabetes, and high cholesterol.

Individuals who smoke should also make an effort to quit, as smoking is a major risk factor for stroke as well as other serious health issues.

Conclusion

Herpes zoster is a viral infection that is associated with a higher incidence of stroke, particularly in individuals under the age of 40 and those with pre-existing risk factors for stroke.

While the exact mechanism behind this link is not fully understood, inflammation and decreased physical activity may play a role. Individuals with herpes zoster can take steps to reduce their risk of stroke by following their healthcare provider’s treatment plan, staying physically active, managing stress levels, and maintaining a healthy diet.

Managing pre-existing risk factors for stroke is also essential in reducing the overall risk.
