Shingles and Stroke Risk

 

An interesting new study demonstrated a link between the shingles virus and stroke risk.  Shingles is a painful rash that can develop from the varicella zoster virus (VZV).  VZV is the same virus that causes chicken pox in children.  Following infection with chicken pox as a child, the varicella virus lies dormant in the nerve roots.  The virus can then become reactivated later in life and result in a painful rash on one side of the body.  This rash occurs most often in older patients but can occur in patients of any age, especially following periods of stress.

 

A recent study found people who developed shingles between the ages of 18 and 40 were more likely to have a stroke, warning stroke, or heart attack in their lifetime.  Researchers also found an increased incidence of stroke in people who developed shingles after forty years old, but the risk was not as great in this age bracket.

 

Scientists have investigated a link between shingles and stroke previously.  Researchers are uncertain the exact mechanism resulting in the increased risk, but believe it is a result of the shingles’ virus inflammatory effects on the circulatory system. 

 

What does this study mean for you?  If you are over 60 years old and have not been vaccinated for shingles, consult with your primary care provider about receiving this vaccine.  Preventing shingles is the number one goal.  However, if you have already developed shingles, it is important to be aware of this risk, and take effort to speak with your healthcare provider about modifying other habits that can increase your stroke risk.  Smoking, high cholesterol, and obesity are all modifiable risk factors that can increase the risk of heart attack and stroke.  Making changes in these areas are vital to improving your cardiovascular health and decreasing your stroke risk.  Make sure you speak with your health care provider before making any changes in diet or exercise, and, of course, consult your skin care provider at the onset of any new rashes.
