While shingles itself is not directly associated with causing a stroke, there is evidence to suggest that having shingles may increase the risk of stroke in some people.
Shingles is caused by the varicella-zoster virus, which is the same virus that causes chickenpox. After a person has chickenpox, the virus can remain dormant in the nervous system for many years before reactivating as shingles.
Studies have found that having shingles may increase the risk of stroke in certain populations, such as older adults and those with other risk factors for stroke. One theory is that the inflammation caused by shingles may contribute to the development of cardiovascular disease, including stroke.
It’s important to note, however, that the risk of stroke associated with shingles is generally small, and most people who have shingles do not experience any stroke-related complications. If you have concerns about your risk of stroke, it’s always a good idea to talk to your doctor.
