Varicella zoster virus (VZV) infects >95 % of the world population. Typically,
varicella (chickenpox) results from primary infection. The virus then becomes
latent in ganglionic neurons along the entire neuraxis. In immunocompromised
individuals, VZV reactivates and causes herpes zoster (shingles), pain, and rash
in 1-2 dermatomes. Multiple case reports showed a link between stroke and zoster,
and recent studies have emerged which reveal that VZV infection of the cerebral
arteries directly causes pathological vascular remodeling and stroke (VZV
vasculopathy). In the past few years, several large epidemiological studies in
Taiwan, Denmark, and the U.K. demonstrated that zoster is a risk factor for
stroke and that antiviral therapy may reduce this risk. Herein, the history,
clinical features, and putative mechanisms of VZV vasculopathy, as well as recent
epidemiological studies demonstrating that zoster increases the risk of stroke,
are discussed.
