The relationship between herpes zoster and stroke.
Abstract 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 epide...

Stroke risk higher after shingles, but antiviral drugs may provide protection
(Infectious Diseases Society of America) Patients' risk of stroke significantly increased following the first signs of shingles, but antiviral drugs appeared to offer some protection, according to a new study in Clinical Infectious Diseases, now available online. People with shingles, an often painful skin rash caused by the same virus that causes chickenpox, had a higher stroke risk in the first six months after shingles symptoms appeared; this risk was particularly increased in patients with a rash near their eyes, the study found.

VZV reactivation: A comorbid connection?
Varicella zoster virus (VZV) is a neurotropic alphaherpesvirus. Primary infection usually results in varicella (chickenpox), after which the virus becomes latent in ganglionic neurons along the entire neuraxis. As the VZV-specific cell-mediated immunity to VZV declines with age and immunosuppression, VZV can reactivate, resulting in zoster (shingles). Furthermore, zoster is often complicated by multiple neurological and ocular disorders. Among the most serious is VZV vasculopathy where the productive virus infection of cerebral arteries leads to stroke. The diverse manifestations, laboratory features, pathogenesis and trea...

Shingles rash linked to higher risk of stroke
Shingles, the nerve rash in adulthood caused by reactivation of the chickenpox virus, is an independent risk factor for stroke and other blood clot events, the largest study to confirm the association has found.Publishing their findings in Neurology, the journal of the American Academy of Neurology, the researchers found that shingles was a risk factor for stroke and transient ischemic attack (TIA, a mini-stroke).The increased risk was independent of other factors known to raise the chances of vascular events, including obesity, smoking and high cholesterol.

Unusual Trigeminal Autonomic Pain Heralding Hemichorea due to Zoster Sine Herpete Vasculopathy
Conclusions: We suggest that the recognition of this prodromal manifestation, which can be interpreted as a zoster sine herpete, could provide clinicians an extremely useful time window to start promptly with a prophylactic treatment.
