[Varicella zoster infections and neurologic complications].

We describe three patients who suffered from neurological complications to varicella-zoster virus infections. One had polyradiculoneuritis, another myelitis, and a third suffered from focal encephalitis. These patients were all treated with acyclovir, and showed good recovery within a few days. The diagnosis must be based on clinical characteristics, together with virological and immunological tests. The indications for antiviral treatment are discussed.
