[Neuroborreliosis in North Jutland].

Introduction: Infection with Borrelia sp. is common in Denmark, and dissemination to the central nervous system (neuroborreliosis) may develop in a minority of cases with varying symptoms. We here present a population-based review of neuroborreliosis in Northern Denmark.

Neuroborreliosis recurrence: reinfection or relapse?

We report the case of a 47-y-old female with documented neuroborreliosis, who had a complete recovery after 10 d of intravenous high-dose penicillin followed after 9 months by a new episode of documented neuroborreliosis. The case probably represents a rare case of true reinfection rather than relapse.
