[Chronic Borrelia Disease of the Central Nervous System]

A few years ago meningoradiculitis Garin-Bujadoux-Bannwarth (Bannwarth's syndrome) was discovered to be a neurological manifestation of Lyme disease transmitted by tick-bites and caused by Ixodes-ricinus-spirochaete (borrelia burgdorferi). Not enough attention is given to the fact that more serious and chronic disease of the central nervous system may be entailed. Two cases are reported in which detection of the borrelian-antibodies corroborated the diagnosis. After parenteral treatment with penicillin there was a drastic improvement in both patients.
