[ALS-like sequelae in chronic neuroborreliosis]

CSF investigation in a 61-year old female patient with clinical picture of motoneuron disease gave evidence for chronic infection with Borrelia burgdorferi. Improvement of clinical and CSF findings could be observed after antibiotic therapy. The diagnosis of amyotrophic lateral sclerosis which was initially suspected had to be revised and the disorder was interpreted as chronic neuroborreliosis.
