[Lyme disease--neuroborreliosis]

Lyme disease is an infective disease caused by Borrelia burgdorferi transmitted by ticks of the Ixodes ricinus. The disease usually has three stages whereas the last, because of domination of neurologic symptomatology is called "neuroborreliosis". This is a case report of a female patient with neuroborreliosis in whom, due to lack of symptoms and signs which characterize the first stage of Lyme disease as well as lack of evidence about the tick, nobody assumed such an etiology. Lyme disease was not confirmed by serologic evaluation until the third stage of the disease occurred. This case points to the conclusion that by differential diagnosis of meningeal syndrome accompanied by maintenance and progredience of neurologic deficit and disorders in mental sphere one should think of the Lyme disease.
