Neuroborreliosis, also known as Lyme neuroborreliosis (LNB), is a disorder of the central nervous system. A neurological manifestation of Lyme disease, neuroborreliosis is caused by a systemic infection of spirochetes of the genus Borrelia. Symptoms of the disease include erythema migrans and flu-like symptoms. The microbiological progression of the disease is similar to that of neurosyphilis, another spirochetal infection.

Neuroborreliosis is often preceded by the typical symptoms of Lyme disease, which include erythema migrans and flu-like symptoms such as fever and muscle aches. Neurologic symptoms of neuroborreliosis include the meningoradiculitis (which is more common in European patients), cranial nerve abnormalities, and altered mental status. Sensory findings may also be present. Rarely, a progressive form of encephalomyelitis may occur. In children, symptoms of neuroborreliosis include headache, sleep disturbance, and symptoms associated with increased intracranial pressure, such as papilledema, can occur. Less common childhood symptoms can include meningitis, myelitis, ataxia, and chorea. Ocular Lyme disease has also been reported, as has neuroborreliosis affecting the spinal cord, but neither of these findings are common.

A number of diseases can produce symptoms similar to those of Lyme neuroborreliosis. They include:

Neuroborreliosis presenting with symptoms consistent with amyotrophic lateral sclerosis has been described.

Diagnosis is determined by clinical examination of visible symptoms. Neuroborreliosis can also be diagnosed serologically to confirm clinical examination via western blot, ELISA, and PCR.

In the US, neuroborreliosis is typically treated with intravenous antibiotics which cross the blood–brain barrier, such as penicillins, ceftriaxone, or cefotaxime. One relatively small randomized controlled trial suggested ceftriaxone was more effective than penicillin in the treatment of neuroborreliosis. Small observational studies suggest ceftriaxone is also effective in children. The recommended duration of treatment is 14 to 28 days.
