Appropriate, critical application of evidence-based diagnostic criteria enables both a clear definition of what constitutes neuroborreliosis—nervous system infection with Borrelia burgdorferi sensu stricto in the US, B garinii and less commonly B. afzelii and other species in Europe—and recognition that this disorder is quite similar in Europe and the US. Most commonly evidenced by lymphocytic meningitis and/or multifocal inflammation of the peripheral (common; cranial neuropathy, radiculopathy, mononeuropathy multiplex) or central (rare) nervous system, it is readily diagnosed and highly antibiotic responsive. Encephalopathy—altered cognition or memory—can occur as part of the systemic infection and inflammatory state, but is not evidence of neuroborreliosis. Post treatment Lyme disease syndrome—persistent neurobehavioral symptoms 6 months or more after usually curative antibiotic treatment—if real and not simply an example of anchoring bias—is unrelated to neuroborreliosis. The pathophysiology of neuroborreliosis remains unclear, but appears to involve both a requirement for viable micro-organisms and significant immune amplification.
