If more severe neurologic manifestations occur in early systemic Lyme disease, management may require what?

• A. Shorter duration of oral antibiotics
• B. Longer duration of antibiotics given IV
• C. Only topical therapy
• D. No antibiotics

Answer: (B)

When Lyme disease affects the nervous system in the early disseminated phase, it signals involvement of the CNS or meninges. Oral antibiotics may not reach adequate levels in the CSF to fully eradicate Borrelia in this setting. Therefore, treatment should use intravenous antibiotics to achieve reliable CNS penetration and a sufficient duration of therapy. Typically, this is 14–28 days of IV therapy (for example, ceftriaxone 2 g IV daily or IV penicillin G), with the exact length guided by the clinical response and specific neurologic manifestations. Shorter or oral regimens are generally insufficient for more significant neurologic involvement, and “no antibiotics” or topical therapy would be inappropriate.
