Recurrent meningitis is usually caused by bacteria, viruses or non-infectious conditions. Recurrent viral meningitis One recurrent viral meningitis is usually based on herpes simplex virus type 2 (HSV-2;. Called Mollaret meningitis) Is HSV-2 cause, patients typically have ? 3 episodes of fever, neck stiffness and lymphocytic pleocytosis in Liquor on; each episode takes 2-5 days, then she lies down spontaneously. Patients may also other neurological deficits show (z. B. altered sensorium, seizures, cranial nerve palsies). The cause is treated, if possible. A Mollaret meningitis is usually with acyclovir iv treated. Most patients recover completely. Recurrent bacterial meningitis Acute bacterial meningitis can recur when purchased through an acquired or congenital defect in the skull base or in the spine and this defect has been corrected. If the cause is an injury that meningitis can occur until many years later. If the patients have recurrent bacterial meningitis, the clinician should check such defects carefully. A high-resolution CT may constitute defects in the skull generally. Doctors should check the lower back of the patient to a depression or a tuft of hair, which may have a defect in the spine Show (z. B. spina bifida). Rarely based recurrent bacterial meningitis (typically by Streptococcus pneumoniae or Neisseria meningitidis) to a defect of the complement system. The treatment is the same as that for patients without complementary deficits. Vaccination against S. pneumoniae, N. meningitidis (repeat every 3 years) can reduce the likelihood of infection. Other recurrent meningitis An acute meningitis by NSAIDs or other drugs when the causative drug is used again can recur.
