Tuberculous meningitis: A narrative review

Tuberculous meningitis (TBM) is a medical emergency. It is the most devastating manifestation of tuberculosis (TB). The outcome depends on early diagnosis and appropriate treatment. Empirical antituberculous therapy should be started if clinical suspicion is high. All patients should be tested for HIV. The choice of antituberculous drugs is extrapolated from pulmonary TB regimen, and many drugs have poor cerebrospinal fluid penetration. More evidence is required to guide on drug therapy in TBM. Steroids should be used as adjunctive therapy and response may be modulated by host genotype. Active monitoring should be done for complications such as hydrocephalus, hyponatremia, and stroke.
