Tuberculous meningitis is distinct from the forms of meningitis because it lasts longer, has a higher mortality rate, and, if left untreated, may result in brain deformity. Lastly, Cryptococcal meningitis is a fungal infection caused by a fungus found in soil worldwide. Patients with risk factors for this form of meningitis include those with AIDS, diabetes and leukemia.
