Aseptic meningitis

Aseptic meningitis occurs when there are signs of meningitis. However, when a sample of brain fluid is taken, bacteria do not grow. This condition is often treatable. In many cases, recovery takes 7–10 days.
Meningitis happens when the brain's lining becomes inflamed. This lining is called the meninges.'''

Tuberculosis
Fungal infection
Bacterial Meningitis that has not been fully treated
