Infections of the meninges (meningitis) and the brain (encephalitis) needs to be identified and
managed promptly in order to prevent associated morbidity and mortality. Symptoms and signs of raised
intracranial pressure are frequently the initial features of meningitis caused by bacterial or viral infections.
Encephalitis is more frequently caused by viral infections with features that include seizures, personality
change, decreased consciousness, and focal neurological manifestations. As the infection progress, mixed
features are frequently encountered (meningoencephalitis). In this chapter, an updated overview of
meningitis and encephalitis in infants and children is presented.
