Answer

Encephalitis presents as diffuse or focal neuropsychological dysfunction. Although it primarily involves the brain, it often involves the meninges as well (meningoencephalitis). From an epidemiologic and pathophysiologic perspective, encephalitis is distinct from meningitis, though on clinical evaluation both can be present, with signs and symptoms of meningeal inflammation. It is also distinct from cerebritis.
