Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [2] The word is from Ancient Greek ἐγκέφαλος, enképhalos 'brain', [37] composed of ἐν, en, 'in' and κεφαλή, kephalé, 'head', and the medical suffix -itis 'inflammation'. [38]
'brain'; and the medical suffix -itis, "inflammation"), also known as herpes meningoencephalitis, is a medical condition that simultaneously resembles both meningitis, which is an infection or inflammation of the meninges, and encephalitis, which is an infection or inflammation of the brain tissue.
Infections of the central nervous system (CNS) consist of infections primarily of the brain and spinal cord. They include mostly viral infections, less commonly bacterial infections, fungal infections, prion diseases and protozoan infections. Neonatal meningitis is a particular classification by age.
Meningitis is acute or chronic inflammation of the protective membranes covering the brain and spinal cord, collectively called the meninges. [10] The most common symptoms are fever, intense headache, vomiting and neck stiffness and occasionally photophobia. [1]
Chronic meningitis is a long-lasting inflammation of the membranes lining the brain and spinal cord (known as the meninges). By definition, the duration of signs, symptoms and inflammation in chronic meningitis last longer than 4 weeks. [ 2 ]
Neuroinflammation is widely regarded as chronic, as opposed to acute, inflammation of the central nervous system. [5] Acute inflammation usually follows injury to the central nervous system immediately, and is characterized by inflammatory molecules, endothelial cell activation, platelet deposition, and tissue edema.

That can lead to the brain infection and abscesses that Bragg described. These complications are more likely to develop in kids and teens because of the way the sinuses develop as children get older.
Lymphocytic choriomeningitis is a particular concern in obstetrics, as vertical transmission is known to occur. For immunocompetent mothers, there is no significant threat, but the virus has damaging effects upon the fetus. If infection occurs during the first trimester, LCMV results in an increased risk of spontaneous abortion. [14]
