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'.
Tick-borne encephalitis vaccine is a vaccine used to prevent tick-borne encephalitis (TBE). [4] The disease is most common in Central and Eastern Europe, and Northern Asia. [4] More than 87% of people who receive the vaccine develop immunity. [5] It is not useful following the bite of an infected tick. [4] It is given by injection into a muscle ...
Infants with encephalitis often have seizures or other abnormal movements. Infants with severe encephalitis may become lethargic and comatose and then die. To make the diagnosis of meningitis or the diagnosis of encephalitis, doctors do a spinal tap (lumbar puncture) to obtain cerebrospinal fluid (CSF) for laboratory analysis in children. [6]
"About one out of 150 of those people that develop signs and symptoms can actually develop a more severe disease, like West Nile encephalitis, where we have the swelling of the brain that could ...
Acute necrotizing encephalopathy (ANE) or sometimes necrotizing encephalitis or infection-induced acute encephalopathy (IIAE) is a rare type of brain disease (encephalopathy) that occurs following a viral infection. [4] Most commonly, it develops secondary to infection with influenza A, influenza B, and the human herpes virus 6. ANE can be ...
It can infect the unborn baby, but more often passes to the baby during childbirth. [4] Onset is typically in the first six weeks after birth. [3] The baby is at greater risk of being affected if the mother contracts HSV in later pregnancy. [2] In such scenarios a prolonged rupture of membranes or childbirth trauma may increase the risk further ...
Rarely, treated individuals can have relapse of infection weeks to months later. There is evidence that aberrant inflammation triggered by herpes simplex can result in granulomatous inflammation in the brain, which responds to steroids. [16] While the herpes virus can be spread, encephalitis itself is not infectious.
For some forms of viral encephalitis, such as Eastern equine encephalitis and Japanese encephalitis, there may be a significant amount of necrosis of nerve cells. Following encephalitis caused by arboviruses, calcification may occur in the CNS, especially among children. Herpes simplex encephalitis tends to produce necrotic lesions in the CNS. [1]
