Autoimmune encephalitis (AIE) is a type of encephalitis, and one of the most common causes of noninfectious encephalitis. It can be triggered by tumors , infections , or it may be cryptogenic . The neurological manifestations can be either acute or subacute and usually develop within six weeks.
MRI: Exclusion of differential diagnosis (e.g. cerebrovascular disease). Hyperintensity of affected regions on T2-images is characteristic. Sensitivity 60-84 %. [4] [6] EEG: Exclusion of differential diagnosis. Non-characteristic findings may be found in autoimmune encephalitis. Lumbar puncture: Exclusion of differential diagnosis (e.g ...
Limbic encephalitis is associated with an autoimmune reaction. [1] In non-paraneoplastic limbic encephalitis, this is typically due to infection (commonly herpes simplex virus) or as a systemic autoimmune disorder. [13] Limbic encephalitis associated with cancer or tumors is called paraneoplastic limbic encephalitis. [citation needed]
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'.
Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, [3] first described by Edwin Bickerstaff in 1951. [ 4 ] [ 5 ] It may also affect the peripheral nervous system , and has features in common with both Miller Fisher syndrome and Guillain–Barré syndrome .
Anti-NMDA receptor encephalitis is a type of brain inflammation caused by antibodies. [4] Early symptoms may include fever , headache, and feeling tired. [ 1 ] [ 2 ] This is then typically followed by psychosis which presents with false beliefs (delusions) and seeing or hearing things that others do not see or hear (hallucinations). [ 1 ]
The diagnosis is typically made with magnetic resonance imaging of the brain. The findings most characteristic for PRES are symmetrical hyperintensities on T 2-weighed imaging in the parietal and occipital lobes; this pattern is present in more than half of all cases. [1] [3] FLAIR sequences can be better at showing these abnormalities. [4]
A viral infection may also result in encephalitis triggered by an autoimmune response. One common form of autoimmune encephalitis, anti-NMDA receptor encephalitis, is thought to be commonly initiated by herpes infections resulting in an autoimmune response to the NR1 subunit of the NMDA receptor. Lymphocytic pleocytosis is involved in the ...
