Rasmussen’s encephalitis is neurological disorder of childhood characterized by uni-hemispheric inflammation, intractable focal epilepsy and progressive cognitive and neurological deficits. Currently, the pathogenesis of Rasmussen’s encephalitis is still enigmatic and hemispherectomy is the only effective method to control the seizures associated with Rasmussen’s encephalitis. Recently data ind...

BACKGROUND Limbic encephalitis, an immune-mediated encephalitis, results from inflammation in the medial temporal lobes. The paraneoplastic form is rare in pediatric population, and frequently precedes tumor diagnosis. CASE CHARACTERISTICS A 9-year-old boy receiving chemotherapy for Hodgkin lymphoma, developed headache, temporal lobe seizures, anxiety, hallucinations, short-term memory loss a...

INTRODUCTION Post-infectious encephalitis/encephalopathy is a neurological syndrome that sometimes develops following common viral or bacterial infections. The most common form is acute disseminated encephalomyelitis (ADEM). ADEM is a demyelinating disease of the central nervous system that typically presents as a monophasic disorder associated with multifocal neurologic symptoms and encephalit...

BACKGROUND Pathogenic autoantibodies targeting the recently identified leucine rich glioma inactivated 1 protein and the subunit 1 of the N-methyl-D-aspartate receptor induce autoimmune encephalitis. A comparison of brain metabolic patterns in 18F-fluoro-2-deoxy-d-glucose positron emission tomography of anti-leucine rich glioma inactivated 1 protein and anti-N-methyl-D-aspartate receptor enceph...

Background: Pathogenic autoantibodies targeting the recently identified leucine rich glioma inactivated 1 protein and the subunit 1 of the N-methyl-D-aspartate receptor induce autoimmune encephalitis. A comparison of brain metabolic patterns in F-fluoro-2-deoxy-d-glucose positron emission tomography of anti-leucine rich glioma inactivated 1 protein and anti-N-methyl-D-aspartate receptor encepha...

BACKGROUND Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an immune-mediated syndrome caused by the production of anti-NMDAR receptor antibodies. The syndrome characterised by psychosis, seizures, sleep disorders, hallucinations and short-term memory loss. Ovarian teratoma is the confirmed tumour associated with anti-NMDAR antibodies. The patients with anti-NMDAR encephalitis compli...

OBJECTIVES To review past and present patterns of occurrence of Japanese encephalitis in Hong Kong and across Asia. A better understanding of the disease should facilitate the formulation of an effective strategic plan to prevent a future epidemic. DATA SOURCES Report of local cases, and literature search of MEDLINE up to November 2004. STUDY SELECTION Literature and data related to Japanes...

BACKGROUND Encephalitis has many causes, but for most patients the cause is unknown. We aimed to establish the cause and identify the clinical differences between causes in patients with encephalitis in England. METHODS Patients of all ages and with symptoms suggestive of encephalitis were actively recruited for 2 years (staged start between October, 2005, and November, 2006) from 24 hospital...

Enteroviruses have been reported in encephalitis cases. However, clinical and epidemiological characteristics of enteroviruses in encephalitis are not fully established. We prospectively investigated 204 children with encephalitis over a period of 2 years (2009 to 2010) for enterovirus. Enterovirus was detected in 45 specimens (22.1%); of these, 40 were typed by seminested reverse transcription...

Encephalitis is a devastating illness that commonly causes neurologic disability and has a case fatality rate >5% in the United States. An etiologic agent is identified in <50% of cases, making diagnosis challenging. The Centers for Disease Control and Prevention Emerging Infections Program (EIP) Encephalitis Project established syndromic surveillance for encephalitis in New York, California, a...
