abstract: herpes simplex encephalitis (hse) is a life threatening outcome of herpes simplex virus (hsv) infection of the central nervous system (cns). hsv accounts for 2-5 percent of all cases of encephalitis. one third of cases occur in those younger than 20 years old and one half in those older than 50 years old. clinical diagnosis is recommended in the encephalopathic, febrile patients with ...

BACKGROUND Despite the discovery of CSF and serum diagnostic autoantibodies in autoimmune encephalitis, there are still very limited CSF biomarkers for diagnostic and monitoring purposes in children with inflammatory or autoimmune brain disease. The cause of encephalitis is unknown in up to a third of encephalitis cohorts, and it is important to differentiate infective from autoimmune encephali...

BACKGROUND Encephalitis rates by etiology and acute-phase outcomes for encephalitis in the 21st century are largely unknown. We sought to evaluate cause-specific rates of encephalitis hospitalizations and predictors of inpatient mortality in the United States. METHODS Using the Nationwide Inpatient Sample (NIS) from 2000 to 2010, a retrospective observational study of 238,567 patients (mean [...

BACKGROUND Herpes simplex virus (HSV) encephalitis is a life-threatening infection of the brain, which has significant physical, cognitive and social consequences for survivors. Despite increasing recognition of the long-term effects of encephalitis, research and policy remains largely focused on its acute management, meaning there is little understanding of the difficulties people face after d...

PURPOSE In people with suspected inflammatory CNS disease, cerebrospinal fluid (CSF) is commonly analyzed. Antibody-associated limbic encephalitis (ab-LE) and anti-NMDAR-encephalitis are recognized as two major syndromes of autoimmune epilepsies. Here, we investigated the diagnostic value of CSF findings in these two entities. METHODS We reviewed patients from our tertiary epilepsy centre wit...

Knut the polar bear of the Berlin Zoological Garden drowned in 2011 following seizures and was diagnosed as having suffered encephalitis of unknown etiology after exhaustive pathogen screening. Using the diagnostic criteria applied to human patients, we demonstrate that Knut's encephalitis is almost identical to anti-NMDA receptor encephalitis which is a severe autoimmune disease representing t...

EEG findings of epidemiologically and serologically confirmed tick-borne encephalitis patients were compared with findings of patients having acute encephalitis of viral or undetermined origins. Tick-borne encephalitis patients had more bilaterally synchronous bursts of slow waves and more focal abnormalities than did controls. Moreover, their EEGs remained mildly pathological, with increased s...

PURPOSE OF REVIEW This review aims to describe new features on the epidemiology of encephalitis world-wide. As this neurological presentation is most frequently related to transmitted viruses, surveillance of encephalitis is of major importance to detect their emergence or re-emergence. RECENT FINDINGS Rabies causes one of the most severe types of encephalitis as it is lethal in all cases, an...

PURPOSE OF REVIEW This review describes the main types of autoimmune encephalitis with special emphasis on those associated with antibodies against neuronal cell surface or synaptic proteins, and the differential diagnosis with infectious encephalitis. RECENT FINDINGS There is a continuous expansion of the number of cell surface or synaptic proteins that are targets of autoimmunity. The most ...

In this report, we present a rare case of anti-Ma2-associated encephalitis concurrent with coronavirus disease 2019 (COVID-19) following breast cancer surgery. The patient exhibited minimal clinical symptoms COVID-19 infection but developed seizures and altered mental status after surgery, leading to diagnosis classic paraneoplastic syndrome. This highlights the possibility neurological syndrom...
