INTRODUCTION: Limbic encephalitis generated by anti-N-methyl D-aspartate (NMDA) receptor antibodies is a severe acute neurological condition that is more prevalent in young females and is associated with an underlying tumour. The appearance of severe initial psychiatric signs and symptoms and the fact that it is accompanied by emotional disorders and severe cognitive impairment make it necessary to reconsider the contributions of neuropsychiatry to the diagnosis, development and treatment of the disease, since these have received little attention from researchers to date...

Epilepsy prevention is one of the great unmet needs in epilepsy. Approximately 15% of all epilepsy is caused by an acute acquired CNS insult such as traumatic brain injury (TBI), stroke or encephalitis. There is a latent period between the insult and epilepsy onset that presents an opportunity to intervene with preventive treatment that is unique in neurology. Yet no phase 3 epilepsy prevention studies, and only 2 phase 2 studies have been initiated in the last 16years. Current prevailing opinion is that the research community is not ready for clinical preventive epilepsy studies, and that animal models should first be refined and biomarkers of epileptogenesis and of epilepsy discovered before clinical studies are embarked upon...

BACKGROUND: Rabies is an important viral zoonosis that causes acute encephalitis and death in mammals. To date, several recombinant vaccines have been developed based on G protein, which is considered to be the main antigen, and these vaccines are used for rabies control in many countries. Most recombinant viruses expressing RABV G protein retain the G gene from attenuated RABV. Not enough is currently known about the protective effect against RABV of a combination of recombinant adenoviruses expressing the G and N proteins of pathogenic street RABV...

BACKGROUND: Herpes simplex virus 1 (HSV-1) infection can result in a life-threatening condition known as herpes simplex encephalitis (HSE). Trafficking patterns by which the virus reaches the central nervous system (CNS) following ocular infection are unresolved. We evaluated early viral dissemination pathways following ocular infection that involve trafficking to the olfactory bulb (OB). Additionally, we have characterized the capacity of HSV-1 to establish latency within OB tissue and profiled the local T lymphocyte response over the course of the acute infection into latency...

Early recognition and prompt specific treatment are crucial factors influencing the outcome of patients with acute encephalitis. The aim of this study was to determine the main causes of acute encephalitis in our population and to find predictors that may lead to specific diagnosis. Adult patients admitted to our hospital with suspected diagnosis of encephalitis in the period 2006-2013 were included. One hundred and five medical records were analyzed. Eighty-two patients with infectious encephalitis were identified (78% of total cases), 53 (65%) men and 29 (35%) women, mean age 47...

The risk of unprovoked seizures in population-based cohorts of cerebral infection survivors is 7-8% in developed countries, rising to considerably higher rates in resource-poor countries. The main risk factors for epilepsy after cerebral infection, besides acute seizures, are infection-associated brain lesions and status epilepticus during the acute phase. Despite the high prevalence of pharmacoresistant epilepsies after cerebral infections, especially in patients with MRI-identifiable lesions, only a small minority undergoes epilepsy surgery...

Herpes simplex virus encephalitis is a common and treatable cause of acute encephalitis in all age groups. Certain radiological features such as temporal parenchymal involvement facilitate the diagnosis. The use of herpes simplex virus polymerase chain reaction has expanded the clinical and imaging spectrum. We report the case of a young patient who presented with a movement disorder and predominant involvement of thalami, brainstem and cerebellum on magnetic resonance imaging, and was diagnosed with herpes simplex virus encephalitis...

The neurologic sequelae post-measles are less common than other complications measles-related and can lead to severe disability or death: primary measles encephalitis (PME), acute post-infectious measles encephalomyelitis (APME), measles inclusion body encephalitis (MIBE), and subacute sclerosing panencephalitis (SSPE). SSPE syndrome can affect people years from the acute measles virus infection, as result of the persistence of defective viral particles in brain cells. Clinical onset typically manifests with progressive intellectual deterioration, behavioral changes, and myoclonic jerks...

Viral encephalitis causes acute inflammation of the brain parenchyma and is a significant cause of human morbidity and mortality. Although Herpes Simplex encephalitis is the most frequent known cause of fatal sporadic encephalitis in humans, an increasingly wide range of viruses and other microbial pathogens are implicated. Up to 60% of cases of presumed viral encephalitis remain unexplained due to the failure of conventional laboratory techniques to detect an infectious agent. High-throughput DNA sequencing technologies have the potential to detect any microbial nucleic acid present in a biological specimen without any prior knowledge of the target sequence...

Viruses are a common cause of central nervous system (CNS) infections with many host, agent, and environmental factors influencing the expression of viral diseases. Viruses can be responsible for CNS disease through a variety of mechanisms including direct infection and replication within the CNS resulting in encephalitis, infection limited to the meninges, or immune-related processes such as acute disseminated encephalomyelitis. Common pathogens including herpes simplex virus, varicella zoster, and enterovirus are responsible for the greatest number of cases in immunocompetent hosts...

Bufavirus (BuV) is a newly-identified parvovirus in the family of Parvoviridae. Metagenomic analysis of fecal samples from children in Burkina Faso with acute diarrhea showed a highly divergent parvovirus, which was named bufavirus (BuV). The global distribution, epidemiology and genetic characteristics of BuVs infections are obscure. It was first discovered as an agent causing gastroenteritis but the association of BuV infections with various clinical presentations mostly remain to be explored. The aims of this study were to investigate probable impact of BuV in central nervous system infections in a region where it was previously reported to cause human infections and to detect enteroviruses (EV) which are reported as a cause of central nervous system infections in our country...

Rabies virus (RABV) causes an acute progressive viral encephalitis. Although currently licensed vaccines have an excellent safety and efficacy record, the development of a safer and more cost-effective vaccine is still being sought. An E1-deleted, replication-defective human adenovirus type 5 (HAd5) vector expressing RABV glycoprotein (HAd5-G) is thought to be a promising candidate vaccine for immune prophylaxis against rabies. Salmonella enterica serovar Typhimurium (S. Typhimurium) flagellin is a well-known immune adjuvant...

Tick-borne encephalitis (TBE) is a viral disease that can have a severe acute clinical course and considerable long-term morbidity. As there is no causal treatment currently available for TBE, vaccination is the only way to combat the disease in endemic areas. The studies presented here were conducted to obtain prospective long-term TBE serum antibody persistence data of subjects up to 10years after the first booster with FSME-IMMUN. This report presents the results of 2 follow-up studies in the same study population of 315 healthy adults...
