Medication
The key to treating encephalitis is early detection and treatment. A person with encephalitis requires immediate hospitalization and close monitoring. The goal of treatment is to reduce the swelling in the head and to prevent other related complications. Medications to control the infection, seizures, fever, or other conditions may be used.
Self-care
Intravenous aciclovir is a life-saving treatment in HSV encephalitis and has reduced mortality from above 70% to around 10–20%. 20,21 It is relatively safe, although there is a small risk of renal impairment owing to a crystal nephropathy. 22 Renal function should be monitored; in patients with known renal impairment the dose should be reduced.

Autoimmune Encephalitis is treated with immunotherapy. Immunotherapy slows down the over-excited immune system. By slowing down the immune system it slows down the process the immune system is engaging in, which is creating the foreign antibodies that are attacking healthy brain cells.
How long does it take for autoimmune encephalitis to come back?
Experts in the field do NOT wait for antibody testing to come back. This process can take up to 10 days and time is of the essence. Since a negative antibody test does not rule out autoimmune encephalitis, the clinician treats without delay.

What is the most common cause of encephalitis?
Worldwide, infection of the central nervous system is the commonest cause of acute encephalitis. Herpes simplex virus (HSV), varicella zoster virus (VZV), Epstein-Barr virus (EBV), mumps, measles, and enteroviruses are responsible for most cases of acute viral encephalitis among immunocompetent individuals in the United Kingdom. In a large Finnish study reported recently, VZV was found to be the commonest virus associated with encephalitis as well as meningitis and myelitis, comprising 29% of all confirmed or probable aetiological agents while HSV and enteroviruses accounted for 11% each and influenza A virus 7% of the cases. 1 Tuberculosis, rickettsial diseases, and human African trypanosomiasis are important non-viral causes of meningoencephalitis but will not be covered in this article. Acute disseminated encephalomyelitis (ADEM) and its more severe form, acute haemorrhagic leucoencephalitis (AHLE) represent non-infective central nervous system inflammatory diseases. Non-inflammatory diffuse brain dysfunction is termed encephalopathy; metabolic dysfunction and intoxications are its best examples.
What is nipah virus?
9 This virus was closely related, but not identical, to another animal virus (Hendra virus) that had previously caused disease among horses and three patients in Australia. 37 Nipah virus encephalitis is the first wide scale epizoonotic encephalitis with direct animal-to-human transmission, unlike most other epizoonotic encephalitis (for example, Japanese encephalitis, West Nile virus encephalitis, Eastern equine virus encephalitis), where vectorial transmission is the rule. Over 200 people were affected in Malaysia alone and the cluster outbreak severely disrupted the pig farming industry. The affected pigs died unusually and suddenly. The human illness was characterised by a history of direct contact with pigs in the livestock farm, short incubation period (two weeks), rapidly declining level of consciousness, prominent brain stem dysfunction, and high fatality rates. Distinctive clinical signs included segmental myoclonus, areflexia, hypotonia, and dysautonomia (hypertension and tachycardia). Initial findings in the cerebrospinal fluidwere abnormal in 75% cases, EEG showed diffuse slow waves with focal abnormalities over temporal regions (75%), computed tomograms were normal and magnetic resonance imaging of the brain during the acute phase of illness showed widespread focal lesions in the subcortical and deep white matter. 10
How is ADEM distinguished from infective encephalitis?
ADEM may be distinguished from infective encephalitis by the younger age of the patient, prodromal history of vaccination or infection, absence of fever at the onset of symptoms, and the presence of multifocal neurological signs affecting optic nerves, brain, spinal cord, and peripheral nerve roots.

Is encephalitis a medical emergency?
Acute encephalitis constitutes a medical emergency. In most cases, the presence of focal neurological signs and focal seizures will distinguish encephalitis from encephalopathy. Acute disseminated encephalomyelitis is a non-infective inflammatory encephalitis that may require to be treated with steroids. Acute infective encephalitis is usually viral. Herpes simplex encephalitis (HSE) is the commonest sporadic acute viral encephalitis in the Western world. Magnetic resonance imaging of brain is the investigation of choice in HSE and the diagnosis may be confirmed by the polymerase chain reaction test for the virus in the cerebrospinal fluid. In this article, we review the diagnosis, investigations, and management of acute encephalitis. With few exceptions (for example, aciclovir for HSE), no specific therapy is available for most forms of viral encephalitis. Mortality and morbidity may be high and long term sequelae are known among survivors. The emergence of unusual forms of zoonotic encephalitis has posed an important public health problem. Vaccination and vector control measures are useful preventive strategies in certain arboviral and zoonotic encephalitis. However, we need better antiviral therapy to meet the challenge of acute viral encephalitis more effectively.
Is zoonotic encephalitis a public health problem?
The emergence of unusual forms of zoonotic encephalitis has posed an important public health problem. Vaccination and vector control measures are useful preventive strategies in certain arboviral and zoonotic encephalitis.
