Encephalitis is anacuteinflammationof thebrain. Encephalitis withmeningitisis known asmeningoencephalitis. Symptoms includeheadache,fever,confusion,drowsiness, andfatigue. Further symptoms
includeseizuresorconvulsions,tremors,hallucinations,stroke, andmemory problems.

Adult patients with encephalitis present with acute onset of fever, headache, confusion, and sometimes seizures. Younger children or infants may present irritability, poor appetite and fever. Neurological examinations usually reveal a drowsy or confused patient. Stiff neck, due to the irritation of the meninges covering the brain, indicates that the patient has either meningitis or meningoencephalitis.

Viral encephalitis can occur either as a direct effect of an acute infection, or as one of thesequelaeof alatent infection. The most common causes of acute viral encephalitis arerabies virus,HPV infection,poliovirus,measles virus. Other possible viral causes are arbovirus (St. Louis encephalitis, West Nile encephalitis virus), bunyavirus (La Crosse strain), arenavirus (lymphocytic choriomeningitis virus) and reovirus (Colorado tick virus).
It can be caused by abacterialinfection, such as bacterialmeningitis, or may be a complication of a current infectious diseasesyphilis(secondary encephalitis). Certainparasiticorprotozoalinfestations, such astoxoplasmosis,malaria, orprimary amoebic meningoencephalitis, can also cause encephalitis in people withcompromisedimmune systems.Lyme diseaseand/orBartonella henselaemay also cause encephalitis. Other bacterial pathogens, like Mycoplasma and those causing rickettsial disease, cause inflammation of the meninges and consequently encephalitis.
Autoimmune encephalitis signs are catatonia, psychosis, abnormal movements, and autonomic dysregulation. Anti-N-methyl-D-aspartate encephalitis and Rasmussen encephalitis are examples of autoimmune encephalitis; the fact that these are immune mediate changes to the treatment path.
