Postinfectious Encephalitis


  • SUMMARY: Encephalitis and postinfectious encephalitis present as neurologic emergencies requiring prompt diagnosis and initiation of treatment.[ncbi.nlm.nih.gov]
  • More than 70 acute pediatric presentations are covered in a signs and symptoms section designed with side tabs for easy access.[books.google.com]
  • This combination is also clearly seen in the present study, which identified three cases where both perivenous and confluent demyelination were present side-by-side in the biopsy or autopsy specimens.[doi.org]
  • Poor functional outcome was related to initial high Expanded Disability Status Scale score and absence of fever.[doi.org]
  • The symptoms of ADEM appear rapidly, beginning with encephalitis-like symptoms such as fever, fatigue, headache, nausea and vomiting, and in the most severe cases, seizures and coma.[ninds.nih.gov]
  • However, ADEM usually has symptoms of encephalitis (such as fever or coma), which are usually not present in MS.[rarediseases.info.nih.gov]
  • 2 Signs and symptoms of measles-induced encephalitis Signs and symptoms of measles-induced encephalitis Measles symptoms Encephalitis symptoms Fever Fever Morbilliform rash Headache Cough Altered level of consciousness Coryza Behavioral disturbances[dx.doi.org]
  • As a result of this gait impairment, falling is a concern in patients with ataxia.[en.wikipedia.org]
  • Most forms of LE fall into two main categories: infectious encephalitis and autoimmune encephalitis.[encephalitis.info]
  • This is partly due to the fall in measles cases as a result of the MMR vaccine. PML is also quite rare. It mainly only affects people with a severely weakened immune system due to factors such as having an end-stage HIV infection (AIDS).[hse.ie]
  • These infections may be Epidemic (eg, due to arbovirus, echovirus, coxsackievirus, or poliovirus [in some underdeveloped countries]) Mosquito-borne arboviral encephalitides infect people during the spring, summer, and early fall when the weather is warm[merckmanuals.com]
  • The most common fall into 3 groups: 1) Herpes Viruses – HSV-1 (and HSV-2 to a much lesser extent), VZV, CMV, EBV, HHV-6.[errolozdalga.com]
Buffalo Hump
  • Metabolic: Corticosteroids cause a movement of body fat to the face and torso, resulting in " moon face ", "buffalo hump", and "pot belly" or "beer belly", and cause movement of body fat away from the limbs.[en.wikipedia.org]
  • This edition's highlights include new chapters on palpitations, cystic fibrosis, travel related emergencies, and ultrasound and a new appendix on practice pathways.[books.google.com]
Facial Swelling
  • Some were felt to be vasovagal reactions, and some included slight facial swelling or pallor. It was unclear whether any of these reactions were anaphylactic.[nap.edu]
  • This can lead to changes in a person's thinking and behaviour, such as: delusions - believing things that are obviously untrue paranoia - a belief that people are 'out to get you' and are actively plotting against you Some cases of autoimmune encephalitis[hse.ie]
  • During the entire course, the patient showed no evidence of auditory hallucinations, delusions or other symptoms suggestive of schizophrenia. Overall, his presentation remained stable during follow-up. The timeline is shown in Fig. 3.[springerplus.springeropen.com]

  • No reports of meningitis occurred more than 14 days after vaccination. Eight (62%) were primary vaccinees.[doi.org]
  • ASEPTIC MENINGITIS Clinical Description Aseptic meningitis is defined as an inflammation of the meninges associated with pleocytosis of the CSF.[nap.edu]
  • However, there can be overlap of laboratory values for viral and bacterial encephalitis, or meningitis (see Table I. Cerebrospinal fluid findings in meningitis).[infectiousdiseaseadvisor.com]

Cerebellar Sign
  • Multifocal neurological deficits consisting of combinations of pyramidal and cerebellar signs are very common, as are cranial neuropathies, including bilateral optic neuritis, encountered more frequently in ADEM than MS (table 2).[jnnp.bmj.com]


  • Other features include a Chief Complaints section addressing the workup and treatment of 50 signs and symptoms, plus a medication index, syndromes glossary, surgical glossary, laboratory values, and tables all for quick reference saving you time and helping[books.google.com]
  • Workup should include a thorough history and physical exam to determine if the clinical course could be consistent with AE.[aealliance.org]
  • The routine diagnostic workup of M. pneumoniae encephalitis should therefore aim for the detection of M. pneumoniae antibodies in both CSF and serum, in addition to M. pneumoniae PCR in CSF.[journals.plos.org]

  • The aim of this review was to describe available data concerning diagnosis and treatment of postinfectious encephalitis, focusing on acute disseminated encephalomyelitis (ADEM) and acute hemorrhagic leukoencephalitis (AHLE).[ncbi.nlm.nih.gov]
  • Treatment Treatment for ADEM is targeted at suppressing inflammation in the brain using anti-inflammatory drugs.[ninds.nih.gov]


  • RECENT FINDINGS: The increasing availability of brain MRI studies has allowed a better delineation of diagnosis and prognosis of postinfectious central nervous system disorders.[ncbi.nlm.nih.gov]
  • Prognosis Corticosteroid therapy typically helps hasten recovery from most ADEM symptoms. The long-term prognosis for individuals with ADEM is generally favorable.[ninds.nih.gov]
  • Prognosis is also related to the antecedent factors.[neurologyindia.com]
