What is Acute Necrotising Encephalopathy?

Acute necrotizing encephalopathy (ANE) is a rare disease characterised by brain damage (encephalopathy) that typically follows an acute febrile (characterised by fever) disease, often viral infections. In the case of ANE, symptoms of viral infection are followed by seizures and altered consciousness, that may rapidly progress to a coma, liver issues, and neurological impairments. The brain damage is often widespread, affecting all regions of the brain.

What Causes ANE?

ANE is caused by a combination of environmental and genetic factors. It typically develops secondary to a viral infection, such as influenza. ANE can be familial (IT appears to have a genetic component, however, a single genetic cause is unknown) or sporadic (random), however, both forms are similar. Most familial cases are caused by mutations in the RANBP2 gene and are known as infection-induced acute encephalopathy 3 (IIAE3). The exact mechanism of ANE is not yet known.

What Are Some Challenges Children With ANE May Face?

  • Impaired motor function and regression (loss) of motor skills (i.e. sitting, standing, walking, reaching, grasping, object manipulation)
  • Impaired communication – expressive (i.e. using) and or receptive (i.e. understanding) language
  • Vision changes
  • Cognitive changes and possible intellectual disability
  • Fatigue
  • Impaired emotional regulation
  • Inattention (lack of concentration; distraction)
  • Possible increased susceptibility to recurrent infection resulting in further episodes

The presenting symptoms and prognosis (expected outcome) vary widely between cases, ranging from mild forms with complete recovery (10%) to severe forms with high mortality (30%). However, most survivors present with neurological impairments.

Skills lost following the infection may be regained, however the loss of brain tissue is permanent.

What Are Some Treatment Options for ANE?

Whilst there is no cure for ANE, early intervention through multidisciplinary treatment is recommended to support regaining or maintaining gross motor, fine motor, feeding, communication, and cognitive skills.

  • Physiotherapy may focus on increasing muscle strength, coordination, and re-teaching lost motor skills.
  • Occupational therapy may target upper limb strength and functional use to support activities of daily living such as dressing.
  • Speech and language pathology may address receptive and expressive language, and may also support feeding difficulties.
