World Encephalitis Day 2019

Did you know?

Autoimmune encephalitis (AE) is a newly discovered disease in which the body’s immune system mistakenly attacks healthy brain cells, leading to inflammation of the brain. This inflammation causes various neurologic and/or psychiatric symptoms and makes the brain not function as it should.

There are no specific symptoms that alone make the diagnosis of AE. The hallmark of AE is the rapid onset of a combination of distinct symptoms, such as:

Decreased level of consciousness, seizures, psychosis, severe anxiety, distorted vision, loss of balance, involuntary movements, vision changes, weakness or numbness of part of the body, loss of language, memory difficulties, loss of inhibition, insomnia, cognitive impairment, paranoid thoughts, and hallucinations.

More about AE

  • AE targets children and aduts of all ages. Each year 4,000 people are diagnosed with AE in the US and 90,000 people worldwide. Experts believe this number to be an underestimate due misdiagnosis or no diagnosis at all for many.
  • AE is hard to diagnose. Different symptoms may appear at different times and at different levels of intensity making this disease to mimic other (psychiatric) disorders.
  • Early diagnosis and aggressive treatment greatly improves outcomes. Delayed diagnosis and treatment can lead to permanent brain injury and loss of life.
  • Testing is required for signs of inflammation and auto-antibody production: brain imaging MRI, spinal tap, EEG and blood work.
  • AE patients may benefit from treatment by a team of physicians that may include neurologists, rheumatologists,psychiatrists, immunologists and others.
