Overview of Demyelinating Disorders

Acute Disseminated Encephalomyelitis

Acute disseminated encephalomyelitis (ADEM) occurs due to widespread inflammation that affects the brain and spinal cord. This can damage myelin and lead to early symptoms such as:

Fever
Fatigue
Headache
Nausea or vomiting

More complications could be vision problems, weakness, and issues with coordination and movement. Severe cases of ADEM can be life threatening, leading to seizures or coma.

The onset of ADEM typically follows a bacterial or viral infection. Less commonly, it can occur following some childhood vaccines. However, some research suggests that the condition is only likely to occur 1.16 times per 1 million vaccine doses.
