Parent Registry: SCF-RDOS Neuroimmunology & Demyelinating Disorders Registry

I. Definition

ACUTE DISSEMINATED ENCEPHALOMYELITIS (ADEM) is an acute, monophasic, immune-mediated inflammatory demyelinating disorder of the central nervous system characterized by widespread inflammatory injury affecting the brain, spinal cord, and occasionally the optic nerves.

ADEM most commonly occurs following infection or vaccination and is characterized by multifocal neurological deficits accompanied by encephalopathy.

Within the SCF framework, ADEM is classified as an Acute Neuroimmune Dysregulation Syndrome resulting from transient immune-circuit desynchronization leading to inflammatory myelin injury and neural network dysfunction.
