[Acute disseminated encephalomyelitis (ADEM): its diagnostic criteria and therapy].

Acute disseminated encephalomyelitis (ADEM) is an immune-mediated central nervous system disorder in an individual with genetic susceptibility. It is characterized by acute or subacute onset of multifocal neurologic deficits with encephalopathy, often following a viral illness or vaccination. Since ADEM is diverse in its clinical features, the diagnostic criteria of ADEM require the exclusion of other etiologies. In this review, I will explain the diagnostic algorism and criteria, and therapy of ADEM.
