[Acute Disseminated Encephalomyelitis].

Absrtract Acute disseminated encephalomyelitis (ADEM) is an immune-mediated inflammatory demyelinating disorder of the central nervous system that predominantly affects the pediatric population, and it is characterized by an acute or subacute onset of multifocal neurological symptoms. ADEM is typically a monophasic illness, and the majority of cases are associated with either a preceding infection or vaccination. First-line therapy for the disease is intravenous administration of high-dose methylprednisolone, and the long-term prognosis of ADEM is generally favorable.
