Distinction between acute disseminated encephalomyelitis and acute multiple sclerosis is often clinically difficult. Perivenous demyelination is the pathological hallmark of acute disseminated encephalomyelitis, whereas confluent demyelination is the hallmark of acute multiple sclerosis. We investigated whether perivenous demyelination versus confluent demyelination distinguishes acute dissemin...

Acute disseminated encephalomyelitis is a demyelinating disease, typically occurring in children following a febrile infection or a vaccination. Primary and secondary immune responses contribute to inflammation and subsequent demyelination, but the exact pathogenesis is still unknown. Diagnosis of acute disseminated encephalomyelitis is strongly suggested by temporal relationship between an inf...

Acute Disseminated Encephalomyelitis (ADEM) is a monophasic demyelinating disease most often triggered by infection or immunization, though associations with malignancy and stem cell transplant have been described. We described the case of a four-year-old boy with new-onset neurological symptoms associated with ADEM, acute leukemia, and equivocal evidence of Mycoplasma pneumoniae infection. He ...

Acute disseminated encephalomyelitis is an immune-mediated inflammatory demyelinating disorder of the central nervous system. The first-line treatment is usually high-dose intravenous methylprednisolone. Intravenous immunoglobulin and plasmapheresis have also shown to be beneficial. Immunosuppressive agents like cyclophosphamide have been used in adults with fulminant acute disseminated encepha...

Acute disseminated encephalomyelitis (ADEM) is a monophasic inflammatory disorder of the central nervous system (CNS). Unlike viral encephalitis, microorganisms do not invade the CNS. Instead, ADEM is a postinfectious disease mediated by auto-reactive cells or molecules. Clinical characteristics of ADEM are consistent with disseminated involvement of the CNS, including encephalopathy and pyrami...

Acute disseminated encephalomyelitis (ADEM) is an acute demyelinating disorder of the central nervous system, and is characterised by multifocal white matter involvement. Diffuse neurological signs along with multifocal lesions in brain and spinal cord characterise the disease. Possibly, a T cell mediated autoimmune response to myelin basic protein, triggered by an infection or vaccination, und...

Background: Acute disseminated encephalomyelitis (ADEM), which occurs spontaneously or after systemic viral infection and vaccination mostly affects children. This study aims at describing the epidemiologic, clinical, neuroimaging, laboratory features, treatment and outcome in children who diagnosed as having ADEM and admitted in a referral center in Tehran. Methods: This descriptive prospectiv...

Acute disseminated encephalomyelitis (ADEM) is an uncommon inflammatory demyelinating disease of the central nervous system. The true incidence of the disease in India is undetermined and is likely to be more frequent than reported, as the common antecedent events, exanthematous fevers and Semple antirabies vaccination, which predispose to ADEM, are still prevalent. The existing evidence sugges...

The advent of magnetic resonance imaging (MRI) has contributed to increase the interest and awareness in childhood white matter disorders. Pediatric inflammatory demyelinating diseases of the central nervous system (CNS) are clinically heterogeneous with respect to their mode of presentation, clinical severity, rate of progression, and prognosis. Acute disseminated encephalomyelitis (ADEM) is a...
