Overview
Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system, typically triggered by infections or vaccinations, characterized by multifocal lesions in the brain and spinal cord leading to neurological deficits 1.Diagnosis
Clinical Presentation: Multifocal neurological deficits, often following an infectious trigger 1.
Imaging: MRI showing multifocal white matter lesions; CT may reveal hypodense areas in cerebral white matter 1.
CSF Analysis: Elevated protein levels and mild pleocytosis may be observed, though not always present 1.
Differential Diagnosis: Distinguish from multiple sclerosis, viral encephalitis, and other demyelinating conditions 1.Management
First-Line Treatment: High-dose intravenous corticosteroids (e.g., methylprednisolone) to reduce inflammation 1.
Duration: Typically administered for 3-5 days 1.
Adjunctive Therapy: Plasma exchange or intravenous immunoglobulin (IVIG) may be considered in refractory cases, though evidence is limited 1.Special Populations
Pediatrics: Common in children; effective response to steroids observed in a 5-year-old patient 1.
Comorbidities: No specific management adjustments noted in the provided abstracts 1.Key Recommendations
Initiate high-dose intravenous corticosteroids for confirmed ADEM diagnosis to reduce neurological symptoms and improve outcomes (Evidence: Strong 1).
Monitor response closely; consider adjunctive therapies like IVIG or plasma exchange in cases refractory to corticosteroids (Evidence: Moderate 1).
Tailor management closely in pediatric patients, as they often respond well to standard steroid therapy 1.References
