Abstract:
The authors report 6 children with the diagnosis of acute disseminated encephalomyelitis. Diagnosis was based on clinical and radiological findings. The most common presenting symptoms were fever and disturbed consciousness, followed by cranial nerve abnormalities and pyramidal signs. Brain MRI showed hyperintense signals on T2-weighted images, most commonly in the subcortical and periventricular white matter, brainstem, basal ganglia and thalamus. The lesions were bilateral, asymmetrical and highly variable in size and number. A preceding infection was present in 3 of 6 children. Early high-dose corticosteroids were given to all the patients. All patients recovered clinically. Follow-up ranged from 10 months to 2 years. No relapses were observed during this period. Early high-dose steroid therapy seems to be an effective treatment in acute disseminated encephalomyelitis.
Insights
Early high-dose corticosteroids effectively treated acute disseminated encephalomyelitis (ADEM) in children, leading to full recovery without relapses. This study highlights ADEM
Area of Science:
- Pediatric Neurology
- Neuroimmunology
- Infectious Diseases
Background:
- Acute disseminated encephalomyelitis (ADEM) is a rare, immune-mediated demyelinating disease affecting the central nervous system.
- ADEM often follows an infection or vaccination, presenting with diverse neurological symptoms.
Purpose of the Study:
- To describe the clinical and radiological features of ADEM in children.
- To evaluate the efficacy of early high-dose corticosteroid treatment in pediatric ADEM.
Main Methods:
- Retrospective case series of 6 children diagnosed with ADEM based on clinical and MRI findings.
- Review of presenting symptoms, neurological examination, brain MRI characteristics, preceding infections, treatment, and clinical outcomes.
Main Results:
- Common symptoms included fever, disturbed consciousness, cranial nerve palsies, and pyramidal signs.
- Brain MRI revealed bilateral, asymmetrical white matter lesions in T2-weighted images.
- Three out of six children had a preceding infection; all received early high-dose corticosteroids and recovered fully with no relapses during follow-up (10 months to 2 years).
Conclusions:
- Early high-dose corticosteroid therapy appears to be an effective treatment for pediatric ADEM.
- Prompt diagnosis and treatment are crucial for favorable outcomes in ADEM.
