Acute Disseminated Encephalomyelitis in Children: An Updated Review Based on Current Diagnostic Criteria

Area of Science:

• Pediatric Neuroimmunology
• Central Nervous System Inflammatory Disorders

Background:

• Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system.
• Until 2007, uniform diagnostic criteria for ADEM were lacking, hindering consistent research and clinical practice.
• The International Pediatric Multiple Sclerosis Society Group (IPMSSG) established consensus definitions in 2007, updated in 2013, to standardize ADEM diagnosis.

Purpose of the Study:

• To provide a comprehensive review of pediatric ADEM based on the IPMSSG criteria.
• To consolidate current knowledge on ADEM epidemiology, pathophysiology, clinical presentation, diagnosis, management, and prognosis.
• To address the relative scarcity of review articles focusing on IPMSSG-defined pediatric ADEM.

Main Methods:

• Systematic review of scientific literature.
• Focus on studies applying the IPMSSG criteria for ADEM diagnosis.
• Synthesis of information on pediatric ADEM from 2007 onwards.

Main Results:

• Epidemiology: Incidence and risk factors for pediatric ADEM.
• Pathophysiology: Mechanisms underlying ADEM in children.
• Clinical Features: Common and rare presentations of ADEM.
• Diagnosis: Application of IPMSSG criteria, differentiating ADEM from other conditions.
• Management: Current therapeutic strategies and treatment protocols.
• Prognosis: Factors influencing recovery and long-term outcomes in pediatric ADEM.

Conclusions:

• Standardized diagnostic criteria are crucial for advancing pediatric neuroimmunology research and clinical care.
• This review offers up-to-date, translatable information on pediatric ADEM for clinicians and researchers.
• Consistent application of IPMSSG criteria facilitates better understanding and management of ADEM in children.
