[Pediatric multiple sclerosis: is it different from the adult form?]

Area of Science:

• Neurology
• Pediatric Neurology
• Clinical Research

Background:

• Multiple sclerosis (MS) affects children, necessitating a comparison between early onset MS (EOMS) and adult onset MS (AOMS).
• Understanding differences in disease course and severity is crucial for pediatric MS management.

Purpose of the Study:

• To compare the clinical characteristics and disease progression of early onset MS (EOMS) with adult onset MS (AOMS).
• To identify potential differences in symptom presentation and long-term outcomes between pediatric and adult MS patients.

Main Methods:

• A retrospective study analyzed 259 MS cases from 1997-2010, defining EOMS as onset before 18 years.
• Data collected from the EDMUS database included demographics, disease duration, Expanded Disability Status Scale (EDSS), and symptomology.
• Severity scores like the Multiple Sclerosis Severity Score (MSSS) and Progression Index were calculated and compared between EOMS and AOMS groups.

Main Results:

• EOMS represented 11.96% of the studied MS population, with a significantly higher frequency of the relapsing-remitting form (94% vs 79%).
• EOMS patients exhibited lower mean EDSS and MSSS scores, indicating less disability progression.
• Neurological symptoms such as gait disturbances and bladder issues were less frequent in EOMS compared to AOMS. The 10-year mean EDSS score was 1.9 for EOMS versus 4.1 for AOMS.

Conclusions:

• Early onset MS is relatively common and demonstrates slower disability progression compared to adult onset MS.
• Despite slower progression, irreversible disability can be reached at an early age in EOMS patients.
• These findings underscore the importance of early diagnosis and tailored management strategies for pediatric MS.
