Background

The prevalence of pediatric-onset multiple sclerosis (MS) in the United States is unknown.

Objective

In a large cohort of MS patients, we sought to identify the proportion with first symptom-onset below the age of 18 years, and to compare their demographic and disease characteristics to a typical adult-onset MS population.

Methods

Patients seen at the Partners Multiple Sclerosis Center, Brigham and Women’s Hospital, Boston, Massachusetts, with clinical histories and characteristics of first symptoms recorded in an electronic database, were included in this study.

Results

We found that 3.06% of patients with a recorded MS history experienced a first attack under the age of 18 years of age compared to 30.83% of patients who experienced first symptoms between the ages of 25–35 years. Gender proportions were similar in both groups, with the exception of a lower female preponderance in pre-pubertal-onset patients. There was a higher proportion of non-Caucasians in the younger cohort. Localization of first symptoms was similar in the two groups.

Conclusion

About 3% of MS patients experience their first symptom prior to the age of 18 years. Standardized follow-up is required after a first demyelinating attack in childhood, which may lead to earlier diagnosis and treatment of pediatric-onset MS.
