No regional gray matter atrophy differences between pediatric- and adult-onset relapsing-remitting multiple sclerosis.

Objective: To investigate differences in region-specific gray matter (GM) damage between adults with pediatric-onset (PO) multiple sclerosis (MS) and adult-onset (AO) MS.

Methods: Twenty-four relapsing-remitting (RR) adults with POMS (mean age = 35 years, mean disease duration = 18.4 years) were compared to 23 age-matched (AOA, mean age = 33.
