Is late-onset myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD) associated with a higher risk of time to first relapse or disability compared with adult-onset MOGAD?In this cohort study of 350 adult patients with MOGAD in South Korea, late onset was not uncommon, accounting for 35% of patients. Late onset was not associated with time to first relapse but was independently associated with a higher risk of moderate disability at last follow-up.These findings suggest that patients with late-onset MOGAD may require closer monitoring and early disability-focused interventions.
