Abstract

Objective: Older people with multiple sclerosis have a less active radiological and clinical presentation, but many still attain significant levels of disability; but what drives worsening disability in this group?Methods: We used data from the UK MS Register to characterise demographics and clinica...

We performed a pathology study of a separate MS cohort with a later onset (n=18, mean age of onset 54 years) versus AOMS (n=23, age of onset 30 years).Results: In the Register cohort there were 1608 (9.4%) with LOMS. When compared with AOMS, there was a lower proportion of females, a higher proportion of primary progressive MS, a higher level of disability at diagnosis (median MS impact scale 36.7 v 28.3, p&lt;0.001), and a higher proportion of gait-related initial symptoms.
