This has been studied mainly in cohorts with relapsing–remitting MS. However, the association between vascular comorbidities (VCM) and clinical disability in secondary progressive MS (SPMS) is less well studied.

VCM (hypertension and hyperlipidaemia) and non-VCM (asthma, hypothyroidism and osteoporosis) were recorded. A comorbidity score was also determined (0, 1, ≥ 2). Physical disability and processing speed were assessed at baseline, 48- and 96 weeks.
