The presence and burden of cognitive issues: discordance between the perception of neurologists and people living with multiple sclerosis.

Background And Purpose: Cognitive impairment is a common symptom of multiple sclerosis (MS) and occurs in more than 40% of people living with MS (plwMS). No real-world study has assessed the perception of neurologists and plwMS on cognitive issues.

Methods: Using data from the 2011-2019 Adelphi MS Disease Specific Programme database, this real-world, retrospective, cross-sectional multi-cohort study included people aged ≥18 years with relapsing-remitting MS and secondary progressive MS from the United States, UK and the EU.
