We thank both Mitchell et al and Janssens et al for their interest in our article.1 We would like to draw their attention to another recently published paper in Neurology2 on this same cohort and not referenced in this article (submitted at the same time as this manuscript to Archives of Neurology). This describes the levels of impairment, disability, and handicap and adds objective and physician-measured information rather than the subjective patient self-reporting as in this Archives paper.
