REPORT FROM ECTRIMS – BARCELONA, SPAIN – OCTOBER 7-10, 2015 – A recent longitudinal study investigated whether MS patients with ongoing disease activity while on treatment had different clinical, radiological and neuropsychological outcomes at one year compared to those with no evidence of disease activity (NEDA), defined as no relapses, no three-month EDSS progression and no new MRI activity (Nygaard et al. PLoS One 2015;10:e0135974; free full text at www.ncbi.nlm.nih.gov/pmc/articles/PMC4539191/pdf/pone.0135974.pdf).
Overall, 46% of treated MS patients had evidence of disease activity and demonstrated EDSS progression (+0.4 points). In contrast, NEDA patients showed a slight improvement in EDSS scores (-0.3 points), which may be due to an absence of relapse-related short-term disability. Cognitive function was stable in both groups but patients with disease activity had a significantly higher rate of subcortical grey-matter (GM) atrophy compared to healthy controls. Read More
