TL;DR: The predominantly relapsing and often severe disease course and the short median time to second attack support the use of prophylactic long-term treatments in patients with MOG-IgG-positive ON and/or myelitis; however, treatment failure leading to rapid accumulation of disability was noted in many patients as well as flare-ups after steroid withdrawal.
Journal ArticleDOI
MOG-IgG in NMO and related disorders: a multicenter study of 50 patients. Part 1: Frequency, syndrome specificity, influence of disease activity, long-term course, association with AQP4-IgG, and origin.

TL;DR: This is the largest cohort studied for IgG to human full-length MOG by means of an up-to-date CBA and finds MOG-IgG is present in a substantial subset of patients with ON and/or myelitis, but not in classical MS.
Journal ArticleDOI
Large Vessel Occlusion in Acute Stroke.
Lena-Alexandra Beume,Maren Hieber,Christoph P. Kaller,Kai Nitschke,Juergen Bardutzky,Horst Urbach,Cornelius Weiller,Michel Rijntjes +7 more
TL;DR: In this article, the authors proposed that cortical symptoms such as aphasia and neglect are more sensitive indicators for large vessel occlusion and the need of mechanical thrombectomy (MT) in ischemic stroke than motor deficits.
Journal ArticleDOI
Visual neglect after left-hemispheric lesions: a voxel-based lesion–symptom mapping study in 121 acute stroke patients
Lena-Alexandra Beume,Markus Martin,Christoph P. Kaller,Stefan Klöppel,Charlotte S. M. Schmidt,Horst Urbach,Karl Egger,Michel Rijntjes,Cornelius Weiller,Roza M. Umarova +9 more
TL;DR: It is shown that in a remarkable number of patients, the left hemisphere essentially contributes to an intact representation of space and clarifies the impact of the distinct left-hemispheric structures involved in visuospatial processing.
Journal ArticleDOI
Activation of disease during therapy with alemtuzumab in 3 patients with multiple sclerosis.
Thomas Wehrum,Lena-Alexandra Beume,Oliver Stich,Irina Mader,Mathias Mäurer,Adam Czaplinski,Cornelius Weiller,Sebastian Rauer +7 more
TL;DR: All patients showed onset of symptoms 6 months after induction of alemtuzumab, strikingly similar MRI lesion morphology, and unexpected high total B cell count, which may suggest a B-cell-mediated activation of disease.
