Journal ArticleDOI
Evidence of axonal damage in the early stages of multiple sclerosis and its relevance to disability.
Nicola De Stefano,Sridar Narayanan,Gordon S. Francis,Rozie Arnaoutelis,Maria Carmela Tartaglia,Jack P. Antel,Paul M. Matthews,Douglas L. Arnold +7 more
TL;DR: Cerebral axonal damage begins and contributes to disability from the earliest stages of the disease, even before significant disability (measured using the Expanded Disability Status Scale [EDSS]) was evident clinically.
Journal ArticleDOI
Axonal metabolic recovery in multiple sclerosis patients treated with interferon β-1b
Sridar Narayanan,Nicola De Stefano,Gordon S. Francis,Rozie Arnaoutelis,Zografos Caramanos,D. Louis Collins,Daniel Pelletier,Barry G. W. Arnason,Jack P. Antel,Douglas L. Arnold +9 more
TL;DR: The data suggest that, in addition to losing axons, patients with chronic multiple sclerosis suffer from chronic, sublethal axonal injury that is at least partially reversible with interferon β–1b therapy.
Journal ArticleDOI
Choline is increased in pre-lesional normal appearing white matter in multiple sclerosis
Maria Carmela Tartaglia,Sridar Narayanan,N. De Stefano,Rozie Arnaoutelis,Samson B. Antel,Simon J. Francis,Antônio Carlos dos Santos,Yves Lapierre,Douglas L. Arnold +8 more
TL;DR: The results of this study are consistent with focal pre-lesional myelin membrane pathology in the NAWM at least 12 months before lesions become visible on conventional MRI.
Journal ArticleDOI
Somatosensory-motor bodily representation cortical thinning in Tourette: effects of tic severity, age and gender.
Cherine Fahim,Uicheul Yoon,Uicheul Yoon,Samir Das,Oliver C. Lyttelton,Oliver C. Lyttelton,John C. Chen,John C. Chen,Rozie Arnaoutelis,Guy A. Rouleau,Paul Sandor,Paul Sandor,Kirk A. Frey,Catherine Brandner,Alan C. Evans,Alan C. Evans +15 more
TL;DR: TS revealed important thinning in brain regions particularly involved in the somatosensory/motor bodily representations which may play an important role in tics, in agreement with Leckman et al. (1991) hypothesis.
Journal ArticleDOI
Magnetization transfer can predict clinical evolution in patients with multiple sclerosis.
A. Carlos Santos,Sridar Narayanan,Nicola De Stefano,M. Carmela Tartaglia,Simon J. Francis,Rozie Arnaoutelis,Zografos Caramanos,Jack P. Antel,G. Bruce Pike,Douglas L. Arnold +9 more
TL;DR: The notion that the quantification of MTr in the NAWM can predict the clinical evolution of MS is supported, with data support the notion that lower MTr values predict poorer long-term clinical outcome.
