Tysabri Effects on Cognition and Neurodegeneration in Multiple Sclerosis

Completed · Not applicable

Conditions studied: Multiple Sclerosis

In brief

The long-term objective is to further establish the role of Tysabri in preventing neurological degeneration in multiple sclerosis (MS) and to establish powerful and efficient new markers for neurological degeneration in MS. The study intends to correlate cognition with two instruments and their measurements-MRI and OCT (optical coherence tomography).
