Current Primary Outcome Measures  ICMJE
 (submitted: August 4, 2017)
Change in Cognitive Function Over Time [ Time Frame: Baseline, 48 weeks, 96 weeks ]
Cognitive function was assessed using the oral version of the Symbol Digit Modalities Test (SDMT). The number of correct responses in 90 seconds was recorded (possible range 0-110). For analysis, SDMT scores were converted to z-scores using published age and education based norms. A negative z-score indicates a SDMT score below the mean based on the age and education based norms, for example a z-score of -2 = 2 standard deviations below the mean; a positive z-score indicating a score above the mean. Higher scores indicate better cognitive function.

specific MRI parameters and RNFL (retinal nerve fiber layer) thickness in OCT optical coherence tomography in correlation with cognition measurements [ Time Frame: 2 years ]

Current Secondary Outcome Measures  ICMJE
 (submitted: September 22, 2017)
  • Change Over Time in Retinal Nerve Fiber Layer Thickness [ Time Frame: Baseline, 24, 48, 72, and 96 weeks ]
    Retinal Nerve Fiber Layer (RNFL) thickness was measured using spectral domain OCT scans by a trained technician. Scans were performed without pupil dilation.
  • Change Over Time in Brain Parenchymal Fraction [ Time Frame: Baseline, 48 weeks, 96 weeks ]
    Measured based on MRI scan on a 3T Phillips scanner. This is a measure of brain atrophy (i.e., brain volume loss) with lower values indicating greater atrophy (possible range 0-1).
  • Change Over Time in Normalized Thalamic Volume [ Time Frame: Baseline, 48 weeks, 96 weeks ]
    Measured on MRI scan
  • Change Over Time in Normalized Hippocampal Volume [ Time Frame: Baseline, 48 weeks, 96 weeks ]
    Measured on MRI scan

Descriptive Information
Brief Title  ICMJE Tysabri Effects on Cognition and Neurodegeneration in Multiple Sclerosis
Official Title  ICMJE Tysabri Effects on Cognition and Neurodegeneration in Multiple Sclerosis
Brief Summary 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).
Detailed Description

The specific aims are:

  1. To determine the effects of Tysabri on cognition (memory, thought processes, etc.)
  2. To determine the effects of Tysabri on specific MRI markers for cognitive dysfunction
  3. To determine the effects of Tysabri on retinal nerve fiber layer thickness (RNFL) using optical coherence tomography (OCT), a special instrument used in ophthalmology
