Trial Outcomes & Findings for Effects of Dalfampridine on Cognition in Multiple Sclerosis (NCT NCT02006160)

NCT ID: NCT02006160

Last Updated: 2020-10-01

Results Overview

The Symbol Digit Modalities Test is a measure of cognitive processing speed. The outcome is the total number of correct digit substitutions in 90 seconds, with a possible total range of 0-120. Higher values reflect a better score/outcome than lower scores.
