Detailed Description
Eligible patients entered this 50 week multicenter, double-blind, randomised, placebo-controlled, parallel group study which evaluated the effect of Sativex on cognitive performance. At each scheduled clinic visit, patients were assessed for cognitive performance, mood, severity of spasticity, use of investigational medicinal products and number of visits to a healthcare professional. Primary efficacy comparisons were made between scores recorded during baseline and scores recorded at the end of treatment.
