Official Title: “A 48-Week, Multicenter, Randomized, Double-Blind, Parallel-Group Evaluation of the Comparative Efficacy, Safety, and Tolerability of Rivastigmine 10 and 15 cm2 Patch in Patients With Alzheimer's Disease Showing Cognitive Decline During an Initial Open-Label Treatment Phase”

The purpose of this study is to support the optimal use of rivastigmine patch in long-term treatment of AD in patients demonstrating cognitive decline at the target maintenance dose of rivastigmine patch.
