Change from Baseline in Integrated Alzheimer's Disease Rating Scale (iADRS)
Baseline, Week 24

iADRS assesses the impact of cognitive loss on everyday activities and provides a measure of global AD severity as a single summary score. It comprises of 2 underlying domains "cognitive ability" and "functional ability," and integrates the items in both the domains a single overall score ranging from 0 to 144, with lower scores indicating worse performance.
