Abstract

This article reviews the use of white-matter changes as identified on MRI as a surrogate marker in clinical trials on vascular dementia. As of yet, insufficient evidence is present to implement rating or volumetric assessment of the burden of white-matter changes as surrogate marker in such trials, in view of the limited sensitivity to change of current methods and the high measurement error.
