Table 1: Ratings of the white matter hyperintensities modified from CREDOS The periventricular hyperintensities and the deep white matter hyperintensities were separately evaluated and the results were combined to give a representative rating of the WMH as ‘minimal, moderate’ and ‘severe’. CREDOS, Clinical Research for Dementia of South Korea; D, rating of the deep white matter hyperintensities; P, rating of the periventicular hyperintensities.
