Regional cortical thinning in preclinical Huntington disease and its relationship to cognition

Neurology. 2005 Sep 13;65(5):745-7. doi: 10.1212/01.wnl.0000174432.87383.87.

Abstract

The authors studied presymptomatic individuals with the Huntington disease (HD) mutation to determine whether cortical thinning was present. They found thinning that was regionally selective, semi-independent of striatal volume loss, and correlated with cognitive performance. Early, extensive cortical involvement occurs during the preclinical stages of HD.
