Early atrophy of pallidum and accumbens nucleus in Huntington's disease.

ABSTRACT: In Huntington's disease (HD) atrophy of the caudate nucleus and putamen has been described many years before clinical manifestation. Volume changes of the pallidum, thalamus, brainstem, accumbens nucleus, hippocampus, and amygdala are less well investigated, or reported with contradicting results. The aim of our study is to provide a more precise view of the specific atrophy of the subcortical grey matter structures in different stages of Huntington's disease, and secondly to investigate how this influences the clinical manifestations. All TRACK-HD subjects underwent standardised T1-weighted 3T MRI scans encompassing 123 manifest HD (stage 1, n = 77; stage 2, n = 46), 120 premanifest HD (close to onset n = 58, far from onset n = 62) and 123 controls.
