Apathy and atrophy of subcortical brain structures in Huntington's disease: A two-year follow-up study

Abstract

The presence of apathy is associated with atrophy of the thalamus in HD, suggesting that apathy has an underlying neural cause and might explain the high incidence of apathy in HD. However, no association was found between atrophy of these subcortical structures and increase in severity of apathy over a 2-year time period.
