Huntington’s Disease (HD) is a neurodegenerative disorder caused by the expansion of CAG repeats on the exon 1 of the HTT gene. Atrophy of the striatum is currently the main biomarker of the disease’s progression, but there is a need to find earlier and more functional biomarkers. Here, we evaluated Diffusion Tensor Imaging (DTI) and resting-state fMRI (rs-fMRI) as biomarkers in heterozygous zQ175 mice, a model mimicking the presymptomatic phase of HD. Our protocol allowed detection of vulnerable brain networks that would be of great interest for better understanding of the pathogenesis in clinical HD.
