Figure 1

Comparison of global brain volumes according to CAG expansion. This figure compares the global brain volumes in three groups of individuals with different CAG triplet expansions: ≤26 (normal), 27 – 35 (intermediate), and >40 (full penetrance). The structures evaluated include the brain parenchyma volume (A), cerebrospinal fluid (CSF) volume (B), gray matter volume (C), white matter volume (D). The p values indicate the statistical significance of the observed differences: (*** p < 0.00001).
