“ Since VBM analysis is a conservative method, as no a priori region of interest is studied, we postulate that damage in this region is common to all patients while the regional evolution of the neurodegenerative process may be more variable across PD patients, and hence lowers the sensibility of white matter VBM analysis in other brain regions. It is also likely that later stages of the disease affect grey matter more significantly but in a more heterogeneous way. ”
