Human prion diseases (transmissible spongiform encephalopathies) are progressive and fatal neurodegenerative disorders. Voxel based morphometry (VBM) has only been used to study prion disease pathology in cross sectional studies. Only whole-brain ry measures have been employed to assess progressive degeneration longitudinally. Here we followed up a large numbr of prion disease patients with serial cerebral MRI and applied longitudinal VBM to characterize progressive structural change. We reveal significant regional changes in brain atrophy in prion patients consistent with known prion pathology and show correlation of rates of structural change with change in clinical assessment scores.
