*Proteinase K-digested PrP fragment size according to the London classification [14, 15].

ND, not done.

All case numbers (first column) are cross-referenced to Figures 1, 2, 3, 4, 5 and 6. The columns on the right describe the pattern of PrP deposition in the white matter. The semi quantitative density scores of white matter PrP are represented in column 8. mo: months, M: male/methionine, F: female, V: valine, WM: white matter, FB = Forebrain, Cer = Cerebellum, T = Threads, D = Dots. The two columns on the right describe the pattern and intensity of cortical PrP deposition as described in [11] and the degree of spongiform changes. S = synaptic, PN = perineuronal net, GR = Granular; P = well demarcated plaques, D = diffuse plaques; and PV = perivascular deposits. The number indicates the semi-quantitative intensity or density of the respective feature.
