This Article contains errors.

In Table 1, the heading ‘Hand MMT [0–5]’ should read ‘MMT [0–5]’. In addition, the disease durations of subjects 6 and 9 were incorrectly given as ‘10’ and ‘20’ years, respectively. These should read ‘38’ and ‘21’.

In Figure 3c, the upper limit of the colour bar is incorrectly given as ‘20’, and should read ‘65’. The figure legend is correct. The correct Figure 3 appears below as Figure 1.
