- All data except age are n (%)
- iNPH, idiopathic normal pressure hydrocephalus; VaD, vascular dementia; PSP, progressive supranuclear palsy; MSA-P, multiple system atrophy parkinsonian type; HC, healthy controls; enl., enlarged; DESH, disproportionately enlarged subarachnoid-space hydrocephalus; EI, Evans’ index; ns, not significant
- aKruskal Wallis. Mann–Whitney was used as a post hoc test between each group and revealed that there was a significant difference in age between MSA-P and all other groups (iNPH vs MSA-P, p = 0.005)
- bχ2 test. All imaging markers were more frequent in iNPH than in the other groups
