Age (years); FUP (follow-up between time points T_previous and T_last, months); EI (Evan’s index, obtained by dividing the maximum width of the frontal horns by the maximum width of the inner table of the cranium at the level of the frontal horns); POR (parieto-occipital ratio, obtained by dividing the maximum width of the occipital horns at the atrium by the maximum width of the inner table of the cranium at the same level); TR (temporal ratio, obtained by dividing the maximum width of both temporal horns at the level of maximal convexity of the hippocampus by the maximum width of the inner table of the cranium at the same level). (ICH-CI) patients with idiopathic chronic hydrocephalus and dementia; (AMSA) asymptomatic or minimally symptomatic adults.
