Socio-demographic, clinical volumetric, and brain perfusion features of normal elders enrolled in the study.
| Normal controls | |
|---|---|
| N | 17 |
| Age (years) [Range] | 69.6 ± 3.2 [65 ÷ 74] |
| Gender (females) | 9 (53%) |
| Education (years) [Range] | 9.8 ± 4.1 [5 ÷ 19] |
| MMSE score [Range] | 27.8 ± 1.6 [24 ÷ 30] |
| ApoE ε4 genotype (carriers)* | 1/12 (8%) |
| Left hippocampal volume (mm3) [Range] | 2770 ± 274 [2089 ÷ 3351] |
| Right hippocampal volume (mm3) [Range] | 2715 ± 221 [1881 ÷ 3139] |
| Frontal perfusion (W scores) [Range] | 1.2 ± 0.1 [1.1 ÷ 1.3] |
| Parietal perfusion (W scores) [Range] | 1.4 ± 0.1 [1.3 ÷ 1.5] |
| Temporal perfusion (W scores) [Range] | 0.4 ± 0.01 [0.4 ÷ 0.5] |
| Hippocampal complex perfusion (W scores) [Range] | 0.2 ± 0.01 [0.18 ÷ 0.21] |
| Thalamic perfusion (W scores) [Range] | 0.5 ± 0.02 [0.49 ÷ 0.57] |
Values are mean ± SD for continuous variables or frequency (percentage) for gender and ApoE carriers. Brain perfusion is always expressed as age-corrected scores (W scores).
