Demographics, risk factors and behavioral scores
| Younger adults (n = 29) |
Older adults (n = 34) |
p-value | |
|---|---|---|---|
| Age (Years) | 24.14 (3.9) | 77.03 (7.0) | < .001 |
| M/F | 12/17 | 15/19 | .748 |
| Education (Years) | 16.6 (2.1) | 16.6 (2.4) | .928 |
| APOE ε4 | - | 24% | - |
| BMI | - | 26.4 (4.7) | - |
| Systolic BP | - | 137.2 (12.6) | - |
| Diastolic BP | - | 76.6 (10.7) | - |
| Corrected Recognition | 0.94 (0.07) | 0.86 (0.10) | < .001 |
| Reaction Time (ms) | 543 (62) | 723 (86) | < .001 |
M/F: male/female; APOE ε4: percentage of older adults with one or more APOE ε4 alleles; BMI: body mass index; BP: blood pressure. Values represent means (standard deviations) for continuous variables and either ratio (M/F) or percentages (APOE ε4) for categorical variables. Data was missing for APOE ε4 (26%), BMI (17%) and BP (17%). P-values were calculated from independent samples t-tests, except for M/F, which was calculated from a Chi-square test.
