Table 2.
Clinical, neuropsychological, and demographic characteristics of healthy control individuals (HC) and patients with amnestic mild cognitive impairment (aMCI) with normal clock drawing scores (i.e. a score of 1 or 2).
| Group | p-value | ||
|---|---|---|---|
| HC | aMCI | ||
| n = 137 | n = 95 | ||
| Age in years | 69.6 (7.8) | 69.6 (8.7) | 0.967 |
| Years of education | 13.2 (2.7) | 12.9 (2.9) | 0.622 |
| Gender (F[%]/M[%]) | 60[44]/77[56] | 42[44]/53[56] | 0.950 |
| GDS | 2.7 (2.6) | 2.8 (2.8) | 0.756 |
| MMSE | 29.1 (0.9) | 26.7 (1.9) | <0.0001 |
| CERAD total score | 83.6 (9.5) | 68.9 (10.8) | <0.0001 |
Values are displayed in mean (standard deviation); n = number; HC: healthy control individuals; aMCI: amnestic mild cognitive impairment; F[%]/M[%] = number and percentage of female/male; GDS = Geriatric Depression Scale (a higher score indicates more severe depressive symptoms; maximum 15; scores of >5 indicates depression); MMSE = Mini Mental State Examination; CERAD = Consortium to Establish a Registry for Alzheimer’s Disease neuropsychological battery.
