Table 7.

Diagnostic value of dCDT parameters and CERAD total scores in differentiating healthy individuals (HC), patients with amnestic mild cognitive impairment (aMCI) or mild dementia due to Alzheimer’s disease (mAD).

	HC vs. mAD			aMCI vs. mAD
	Sensitivity	Specificity	Accuracy	Sensitivity	Specificity	Accuracy
dCDT	91.5^a	94.2^a	93.0^a	69.8^b	89.9^b	81.2^b
CERAD total score	88.7^c	94.9^c	92.3^c	76.4^d	81.4^d	79.2^d

HC: healthy control individuals; aMCI: amnestic mild cognitive impairment; mAD: mild dementia due to Alzheimer’s disease; dCDT: digital Clock Drawing Test; dCDT variables in the regression model: ^aTime in air and CDT score; ^btotal time, pressure/velocity relation, strokes per minute, and CDT scores; CERAD = Consortium to Establish a Registry for Alzheimer’s Disease neuropsychological battery. ^cCERAD total score cut-off 66.0 points; ^dCERAD total score cut-off 58.0.
