A Quick Test of cognitive speed is sensitive in detecting early treatment response in Alzheimer's disease

Table 1 Mean MMSE and AQT values ± standard deviation

Variable	8 weeks before baseline^e	Baseline	8 weeks after baseline
	n = 75	n = 75	n = 75
The MMSE, points	23.0 ± 3.1	22.7 ± 3.0^a	23.3 ± 3.5^b*
AQT Color-Form, seconds	98.8 ± 21.6	101.5 ± 24.9^c*	91.8 ± 28.4^d*

^aP = 0.088 compared with 8 weeks before baseline. ^bP = 0.047 compared with baseline. ^cP = 0.045 compared with 8 weeks before baseline. ^dP < 0.0001 compared with baseline. ^eCalculated value for all 75 patients according the description in Materials and methods. *Significant change.
Calculated with the Wilcoxon test. MMSE, the Mini-Mental State Examination (0 to 30 points); a higher score indicates better cognition. AQT, A Quick Test of cognitive speed (measured in seconds); less time indicates better cognition.
