W Scores^* in Alzheimer's Disease Patients

	CDR = 0.5 (N = 36)		CDR = 1 (N = 43)		CDR = 2 (N = 15)
Variable
	Mean W Value	SD	Mean W Value	SD	Mean W Value	SD
Total Hippocampus	−1.752	0.939	−1.989	1.193	−2.225	1.183
PHG	−0.874	1.035	−0.996	1.101	−0.512	1.344
Amygdala	−1.026	0.973	−1.337	0.839	−1.355	1.035

^*The W score is the normal deviate relative to controls, adjusted for age and gender. All mean W scores were significantly different from 0 (the expected value for normal subjects), p<.001.

CDR = Clinical Dementia Rating
